BRIDGE ADAPTER PALLET CONTROLS AND INDICATORS (Contd)
HAND PUMP — The hand pump is mounted on the BAP and is used to
supply pressure to operate cylinders that raise and lower the center roller and
transload rollers on the BAP. The hand pump consists of a fluid pump, pump
lever and handle, selector valve, and reservoir.
SELECTOR VALVE LEVER — There is a three-position selector lever on
the hand pump valve. When the lever is turned to the No. 1 position (lever
up), operating the hand pump will raise the center roller to lift the bay. The
No. 1 position is also used to lower the BAP during transloading by releasing
fluid pressure to allow the transload rollers to hinge upward. Turning the
lever to the No. 2 position (lever at center) shuts off the selector valve for
transit. When the lever is turned to the No. 3 position (lever down), operating
the pump will move the transload rollers down to lift the BAP. The No. 3
position is also used to release fluid pressure to lower the center roller.
PUMP HANDLE — There is a handle secured to the pump lever on the hand
pump. The hand pump is operated by moving the pump handle back and forth
until the center roller or transload rollers are extended. Prior to pumping, the
lever lock pin is removed from the pump lever, and the selector valve lever is
turned to the desired position.
