The winch is an indispensable device, as in household, and in the garage. Lift a roll of roofing felt onto the roof, throw a couple of bags of cement into the second floor window of a private house under construction, pull the engine out of the hood, and drag the broken car itself into the garage... This is an incomplete list of tasks that can easily be done alone with its help.

Adaptations drum type for lifting or moving heavy objects, they differ in the way they transmit torque. From our school physics course we know how the shoulder works. Losing in speed or distance, we gain in strength. The phrase of Archimedes: “Give me a fulcrum, and I will turn the Earth upside down” precisely describes the principle of operation of the winch.

IMPORTANT! When working with such a device, the support points are the body and the place where the winch is attached. Both elements must be reliable.

A manual winch, with the help of an attached shoulder, increases human strength so much that one operator can move cars or lift weights of several hundred kilograms. With the same (from a mechanical point of view) principle of operation, these devices have various ways execution.

Manual drum winch - varieties

A hand winch with a drum is a classic of the genre. Except common element– the pulley on which the cable is wound, the devices have Various types drive.

A large, main gear is firmly attached to the drum. The entire load falls on it, and on the fastening. Therefore, the reliability of the elements must be at the proper level. In mesh with the main one, there is a small driving gear.

The ratio of the number of teeth is the value of the gear ratio. In other words, gain. The drive gear is integral with drive shaft. Because the we're talking about O hand tools– a handle for rotation is put on the shaft.

The length of the lever also affects the degree of reinforcement. The larger the handle shoulder, the less effort must be attached.

With the help of such devices, you can single-handedly lift several centners of cargo or move a car weighing 2-3 tons. At the same time, the rotation speed of the drum is quite high.

The design consists of two or more pairs of gears, each of which has a gain of tens of times. With sequential engagement, these coefficients add up, multiplying the force.

back side medals – proportional reduction in speed. Having such a winch, you can slowly vertically lift loads of more than a ton, but if you have to work with two bags of cement, the lifting time will stretch for tens of minutes.

A movable and simpler stationary crane beam in the garage with your own hands is quite doable if you have it welding machine and two days of free time. For a professional auto repair shop, it is easier to buy ready-made lifting equipment.

If the need for a crane is rare, then it is cheaper to make a simple and reliable lift yourself. Such a homemade crane can easily lift a weight of up to 800 kg, and this is quite enough for repair work in the garage.

In order to make a frame for a small beam crane in a standard garage with your own hands, you will need the following materials:

• I-beam (4 - 4.5 meters) - the required footage depends on the height of the garage;
• pipe (diameter 10-12 cm), length 2.4 meters - 2 pieces;
• one square pipe (10x10 cm);
• corners (10x10);
• manual hoist and hoist;
• bolts (M16) with nuts.

If you plan to build a mobile crane beam, then you need four more rollers and a hoist.

The procedure for making a crane frame with your own hands:

• We weld the legs of the crane - you need to weld the corners on both sides to the I-beam pipe;
• The location of the corner is at an angle of 45 degrees. The result is a kind of stiffening ribs that will firmly fix the stand, which bears the bulk of the weight of the load carried by the crane;
• We weld two triangles and spacers on each crane post.

• if the crane is a mobile beam, then on both sides from the bottom, on each stand, a roller must be welded horizontally - ordinary rollers for metal containers will do, furniture rollers will not withstand the weight;
• At the top, we fix a pipe as a crossbar along which the lifting mechanism will move;
• We weld an I-beam in the center of the pipe to secure the roller along which it will move. steel rope crane lifting mechanism.

• We weld a piece of square pipe on top of the I-beam (to give rigidity to the frame) - 40 cm. The pipe should protrude at least 20 cm on both sides. It turns out that side stand located in the middle of the crossbar stiffening pipe;
• V square pipe insert the transverse pipe of the frame crossbar;
• We drill through holes for fastening bolts on both sides of the square holder and in the crossbar pipe itself - we need rigid, reliable fixation on both sides of the vertical post.

The result is a U-shaped structure of the crane frame, which is installed on rigid legs with spacers, and a crossbar pipe is rigidly bolted to the top.

Installation of lifting mechanism - manual or automatic

To mechanically lift loads onto the frame, you need to install a manual hoist - a worm winch and a cable. How to attach the hoist to the frame:

• on the side of the rack we install a manual worm winch (load capacity 800 kg, no less);
• The steel cable moves along rollers.

