Boom brake band for Link-Belt LS318

The 21E38 boom brake band serves as a primary control element within the braking system of the Link-Belt LS318 crane. This component utilizes PX422 lining to engage with the brake drum, providing the necessary friction to regulate the movement of the boom or to secure a suspended load. By managing the rotational speed of the winch drum, it allows the operator to control the descent of the boom or the hoist line during lifting operations.

This component is specifically engineered for the Link-Belt LS318 crane. The brake band assembly is manufactured to meet the operational requirements of the machine's lifting system, ensuring compatibility with the existing brake drum and mechanical linkages. Regular inspection of the brake band and the PX422 lining is necessary to monitor for wear, as the friction material is subject to thermal stress during standard crane operation.

Brake bands are used in heavy machinery to provide mechanical resistance to rotating drums. By applying pressure to the exterior of the drum, the band converts kinetic energy into heat, allowing the operator to stop or hold a load in a fixed position. Maintaining the integrity of the brake band and its lining is necessary for the consistent performance of the crane's hoisting and luffing functions.
