CURBTENDER Quantum Compact - Packing Controls

PACKING CONTROLS
(THE TAILGATE/ MAIN VALVE IS LOCATED AT THE UPPER RIGHT HAND SIDE OF THE TAILGATE)
The Quantum Compact incorporates the backhoe principle of operation. Two panels make up the
backhoe, the Sweep Panel (lower) and the Swing Panel (upper).
The Swing Panel slides up and down the tailgate on replaceable guide blocks. Two double acting
swing cylinders, one located on each side of the Swing Panel, provide the power.
The Sweep Panel is attached to and pivots on the Swing Panel. The Swing Panel carries the Sweep
Panel and supports the two cylinders.
The two panels are controlled by movement of two packing control levers located on the right side
of the tailgate. These two packing control levers are linked to the hydraulic tailgate/main valve which
directs hydraulic  uid to the packing panel cylinders.
The tailgate/main valve is located on the right upper side of the tailgate. The two packing control le-
vers are connected to this valve. The top packing control lever controls the movement of the Sweep
Panel and the bottom packing control lever controls the movement of the Swing Panel. The valve sec-
tions are detented to “kick-out” the valve spool back to neutral when a pre-set pressure of the valve is
reached, such as when a cylinder is “bottomed-out” at the end of the stroke. Four distinct movements
of the two blades make up the packing cycle. The cycle starts with the Swing Panel fully up or in the
pack position, and the Sweep Panel down.
1) SWEEP PANEL (UP)- The sweep panel is raised when the top packing control lever is pulled
outward from the tailgate.
2) SWEEP PANEL (DOWN)- The sweep panel is lowered when the top packing control lever
pushed inward toward the tailgate.
3) SWING PANEL (DOWN)- The Swing Panel is lowered when the bottom packing control
lever is pulled outward from the tailgate.
4) SWING PANEL (UP)- The carriage panel is raised when the bottom control lever is pushed
inward toward the tailgate.
