Cable reel LWG 156 for Grove

The cable reel 9333101523 is an electrical and mechanical component used in Grove telescopic and mobile cranes. Its primary function is to supply electrical power or control signals to components located on the boom or the upper structure of the crane, such as lights, sensors, or safety systems. The reel manages the extension and retraction of the cable as the boom length changes, keeping the cable organized during crane operation.

This LWG 156 model is configured with a two-conductor cable to facilitate specific electrical transmission requirements. Cable reels in these systems typically utilize a spring-loaded or motorized mechanism to maintain constant tension on the cable, preventing slack or excessive strain during boom movement. Internal rotary electrical contacts, often referred to as slip rings, allow for continuous electrical connection while the reel rotates.

In crane systems, the cable reel ensures that power and data signals remain uninterrupted during the full range of boom extension. Proper tensioning prevents the cable from becoming entangled or damaged by the mechanical components of the boom assembly. Regular inspection of the cable and the reel mechanism is necessary to ensure the continued integrity of the electrical supply to boom-mounted equipment.
