Complete Guide to Troubleshooting Stage Electric Gourd II

　　1、 Electric hoist slides down

　　(1) Check the brake system

　　The brake is a key component that prevents the electric hoist from sliding down. Check if the brake pads of the brake are severely worn and if the brake springs are loose.

　　If the brake fails, the brake components should be adjusted or replaced in a timely manner.

　　(2) Check the motor

　　Motor malfunction may cause the electric hoist to slide down. Check if the brake device of the motor is working properly and if the motor is reversing.

　　If there is a problem with the motor, professional maintenance personnel should be contacted for repair.

　　(3) Check the load

　　Overloading or imbalance may also cause the electric hoist to slide down. Check if the load exceeds the rated load of the electric hoist and if it is evenly distributed on the hook.

　　Adjust the load to be within the carrying range of the electric hoist and maintain balance.

　　2、 Electric hoist has excessive noise

　　(1) Check the motor

　　The noise generated during motor operation may be due to wear, looseness, or bearing damage of internal components of the motor. Check if there are any abnormalities in the appearance of the motor and listen for any abnormal sounds when the motor is running.

　　If the motor malfunctions, it should be repaired or replaced in a timely manner.

　　(2) Check the transmission system

　　Wear or looseness of components such as gears, sprockets, and chains in the transmission system can also generate noise. Check the condition of the transmission components and replace or adjust them promptly if there are any problems.

　　Regularly add lubricating oil to reduce wear and noise of transmission components.

　　(3) Check the steel wire rope

　　Friction between steel wire rope and components such as drums and pulleys during operation can also generate noise. Check the condition of the steel wire rope to ensure it is running on the correct track.

　　If necessary, replace worn pulleys or adjust the tension of the steel wire rope.

　　3、 Electric hoist operation is not flexible

　　(1) Check the remote control or handle

　　Remote control or handle malfunction may cause the electric hoist to operate inflexibly. Check if the battery of the remote control is fully charged and if the buttons on the controller are sensitive.

　　If there is a problem with the remote control or handle, the battery should be replaced or repaired in a timely manner.

　　(2) Check the limit switch

　　The limit switch is an important component that limits the operating range of an electric hoist. Check if the limit switch is working properly and if there is any looseness or damage.

　　If the limit switch malfunctions, it should be adjusted or replaced in a timely manner.

　　(3) Check the mechanical structure of the electric hoist

　　Loose or deformed mechanical structure of electric hoists can also affect the flexibility of operation. Check whether the connections of each component are firm and whether there is any deformation.

　　If necessary, tighten or replace damaged components.

　　In short, various malfunctions may occur during the use of stage electric hoists, and we need to promptly troubleshoot them to ensure the smooth progress of stage performances. When troubleshooting, the specific symptoms and possible causes of the fault should be determined first, and then corresponding measures should be taken for maintenance.

　　If you are unable to troubleshoot the problem yourself, you should promptly contact professional maintenance personnel for inspection. Do not disassemble the electric hoist without authorization to avoid causing greater damage.

　　At the same time, in order to reduce the occurrence of faults in electric hoists, we should also regularly maintain and upkeep them, including cleaning, lubrication, inspection, and other work, to ensure that the electric hoist is always in good operating condition.
