How to make a bag on wheels with your own hands

Shopping bag on wheels - choosing a cart for groceries

Suitcases and travel bags on wheels will not surprise anyone. But we don’t go on trips that often, and buy groceries every day. It’s easier for those who have a car - you can bring groceries from the supermarket using a “local” cart. But there is nothing like it on the market. We have to carry numerous heavy bags in our hands. And not everyone has a car. Those who do not have an iron horse have to cut off their hands more often. The solution is a shopping bag and a trolley on wheels. These are far from those clumsy carts from the end of the last century. Modern models are quite attractive and can make life easier and maintain health.

Types of components

There are a large number of breakdowns that can occur in any suitcase, regardless of the manufacturer, design, or model of the product. Even the most minor problems, for example, damage to a zipper or clasp, can cause a lot of discomfort or even make it impossible to use this important attribute for travelers. To carry out repairs, as well as replace individual parts or entire structures, appropriate spare parts for a suitcase on wheels are required. Among the main components of a travel bag are the following elements:

retractable systems;
wheels and wheel blocks;
pens;
legs, stands;
locks, cases;
runners;
lightning.

Obviously, fittings for suitcases are presented in a wide range and it is advisable for the owner of such a thing to understand the design of the product. This will help not only to correctly localize and diagnose the breakdown, but also to repair or replace it yourself without high costs.

Back in trend

“Kravchuchki” - old-style carts - are not very pleasant to use, although they are convenient. They can still be seen in the hands of old people. Whether beautiful or not, they are unable to pull a load in their hands. However, more and more often we began to come across interesting shopping bags on trolleys. And they look good, and they seem more comfortable than old bags fastened with belts and elastic bands. And they are used by far from old and very good-looking people. Gradually this ceases to be surprising. After all, heavy packages do not improve your health, and the appearance of those pulling packages with provisions in their hands is appropriate - a person puffing from the effort does not look any more attractive than someone who is simply pushing a cart.

The shopping trolley bag on wheels is back in trend

This fashion for trolley bags came to us from the West. Despite the fact that almost everyone has a car, every family has a bag on wheels. And not only the elderly, but also the young use them. Carrying a bunch of packages around the same shopping center is not very convenient. It is much more convenient to put all your purchases in a cart. Yes, it’s still better to take care of your arms and back - treatment is expensive. In general, the shopping trolley bag is becoming increasingly popular.

Frame and its features

So, it seems, what could be so complicated in a shopping bag? Take any one and you will be happy. But no. There are many features that determine how convenient it is to use. And it’s not about the colors at all, but about the boring but important details. Let's start looking at possible designs of a trolley bag. They can be:

One possible use is to transport using a bicycle

A trolley bag - with or without a frame - really reduces the strain on your arms and back. Which one is better? There is one for each purpose. If you only go grocery shopping purposefully and only from home, the best choice is a frame one. If you travel by public transport, a folding one is more suitable. When folded, it takes up little space. If you walk, then a stationary one is also suitable - it is more reliable and durable, since there are fewer connections.

If you come for provisions after work, then few people will want to carry a cart with a bag to work. In this case, a bag on wheels without a trolley is more suitable. When folded, it takes up little space - like a medium-sized cosmetic bag.

Frameless shopping bags on wheels

Wheels are attached to the bottom of the frameless trolley bag. They can be on a single platform, or each separately. As a rule, there are two or four wheels. If there are two wheels, there are additional stops that give the cart stability. The wheels have a small diameter and the width of the “tire”. The bag can hold 10-15 kilograms of food.

The advantage of this type of trolley bag is its compactness when folded and low weight. But they only drive well on flat surfaces and with a light load. When carrying a significant load, a significant load is placed on the arms and back. In general, this is a good option if you need to carry a load a couple of hundred meters. To the car, for example.

A frameless shopping bag on wheels is very compact when folded (this is that small light green package on the right)

When choosing, make sure that the trolley bag has reliable stops. In cheap versions, these are two thin twigs. Firstly, they may not be able to hold the load, and secondly, they will stand unsteadily. The width of the handles and the height of the entire structure are also important.

