10. Power on: the plug of power cord shall be inserted into preassembled power socket.
Circuit breaker shall be installed in power supply. The power switch lights when the main
switch installed in control cabinet is opened. Press the “RISING” button to determine
whether the slide of lifter rises. If the slide does not rise, sequence of power supply shall
be changed, making the motor rotate in positive direction and oil pump supply oil normally.
In this case, lifter slide and bracket arm rise, moreover, whether the height for left slide and
right slide is uniform shall be observed. Meanwhile, the slide height shall be judged by
hearing sound of safety block. In order to guarantee the uniform position of safety blocks,
left slide and right slide, the steel wire rope shall be accurately adjusted. Upon falling, the
“FALLING” button shall be pressed and time relay shall be on. After 2 seconds, the
mechanical lock and oil return solenoid valve shall be opened. Under the weight of working
platform and lifting vehicle, the hydraulic oil in lower cavity of oil cylinder is pressured to oil
tank, and then the falling is completed. Upon vehicle maintenance, when pressing “lock
button”, the oil return solenoid valve is on and mechanical lock is off. In this case, the slide
descends, and mechanical lock resets under the self-weight and normal condition. In
addition, the slide is locked by mechanical lock. The locking can be completed and safety
operation can be performed. Upon completion of above tests, safety housing and electric
cabinet housing shall be well assembled.
11. Cleaning at site: the several times of lifting and falling of lifter and bracket arm shall be
repeated to determine whether the operation is normal. If some problems exist, such lifter
and bracket arm can be used only after the abnormal phenomenon is inspected and
eliminated following above steps. Finally, the cover plate with decorative pattern shall be
