Boom sheave for Demag AC 615

The boom sheave, identified by part number 49660240, serves as a component within the hoist system of the crane. Its primary function is to guide the steel hoist cable along the boom, allowing the traction force to be transmitted for lifting and positioning loads. By changing the direction of the cable and distributing forces, the sheave manages the tension applied to the lifting assembly.

This component is designed for the Demag AC 615 all-terrain crane. It is typically installed at the boom tip or the boom head, where it supports the high tension forces exerted by the hoist cable during operation. Proper alignment and a correct groove profile are necessary to maintain the cable path and support the dynamic loads encountered during crane use.

In any crane hoist system, sheaves are used to redirect cables and provide mechanical advantage. They are engineered to minimize friction and prevent premature wear on the wire rope. Regular inspection of the sheave groove and rotation is standard practice to ensure the integrity of the lifting system and to prevent damage to the hoist cable.
