5.4 Operating System
The main working part of truck is fork, which are used to carry the pallet or cargo for transport and short distance
transportation. The expansion of the cylinder is realized by the control of the operating handle, and the pressure oil
is provided by the pumping station.
5.5 Electric System
The electrical system includes walking and operation control. The truck use AC electric control assembly. The
meter has a battery indicator. When the battery power is too low, the electric meter will cut off the starting control
line of the oil pump motor. The moving truck can only walk without lifting the fork, and the prompt should be
charged immediately. The motor of oil pump is the dc motor for 5 minutes, so the pump motor is not suitable for
long running. That is, the lifting movement should have time interval, cannot continuously carry on, otherwise would
make the motor heating, even burn.
Special note: when the truck is used for a long time, the starter of the oil pump motor may fail, and it can't be
broken after being sucked or closed. The latter is not throw control handle, the oil pump motor is kept in the rotation,
should immediately stop at this moment, to cut off the power supply (unplug battery plug-in), make the oil pump
motor stop running, and promptly replace the starter.
5.6 Hydraulic principle
The oil pump motor drives the gear pump to provide hydraulic power, lifting oil cylinder is responsible of fork’s
lifting and lowering, The control of the lift oil road is controlled by the buttons on the operating handle, The lifting
action is controlled by a single action oil circuit on the valve block. This model of the hydraulic system pressure can
only be adjusted on the valve block, has been debugging good, before they go out after they leave the our company
after-sales personnel or professional maintenance personnel are strictly forbidden to adjust themselves, so as to
avoid safety accident.
