LOCATION AND DESCRIPTION OF MAJOR COMPONENTS AND SYSTEMS (CONTINUED)
STACKER SYSTEM
The stacker is used to transfer projectiles between the conveyor
and projectile racks.
Vertical Motion:
The sliding stacker projectile tray is connected to a roller chain that
travels between the upper drive sprocket and lower idler sprocket.
The drive sprocket is shaft-mounted to the hydraulic motor. Up-
and-down movement is controlled by two pushbutton switches
mounted on the upper back of the chain guard. The pushbuttons ac-
tuate the stacker directional control valve which allows hydraulic
fluid to the motor. The projectile tray is prevented from falling by a
hydraulic brake mounted on the motor.
A winch assembly provides manual operation of the projectile tray
when hydraulic power is unavailable.
Horizontal Motion:
Movement of the stacker from one side of the cargo compartment
to the other is accomplished by pushing the stacker manually. The
stacker is supported at the top by a horizontal cross-member, and is
guided along the vehicle floor by a wear strip. The roller bearing
assembly, mounted to the vertical support assembly, provides ease
of horizontal travel.
