8.2 SYSTEM FRAME
CASTERS
Occasionally check and lubricate the casters to ensure that they are firmly attached to the frame.
Two of the casters are capable of be locked for stabilizing the machine while in operation. Check
the locks to ensure that they are functioning properly. If the locks fail to work, replace as soon as
possible.
HEIGHT ADJUSTMENT SYSTEM
The frame is designed to allow the operator to adjust the vertical height of the PBC system. The
vertical adjustment is controlled by two threaded rods, located within the two main vertical tubes
of the frame. (
Illustration 8.2
) The standard PBC 6000 utilizes a crank handle, sprocket gears
and a chain to turn threaded rods. A locking lever is located near the handle to keep the machine at
the specific height. The PBC 6000 can be ordered with a motorized system to turn the threaded
rods.
To prevent the threaded rods from going too far to the ends of the threads on a motorized lift
system, proximity switches have been installed on the vertical tubes of the frame. The lift motor is
automatically turned off before either end of the threaded rod is reached. Weld beads on the
threaded rods help prevent the manual systems from turning too far.
8.3 PNEUMATICS
The air source connection has a female quick release air coupling (Foster Series 3, #3003 or
equivalent) which connects to the safety shut-off valve located on the pneumatic control panel
(
Illustration 8.3
). Air hose connections should have a minimum 1/2 in. (13 mm) ID. The PBC
6000 requires compressed, clean, non-lubricated air. The supply should be capable of sustaining
90 PSI (6,2 bar) of pressure and a volume flow rate of at least 420 SCFH (11,9 SCMH).
