Technical Details：
A crane top roller is a type of wheel that is mounted on the top of a crane’s boom. It is designed to support and guide the hoisting rope or chain as it lifts and lowers heavy loads. The top roller enables the crane to smoothly and safely move the load along the boom’s length. It is a critical component of the crane’s lifting system and must be carefully maintained to ensure its safe and efficient operation.