This mechanism makes it easy to lift the engine or a car behind the hood on one side.

You can use the lifting mechanism and rollers from the elevator door as a drive. The rollers there are reliable and durable.

An electric lift drive can also be installed on the manufactured base. A 300 - 500 W motor will be quite enough for simple repair work in the garage.

Such cranes are often used for the repair and reconstruction of old wooden houses. The construction of a log house will go faster if the logs are laid using a mobile homemade crane. In this case, the width of the frame is the length of the logs.

You can also make a simpler lift for the engine, on one support, watch the video.

Homemade winch (telpher, hoist). How to make a lifting mechanism for a garage, workshop, construction site.
Many home craftsmen would like to have some kind of lifting mechanism, such as a hoist, hoist or winch, in their garage or workshop. Of course, you can buy them ready-made, but they are usually not very cheap - several thousand rubles. And they are not often on sale. Automotive rescue lever winches available in almost any store cannot be used for lifting loads. Because their stoppers are made using a ratcheting mechanism. But it only works well in one direction. It is easy to lift a load with such a winch. But lowering it smoothly is problematic. When independently manufacturing hoists or winches, the master is faced with the problem of where to get a powerful, reliable gearbox (with a gear ratio of at least 1:20 - 50) and always with a self-braking effect. As a rule, these are powerful worm gearboxes and they do not often fall into the hands of a master.

Meanwhile, almost anyone can make a homemade winch or hoist, and, as they say, from scrap materials. Threaded rods up to 2 meters long are available for sale. And it can serve as an excellent gearbox for a homemade lifting mechanism.

The design of such a winch is clear from the sketches. The principle of operation of the winch is simple. If you rotate the threaded rod itself, and the nut on this stud is not allowed to rotate, then the nut will move along the stud. The force during this movement is much greater than that required to rotate the pin (all screw jacks work on the same principle, the increase in force there reaches 20-30 times the magnitude).

The ends of the stud are fixed in bearings, which in turn are installed in supports. A stud nut is a rectangular metal plate to which regular nuts are welded. The plate prevents the nuts from turning. A cable is also attached to the plate. The cable is passed through one of the supports and thrown over the block. At the other end of the cable is a lifting hook or sling system (this depends on the purpose of the lifting winch).

The pin drive is easiest done manually. To do this, a pulley or gear is attached to one of its ends. (you can, for example, even use a bicycle). A strong cord or chain is thrown through a pulley or gear in an endless loop. If you pull on one side or the other of the cord, the pin will rotate and the nut will move along the pin. Accordingly, there will be a cable behind you, and the load will either fall or rise. The self-braking of the mechanism is absolute; no force on the nut will force the pin to rotate. Most likely, the whole thread will break off.

Of course, you can also make an electric drive using any reversible electric motor with a power of 200-500 W. It is convenient to use, for example, some inexpensive electric drill with rotation direction switch. Nowadays there are many such drills available for sale. The electric drive can be made either directly or through an additional pulley or flexible shaft.

Such a homemade winch can lift a weight of several hundred kilograms. In most cases this is sufficient for household needs. The length of the stud, or rather the ability to move the nut along it, determines the lifting height (in the simplest version of this homemade hoist). If you take a 2 meter long hairpin, then this height will be approximately 170-180 cm, which in the vast majority of cases is more than enough for a home workshop or garage. However, it is not difficult to increase the lifting height using simple techniques.

The support (base) for such a winch can be made from durable dry wooden beam or thick board. Although of course it is better to use metallic profile or channel. All connections are made by checking or using bolts. It all depends on the purpose and capabilities of the master. It is not difficult to organize the movement of this hoist under the ceiling. For example, using some kind of T-beam placed in the center of the workshop. And install the caliper itself on the beam so that it can rotate around its center. Then almost any point in the garage or workshop will be accessible. A similar result can, of course, be achieved with the help of various blocks, it would be possible to attach it to something. Of course, the floor beams of the building must also be designed for additional load.

Based on such homemade winches, you can make a homemade crane. This will require at least two of these winches. It is most convenient to place them in the crane boom. One of the winches will lift the boom itself (change its angle of inclination), and the second will lift the load itself. Of course, you shouldn’t forget about the counterweight.

