Working principles of hydraulic system:
When the button is pressed to start the motor on the
power unit, the motor 2 will be actuated to put the oil pump
1 into motion; and oil will be sucked from the oil tank and
sent to cylinder 9 forcing the piston move upward. At this
time, the safety vale 5 is closed. (The pressure is well
adjusted before leaving the factory to ensure the rated
capacity. However, when the system pressure exceeds the
limit, the oil will automatically overflow). When the start
button is released, the oil supply will stop so as to stop the
lifting. For lowering the carriage, first start up the motor to
raise the carriage a little, pull the safety lock handle on the
column to disengage the safety locking status; and then
press the manual lowering handle valve 6 to lower the
carriage.
