The main maintenance details of the electrical equipment of a single beam crane include the following aspects:

Cleaning and Inspection:

Regularly clean the surface of electrical equipment, such as control boxes, contactors, etc., to prevent leakage, breakdown, short circuits, and other phenomena caused by the accumulation of dust, oil stains, etc.

Check if the casing of electrical equipment is intact and free from damage, deformation, etc.

Electrical circuit inspection:

Regularly inspect the electrical circuits, wiring terminals, and other equipment to ensure that the wiring is secure and free from looseness or detachment.

Check if the wires are aging, broken, or exposed, and replace them promptly if any problems are found.

Electrical component maintenance:

Regularly check the working status of electrical components (such as contactors, relays, circuit breakers, etc.) to ensure their good performance.

Perform necessary lubrication, tightening, and other operations on electrical components to ensure their normal operation.

Motor maintenance:

Regularly check the operation of the motor, including temperature, sound, etc., and promptly handle any abnormalities found.

Regularly lubricate and maintain the motor to ensure good lubrication of motor bearings and other components.

Safety device inspection:

Check if the safety devices of the crane (such as limit switches, emergency stop buttons, etc.) are intact and effective.

Regularly test safety devices to ensure they can function properly in emergency situations.

Cable and power line maintenance:

Regularly check the connection status of cables and power lines to ensure no looseness, damage, or other issues.

Clean the dust and oil on the cables and power lines to prevent short circuits and other faults caused by water contamination.

Electrical system testing:

Regularly test the electrical system, including measuring parameters such as voltage, current, and insulation resistance.

Timely detection of potential issues in the electrical system through testing to ensure the safety and reliability of the crane's electrical system.

Lubrication and tightening:

Lubrication and maintenance of the transmission components of electrical equipment to reduce wear and friction.

Regularly inspect the fasteners of electrical equipment to ensure that there is no looseness.
