The parking brake is mainly used for parking state, to prevent accidents caused
by slip slope. Equipped with a limit switch on the parking brake, the control circuit is
closed under a parking state. The parking brake must be released before starting to
walk, only after that the control circuit can be switched on. The parking brake has
adjustable elastic function.
2.2.4 Operating system
The main working part of the forklift is forks. The forks realize the loading and
unloading, stacking and short-distance transportation for pallets or cargo.
Forks mounted on the carriage, by chain drive or inner mast moves up and down,
the carriage makes the goods off the ground or stacked on shelves. The chain
transmission and inner mast overall movement are achieved by the stretching of the
lift cylinder. Forklift operation process is achieved by stretching of the control
cylinders (including tilt action).
Cylinder movement is controlled by a manual valve stem, and the pressure oil is
provided by the pump station.
The safety valves in the circuit of lifting cylinders and tilt cylinder slow down
the speed of mast lifting and falling or tilting forward, which ensures the safety drop.
