Steering column for Demag AC80-1

The steering column assembly, identified by part number 634 601 40, is a central component located within the operator cab of the Demag AC80-1 mobile crane. It functions as the primary mechanical and electrical link between the steering wheel and the crane steering system. This assembly transmits the rotational input from the operator directly to the steering gearbox or hydraulic steering circuit, enabling precise control over the vehicle trajectory. In addition to steering inputs, the unit often houses integrated controls for auxiliary systems such as lighting, windshield wipers, and the horn.

This component is designed specifically for the Demag AC80-1 model. It maintains the necessary alignment and structural integrity required for steering responsiveness during both on-road travel and job site maneuvering. Proper operation of this assembly is necessary for the safe handling of the crane, as it ensures that operator inputs are accurately translated to the steering actuators. The steering column acts as the central hub for driver-operated directional control, housing the necessary linkages and electrical connections to manage the crane movement effectively.
