Pulley for Linden Comansa 21LC750/36t

The pulley, part number 3205-20214, is a mechanical component used in the hoisting systems of tower cranes. It serves to guide and support the steel wire rope, allowing for the lifting and movement of loads. This component is integrated into the hook block, the jib head, or the trolley system, where the wire rope passes through it to change the direction of traction or to adjust the mechanical advantage of the lifting system. Proper alignment and rotation of the pulley allow for the controlled movement of the load during crane operations.

This specific component is compatible with the Linden Comansa 21LC750/36t tower crane. The design of the pulley groove is matched to the diameter of the wire rope specified for this crane model to ensure the cable remains seated during operation. The pulley facilitates rotation to minimize friction against the wire rope as it moves through the reeving system.

In crane machinery, pulleys are used to redirect cables and distribute the load across multiple lines. By routing the wire rope through these components, the crane operator can achieve the necessary lifting capacity and reach required for construction tasks. Maintenance of the pulley groove and internal bearings is necessary to ensure consistent performance of the hoisting system.
