Poweramp VEH SERIES HYDRAULIC - Manual (Page 13)

The VEH Series dockleveler is designed to compensate for +/- 12" of height differ-
ence between the loading dock and the truck bed. To position the dockleveler, the
operator utilizes the VEH Series pushbutton controls. When the raise pushbutton is
pushed and held, a motor is activated that in turn drives a hydraulic pump which
raises the dockleveler platform. Releasing the
pushbutton allows the platform to lower.
A cable attached between the platform and valve lever shifts a spool in the hydraulic
logic block redirecting the flow of oil to the lip cylinder extending the lip. After fully
extending the lip, releasing the pushbutton will allow the dockleveler to lower.
After loading/unloading, the dockleveler can be repositioned to the stored position by
depressing and holding the raise pushbutton. As the platform raises, the lip folds to
the pendant position. Once the lip clears the truck bed, the raise button can be
released allowing the leveler to lower to its level to the stored position.
The VEH Series Hydraulic dockleveler utilizes hydraulic logic and simple one button
operation for ease of use.
