Lifting devices were invented in Ancient Greece for carrying heavy objects. The machines that are now used on the construction site are more technologically advanced. Construction (tower) cranes are one of the largest devices of this type. They were first used in 1954. Since then, their structure affects their multifunctionality. Therefore, it is useful to know about them.
Types of construction cranes and structural elements
The most popular types of cranes are construction cranes. They can be self-propelled or tower. Wheeled (self-propelled) models allow you to move inside or outside the construction site. They are usable. On the other hand, Liebherr tower models guarantee large overhangs, load capacity and the height to which the total load can be lifted. In addition, their work is inexpensive, although it is performed intermittently.
The lifting device of the Liebherr crane consists of a boom, a tower, a counterweight, a rotary platform and a winch. His column is made in the form of a multi-element truss tower. In addition, it consists of an arrow with a so-called leash, swing or cantilever arrow. you can Buy Liebherr tower crane or rent it, but with long and complex construction works, the first option will be more economically advantageous. Liebherr tower cranes can be purchased throughout Ukraine from VIRAKRAN.
What is the use of construction cranes?
Construction cranes are widely used in various types of work.
These devices can be successfully used to transport heavy elements up to 80 tons. The load capacity and operating range of the device make the Liebherr crane one of the best technical tools used in construction. In addition, it will work well with restrictions when moving around the area, because it is stationary equipment. Therefore, it is recommended for the construction of large objects, for example, skyscrapers or hotels.
Also, it will work well when building various devices, disassembling, demolishing or moving equipment. This is a good replacement for a truck or crawler crane.
Tower crane installation
Installation of the construction crane should begin with the placement of the first element of the tower structure. For this, you need to prepare the basis in advance. After erecting a special anchor, the construction team fills it with concrete. After waiting for about 14 days, you can start assembly. Farm elements are fastened with bolts. A truck crane will help with installation. Responsible for raising the other parts of the tower. Then specialists connect them accordingly. In addition to the parts, the size of which varies from 3 to 12 m, there is also a tower crane driver's cabin and a rotary table. Then the counter-bevel is mounted. This is a horizontal part of the structure with a winch. It consists of a steel hook-cable. Then the arrow is attached.
Work at height ends with the placement of appropriate loads on the boom. In order to start work, it must be tested beforehand. You will also need the consent of the Technical Inspection Department.
