Poweramp E SERIES HYDRAULIC 11_96 - Manual (Page 13)

The E Series dockleveler is designed to compensate for +/- 12" of height difference
between the loading dock and the truck bed. To position the dockleveler, the opera-
tor utilizes the E 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 E Series Hydraulic dockleveler utilizes hydraulic logic and simple one button
operation for ease of use.
