Do-it-yourself hydraulic valve for removing the engine

Design features and operating principle

The hydraulic valve is made of durable metal and has a stable design. The main principle of the mechanism structure: stable support with low dead weight. This helps you lift loads of up to three tons with ease, but a maximum of two meters above the ground.

Garage crane is used for:

• removing the engine;
• lifting beams, bridges;
• movement of dimensional units.

The crane contains a hydraulic drive and operates through a system of communicating vessels. The method allows you to make the rise smooth.

Stationary

The stationary crane is installed in large car repair shops and is securely attached to a monolithic foundation. The mechanism has a boom with a rotating system and is equipped with a manual drive. Allows you to work on only one vehicle at a time.

It is important to calculate the installation location in advance, since it will not be possible to dismantle the structure without loss.

An integral advantage of a stationary crane is its large lifting capacity. It is provided by a monolithic support, which creates rigidity of the system.

Portable

The hydraulic rolling crane has wheels on its base. The support is provided by the lower metal beams, which results in loss of load capacity readings. It is better to choose a faucet with a massive triangular support. By design they are divided:

• on cast solid supports with limited boom reach, but good load capacity;
• telescopic or folding - they have an increased boom reach, but reduce the load capacity by several times.

Important! Folding units need to strictly follow the instructions for lifting the permitted load. The arrow cannot withstand and, if the permitted standards are not observed, it breaks off.

How to use

The telescopic boom of the mechanism can be installed in several positions. The goose is maneuverable and can be controlled by 1 person. The equipment lifts quite heavy loads due to the installed jack; no additional accessories or devices for moving heavy loads are needed.

In order to raise the car engine, you need to open the hood and roll up the crane. It is installed so that the legs are placed under the machine, and the chain with the hook hangs over the engine.

The engine has eyes, cables are hooked onto them, and a chain with a hook is connected to them. Having installed the pry bar, pump the jack. He raises the boom, and the engine goes up with it.

After the repair of the machine is completed, the motor is lowered into place and the hook is removed. The crane is rolled away from the car. If necessary, it can be disassembled.

Main types of equipment

The average garage has a reduced square footage and requires careful selection of equipment. Before installation, it is recommended to carefully study the need for individual mechanisms, their types, pros and cons. A hydraulic valve is determined by two criteria.

By type of drive

There are also two subtypes of hydraulic drive:

• automated design with hydraulic cylinders;
• combined, with hydraulic cylinders and manual winches.

A significant drawback of the first is oil cylinders. They need frequent regular replacement, so this design is considered extremely unprofitable for constant use. The combined system will last longer. However, some of the work with winches will have to be taken on by mechanics.

According to the design of the support

Hydraulic cranes are divided into mobile and stationary, they can be folding and prefabricated cast (goose). For ordinary garages, it is more rational to choose a mobile structure with folding parts.

What characteristics should a garage lift have?

Since the device will be used in the rather cramped conditions of a standard garage, certain requirements are put forward for it.
Firstly, it should not be too large - such a car lift, despite its high power, takes up a lot of space, which is very undesirable in such a small area. Secondly, it is recommended to give preference to mechanisms with a small vertical stroke, otherwise you risk running into the ceiling. The second requirement is carrying capacity. It is calculated based on the types of work for which the car lift is being developed. The dimensions of the mechanism also depend on the purpose. If a regular jack is suitable for regular wheel replacement, then for larger-scale work you will need a car lift with a platform, although for such important actions it is recommended to resort to the help of professional equipment.

DIY crane assembly technology

If you have certain skills, assembling the mechanism yourself will not be difficult. To do this, it is important to draw up a preliminary design drawing, choose materials wisely and strictly follow the assembly instructions.

Schemes and drawings

Below are sample drawings of a hydraulic crane. You need to make accurate calculations yourself, based on the parameters of a particular garage.

Material selection

To build a garage lift yourself, it is recommended to first purchase all the required materials:

1. 3 steel corners with parameters 7.5x7.5x0.8 centimeters.
2. “Worm” gearbox, the minimum load capacity of which starts from 300 kilograms, and the additional indicator is 60 kilograms.
3. A strong steel plate one centimeter thick. If you have an old metal cutting machine, you can take it from it; you won’t need outside help for this.
4. About 10 matching bolts.
5. 2 dense metal chains with a diameter of two to three centimeters. The crane is designed to work with very heavy materials - you should carefully monitor the quality of the metal.
6. Hook.
7. Steel cable with a diameter of 5 millimeters.
8. 2 keys with different parameters in the shape of an asterisk.

Step-by-step construction instructions

The process of assembling and installing a homemade garage crane does not look complicated:

• steel corners must be installed on parallel walls;
• fasten the steel plate to them using M8 bolts;
• fix the “worm” gearbox on the plate;
• install a larger key on the drive shaft;
• drill a hole in a pre-designated place, insert a chain into it and close it into a ring;
• fix a smaller key on the output shaft of the gearbox;
• drill 2 more holes in the plate;
• pass the second chain through the holes, where one end is on a small key, and a hook is installed on the second.

Installing a faucet yourself has a number of important advantages. For example, the cost of a homemade mechanism is almost two times lower than a purchased one.

How to use

The telescopic boom of the mechanism can be installed in several positions. The goose is maneuverable and can be controlled by 1 person. The equipment lifts quite heavy loads due to the installed jack; no additional accessories or devices for moving heavy loads are needed.

In order to raise the car engine, you need to open the hood and roll up the crane. It is installed so that the “legs” are placed under the machine, and the chain with the hook hangs over the engine.

The engine has eyes, cables are hooked onto them, and a chain with a hook is connected to them. Having installed the pry bar, pump the jack. He raises the boom, and the engine goes up with it.

