132HC Mast SectionThe lifting capacity of tower crane changes with the amplitude, and the product of lifting capacity and amplitude is the load moment
The product of lifting capacity and amplitude of tower crane is called load moment, which is the main technical parameter of this 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 safety, 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 clamp, ladder body guard ring, walkway guardrail, etc. The cab shall be comfortable, easy to operate, with good vision and complete communication equipment.
We have left a deep impression on many customers with integrity, dedication and diligence. We sincerely hope to provide customers with high-quality products and satisfactory and thoughtful services.
