Poweramp RAIL RAMP SPECIALTY 1.1995 - Manual (Page 6)

Poweramp has no control over the operational condition of the railramp after it leaves the
factory. If, for any reason, damage, neglect or intentional the hydraulic hoist cylinder is
drained of fluid or the speed control is misadjusted, the railramp can free fall from its vertical
position. Should this occur, serious injury and/or damage is possible to personnel and/or
property.
This manual covers the hydraulic railramp manufactured by Poweramp. It has been equipped
with a double acting hydraulic hoist cylinder to control the raising and lowering of the plat-
form. Operation of the unit is via constant pressure pushbuttons located in a control enclo-
sure. 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 railramp. This will assure operator safety, no
one should ever be in the operating zone of the railramp (See Fig.2). Whenever maintenance
personnel must work beneath the railramp, the railramp should be tightly secured to reliable
support at all times.
