Limit switch for P&H 15 ton crane

The limit switch is an electromechanical device that detects the position of machine components or the end of a travel range. By sending an electrical signal to the control system, it establishes safety boundaries for movements such as boom extension, hook elevation, or superstructure rotation. This component helps prevent over-travel by opening or closing electrical circuits, ensuring the machine operates within its intended parameters.

This specific part is compatible with P&H 15 ton cranes. Limit switches of this type function by utilizing an internal actuator, such as a roller or plunger, which is triggered by the physical movement of a crane component. Once engaged, the switch interrupts or completes the circuit to stop the motion of the assembly. These devices are used across various heavy machinery applications to provide precise feedback to the operator and the control system, which is necessary for maintaining operational safety and preventing mechanical interference during lifting or positioning tasks.
