  & nbsp; Regularly inspect the circuit system of the hydraulic lifting platform for any looseness, check for aging or damage to the wires and cables, and prevent electrical leakage. If there is, repair it promptly to avoid electric shock. In some cases, even if the above three conditions are not cleared, there may still be noise. If there is no problem after investigation, there is no need to worry. It is just a problem of running in between mechanical parts. After running a few more times, the noise will naturally disappear.

  & nbsp; Overall, regardless of the situation where the oil cylinder is making a loud noise, the editor still advocates contacting the manufacturer to investigate the cause. The oil cylinder is still an important part of the entire hydraulic system, and it is very risky to disassemble it yourself! Before using the high-altitude work platform, it is necessary to confirm whether the support legs are properly and firmly supported, and refer to the horizontal beads on the equipment for judgment and debugging before proceeding with the operation.

  & nbsp; Confirm whether the roller tracks of the hydraulic lifting platform are dry. If there is a dry site, add an appropriate amount of butter to ensure that the slides are moisturized during operation and avoid hard wear and tear between mechanical parts.
