Modern houses are built higher, and concrete blocks It does not become easier. Therefore, if you think well, you can build a small lifting crane with your own hands. The carrying capacity is not large, the order of two hundred kilograms, although, most likely, it can raise more weight, but it is not desirable to overload it. This design It turns out completely collapsible, its components are obtained by weight of approximately 20-30 kilograms, so collecting such a crane alone will not be particular problems. In addition, this design is transported is also easily, for this I have quite used the body of a Chinese pickup.

Recall that earlier we have already published an article about homemade crane-baby, who are interested in looking.

Lifting crane device

The cargo winch of my design is a worm reducer on electric drive In 600 W, well, the booleholder is a hand-held drive, organized on the same gearbox. Remote supports with screw stops are borrowed from construction supports. The drums for winches managed to pull out of the rotors from electric enginesSepared suitable in size.

Based on the mobile platform, the four wheels taken from the conveyor are provided, thanks to them, the crane without any problems can be moved from one place to another only if you remove the crane removal supports. Such an operation on the removal and installation of remote supports takes about five minutes. Therefore, the crane is pretty mobile. But there is not a big drawback, to move the crane, it is necessary to lower the boom to zero, otherwise the crane becomes impossible, as its equilibrium is disturbed.

The arrow itself has a length of 5 meters, the pipe picked up O75 mm, and at the base of the boom itself lies the profile of the square shape made of two corners. Also provided a portal to raise the boom, as well as the rotation node made from the hub from the truck. As a counterweight, the bed is taken from the non-functioning machine along with the fourth tracks from the tracked mechanism. The brake in the winch is not provided in this case, because it is not necessary. The brake in the turn itself is also absent, due to the fact that the speeds are very small, and, therefore, there is practically no inertia.

The minimum metal thickness used in my crane is about 3 mm, as a remote support and the base, the generally used is a rectangular tube having dimensions of 85 * 50 and 85 * 55 - this is a kind of remains of the technique of agricultural purposes. The base of the tower is made from the ranger 200. In the hook cage, a powerful bearing is inserted, therefore, the hook is able to rotate regardless of the polyspaster, to exclude the overlap or the twist of the cable itself.

Stubborn screws 400 mm long, resulting in a crane can be installed on very uneven surfaces.

There is one small defects associated with wheels. The thing is that the wheels used in this case when moving along a loose soil simply come into it in it, according to a solid rammed surface - everything is fine. This crane is considered one-time, that is, after execution necessary work It dismantled on scrap metal or to shelter until the next application. That is why such a design has a minor carrying capacity, not strongly outstanding strength.

Making time on such a crane will need about three days, taking into account the preparation of all necessary components. In this case, the gearboxes turned out from the fact that the gear ratios of 1/30 and 1/35 have such gear ratios of 1/30 and 1/35. , output parameters on the shaft 600 W, the capacity of the condenser 80 μF. All installations without taking into account counterbalances weigh up to 250 kg, the cost of such a design is 4000 rubles. Mostly the components used are borrowed from other equipment, new here only cables and bearings.

A similar crane without problems raises one and a half hundred kilograms of cargo, more, so far, not yet moved to home.

The main knots of the lifting crane photo

Many people believe that to build a house of 6 meter bar alone - the task of the discharge of fiction. Nevertheless, it is quite realistic, but at the same time will have to use the helper crane, which is quite realistic to build yourself.

Insofar as wooden bar Pretty cumbersome and heavy, it will be quite difficult to raise it. With the help of a crane, in turn, the bar can be put into place of cutting, as well as with the help of its functions, you can quite successfully lift the sawn timing on the base of the house.

For the frame of the homemade crane, any kind of metal scrap is suitable. At the same time, it can be made from ordinary corners of 63x63x5 millimeters.

As an arrow, a five-meter tube with a diameter of 50 millimeters was used, also, the feature of the structure implies that in the future an arrow may be lengthened by several meters. A similar design of metal corners of 30x30x3 is enhanced.