Types of frame

Shopping frame trolley bags have a greater carrying capacity. The frame can be made of steel or aluminum alloy. Those with an aluminum trolley weigh less (from 1 kg to 1.5 kg) and can transport loads with a total weight of up to 30 kg. Most often they are not painted - aluminum itself looks quite normal.

Frame ones are also different

The steel frame is more durable, which allows you to transport up to 50 kilograms of products. But the trolley bag itself weighs more than two kilograms. Since steel rusts, it is coated with paint or a layer of corrosion-resistant metal.

You should also pay attention to the following parameters:

One retractable handle is too unstable. Bad choice for older people

In fact, the height of a trolley bag is one of the most important parameters. If it is too low, you will have to bend over and strain your body while moving. If it is too high, there will be a lot of stress on the arm.

Description and scope of application

Trolley shopping bags on wheels came into widespread use in the early 90s . They turned out to be very convenient for transporting large quantities of goods when enterprise played a decisive role. This item became a kind of symbol of the era.

Since then, many modifications have appeared. For comfortable climbing stairs, the device can be equipped with two handles and several rows of wheels. Only one detail remains unchanged: the platform on a metal frame .

For more details, watch the video below:

The design allows even a fragile person to deliver home purchases in the required volume. Women don't need to risk their health by lifting weights when they have an elegant, stylish rolling bag at hand.

There is always a use for this item:

shopping without regard to the weight of purchases
a trip to the dacha or to visit relatives in the village
the opportunity to provide courier services or save on delivery of a parcel to your home by picking it up yourself from the post office
trips

How to choose a bag Most models are quite versatile, but it still makes sense to focus on basic needs. Pay attention not only to the design of the frame, but also to the capacity .

The bag can be:

removable,
fixed

Many housewives prefer the first option, since a removable bag is much easier to wash . There will be no difficulties when transporting a bulky item whose parameters exceed the dimensions of the container.

In such cases, you just have to take care of another method of fastening, for example, using a rope.

There is no consensus regarding the waterproofness of the material. The waterproof option is certainly good in slush, but quickly becomes unusable at low temperatures, which is why in northern latitudes simple fabric is more practical.

Canvas trolley bag

A number of manufacturing companies also offer universal materials: tarpaulin, modernized burlap, polypropylene. A wide variety of options allows you to take into account climatic conditions .

Domestic and foreign manufacturers offer a variety of modifications - from the simplest, for going to market, to “reinforced” versions with increased load capacity. These models are used primarily for delivery of goods or auto parts from a warehouse.

A manual platform cargo trolley is often equipped with a special box to give the contents stability. You can read about them in this article.

When purchasing any tool, everyone wants it to last as long as possible. In order not to make a mistake with your choice, find out here which chainsaws are the most reliable.
Proper operation can extend the life of a chainsaw. For example, before starting a chainsaw for the first time, it is necessary to run it in.
To start the chainsaw correctly, first read the instructions and our article - here.

Number of wheels

The degree of load on the hands when moving loads depends on the number and size of wheels in the trolley bag. To make it convenient for you to transport cargo, the diameter of the wheel should be 15-20 cm. No less. In this case, pay attention to the width and material of the “tire”. The width should be at least a centimeter, but it is better if it is larger. Narrow wheels often fall through and get stuck, making movement difficult. The tire must be made of elastic rubber. Round or corrugated - whichever you prefer, but rigid and elastic.

Next, let's look at how many wheels a shopping bag and trolley can have. The stability and load that falls on the arms and back when moving depends on this.

Shopping bag trolley on wheels: four wheels are stable and reliable

Shopping trolley with six wheels

So how many wheels should a trolley bag have? If you need to lift a load up stairs (Khrushchev and Stalin buildings), the best choice is six wheels. They really work and make the task easier. If the cart will be used by an elderly person, it is better to choose a four-wheeled one. She, in fact, is “lucky herself.” You just need to push it a little. While on a two-wheeler, part of the weight is still transferred to the hand.

