What is the pulley of a crane?
As an indispensable heavy equipment in modern industry, cranes have one of their core components - the pulley system, which directly determines the operating efficiency and safety of the equipment. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the principles, types and applications of crane pulleys, and display relevant technical parameters through structured data.
1. Basic principles of crane pulleys
A pulley is a mechanical device used in a crane to change the direction of the rope or transmit power. Through the design of the pulley block, the crane can lift or move heavy objects with less force. According to different functions, pulleys can be divided intofixed pulleyandmoving pulley:
