5.4 Operating System
The main working body of a moving truck is a cargo fork, which relies on a fork 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, can not 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.
