The narrow profile of Flip Handle cups makes them an efficient tool for pulling sheet materials from narrow storage bins, as well as for general-purpose handling. The TL6FH is designed for gripping curved surfaces, the LP6FH for flat surfaces.
Unlike suction cups that produce a vacuum
when they are pulled away from the surface, Powr-Grip vacuum cups pump out
air from between the rubber pad and the surface, thus creating a
much more reliable hold. The hand-actuated pump is spring-balanced to
provide a vacuum of 20 inches Hg (at sea level).
A red line on the plunger indicates the
vacuum level of the hand cup. When the cup is attached completely, the
plunger is partially hidden inside the pump and the red line is not visible.
A visible red line indicates vacuum is not sufficient for a lift. If the
red line starts to show during a lift, a check valve allows the operator
to repump the cup without losing the remaining vacuum. When the lift is
completed, a release device allows air to refill the evacuated space,
so that release is complete, with no dangerous after-stick. |
