The A-RCI/ATB cable reel, part number 861-90386, serves as the interface for the Rated Capacity Indicator and Anti-Two Block systems on the Terex BT4792. It maintains the integrity of the electrical connection between the crane superstructure and the boom-mounted sensors during operation. As the boom length changes, the internal mechanism manages the cable extension and retraction to prevent tangling or damage to the wiring harness.
This component is designed specifically for the Terex BT4792 model. It facilitates the transmission of data from the load sensors and the anti-two block switch back to the crane control system, allowing the operator to monitor load limits and prevent the hook block from contacting the boom tip.
Cable reels of this type are used in crane systems to house and protect the electrical cables that follow the movement of the boom. By providing a constant tension, they ensure that the cables remain organized and connected throughout the full range of motion of the machine, which is necessary for the accurate operation of safety limiters and monitoring equipment.
