P&H
Weight limit switch for P&H 2 ton and 5 ton cranes
This weight limit switch monitors load levels on P&H overhead cranes and hoist systems. It integrates with the lifting mechanism to detect tension and prevent operation beyond rated capacities for 2-ton and 5-ton models.

The weight limit switch R37705D1 serves as a safety device within the lifting system of P&H cranes and hoists. It monitors the load being lifted and triggers a signal or interrupts power to the hoist motor if the weight exceeds the defined threshold. By detecting tension changes or structural deformation under load, this component prevents overloading of the crane structure and the lifting mechanism.
This part is compatible with P&H overhead cranes and specific lifting equipment with 2-ton and 5-ton capacities. It is designed to integrate into the crane control system, typically mounted near the hoist or cable assembly to provide accurate feedback on load status. Proper calibration of this switch is required to maintain the specified load limits during daily operations.
Weight limit switches function by detecting force or displacement within the hoisting system. They act as a protective barrier in industrial lifting environments, ensuring that the crane operates within its design parameters. These devices are engineered to maintain consistent activation points, providing a reliable signal to the control system to halt lifting operations before structural damage or safety hazards occur.
