Weight-Operated Limit Switches

Weight-operated limit switches are crucial for controlling the movement of hoisting equipment. When the snatch block or similar component reaches its top position, it pushes a plate connected to a lever on the limit switch. This action causes the lever to rotate, which in turn rotates the cam shaft and cams inside the switch. The cams then open the electrical contacts, disconnecting the motor and halting the hoisting motion. This mechanism effectively prevents over-travel and ensures the safe and reliable operation of the equipment.
