Maintenance methods of Telescopic Spreader

1. Mechanical parts maintenance

Telescopic mechanism maintenance: Check the telescopic beam regularly. Check whether there are signs of wear, deformation or corrosion on the surface of the telescopic beam. If wear is found, the degree of wear should be assessed in time. For minor wear, repair measures can be taken, such as grinding, repair welding, etc.; severely worn telescopic beams need to be replaced.

Check the driving components of the telescopic mechanism. If it is hydraulically driven, check the quality, quantity and temperature of the hydraulic oil regularly. Deterioration of the oil quality will affect the performance of the hydraulic system and needs to be replaced in time; insufficient oil may cause poor telescopic movement, so add oil according to the specified oil level standard. At the same time, check the sealing condition of the hydraulic cylinder to prevent hydraulic oil leakage. If the seal is damaged, replace the seal ring in time. For telescopic mechanisms driven by electric push rods, check the wear of the motor and transmission parts, clean them regularly and add lubricants.

Maintenance of the twist lock mechanism: The twist lock is a key connecting component, and the wear and deformation of the twist lock should be checked. After each use, check whether the part where the twist lock head contacts the container corner piece is worn. If worn, it should be repaired or replaced in time. At the same time, check the rotation flexibility of the twist lock to ensure that the twist lock can be locked and unlocked smoothly. Lubricate the rotating shaft and connecting parts of the twist lock regularly to prevent rust and jamming.

2. Electrical system maintenance

Electrical component inspection: Regularly inspect the electrical components on the Telescopic Spreader, such as control buttons, limit switches, sensors, etc. Check whether the electrical components are damaged, loose, or have poor contact. Damaged electrical components should be replaced in time; loose components should be re-fixed and the wiring should be checked to see if they are secure.

Check the insulation of the electrical circuit to prevent leakage. Especially in humid or harsh working environments, pay more attention to the maintenance of the electrical circuit. You can use an insulation resistance meter to regularly test the insulation resistance of the circuit. If the insulation resistance is found to be too low, find the damaged part of the insulation and repair it.

3. Overall structure maintenance

Frame inspection: Check the frame structure of the Telescopic Spreader to see if there are any cracks, deformation or looseness. For the welded parts of the frame, perform flaw detection and regularly check whether the welds have cracks. If problems are found in the frame structure, take repair or reinforcement measures according to the degree of damage.

Clean the surface of the frame to remove dust, oil and debris. After working in an environment with corrosion risks, anti-corrosion treatment should be carried out in time, such as spraying anti-corrosion paint, to prevent the frame from rusting and corrosion.
