Limit switch for Link-Belt HC238H

The limit switch CBR0473 functions as an electromechanical sensor within the control systems of Link-Belt cranes. It detects the presence of an object or the travel of a mobile component beyond a set point, transmitting an electrical signal to the crane controller to halt or modify movement. This action assists in managing boom limits, elevation angles, cable extension, and slewing operations to keep the machine within defined operational parameters.

This component is compatible with the Link-Belt HC238H lattice crawler crane. The switch utilizes an internal actuator mechanism, such as a plunger, roller, or lever, to engage electrical contacts when a specific position is reached. These contacts are configured as normally open or normally closed to facilitate the required circuit logic for the machine's safety systems.

Limit switches are used across heavy machinery to define the boundaries of mechanical motion. By monitoring the physical travel of structural elements, they provide the necessary feedback to prevent over-travel or unintended contact between crane assemblies. Regular inspection of these switches ensures that the control system receives accurate data regarding the current state of the crane's moving parts.
