Sometimes the construction of a house is not carried out correctly, for example, the technology was violated or low-quality materials were used. As a result, the floors began to rot, mold, fungus, an unpleasant smell of dampness began to appear, and the inhabitants became allergic. As a result, it became necessary to raise the house. There are many ways to do this. The main device for this is a jack for lifting the house. The main advantage of the device over other lifting products is mobility.
There are four types of devices:
- Rack.
- Screw.
- Hydraulic.
- Wedge.
Rack jacks
The name "rack jack for lifting" at home speaks of the main element of the device - a gear rack driven by rotation of the handle through a gear reducer. A distinctive feature of such structures is a large lifting height, positioning accuracy, reliability and simplicity. The load rises smoothly and is clearly fixed at the desired point, while the minimum effort is expended.
Hydraulic jacks
This is the most popular type of jack used not only inindustry, but also in everyday life. With its help, the load is easily lifted and fixed at a given height. Its work is based on the displacement and lifting of the piston with a special liquid to the desired height. The main components of hydraulic jacks:
- body;
- lifting arm;
- support;
- hydraulic pump.
A distinctive feature of hydraulic jacks is a closed system that protects against dust, moisture and low temperatures. The guide for the rod is the body of the mechanism. The rise is carried out due to the pendulum movement of the lever, the descent - by opening the valve built into the body. Thanks to its small dimensions, it is easy to transport by car and even carry the hydraulic jack by hand. The price depends on its type (rolling; hydraulic telescopic or bottle; hydraulic horizontal) and load capacity. It is used when carrying out various types of repair work.
Screw jacks
These tools are the simplest universal device for lifting loads of different weights to a height of up to one meter. The main element of the device is a screw, with which you can smoothly lift the house to the desired height. It can be rotated manually or with the help of a drive that allows you to adjust the lifting speed, if necessary, you can stop. A screw jack for lifting a house has a number of advantages over other types:
- large load capacity;
-compact size;
- light weight;
- unpretentiousness in operation: it can work with heavy pollution, with large temperature differences;
- small operating costs.
This is the most convenient jack for lifting a house, with which you can solve a wide range of tasks. Designed for intensive use.
Wedge jacks
Wedge tools are compact yet powerful devices with high load capacity. They are completely mechanical, so they do not need an additional supply of hydraulics, electricity or compressed air. This affects the reliability and durability of the structure. They can accurately check equipment on foundations and widen narrow openings.
