Tower Crane Guide Wire Rope Lifting Pulley

Structure and Components

• Pulley Wheel: The central part of the lifting pulley is the pulley wheel, which is typically made of high - strength steel or other durable materials. It has a smooth, grooved surface that is precisely machined to accommodate the wire rope. The groove is designed to prevent the wire rope from slipping off during operation and to distribute the load evenly across the rope's cross - section.
• Bearing Assembly: The pulley wheel is mounted on a set of high - quality bearings. These bearings allow the pulley wheel to rotate freely with minimal friction, reducing wear and tear on both the pulley and the wire rope. The bearing assembly is usually sealed to prevent the ingress of dust, dirt, and moisture, which could otherwise damage the bearings and affect the pulley's performance.
• Pulley Frame: The pulley frame provides structural support for the pulley wheel and bearing assembly. It is made of strong and rigid materials, such as cast iron or welded steel plates, to withstand the forces exerted by the wire rope and the load. The frame is designed to be mounted securely on the tower crane's structure, ensuring stability during operation.
• Wire Rope Guide: In some cases, the lifting pulley may be equipped with additional wire rope guides. These guides help to keep the wire rope in the correct position on the pulley wheel, especially during complex lifting operations or when the crane is subjected to side - loads. The guides can be in the form of flanges on the pulley wheel or separate guide plates attached to the pulley frame.
