Sometimes the construction of a house is carried out incorrectly, for example, the technology was violated or poor-quality materials were used. As a result, the floors began to rot, mold, fungus, an unpleasant odor of dampness began to appear, and the inhabitants had an allergy. As a result, there was a need 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 and pinion.
- 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 the rotation of the handle through the gear gear.
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 jacks used not only in industry, but also in everyday life. With its help, the load is easily lifted and fixed at a given height. His work is based on the displacement and lifting of the piston with a special fluid to the desired height. The main components of hydraulic jacks:
- housing;
- lifting lever;
- 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 integrated in the housing. Due to its small size, it is easy to transport by car and even carry a hydraulic jack manually. 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 up to one meter of different mass. The main element of the device is a screw, with which you can smoothly perform the lifting of the house to the desired height. It can be rotated manually or with a drive that allows you to adjust the lifting speed, you can stop if necessary. A screw jack for lifting a house has a number of advantages over other types:
- big loading capacity;
- compact sizes;
- low weight;
- unpretentiousness in operation: it can work with severe pollution, with large temperature differences;
- low operating costs.
This is the most convenient jack for lifting the house, with which you can solve a wide range of problems. Designed for heavy use.
Wedges
Wedge tools are compact and powerful at the same time with high payloads. They are completely mechanical, therefore they do not need additional supply of hydraulics, electricity or compressed air. This affects the reliability and durability of the structure. With their help, you can accurately check the equipment on the foundations, as well as expand narrow openings.
