2.4 Hydraulic principle
Pump motor driven gear pump provides hydraulic power; Two lifting cylinders are
responsible for the fork lift; a tilt cylinder is for the mast tilt movements. The oil-way
for Lift-lower and tilt is controlled by two handles on the double valve, the lifting and
lowering action is controlled by a single-acting oil-way on the passage double valve,
while tilt motion is controlled by a double-acting oil-way on the double valve passage.
The hydraulic system pressure for this forklift is adjusted only on double valve, which
has been debugged in the factory. If you’re not our after-sales employee or
professional repair staff, it is not allowed to adjust, in order to avoid accidents.
