Boom brake band for Link-Belt LS318

The boom brake band, part number 21E41, serves as a component within the boom hoist brake system of the Link-Belt LS318 lattice crawler crane. Its primary function involves applying friction to the drum to stop or hold the boom in a fixed position, allowing the operator to maintain control during lifting and lowering maneuvers. This component is engineered to interface with the crane's mechanical braking assembly to ensure precise load handling.

This specific part is compatible with the Link-Belt LS318 model and includes PX422 friction lining. The brake band consists of a semi-rigid metal structure that supports the friction material, which is intended to engage with the brake drum surface. Proper maintenance of the brake band and its lining is necessary to ensure the braking system functions according to the machine's operational requirements.

In crane systems, brake bands are used to manage the rotational speed of winches or drums. By applying pressure to the drum, the band creates the resistance required to prevent the boom from moving unintentionally. Regular inspection of the friction surface is standard practice to monitor for wear and ensure the braking mechanism continues to operate as intended.