The simplicity and accessibility of such a homemade winch opens up quite a wide scope for its use in a home workshop, garage or construction site.

Konstantin Timoshenko

A suspended hoist in a garage is used as a lifting device. The equipment helps to move heavy objects and make car repairs more convenient. Armed with the necessary components, you can assemble the hoist with your own hands.

A lifting hoist, also called a hoist, can be manual or electrically driven for automated use. According to technical characteristics, the equipment is a mechanism for lifting and moving various loads, including car parts.

The mobile trolley can be placed in any room, regardless of free space and ceiling height. Depending on the type of design, the load capacity can reach 10 tons. A standard hoist is capable of lifting loads to a height of up to 12 m. The structure consists of the following elements:

• chain hoist, consisting of several blocks connected to each other;
• cylindrical coaxial gearbox;
• disc braking system;
• output shaft;
• hanger with hook.

Where is it used?

The lifting device is used to move loads of various sizes and weights. These could be objects household appliances, metal constructions And car parts. IN production premises equipment is used to lift loads and place them on top shelves.

Manual hoist finds wide application during repair and construction work when there is a need to lift tools and heavy materials.

Varieties of hoist designs

There are several types of design that differ in installation method, design features, control option and others. technical characteristics. Choosing suitable option equipment for the garage, it is necessary to take into account the individual needs and parameters of the room.

Manually driven

Hand hoists are used to lift objects to low heights. Equipment load capacity indicator with manual drive varies from 1 to 8 tons. Traction force at lifting mechanism is 30-65 kgf, which provides a speed of 0.3 to 0.1 m/min. The weight of the structure depends on the material and additional components and ranges from 50 to 400 kg.

Gear manual

Chain hoists with a gear mechanism are used to perform installation work within a garage or in an open space. The equipment is controlled at the load securing point. Gear models are equipped with a hanging hook and are easy to install and operate. Design features gear hoists allow them to be used as independent equipment or as a lifting element for cranes.

Lever

The manually operated lever hoist is equipped with a hanging hook and can be secured to support beams or wire rope. The manual operating principle ensures independence from the presence of electricity. The design provides a locking mechanism for fixing objects in a suspended state.

Worm

Worm hoists, by analogy with other varieties, are used to lift and lower loads. When picking additional elements worm hoists can move objects along an I-beam monorail track. You can hang a stationary hoist on a hook manually or make a complete version connected to a mobile trolley.

How to make a homemade manual hoist: step-by-step instructions

When making a manual hoist yourself, just follow step by step instructions. Equipment can be crafted by following these steps:

1. Weld the faucet legs to the I-pipe.
2. Position metal corners at 45 degrees to create stiffening ribs that secure the rack. The bulk of the load being lifted falls on this rack, so for additional reliability, spacers need to be welded to it.
3. If the hoist is mobile, rollers must be welded on each stand.
4. Fix a pipe on the garage ceiling along which the lifting mechanism will move.
5. Weld an I-beam in the center of the pipe to secure the roller mechanism.
6. Insert the frame crossbar into the pipe.
7. Drill through holes on both sides of the holder and fix the lifting mechanism.

Tools and materials

To build a hoist, you must first prepare a set of tools and components. In particular, to create a hoist you will need:

• an I-beam with a length of about 4-4.5 m (the exact length depends on the height of the ceiling in the garage);
• square pipe with dimensions 10x10 cm, 2 pipes with a diameter of 10-12 cm and a length of 2.5 m;
• Bulgarian;
• metal corners 10x10 cm;
• M16 bolts with nuts;
• lifting mechanism.

If you plan to install a mobile hoist, you will additionally need to use 4 rollers. The components are used to move the trolley.

Mounting nodes

One of important stages construction of a mobile structure is the installation of components. First, you need to drill holes in the racks through which a rod with threads at the ends will be pulled. Washers are attached to the base of the rod and nuts are screwed on to limit the divergence of the posts. Then a chain is fixed on each side in the middle of the pole.

In order for the winch to move freely, there should be some slack in the chain. A block with a cable is installed on the chain, running along the middle pillar and fixed from the bottom.

Activation and performance testing

Before each start-up and operation of the hoist, it is recommended to check the functionality of the main elements. The following components are subject to inspection:

1. Chain. Since the chain is responsible for holding the object at a height, it is important to check the load capacity. Periodic maintenance involves cleaning the chain from dirt and lubricating it with grease or similar materials.