Materials and tools

Before you start work, you should stock up on all the necessary tools and materials. The list basically contains few items, since the product is not particularly complex in design:

Silk threads to match the color of the main material. These threads can be used to reliably sew any type of fabric.
Thread and needle or safety pins to use for pre-assembling the pattern.
Ruler (measuring tape), chalk (pencil), Whatman paper. All this is needed to prepare the pattern.

Shopping bags

For finishing stitching, it is better to use a sewing machine. Then the stitches will be neat and uniform. This will significantly affect the appearance of the product.
If you use thick fabric, you may need an awl.
The main thing is the fabric. One type of textile or several can be used - it all depends on the complexity of the chosen model.

Additional Information ! To sew a patch pocket inside or outside, or to make a lining, you should choose a fabric with a print.

Suitable fabrics

Additional fittings may be required. Usually these are rivets, buttons, carabiners or zippers. Such little things serve as fasteners.

The quality of the material of the bag itself

The bag itself should be made of dense, durable material. It is desirable that it be water-repellent, so there is no fear of rain and snow. The best option is synthetic fabrics; they are also easy to clean. For example, polyester fabric has good performance properties. At the moment it is considered the best.

You need to pay attention to the bag and the way it is attached to the cart.

There are also materials with thermostatic properties. Such properties are useful in the summer - so that food does not heat up in the heat. But this is rather a bonus if you have the funds for it. Pay attention to additional pockets and bottle holders. These simple and inexpensive features make the thing really easy to use.

Bag volume and clasp

What you should pay attention to is the size of the bag. But it must match the load capacity of the trolley. The volume is usually indicated in liters:

The size of the bag must match the trolley

There are options in which the neck can be folded out. These can be reduced or enlarged as desired (the upper part turns inward). There are two types of fasteners - a drawstring fastener and a Velcro or magnetic clip flap. Often there can be two types of fasteners - so that during transportation no precipitation gets inside the bag, and so that everything remains safe.

Method of attachment to the frame

Also pay attention to how the bag is attached to the frame. There are models in which the bag is removable. In this case, the trolley can be used to transport goods in its own container. If you are interested in this option, make sure that the cover is easy to take off and put on, but at the same time, that it is securely fixed. There are two options:

How the bag is attached to the trolley

In general, the Velcro fastening is secure and comfortable. You just need to have a sufficient area of the Velcro - there is a lot of weight to be held.

Classics of the genre

During testing, a standard reinforced device can withstand a load of 100-130 kg. Increased strength is achieved due to welded connections (as an option, a bolt-nut instead of a traditional, but not always practical rivet) and a galvanized pipe diameter of 15 or 16 mm.

However, manufacturers warn that constant operation in wear-and-tear mode will shorten its service life. The optimal transportation weight is 70-80 kg. When unfolded, the dimensions of the trolley are on average 1015x465 mm; in its most compact state it takes up 620x325 mm.

The design of the bag provides for maximum mobility : it is equipped with standard handles, which make it very convenient to pick it up along with the trolley when boarding a vehicle. The most common material is polyester: it is wear-resistant and easy to care for.

The metal base is covered with an additional protective layer of special paint. Other models of bags on wheels have become an indispensable attribute of a trip to the supermarket or a long trip. Through the efforts of designers, they have become a real trend, successfully combining an attractive appearance and obvious comfort.

Classic trolley bag

The metal frame takes on the lion's share of the load when climbing stairs , overcoming curbs and other road obstacles. Thanks to the light hand of the developers, the seemingly simple design provides many options for both the bags themselves and ways to attach them to a metal base.

You can purchase metal fixtures without any additional equipment. This is a wise choice if you plan to transport multiple boxes, backpacks or bags. The frame structure provides many options for fastening using ropes or belts.

Special models

A shopping trolley bag on wheels can have a folding seat. This option is good for those who travel to the country and who have to wait a long time for transport. A very good option. A chair, of course, is not a chair, but sitting is better than standing. Especially children or elderly people.

Special types of trolley bags: with a folding chair and for bicycles

The second special type of trolley bags is for bicycles. They are distinguished by a more massive frame, greater volume and load capacity. More reliable and wider wheels. To avoid problems with transportation, the wheels must be at least 20 cm in diameter, and must also be on rolling bearings.