The maximum weight rising by the crane is 150 kilograms. However, the peculiarity of the design of this crane allows you to raise loads weighing half-one, but for this you will have to increase the number of multiplicity of polyspers.

The principle of the work of the polyspaster is similar to the features of the gearbox: to achieve greater power, it is necessary to provide a corresponding rope length, which, accordingly, need much more. As a result, the speed of lifting the load will slow down, but the crane will be able to raise much more.

One of the main characteristics of the gearbox is the gear ratio, the polyspaster, in turn, should have multiplicity - the ratio of the number of "rings" on the cable with running away from the drum. Based on this, in the case when 5 turns are wound on the homemade crane, the polyspaster is five times. In other words, the force applied to the rise of a 100-kilogram cargo to lift the half-removal cargo.

What is the feature of the self-made lifting mechanism?

It is worth noting that the manufacture of all nodes and mechanisms of the self-made crane-assistant is the process of time consuming and tedious, requiring great time costs. Thus, to make all the components of the crane, you will need at least a week, and to build a finished device and its calibration will take another two or three days. A six-time polyaste was used as a rotation drive, the boom lifting drive, in turn, is represented by a two-time mechanical polyspaster.

Specifically, in this device, the swivel platform is made of two tablesheb, and the crane itself was assembled from undergraduated materials, so it is not surprising that the axis is represented by 30 mm. Bolt made of steel not possessing high strength. It is determined by such a decision that high-strength steel is practically not amenable to welding: when the strength is exceeded, such a bolt is immediately bursting, it is impossible to stretch it, nor bend it. The nodes of the self-made crane are desirable to lubricate with a small amount of litol. To reduce the mass of the counterweight, 2-meter support legs are installed in the crane.

When making nodes in the manufacture of this device, it is necessary to take into account that with an average radius of the part that is responsible for the rotation, as well as the distance to the counterweight with the specified mass, the tensile load will act on the main bolt (which will naturally be much larger). Before starting the crane, it is necessary to carefully check the stability indicators.

Blocks for the lifting mechanism can be built of two large and one small washers. Such blocks will be stable. It is extremely important that the cable has the necessary flexibility, or the blocks themselves had the corresponding rope diameter, because when lifting the boom without load, the rope can fly out of the block, which will be very unpleasant.

A thick cord was used in 15 mm in a diameter of 15 mm. It is planned that in case of elongation, a flexible, 5 mm will be installed on the crane. Cable with a workload of 150, as well as a bursting of 850 kg. A similar crane allows almost alone to build a house from a log house, and also to do huge number other construction work.

Today we will tell you how to build a console crane with your own hands. But at first a few words about what a similar design is different. So, cantilever cranes are used to raise moderate goods and are ideal for maintenance. construction sites. Moreover, they are used in other areas of industry - mechanical engineering, shops mechanical processing etc. Such wide spectrum Operation is explained by the possibility of work in the clock conditions, that is, in conditions of limited space.

Types of cantilever crane

There are two types of similar cranes.

Mobile structures consist of a frame based on two wheels and moving according to a special guide. The console itself is attached to the frame.

Stationary structures are attached on walls or special collens. It is characteristic that the colon can be installed on the base of the building. At the same time, the cranes are on one and two shoulders (depending on the type of support), and also have a different lifting capacity.

The described project is non-standard, but for its incarnation you will need only two assistants. The procedure begins with the preparation of the project.

Attention! All elements are fitted under the gas cutter CNC, since it is the cheapest option.

Technical task

Installation, loading / unloading for the efforts of four people.

Lifting height of 5 meters.

Sememeter console.

Load capacity - from 0.6 tons.

Installation without the use of special equipment.

Project preparation

The faucet will rely on three legs from the "twentieth" of a heap, fixed by flanges from 1,4-centimeter steel and M-16 bolts. A tube with thick walls is used as a shaft. Feet are equipped with additional struts.

Drawing

Use autocades to create a drawing, but round all sizes. Finished files from the program are immediately on CNC.

Welding

For welding all items you will need yourself welding machine, current force in 220a and five electrodes. When setting, use the mounting level. All this will require a maximum of one day.

