Fiber ropes – a new stage in the development of cranes

Ropes have been used for lifting and moving loads for many centuries. Even during the construction of the Egyptian pyramids, strong ropes were used to transport stone blocks. Since then, several thousand years have passed, not only the lifting mechanisms have changed, but also the ropes themselves. At first, ropes were woven from fibers of plant or animal origin, but now steel ropes are usually used in construction cranes. However, in the West, a number of companies are conducting research on the creation of fiber ropes for cranes, and they have achieved some success.

Self-lifting inside a building is an affordable engineering solution for tall buildings and skyscrapers under construction. First, it is economical, and second, it is safe! This example of a crane is located at a height of 300 m

Load drop protection on Liebherr cranes

   

  All modern Liebherr cranes have automatic load drop protection. The Danfoss frequency Converter is responsible for this work. In Danfos, a program developed by Liebherr specifically to protect the fall of cargo is installed.     

Liebherr 357 HC-L 24/12

The third-generation 357 HC-L 12/24 Litronic crane with a controlled lifting mechanism was first presented in 2013. The advantage of the model is that the boom of the 357 HC-L crane is set to a minimum position of 87°, which allows it to be used on the narrowest construction sites, for example, it is an excellent option for working with a large concentration of tower cranes in a limited space.

Liebherr 150 EC-B 8

The Liebherr 150 EC-B 8 is a tower crane with a slewing tower and a boom. Mounted on a monolithic foundation, support frame or running frame (rail track).

EC-B series tower cranes are economical to transport, quick and easy installation. The headless design gives an advantage when working together with other cranes and works near the airport. The maximum possible spacing of 60 m is the Liebherr 150 EC-B 8 is mounted on a support frame, on a monolithic foundation or on a running frame (on a rail). For the crane, towers 120 HC, 185 HC, 256 HC,  HC 290 are used.