Features of suitcase wheel repair

How does this usually happen? The holiday season is coming, you are getting ready for a great vacation in an interesting place. And then a last minute tour turned up for ridiculous money and with great conditions. We must fly! And just a day was allotted for getting ready. Well, okay, now we take the suitcases from the mezzanine and... That's right, there was a problem with securing the wheel. And the wheel itself has disappeared somewhere, but where...

In general, there is no time and especially no desire to look for a workshop, we need to get ready. So you can try to repair the suitcase wheels yourself.

What you may need:

Screwdriver
,
Keys
,
Pliers, pliers
,
Wheels
(life hack - wheels from rollers; in rare cases, wheels from furniture may be suitable. But it is from rollers, when choosing the right size, that they fit perfectly into standard mounts),
Drill and screws
(optional).

First you need to understand what type of fastening your suitcase has. When you clarify this, you will need to either remove the entire assembly part, or just the broken part. As a last resort, the old fastener can be knocked down and a new one installed in its place.

If the repair was carried out in a hurry, we still advise you to contact competent specialists after the trip.

Or even choose a new suitcase if the old one is already quite worn, worn out and has lost its former attractive appearance.

If the fasteners do not fully match the measurements, you can almost always correct the situation. That is, if it is too narrow, drill it out, and if it is wide, fix it. But the difference in size should not be too significant. To secure the wheel in the mount, you can use locknuts, metal plates, etc. Although here, as you can see, additional parts and tools will be needed.

Travel bag

The bag is designed for delicate transportation . It is equipped with a metal frame not only on the outside, but also on the inside. Wheel rims of increased elasticity serve as springs. You can safely transport fragile items in a travel bag without fear for their safety

The bag is stable, it has a ribbed inner covering that is springy, softening external mechanical influences. There are compartments and pockets with decorative fasteners on the outside and inside.

Frame and its features

One possible use is to transport using a bicycle

Small details

The very first test confirmed the reliability of Velcro fasteners. Under the influence of a load of 18.5 kg. one of the parts supporting the horizontal shelf of the cart was deformed. Thus, the weight of the entire load fell on the top Velcro fastener installed on the handle of the bag. However, despite the accident, I was able to successfully deliver the cargo safe and sound.

In order to provide reliable support for the horizontal shelf of the cart, the design of the cart folding mechanism has been slightly improved.

The stop supporting the horizontal shelf of the cart was fixed using two clamps, which now limit the movement of the stop along the wheel axle of the cart.

Using two M3 screws, a small polypropylene cracker was fixed to the pipe of the horizontal shelf of the trolley, which ensured greater rigidity of the trolley structure when unfolded. Now the stop, instead of bending the five-millimeter rod of the folding mechanism, rests against the twelve-millimeter pipe of the horizontal shelf of the trolley.

All holes in synthetic woven materials were made using a soldering iron tip, which was previously given a conical shape.

Popular manufacturers

At the moment, as already mentioned, there are a lot of different options for folding carts, both with and without bags. Particularly notable in the assortment are folding trolleys made in Finland and Germany. They are represented by the following companies: Andersen Shopper, Reisenthel Foldabletrolley hopi, Akubens, Ananda, Baolu. A special feature of such trolleys is the ability to remove the bag and turn it into regular hand luggage, which is very convenient, for example, when loading it into a car. The frame of the carts is durable, made of metal, and it is completely foldable. The handle, as a rule, is covered with pleasant plastic, which will increase comfort when moving.

Also market favorites are models produced in Sweden and Russia. These are the companies Biltema, Red Cat, Pamby, Bison and others. Such designs help distribute the weight of the luggage throughout the trolley structure, making transportation easier. Such carts will be relevant for those who deal with heavy loads every day.

Here are examples of some trolley models:

Number of wheels

Next, let's look at how many wheels a shopping bag and trolley can have. The stability and load that falls on the arms and back when moving depends on this.