Machine structure

The operating principle of a crane is based on the physics of simple mechanisms. The simplest version of the crane is a stick placed on a fulcrum in such a way that the free ends have different lengths. Now if you hang a load on a short lever, it will take less effort to lift it. The most common design is one that uses, in addition to levers, a system of blocks.

A do-it-yourself crane is an indisputable assistant in small-scale construction. When constructing a private house, the use of bulky industrial cranes is not required. The height of the houses rarely exceeds 2 floors, and the weight of the lifted load is 200 kilograms.

Crane diagram

Although there are many variations of lifting mechanisms, a classic crane consists of the following parts:

An arrow with a block attached to its end. Depending on its length, the height to which the load can be lifted is determined. Platform. The boom and counterweight are attached to it

It is the main part of the crane and is subject to significant loads. Therefore, when manufacturing the platform, it is important to pay special attention to its strength. Counterweight. Serves to stabilize the crane Determines the maximum weight of the load that the crane can lift

Stackable counterweight options are available to provide maximum stability. A guy wire connecting the boom and the counterweight. Allows you to adjust the tilt of the boom and move the load in both vertical and horizontal planes. Winch with cable. It is the lifting mechanism itself. The power of the winch determines how much weight the crane can lift. Stand with a rotating mechanism. It is necessary to turn the crane to the sides. The support cross, which is the base of the crane. Sets the stability of the entire structure. When manufacturing it, you should also pay attention to its strength.

Necessary materials

The tap is made from a profile 7 m long. It is best to use a material whose wall thickness is 7 mm. The mechanism must be durable, so you should choose a profile with a cross section of 80x80 mm.

To make a lifting device, you will also need several pipes. Suitable products are 700 mm, the cross-section of which ranges from 76 to 99 mm.

To build a crane you will need a jack, you can take it from a VAZ. It is best to use a device that is designed to lift loads weighing up to 5 tons. To construct the mechanism, 4 plates with a thickness of 8 mm are required.

To assemble a crane yourself, you need to have the following set of tools:

• drill;
• inverter for welding;
• spanners;
• Bulgarian

Assembling the mechanism is not complicated, so it can be easily done on your own. A gantry crane or any other device can be painted after assembly.

How to remove the engine from a car?

At home, there is usually no professional lifting equipment, so you will have to rent it or make it yourself.

Do-it-yourself goose for removing the engine

This is a simple mechanism that resembles a gooseneck. It makes it possible to move the engine away from the engine compartment. It may have a rotating design that allows you to remove the engine without moving the machine.

The heavy internal combustion engine is simply transferred to a workbench located next to the car. In fact, it is a universal garage crane. The rack rests on long “legs” located under the engine compartment to prevent it from tipping over. A cable and a winch are used for lifting.

The gander is used both in garage conditions and in small services.

DIY engine removal lift

As a rule, this is a rolling crane, the lower part of which is placed under the front bumper. A smooth platform is required; on uneven ground, removing the engine using such a device is problematic. The lift operates using hydraulics or a tensioning mechanism like a winch. The device is simple: a stand with rolling supports, and a movable boom on which the motor is suspended. You can make a lift with your own hands from a channel or a square professional. pipes.

If there are strong wheels on supporting legs, you can quickly roll out the lift with the motor and move it to the repair area.

Do-it-yourself winch for removing the engine

Applicable if the car is being repaired in a solid stone garage. The most inexpensive tool that can be used to remove an engine. A chain or cable is used to pull it out.

There are two design options:

Without removing the gearbox

In short, it is quite possible to remove the engine from your “nine” without removing the gearbox. To do this you will have to follow these steps:

• Place bricks or other reliable supports under the gearbox;
• Unscrew the left crab, move the stretcher aside;
• Remove the generator, crankshaft pulley, and camshaft gear from the engine;
• The pump, tensioner pin, distributor, and exhaust pipe are also dismantled;
• If a major overhaul is planned, then you can also remove the head;
• Then the engine mount is removed;
• The motor is moved from the box and lowered to the floor. To remove the engine, the front part is raised higher using a jack and the volume is removed;
• Or you can pull it out through the top using a winch.

In practice, all experts recommend dismantling the engine along with the gearbox. Especially if you plan to replace the engine or increase the power of the standard engine. In this situation, the box itself is often changed so that it can clearly interact with the new motor.

How to remove the engine from a car in the garage without resorting to the help of a car service

In fact, this is not such a complicated procedure as it might seem at first glance. The main task is to select tools for removing the motor.

Important! The engine weighs several hundred kilograms. Falling it can not only cause property damage, but also lead to serious injuries. Before lifting the engine from the engine compartment, the following procedures must be carried out:

Before lifting the engine from the engine compartment, it is necessary to carry out the following procedures:

1. Drain all technical fluids: oil, power steering fluid, brake fluid.
2. Free the cooling system from antifreeze.
3. Drain the gearbox (except when you remove the engine without removing the gearbox).
4. Disconnect all hoses and pipes of the fuel, brake, lubrication and cooling systems.
5. If possible, remove attachments: air conditioning compressor, generator, etc.
6. Disconnect electrical cables, engine control unit, injector control cables, high-voltage ignition coil wires.
7. Remove the connectors from all motor sensors. It is recommended to make a list (“based on” the maintenance and repair instructions), this will help you not to miss a hidden connector.
8. In most cases, you will need to remove the hood cover.

If you plan to remove the engine without the transmission, you need to unscrew all the tightening bolts and make sure that after removal the gearbox will not fall under the car. That is, you need to take care of temporarily securing the unit.