A homemade manual hoist is a good replacement for industrial designs, because it is no less effective. So it’s worth getting such a helper in your household, and we will help you do it and tell you about this device.

How does a manually driven hoist work?

A hoist is a suspended lifting device. It can be manual or electric; the second option is, of course, more common. A hoist, in general, is a special mechanism for lifting or lowering various loads, as well as for moving them. The lifting capacity can be up to 10 tons, and objects can be lifted to a height of up to 12 m - you must admit, not bad for a manually driven mechanism.

Based on these indicators, this device can be used to move various goods heavy weight, these can be household appliances - gas stoves or refrigerators, freezers or washing machines etc. Trade workers often use them to put goods on shelves. You cannot do without manual hoists during construction or repair work, where you often have to lift Construction Materials or tools.

An ordinary manual chain hoist has the following main elements: a chain hoist, consisting of movable and fixed blocks connected to each other; two-stage cylindrical coaxial gearbox, which has a manual mechanical drive; output shaft; specialized disc brake; additional system load braking; block pendant with hook. The operating principle is based on traction and load chain systems that have round links. The main types of manual hoists: gear and lever.

Gear manual hoists – is their popularity justified?

The main advantage of this type of hoists is considered to be simplicity of design and reliability. You can’t do without them in many industries: neither in the construction, nor in the mining industry, nor in agriculture, nor at fuel and energy enterprises and others. This device can be used not only indoors, but also outdoors. outdoors, even if there are no power sources. Moreover, such hoists are not only safe to use, but also unpretentious to use and have a durable mechanism.

The gear type of hoists is suitable for working with large loads weighing from 0.5 to 10 tons, and they can be freely lifted to a height of up to 12 m. A special load chain with a hook is designed for such a load, and the available additional drive chain will ensure not only good movement, but also easy movement of loads. You need to control the operation of such a hoist while standing on the ground. The action begins with the drive chain, this device is a stationary mechanism, and its purpose is to raise or lower loads from high shelves.

Monorails are installed indoors to move goods using hoists. Such stationary devices are usually used when there is no need to constantly move and lift loads. They are not designed for a large amount of work, and the movement speed is very low, this must be taken into account when choosing of this instrument. But at the same time, if you need to lift a fragile product or object, then these are the most successful hoists. Now we need to talk about the competitive model.

Lever hoist – advantageous physics of load capacity

This type of hoist is necessary for working with small loads, the weight of which is no more than 5 tons, and it can be raised to a height equal to the height of a person. It all depends on constructive solution. Raising, lowering and moving is carried out using a lever built into the body. The hoist is controlled by an operator located near the device. Such models are good for tensioning cables and lifting loads. Since they are not suitable for a large volume of work, utility services find use for them.

They are necessary when you need to tension cables or install pipes at the bottom of trenches, as well as for installing hatches. With their help, foresters pull out stumps, and industrialists place heavy equipment in the workshops. Often their purpose is to lift a load in order to work with it, like this. It can be different renovation work, for example, in car repair shops. To make working with lever hoists easier, they are additionally equipped with special trolleys.

Worm worm hoists - a compact strongman

In addition to these main types of manual hoists, there are also others. IN Lately Worm worm hoists are often used. To operate, they are hung stationary or a mobile “cat” is used. This is convenient for moving loads horizontally; such hoists can move along I-beams. There are a lot of models of this type of device. They are used for lifting or holding loads in a raised position; they are also suitable for moving. Everything happens along a special suspended track made of I-beam profile.

Their advantage is that work can be performed in small spaces, and the distance between beams and loads can be insignificant. Such hoists can also be used for work outdoors.

They have some features, for example, a rotating casing (and the design can rotate all 360 degrees) allows you to control work from anywhere, that is, you can raise and lower the load in any position. This creates additional safety; during operation, the operator can be located on the side of the hoists and also from the load itself. Also this type The hoists are distinguished by their reliability, wear resistance and low-heating brake. All this makes them quiet and comfortable. And thanks to the low building height, you can work with this equipment in confined spaces in vertical positions.

Homemade manual hoist - a free household assistant

Often you have to carry out repair work at home, and you need to lift tools and materials. If you buy a manual hoist, it is expensive, and often you don’t have time. In this case, you can do it yourself.