Trolley bag pattern

Patterns for shopping bags are simple. Even the model for the trolley is made on the basis of a simple pattern. Its only difference is that the size of the accessory is noticeably larger than other shopping bags. The material for such a bag should be quite dense and rough.

In order not to rack your brains about how to make a pattern correctly, you can use a ready-made sketch, taking the necessary measurements directly on the fabric. Usually, the dimensions of each part are indicated on the pattern itself.

The difference between sewing models is small:

The workpiece is cut out in accordance with the template.
Fold along the fold and form sidewalls from a single piece of fabric.
For convenience, a valve is added on top.
If desired, you can trim the seams with contrasting trim.

In some cases, an envelope bag pattern is also suitable for such a bag, with the only difference being that you will need to create volume on the sides so that the product is not flat.

To learn how to quickly sew a product, watch the following video.

Types of trolleys

Ordinary car

It is one of the simplest hand carts and was originally conceived as a one-wheeled device. It was invented several thousand years BC and is still very popular among people. With its help, the White Sea Canal, the Dnieper Hydroelectric Station, the Trans-Siberian Railway, Egyptian pyramids, modern cities and other magnificent structures, striking in their grandeur and uniqueness, were built.

The first wheelbarrows had everything made of wood: wheels, body and handles. With the modern development of industry and nanotechnology, the car has noticeably changed. It has a streamlined iron body, steel shaped handles with plastic ergonomic handrails and a rubber wheel. Of course, there are more advanced analogues that have two wheels. Compared to the first ones, they are much more practical and therefore sell out at lightning speed. They are used mainly at dachas for transporting gardening tools, bulk materials and harvest fruits.

Making such a tool cart with your own hands is not difficult at all, especially when you have a drawing or photo. To do this, you need to visit the nearest scrap metal collection point and buy two smaller bicycle wheels, a suitable axle for them and a pipe with a diameter of 20 mm and a length of 2.5 m for the handle. Connect everything purchased using wooden blocks, as well as screws, nails and various overlays. The body box itself can be made from an unnecessary zinc bath. At first, this design will work quite well. She will be an excellent helper in the garden and in the dacha garden.

After a month-long test, it is necessary to correct or modify some components and mechanisms of your favorite cart. For example, instead of a bathtub, make a three-dimensional box from plywood using wooden blocks and screws. Improve the handle, attach the step to the cart, and who knows what else. You can decorate the sides of the body with 3D drawings or simply paint them in different shades.

Two-wheeled trolley

Often households need a regular folding cart for transporting goods. This is a very convenient thing for trips to the nearest building materials store. You can easily carry a bag of cement or several cans of paint on it. At the farmstead, it is used to transport gas or other blocks closer to the construction site. It is also possible for a special purpose, for example, for a heavy welding machine. In addition, when folded, it becomes compact and convenient for traveling on household errands.

It is more difficult to make such a cart for moving goods with your own hands, but it is still possible with only a small set of tools. To do this, you will need an axle and two wheels with a diameter of no more than 30 cm from a children's bicycle, a 30x30 mm corner or a 15 mm pipe. In the simplest design, only the handles and the cargo grid will be folded.

Useful tips for sewing fabric bags

Each design of any bag provides the basic foundation, but there are some secrets that will help make the item more practical and durable. If you use them in the process of sewing a shopping bag, then the item can serve for many years without losing its practicality.

Helpful Tips:

Before you start sewing, you should check the fabric for shrinkage, the quality of the dye and the features of the fabric. A small piece of material should be washed and waited for it to dry, after wrapping the still damp cloth in white cotton. Then compare the resulting sizes with the initial ones. The next step is to check if the white fabric has become stained. If a lot of threads are frayed on the cuts, and the fabric itself is divided into fibers, then there is no point in working with such fabric.
To strengthen the seams, you can sew a cord into the hems when overlaying or sew them on top with a strip of thick fabric.
Decoration can be reduced to gluing a thermal sticker onto the main canvas. Such decoration can always be changed, and you won’t have to bother with it for a long time.
In the process of forming the pattern, you should not forget about adding fabric to the seam allowances. If this is not done at this stage, the product will turn out smaller than expected.
When preparing a pattern or fabric pattern, you need to carefully monitor the direction of the fabric thread. If each part has a different direction, the product will be deformed during the sewing process.
The practicality of a bag for household needs is determined by its ease of use. You should not reload the product with decor, which will only get in the way.

