  Joseph BellAug 4, 2025
  If the engine runs but the platforms aren't lifting, it could be due to several reasons. First, the motor rotation might be in the wrong direction; try changing it. Second, the oil level might be low, so check and top it up if needed. Third, the safety valve could be damaged, requiring a check and possible replacement. Finally, the oil hose might be loose, so inspect and tighten it.

  Adam MartinAug 9, 2025
  A slow lifting speed can be attributed to several factors. It could be due to a low oil level, so check and top it up if necessary. The pressure relief valve might not be correctly adjusted, requiring an adjustment. The load might be too heavy, in which case you should reduce it. The oil filter could be clogged, so clean or replace it. Finally, the cylinder seal might be defective, requiring a replacement.

  If the platforms descend slowly after lifting, several issues could be the cause. A hydraulic hose might be leaking, requiring its replacement. A valve could be leaking, needing cleaning or replacement. The hydraulic cylinder might be leaking, in which case replace the seal. There might also be leaks in the pressure relief valve, so clean or replace the valve.

Why is lowering too slowly in unicraft SHB 3 Lifting Systems?
- C

  If the lowering speed is too slow, it might be because the hydraulic oil is dirty, requiring a change. Another possibility is that the oil hose has jammed, so clean the oil hose and replace if necessary. Lastly, the drain valve might be blocked too much, so open the valve further.

What to do if safety interlock does not open in unicraft SHB 3?
- S
  Sarah EatonAug 29, 2025
  If the safety interlock fails to open, it could be because the air pressure regulating valve is closed or set too low; in this case, set the air pressure to 5kg/cm2. Another potential cause is a damaged solenoid valve, which would need to be replaced.
