Counterweight plate for Demag AC80-1

The counterweight plate, part number 611 891 40, serves as a mass component for the Demag AC80-1 all-terrain crane. It is mounted on the rear of the crane superstructure to provide the necessary ballast for lifting tasks. By adding this specific weight, the component helps maintain the stability of the crane when the boom is extended or when handling heavy loads. It is engineered to integrate with the existing counterweight system of the machine.

This plate has a weight of 2.55 metric tons. It is compatible with the Demag AC80-1 model. Proper installation of this component is necessary to ensure the crane operates within its specified load charts and stability parameters.

Counterweight plates are used in mobile cranes to counteract the overturning moment created by the load and the boom. By shifting the center of gravity toward the rear of the machine, these plates allow the crane to lift its rated capacity safely. The total counterweight configuration is adjusted based on the specific lift requirements and the crane's current setup.