Features of tailoring
If you take into account all the tips during the work process and adhere to them, the product will turn out beautiful, correctly shaped and practical.

For your information! It should also be taken into account that such an item in the outfit of a housewife going to the market to buy groceries is still not a handbag, and excessive decoration is simply out of place here.

Finished bag

In order not to carry purchases in unreliable bags, which are also expensive, you need to sew a special shopping bag. Making a home accessory can be done without any extra costs and time if you choose a simple model and use old clothes as the material. Usually, sewing such a thing takes no more than 1–2 hours.

Cargo utility cart on wheels

The design and number of wheels have a significant impact on performance characteristics. When choosing the appropriate option, you should first decide on the purpose of the purchase. Thus, a cart for transporting logs will have larger dimensions than a model intended for shopping.

A large assortment will allow you to choose the optimal model

Two-wheeled trolleys for transporting goods: the best option for working in the garden

When working on a personal plot, you have to constantly move various objects from place to place. A two-wheeled trolley for transporting goods helps to facilitate this process. With its help, you can transport bulk materials, boxes or buckets over a relatively short distance.

Device and technical parameters

Product designs may vary. Manufacturers offer to buy a two-wheeled garden cart with a transverse or longitudinal handle. Models with a cross handle can be pushed in front of you or pulled behind you.

Advantages and disadvantages

The advantages of two-wheeled utility carts include:

Three- and four-wheeled carts for transporting goods

If the weight of the items being transported exceeds 300 kg, a three- or four-wheeled trolley will be required to transport goods. Such structures are indispensable when transporting bulky and large-sized products. We invite you to get acquainted with their design features, advantages and disadvantages.

Design features and technical parameters

Manufacturers offer models that differ in the following indicators:

The platform is made of mesh, solid, frame. The first type is relevant when transporting large, heavy cargo. Due to its design, the mesh platform has less weight compared to other types, which greatly simplifies transportation. To manufacture products with a solid platform, stainless steel is usually used, which is covered with a layer of liquid rubber on top to prevent objects from slipping during transportation.

Advice! To transport a large number of small items, it is better to choose a model with mesh or frame sides.

Wheels can be solid rubber or pneumatic. The first ones are relevant when moving the structure on a flat floor indoors. The latter are suitable for transporting cargo inside and outside the building.

Advantages and disadvantages

The advantages of four-wheel carts on plastic wheels include:

Disadvantages include low productivity and high labor costs in mechanical models. Hydraulic ones do not have this disadvantage and are capable of transporting a weight 100 times greater than their own. However, they are more expensive.

Folding hand utility carts on wheels

If you only need a hand truck occasionally, consider folding models. Having the same advantages as conventional designs, they can be folded at any time for convenient storage in a closet or pantry.

Device and technical parameters

The main technical parameters of folding models include:

The method of fastening the wheels has a significant impact on the ease of use of such products. High-quality models are quite maneuverable and can be used to transport cargo along uneven paths.

When folded, the structure takes up less space

Patterns for a shopping bag

The pattern of a shopping bag can have completely different options - each model has its own characteristics and is designed to perform certain functions. In order not to complicate the process of creating an item for household needs, you should choose the simplest forms. This is a string bag, which is also called a sack.

Important ! Before choosing a string bag model, you should immediately decide what kind of fabric will be used.

Step-by-step algorithm for creating a pattern on fabric for such a model:

You need to prepare a strip of fabric with dimensions of 50 cm by 130 cm.
The left edge needs to be folded up so as to align it with the side of the strip.
Fold the right edge from above to the bottom according to the same principle as the left.
A square will remain in the center, and triangles will form along the edges.
Select a diagonal in the central square. Bend the piece along this diagonal.
Fold the pattern according to the indicated diagram.
Iron the workpiece in the assembled state to fix all the necessary bends.
