　　Cranes in manufacturing, mining, construction, stations and warehouses, etc. work for a long time and high intensity. Long-term high-strength work can easily cause damage to crane components. In order to reduce the lifting pressure of the crane and improve its working efficiency, pulleys or pulley sets are often used to assist in lifting.

　　Types of commonly used pulleys for cranes

　　The pulleys commonly used by cranes can be divided into cast iron pulleys, cast steel pulleys, welded pulleys, nylon pulleys and aluminum alloy pulleys according to different manufacturing methods. The selection of pulley material can be comprehensively considered based on factors such as lifting weight, working level and explosion-proof requirements. Generally speaking, cast steel pulleys and hot-rolled pulleys are used in occasions where the lifting weight is small and the working level is low. However, the application situation of pulleys is not static and must be decided based on the specific work content of the crane.

　　Precautions for using pulley sets

　　The more frequent the crane pulley set is used, the more severe the wear. Therefore, during the use of the crane, the wear of the slide rope should be checked regularly. If the pulley rope jumps, the rope core runs out, wave deformation, etc., it needs to be replaced in time. When updating the pulley set, pay attention to whether the pulley is equipped with anti-rope groove devices to ensure that the pulley rope groove and rim are free of cracks, edge breakage, wear, etc., and check the rotation of the pulley to ensure that it rotates flexibly.
