Poweramp VS VERTICAL SPECIALTY 2.1995 - Manual (Page 6)

3
This manual covers the hydraulic VS dockleveler manufactured by Poweramp. It has been
equipped with a double acting hydraulic hoist cylinder to control the raising and lowering of
the platform. Operation of the unit is via constant pressure push buttons located in a control
enclosure. It is the intent of Poweramp that the control enclosure be located above the
loading dock floor and on the loading dock side of the VS dockleveler. This will assure
operator safety, no one should ever be in the operating zone of the VS dockleveler (See
Fig.2). Whenever maintenance personnel must work beneath the VS dockleveler, the VS
dockleveler should be tightly secured to a reliable support at all times with maintenance
props engaged and locked.
Introduction
WARNING
Always operate the
equipment from atop the
loading dock. Never
stand or work under the
VS dockleveler unless it
is securely supported.
Use safe work habits.
WARNING
WHEN A HYDRAULIC
CYLINDER IS EXTENDED,
IT MUST BE FULL OF
HYDRAULIC FLUID TO
SUPPORT A LOAD.
EXTENDING HYDRAULIC
CYLINDERS BY A MEANS
OTHER THAN HYDRAU-
LIC POWER CAN RESULT
IN SEVERE PERSONAL
INJURY OR DEATH.
Poweramp has no control over the operational condition of the VS dockleveler after it leaves
the factory. If, for any reason such as damage, neglect or intentional misuse, the hydraulic
hoist cylinder is drained of fluid or the speed control is misadjusted, the VS dockleveler can
free fall from its vertical position. Should this occur, serious injury and/or damage is possible
to personnel and/or property.
