how to calculate- Instruction + Video and Photo Crane well - how to calculate and do it yourself. The Russian village is distinguished by its incredible color and immersion in ancient times of villages, estates and peasants. One of the attractions is the well-crane, which has not lost its popularity, as it is convenient and quite functional. How to make a well-crane?

It's not difficult, just do some calculations, and the article will help you do it.

General information

The well crane is a kind of balance lever that has shoulders of different lengths.

At the longer end, a piece of chain, about 1 m long, and a pole are fixed, at the end of which there is a bucket for water, and at the other end a compensator. The balancer is installed on a rack next to the well, at a short distance from the edge.

The well, which has a crane with the construction, consists of the following elements:

Interesting! The permissible depth of a well with a crane is not more than 10 meters.

How to calculate a crane for a well


What the crane will look like is determined by depth and level water in it. To calculate, you will need to measure the depth of the well (h) from the surface of the earth to the bottom. When taking water, the bucket should in no case reach the bottom of the well, at least 30 cm.

The upper edge of the lever should be located along the axis of the well and have a height of about 150 cm so that no one would be injured when drawing water. In the general calculation of the length of the pole with the chain (L), you can use the following formula:

L = h + 150 cm.

If you denote the height of the rack h1, and the length of the large lever and its arm as l1, the length of the small arm is l2, and the distance from the rack to the center of the well is h2, then you can use more formulas for self-calculation.

H2 - this distance from the balancer post to the center of the well must be less than h by 70 cm. The height of the post h1 = h / 2 + 240 cm.

The length of the front part of the lever l1 = H-20 cm. The length of the short arm with load l1 = Н-80 cm, and the total length of the rocker arm is 2Н-100 cm.

If the depth of the well is 500 cm, and a regular bucket with a capacity of 10 liters is used to collect water. , the weight of the load that is attached to the short end of the crane will be approximately 12 to 14 kg. For a more precise definition of the load, you can go empirically.

First, you need to find a place for the well, and this must necessarily be a site that is far from outbuildings, a toilet and other possible sources of pollution. The ideal solution is accommodation 4-5 meters from the house. Any landings and other objects that may impede normal movement should be removed near the balancer arm.

What is required for work

In order to make a well-crane with your own hands, you will need materials such as:

  • Self-tapping screws.
  • Wooden bar.

  • Nuts.
  • Boards.
  • Chain.
  • Bearings.
  • Threaded rods.

  • Rope.

And in order to perform all the work, you will need the following tools and accessories, namely:

  • how to calculate- Instruction + Video and Photo Sandpaper.
  • Shovel and blade shovel.
  • Screwdriver.
  • Manual garden drill.

  • Wrench.
  • Jigsaw.

When all the tools and materials are ready, you can start.

Making a mine

Immediately I would like to note that a mine should be dug for a well in 1 day, therefore, most likely, you will have to find helpers. The optimal shape for a shaft is a circle.

But if you want, you can make it hexagonal or square. Be sure to outline the contour on the ground surface. A small hole of the same shape should be dug inside, and then it must be deepened to the required depth.

When digging, you will need to remove the earth masses, and this will be easy to do with a bucket or barrel, which will be tied with rope. Workers can climb and descend the rope ladder, but this will require anchorage to the surface.

Remember that when digging, you should from time to time free the mine room from accumulations of gases, as they can be hazardous to health. When everything is ready, free the mine from water, and then reinforce the bottom. Crushed stone or gravel should be poured on it so that the water undergoes primary filtration while still in the well.

The walls of the mine can be laid out in the form of a log frame. To do this, first lay out one frame on the bottom, which must be well aligned horizontally and vertically.

After that, the blockhouse begins to build up by laying new logs. To enhance the adhesive qualities, the frames made of logs are pressed and tapped with a wooden hammer.

To make a well-crane with your own hands, it is better to use a frame made of logs to the bottom with a lower pointed edge. It needs to be laid only in the finished pit and start removing the soil, first from the inside of the frame, and then around it. Further, under the weight of its weight, the structure itself will go down and cut through the ground with pointed edges.

As the structure sinks, the frame should be built up to the required size.

For seams to be sealed, they must be lubricated with clay. Use thick boards to prevent skewing. They should be nailed in the corners from the inside. All wood elements in the well shaft must be well planed and leveled from the inside.

This will make it possible to freely raise and lower a bucket or any other container for water.

