L68B3 Mast Section Explain how the lifting capacity of tower crane changes with the amplitude as required
With the wide application of tower crane, more and more people are concerned about the technical knowledge of tower crane. They find that many friends want to know about the performance of tower crane.L68B3 Mast Section tower crane Construction Co., Ltd. (http://www.fx68.net) explains how the lifting capacity of tower crane changes with the amplitude according to the needs.

The lifting capacity of the tower crane varies with the amplitude. The product of lifting capacity and amplitude is called load moment, which is the main technical parameter of the tower crane. Through the slewing mechanism and slewing bearing, the lifting height of tower crane is large, and the inertia mass of slewing and traveling is large, so it needs to have good speed regulation performance, especially the lifting mechanism needs to be able to light load fast, heavy load slow, installation in place micro motion. In addition to resistance speed regulation, eddy current brake, frequency modulation, pole changing, thyristor and electromechanical combination are often used for speed regulation.
In order to ensure the orderly progress of safety production, the tower crane has good safety devices, such as lifting capacity, amplitude, height, load moment and other limiting devices, as well as travel limit switch, tower top signal light, anemometer, windproof rail clamping device, ladder protection ring, walkway guardrail, etc. The cab shall be comfortable, easy to operate, with good vision and complete communication equipment
