154HC Mast Section According to the need to explain, how the tower crane lifting weight changes with the range
the wide application of tower crane, more people are concerned about the technical knowledge of tower crane Found that many friends want to understand the performance of the tower crane, tower crane construction company http://www.fx68.net , according to the need to explain how the weight of the tower crane is changing with the amplitude. The lifting capacity of the tower crane varies with amplitude.

The product of the lifting capacity and the amplitude is called the load moment, which is the main technical parameter of the tower crane. Through slewing mechanism and slewing support, the lifting height of tower crane is high, the inertia mass of slewing and walking is large, so it needs good speed regulation performance. In general, besides the resistance speed regulation, Eddy current brake, frequency regulation, pole changing, silicon controlled rectifier and electromechanical combined speed regulation are also used. In order to ensure the safe production in an orderly manner, the tower crane has good safety devices, such as lifting weight, amplitude, height and load moment limiting devices As well as the trip limit switch, tower top signal lights, wind meter, wind clamp rail, climbing ring, such as the aisle fence. The driver's cab requires comfort, easy operation, good view and good communication equipment.
