The trailer coupling, part number 640 590 40, serves as the primary connection point for towing a dolly or trailer behind the Demag AC80-1 all-terrain crane. By providing a secure link between the crane and its towed load, this component enables the efficient transport of counterweights and auxiliary equipment, assisting in compliance with road weight regulations and logistics requirements.
This coupling is engineered specifically for the Demag AC80-1. It features a locking mechanism designed to maintain a firm connection between the crane and the trailer during transit, even when navigating uneven terrain or executing maneuvers. Regular inspection of the coupling mechanism is necessary to ensure the integrity of the connection and to maintain safe operating conditions during road transport.
Trailer couplings function as the interface between a self-propelled machine and a towed load, absorbing the longitudinal forces generated during acceleration, braking, and travel. By securing the trailer to the crane, the coupling ensures that the towed unit follows the path of the towing vehicle while maintaining the stability of the entire transport configuration.
