Hydraulic system
The hydraulic system is composed of main oil pump, multi-way valve, lifting cylinder, inclined
cylinder and oil channel.
The oil pump motor drives the gear pump to provide hydraulic power, two lifting cylinders are
responsible for the lifting of the fork, two inclined cylinders complete the front and back tilt action of
the door frame, and one side cylinder completes the left and right side movement of the tray frame.
The control of lifting, tilting and lateral oil passage is controlled by three handles on the triplet valve,
the lifting action is controlled by the single acting oil passage on the triplet valve, and the tilting and
lateral movement is controlled by the double acting oil passage on the triplet valve. The hydraulic
system pressure of this model can only be adjusted on the triple valve, which has been debugged
before leaving the factory. After leaving the factory, non-after-sales personnel or professional
maintenance personnel of our company are strictly prohibited to adjust themselves, in order to avoid
safety accidents.
