An overload protection device is crucial for a building hoist to prevent accidents caused by excessive weight. First, ensure the device is correctly installed and calibrated according to the manufacturer's instructions. Before operating the hoist, set the overload limit based on the hoist's capacity. During operation, if the load exceeds the set limit, the device should automatically shut down the hoist, preventing further operation. Regularly inspect and test the device to ensure it functions properly. Always follow safety protocols and never attempt to bypass or disable the overload protection system.
