DIY crane

A do-it-yourself crane is always useful in the household for anyone who has a summer residence, or for those who live in a private house. It will be especially needed for those owners who are not afraid of various independent construction and repair work. Renting such equipment, and even more so buying it, will cost a considerable amount. And to make a crane with your own hands, in fact, is quite simple - you will learn about this in this article. Try step by step to understand the proposed instructions, performing all the work, and you will get a great tool for domestic use.

For further work, you will need the following materials:

  1. Worm gear (electric drive must be 600 watts).
  2. Building supports.
  3. Minor materials and tools for construction and repair.

Working process

Most of the necessary and useful tools can be made on their own, thereby saving the family budget well. In general, such a structure is assembled very simply and as quickly as possible. The algorithm described below will help even an inexperienced master. The main thing is to pick up for the future construction all the necessary parts and working tools.

Important! Ultimately, the resulting design will have a weight of about 250-300 kg. At the same time, it will be quite compact. A self-made crane will have a not very high carrying capacity (approximately 200 kg), however, this will be more than enough for most home construction or repair work.


Let's move on to the algorithm for making a mini-crane with our own hands:

  • There will be 2 bearings in our mechanism. In the upper part between the housing and the base will be a thrust bearing. Below is a plain radial bearing. Under the lower bearing, the inner diameter of the housing, as well as the outer diameter of the base, are calculated.

Important! Both one and the other part must fit tightly into the bearing. Thus, both parts are connected.

  • In order to more reliably fix the radial bearing, a nut is screwed on the bottom of the housing, the thickness of the threaded and retaining parts of which must be at least 3 mm.
  • Next, this assembly is attached to the platform with a bolt that will attract the base to the platform. So you get the following design: the platform with the base will be stationary, and the body with the nut will rotate.

Important! To tighten the bolt that will be attached to the base of the platform, you will need a ring wrench with an extension cord, as well as two washers - a grover and a flat one.

  • It's time to move on to making a mini-crane stand with your own hands. Its height should be up to your waist. In order to make it, they stock up a piece of pipe and 4 pieces of a channel. You can evenly trim the end of the pipe using a car clamp and tightening it on it, then cut the even circle with a grinder.
  • Next, the platform of the rotary mechanism is welded to the cut end, which must be ordered based on the dimensions of the pipe you have chosen.
  • Next, proceed to the manufacture of legs. They are welded in such a way that the rack itself does not collapse.
  • Now you can move on to hanging the pipe with an already welded platform. The rope is passed into the hole in the center of the platform of the rotary mechanism, and the legs are substituted obliquely to the pipe. Thus, the pipe should hang evenly, and the legs should rest on it from all four sides.
  • After finding the balance of the crane with your own hands, the angles of the channels abutting the pipe are outlined by eye and cut with a grinder.
  • Next, proceed to the manufacture of a supporting cross and attaching it to the legs with nuts. It is usually made from various rigid profiles.
  • After that, they move to the platform of the crane, where there will be a counterweight, as well as an arrow and a winch. The platform is attached to the housing of the rotary mechanism with four bolts.

Important! As a platform, you can use a 1.5-meter I-beam, the width of which will be approximately 18 cm.

  • Let's move on to the counterweight block - it is usually made from channel pieces, but other options are also acceptable. Ultimately, the main thing is the quality of the resulting cargo container.
  • A winch is usually installed with a capacity of 0.5 tons, with a brake.
  • It remains to make an arrow for the crane with your own hands. It is always made of timber, mounts with a shaft and a tip with a pulley.
  • The mounting case is made from a piece of a channel, and for a shaft, for example, a piece of the rotor shaft from some old engine is suitable. After that, it is bent in a vice, and two brackets are attached around it, after which it is fixed to the fastening case, which will later be inserted into the prepared bar.
  • Bearings are purchased for conventional bearings that will fit snugly onto the shaft. In the mounting case, a seat is cut out.
  • Bearings in the housing fasten.
  • The beam is attached to the channel with ties made of a metal strip, the thickness of which is about 3 millimeters.
  • A cable pulley is attached to the end of the boom.
  • Next, the arrow is collected, having previously strengthened it.
  • After that, they go on to assemble the entire crane platform with their own hands. A winch is installed on it, under the winch there is a block of counterweights, on the other hand, a boom lifting body with an arrow.

Important! The entire assembly should take place in a lying position, and after completion, the structure must be raised so that it is in a vertical position on some support.

  • The rotary mechanism is attached to the rack, after which the platform is mounted on it in such a way that the boom and counterweight are in balance.
  • The assembled crane platform is suspended and lifted so that it is possible to substitute a rack under it.
  • Raise the platform using a winch. To do this, its cable is passed through the block and hooked to the boom lifting housing located at the other end of the platform.
  • The platform is lifted using a winch.
  • Suspending it in this way, and substituting a stand under it, they catch the position where the counterweight balances the arrow.
  • In this position, four through holes are drilled and the platform is bolted to the stand.

The work can be considered completed!