Build construction

For convenience, cut down the legs, hold the assembly lying (it will take about a few hours). To raise the crane you will need a truck, cable and beam. One end of the cable to secure to the truck, the other to the crane. With the help of a truck pull the cable through the beam, while the design does not stand on your feet.

Sometimes when working under the hoods of cars, there is a need to promote additional mechanisms that can help pull out or hang the engine, while leaving in the pit under the machine there is enough space to access all parts of the car. Ideally, such a device that affects the repair of cars should:

• do not clutch the place in the garage;
• understand the components of the elements;
• be independent of the ceiling stationary ry-bolt.

It is such a mechanism and is a personally made crane-beam.

Video for the manufacture of crane-beam do it yourself:

Construction crane-beam for garage do-it-yourself

1. As a result of the execution of all the actions described below, a crane-beam will be built, which will look in the collected state like this:

2. In the disassembled state, this tool for the garage will have this kind:

The height of such a crane beam will be 250 cm, width - 415 cm. The base of the racks will have a size of 120 cm. All sizes are designed to work with passenger cars. If you need a crane-beam to work with more massive cars, then it is better to strengthen the design, making A-shaped vertical racks and additionally use kinks for the rod supports; The material used will have to have big sizesthan those that are given.

3. As materials for crane-beam, we will use:

• a pipe with a diameter of 10 cm, which will serve as a transverse one-dimensional rod;
• pipes with a diameter of 11 cm, which will perform the role of the rod support;
• bolts M: 16 for attaching to the supports of the rod;
• trumpet square profile 10x10 cm used as a rack;
• 10x10 cm corner for base and bevels;
• rollers under the cable (you can use rollers from the drive of the elevator doors).

4. Fastening the rollers occurs to a 5 cm strip, which is welded to the place of connection of the rod with supports.

5. To ensure the mobility of the tool to the racks, rollers taken from containers used in warehouses are welded.

In folding form, this subject occupies quite a few garage space.

6. The labeling mechanism is constructed from the manual worm winch g / n 800 kg having steel rope, by welding it to the vertical rack.

Often men spend free time In garages and domestic workshops, enthusiastically engaged in technical creativity. Other, having mastered independently working specialties to professionalism. Your hobby work money for family. But the technical creativity is sometimes impossible without severe physical labor, it is even unbearable. As one self-catering said: "Technical Creativity is the case for the soul in the sweat of your face."

In cases associated with dragging heavy manual equipment on a workshop, a telescopic console is useful. For welding works On cargo hook console, you can fix the welding machine. With authoritable-weight grinding machine. When making a joinery - a professional milling mill or the same grinder can be suspended.

The console telescopy will allow you to adjust it to the desired length and greatly facilitate labor costs. main idea Construction is to use rectangular pipes Other sections inserted into the friend in friend and to which support rollers and screw clamps are attached.

The drawing draws two main designs of the consoles - from bonuses and on the cable delay. Also, the bump can also be located on top if the height of the garage will allow.

The set for the garage consists of three assembly units - the first knee - the console from the pipe with a cross section of 80x60 mm, the second (average) link - from the pipe with a cross section of 60x40 mm and the third (final) link - from the pipe with a cross section of 40x25 mm.

The supporting rollers are located outside at the ends of all units, and the support wheels in the inner ends of the pipes. Over the supporting rollers on top of each pipe installed screw clamps for fixing the departure of the telescope arrows. Also there are welded maximum departure limiters: hook, cantole mounting hinges to the wall.

The minimum height from the floor level is 1900 - 2000 mm. Maximum length - 4500 mm.

To eliminate uncontrollable turning, the instrument with the tool can be replaced by the axis bolts with M20 nuts, whose tightening is created "insurmountable" friction of resistance in hinges.

Work in the garage or workshop equipped with dusty, it seems like this: the tool hangs on the hook next to the master. The wizard using suspended equipment, as necessary, lengthens or shorten the arrows departure.

There is another option to use a similar "telescope" (only lightweight) on the garden - to hold the watering hose over the beds and the ease of movement on plantations with a sprayer.
