The inspection items during the initial installation of the electric hoist are crucial to ensure the safety and normal operation of the equipment. Here are some main inspection items:
1、 Equipment appearance and integrity inspection
Check equipment integrity: Ensure that all components (such as motors, reducers, chains/wire ropes, control boxes, etc.) are complete and free from obvious damage.
Check the packaging condition: Pay attention to whether the packaging is intact and whether there is any damage or deformation caused during transportation.
2、 Electrical system inspection
Power supply and cables: Check whether the power supply meets the equipment requirements, whether the cable cross-sectional area is sufficient (generally not less than 2.5 square millimeters), and ensure that the cable connection is firm and the insulation is good.
Electrical control box: Check whether the control box has the specified protection level (such as IP54), whether the internal wiring is neat and standardized, and whether there is any exposure or misconnection.
Motor insulation: Check whether the insulation type of the lifting motor and the walking motor meets the regulations to ensure the safe operation of the motor.
3、 Mechanical system inspection
Lubrication condition: Check whether all parts that need lubrication, such as reducers, walking mechanisms, etc., have been adequately lubricated with grease.
Chain/wire rope: Check whether the diameter of the chain and wire rope meet the requirements, whether the fixed end of the wire rope is firm, and whether there is any looseness or disorderly winding.
Hook and safety device: Check whether the hook is coated with anti rust paint (such as yellow and black alternating paint), and whether the safety device is complete and effective.
4、 Installation position and fixing situation
Site assessment: Ensure that the installation site is flat and has sufficient load-bearing capacity (at least 2.5 tons/square meter).
Installation position: Accurately calculate and determine the optimal installation position based on the specifications of the crane, ensuring that the work area covers at least 95% of the work area.
Fixed and adjusted: Use high-precision tools to fix and adjust the electric hoist to a horizontal deviation of no more than 0.5 degrees and a vertical deviation of no more than 2 millimeters.
5、 Safety device inspection
Limit switch: Check whether the up and down limit switches are sensitive and reliable, ensuring that the power can be automatically cut off when the limit position is reached.
Load limiter: If equipped with a load limiter, it is necessary to check whether it can automatically cut off the power supply when overloaded.
Emergency stop button: Check if the emergency stop button is easy to reach and responds quickly.
6、 Trial operation testing
No load test run: After connecting the power supply, conduct a no-load test run to check whether each mechanism is working properly, and whether the control buttons, limiters, and other devices are sensitive and reliable.
Full load trial operation: Conduct a full load trial operation at rated load to check whether the operation is smooth and whether the safety device is effective.
7、 Other precautions
Qualification of installation personnel: Ensure that installation personnel have the corresponding qualifications and experience.
Safety training: Provide safety training to all operators to ensure they understand equipment operating procedures and emergency response measures.
Regular inspection and maintenance: Develop a regular inspection and maintenance plan to ensure the long-term stable operation of the equipment.
