How Do Hoist Cranes Work?
Hoist crane is a unified tool that has a certain working principle. The two are truly inseparable from each other. There are at least two working systems of this tool, namely manual and electric hoist. The manual version of the work system is operated without using electricity and applies the working principle of using a pulley. Meanwhile, the electric hoist system is operated using electricity exactly as the name suggests. In addition, the mechanical work process of this tool system is also divided into two. The work process includes using a chain or chain hoist and using a wire rope/sling hoist. This process uses routine maintenance that is at least 1 to 2 times a year.