Aboveground part

Above, around the mine, you need to make a box that will repeat its size and shape. For this, you can use boards and beams, as well as logs for felling. The above-ground part can be made from a screed or a ready-made concrete ring. It should be poured in advance between two layers of laid out formwork.

After that, be sure to make a roof for the box, it can be folding or removable. This will help prevent small debris, sediment and other objects from entering the water from the well.

How to make a support

It was not for nothing that we talked about how to calculate a well-crane, since this data will be useful for creating a support. It is a vertical, fixed stand. It can be made from a piece of pipe, a thick bar, a channel, etc.

You can determine the installation location using calculations. The length of the support beam can be determined from the depth of the well. The minimum allowable section is 5 * 10 cm. Before installation, the support (if it is made of a bar) should be treated with an antiseptic agent, as well as another impregnation that will protect against corrosion.

"Stepchildren" made of a metal pipe will help prevent decay.

They should be fixed on the opposite sides of the timber, and the ends should be left as long as possible, which will then be immersed in the ground. This will help insulate the timber from contact with the soil. Steel pipes should be attached to the base beam using mounting studs marked M10. The finished structure should be installed in a previously prepared pit, and the space around should be free, at least 20-25 cm.

Now the support must be carefully aligned vertically and hammered into the ground a little, and then filled with concrete mortar.

Level it up. The concrete will harden for about 15-21 days, and during this time, the trimming of the timber should be supported to fix it.

Installing the balancer

The boom of the well (lever) can be installed only after the concrete has hardened. For manufacturing, you can use a bar with a cross section of 5 * 5 cm. But do not forget that it should be pre-treated with a protective agent.

Install the balancer on the supporting column, but after checking the load capacity. The installation of the boom to the support is carried out through the hinge assembly. To do this, attach a pair of stainless steel corners using mounting pins in the amount of 4 pieces.

After that we hang a pole on the boom. To make a pole, you can use a duralumin tube, which will be covered with a film with a moisture-resistant effect.

The pole is fixed with a 1 meter long galvanized chain. The bucket should be attached to the long end of the pole. Thanks to the calculation of the crane well, it is known that a chain with a length of 0.5 meters is required. Attach a weight to the top of the bucket so that it can roll over when it comes into contact with water.

At the short end of the boom, attach a counterweight, which can be made of anything, using mounting studs.

The weight is selected exclusively based on the calculation results. Secure the load. If you make it movable, if necessary, you can adjust its strength of action. The fixing of the expansion joint to the short arm must be reliable, the balance bar must be free from sharp edges, as well as protruding fastening pins and burrs.

Safety Precautions

When installing the boom linkage, certain safety precautions must be followed. Each of the elements must be pre-inspected for cracks and damage both outside and inside. Before installing the balancer, check its strength after a test installation at a low height and hanging on the longer end of the test weight. When installing a weight that will weigh like a container with liquid, a chain and a pole, the elastic deformation should not be more than 10: from its length.

The pole with the chain sections attached to it should also be checked for strength.

To do this, one end of the chain should be well attached to a fixed support, and a load should be suspended at the other end, which will weigh exactly 2 times more than the container and water.


When the do-it-yourself crane well is ready, it becomes a landscape design element. For this reason, the decorative design should be such that your taste and other elements located in the summer cottage are taken into account. To decorate the support, dig a groove around it. It is necessary to pour humus into it and plant bindweed plants.

The best option would be to plant plants that are unpretentious to care for and have beautiful flowers. You can design all the components and design elements of the crane in the form of an interesting figure, character, bird or animal. You can consider interesting design ideas in the photo with a do-it-yourself crane well.

Advantages and disadvantages

The main disadvantage of this design is that you can get water only from a shallow depth. Ideally, if the location of the moisture layer is at a level of 5 to 6 meters.

If there is enough space on the site, you can make the crane longer than in the standard version, and get water from a depth of 8 to 10 meters, although in this case the strength of the structure will suffer. There are still difficulties with the manufacture of a sealed cover, and therefore there is a high probability that debris and sediments will still get into the well. There is a more reliable option - the arrangement of a well house, but this is already technically more difficult, and this is due to certain design features.

Among the advantages of such a well, the ease of drawing water should be emphasized, since almost no effort is needed. Using such a counterweight will shorten the water extraction time when comparing the model to a standard well.

In winter, the crane is not as susceptible to low temperatures. And one more indisputable advantage - the crane well will fit into absolutely any landscape design. If you want to decorate the structure, it will not be difficult and will not be expensive.
