Crane wheels are replaced because of flange wear, flange breakage, and mechanical overloads characterized by pitting and spalling. Each of these inservice factors must be carefully considered before the combination of wheel design, material selection, hardness pattern and heat treating technology is selected.
A pulley is a set of simple tool consisted of one or more wheels over which a rope can be looped for the purpose of labor saving and movement direction changing. Pulleys can be divided into crown block/ fixed pulley and fall block / movable pulley based on functions of pulleys while based on materials, pulley blocks can be classified into cast iron pulley, cast steel pulley, nylon pulley, and aluminum pulleys, etc.
Crane rope drum is a part of crane lifting mechanism which is used to full in, entwine, and store wire rope. The rope drum is consisted of drum shaft, flange type annular gear, drum hub, bearings, bearing pedestal, etc. Every part of crane rope drum is engineered and manufactured to meet the operational and safety requirements of industrial crane applications.
Overload limiter for material handling equipment is the necessary device to prevent crane accidents caused by dangerous operation of lifting weight exceeding the rated lifting capacity of the material handling equipment. The overload limiter contributes greatly to the safety of lifting equipment and operation staffs.
Weight overload limiter is a protection device used on various wire rope electric hoists. The weight overload limiter is designed with humanized features and various functions to meet the requirements of different customers in different applications with the advantages of simple structure, high security, easy installation and convenient to use and maintenance, etc.
