Packer Panel Sweeps Hopper
Operator Action
Operator shifts the control levers outward to start compaction.
Hydraulic Sequence
Fluid flows through the MCV (Main Control Valve) packer section to the case end of the packer
panel cylinders. As the cylinders extend, the packer panel sweeps the load forward in the hopper. As
the packer cylinders extension stroke continues, pressure builds to 1950 PSI (134 BAR) causing the
MCV (Main Control Valve) to shift.
