A crane is a device with which you can lift and move loads of different weights. The main characteristic of any crane is its load capacity, that is, the maximum weight that it can lift. These mechanisms differ both in scope and in design. Briefly consider the device of the main types of cranes.
Common to all of them is the presence of a
lifting mechanism, with the help of which the lifting and movement of goods occurs. By type, the crane can be rotary and non-rotary, mobile and stationary.
Swivel
They have an arrow that rests on a column (moving or fixed) or turntable. These devices can be installed on rail and rail. The latter are automobile, pneumatic and tracked. In addition, stationary slewing cranes (roof or wall) are used.
Fixed
A fixed crane is usually a span type design. In addition, wall-console mechanisms belong to this type. Overhead overhead overhead cranes are equipped with a hoisting device moving on rails. In this case, the rails are laid on top of the opposite walls of the building. The design of the wall includes a special farm, mounted on the wall of the building.
Main purpose
Cranes are most often used in enterprises. This is a very useful and sometimes irreplaceable technique. With its help, lift heavy loads to a height and move them from place to place. This is often necessary, for example, when installing block foundations and panel walls, during roofing and finishing works. In addition to construction sites, cranes are used in warehouses, for moving goods, in ports, at enterprises. Not a single crane or foundry can do without a bridge crane.
Application in private housing construction
Owing to their high cost, it is quite difficult for private owners to purchase even a small personal crane. Rent in this case can be a pretty good alternative. After all, usually at a private construction site a crane is not needed all the time, but for a one-time performance of one or more specific tasks. Sometimes owners of cottages and houses use home-made lifting devices.
These are fairly simple mechanisms, which, despite their relative primitiveness, do a good job of their tasks. Sometimes it can be a real home-made crane. Such devices usually have a sufficiently large carrying capacity (300-350 kg) and boom length (6-8 m). To make such a crane is quite difficult, but possible. The only thing in the manufacture must comply with certain safety standards and rules. The simplest such crane can consist of an arrow, supports, a counterweight and a lifting mechanism.
A crane is a very useful and functional device, without which it is impossible to do on construction sites, warehouses, enterprises and in all those places where work is carried out with heavy materials and objects. This technique can greatly facilitate the work and reduce the time of the work itself.
