Boom support device for Demag AC80-1

The boom support device, identified by part number 165 840 12, serves as a structural interface for the Demag AC80-1 all-terrain crane. Its primary function is to provide a secure cradle for the boom assembly when the crane is stowed for transport or parked in a non-operational state. By locking the boom into a fixed position, the component prevents unwanted movement and structural stress during transit.

This specific part is engineered for the Demag AC80-1 model. It acts as a contact point that distributes the weight of the boom across the carrier frame, ensuring that the assembly remains stationary and aligned. Proper engagement of the support device is necessary to maintain the integrity of the boom and the associated hydraulic or mechanical systems during road travel.

In crane operations, boom supports are used to stabilize the main boom section when it is lowered from its working angle. These components ensure that the boom is held firmly in place, protecting the hoist cylinders and the slewing mechanism from excessive loads caused by road vibrations or sudden shifts during movement. Using the correct support device ensures that the crane meets the necessary configuration requirements for safe transport between job sites.
