Failure hand pallet trucks may arise , analysis and troubleshooting
Fault: Lifting height below standard ;
Cause: The hydraulic oil is not enough ;
Remedy: Unplug the hydraulic hand truck tumultuous filling hole rubber stopper , injection by filtration of hydraulic mooring to stop going to overflow and Reattach tumultuous plug. Note : At this point , the goods are again in the bottom position.
Failure II: lever handle fork does not rise ;
1 working oil viscosity counter balance stackers is too large or injection work poise ;
2, working parked there impurities, so that the inlet valve does not close tightly ;
3 , unloading valve push Villa Park and into contact with too tight , the inlet valve is open moor ;
4 running boards , put the oil valve is not adjusted .
Remedy:
1 , replacement of oil or exclude impurities ;
2, the adjusting screw .
Failure three: do not drop the fork rise ;
Reason:
A piston rod partial load or overload due to excessive permanent deformation or seals killed ;
2 , partial load or overload effect , causing distortion components , moving parts turning serious friction tight ;
3, the rotating parts is not a regular refueling and killed , often highly placed , exposed parts of the piston rod rust ;
4 , failed to break open the haunted unloading valve stem .

Failure Four: Rise and fall jack lever handle and the handle has a child by playing physical phenomena or top lifting slightly declined.
