Key points for inspection of stage electric hoist equipment

　　1、 Appearance inspection

　　(1) Check whether the shell of the electric hoist is damaged, deformed or cracked. If any problems are found with the outer shell, it should be repaired or replaced in a timely manner to prevent damage to the internal parts.

　　(2) Check if the hook is deformed, cracked, or worn. The hook is an important component of the electric hoist, which directly affects the safety performance of the equipment. If there is a problem with the hook, it should be immediately stopped and replaced.

　　(3) Check if the chain is worn, broken, or twisted. The chain is the transmission component of an electric hoist, and its quality directly affects the lifting capacity and safety of the equipment. If there is a problem with the chain, it should be replaced promptly.

　　2、 Electrical system inspection

　　(1) Check if the power cord of the electric hoist is damaged, short circuited, or has poor contact. If there is a problem with the power cord, it should be repaired or replaced in a timely manner to prevent electrical accidents.

　　(2) Check if the control buttons of the electric hoist are sensitive and reliable. The control button is the operating component of the electric hoist, and its performance directly affects the convenience and safety of equipment operation. If there is a problem with the control button, it should be repaired or replaced in a timely manner.

　　(3) Check if there are any abnormal noises, heating, or vibrations in the motor of the electric hoist. The motor is the power source of the electric hoist, and its performance directly affects the lifting capacity and safety of the equipment. If there is a problem with the motor, it should be repaired or replaced in a timely manner.

　　3、 Mechanical system inspection

　　(1) Check the gearbox of the electric hoist for oil leakage, abnormal noise, or overheating issues. The gearbox is the transmission component of the electric hoist, and its performance directly affects the lifting capacity and safety of the equipment. If there is a problem with the gearbox, it should be repaired or replaced in a timely manner.

　　(2) Check if the brake of the electric hoist is sensitive and reliable. The brake is a safety component of the electric hoist, and its performance directly affects the safety of the equipment. If there is a problem with the brake, it should be repaired or replaced in a timely manner.

　　(3) Check if the limit device of the electric hoist is sensitive and reliable. The limiter is a safety component of the electric hoist, and its performance directly affects the safety of the equipment. If there is a problem with the limiter, it should be repaired or replaced in a timely manner.

　　4、 Safety device inspection

　　(1) Check if the overload protection device of the electric hoist is sensitive and reliable. Overload protection device is a safety component of electric hoist, and its performance directly affects the safety of the equipment. If there is a problem with the overload protection device, it should be repaired or replaced in a timely manner.

　　(2) Check if the anti fall device of the electric hoist is sensitive and reliable. The anti fall device is a safety component of electric hoists, and its performance directly affects the safety of the equipment. If there is a problem with the anti fall device, it should be repaired or replaced in a timely manner.

　　(3) Check if the emergency stop button of the electric hoist is sensitive and reliable. The emergency stop button is a safety component of the electric hoist, and its performance directly affects the safety of the equipment. If there is a problem with the emergency stop button, it should be repaired or replaced in a timely manner.
