Counterweight top for Demag AC80-1

The top counterweight, part number 587 042 40, is a structural weldment designed for the Demag AC80-1 crane. This component is positioned to provide the required stability for the crane during lifting operations. Its function is to compensate for the overturning moment generated by the weight of the load and the extension of the crane boom. By adding mass to the side opposite the load, this counterweight helps maintain the center of gravity of the crane within its support base.

This component is specifically engineered for the Demag AC80-1 model. It serves as a key element of the counterweight system, which is configured to match the lifting capacity and operational requirements of the machine. Proper installation and maintenance of this assembly are required to ensure the crane operates within its design parameters.

Counterweights are used in mobile cranes to counteract the load moment. By placing weight behind the rotation axis, the counterweight system shifts the center of gravity away from the load, which increases the tipping threshold and allows the crane to handle heavier loads at greater radii while maintaining structural stability.
