Packing Refuse (1)
Operator Action
None. MCV (Main Control Valve) shifts automatically.
Hydraulic Sequence
Fluid flows from the MCV (Main Control Valve) to the
case end of the carrier panel cylinders. The
cylinders extend, moving the carrier and packer panels up, packing refuse against the pushout panel.
When the pressure reaches 2150
PSI
(148
BAR), the MCV (Main Control Valve) shifts into neutral
and the packing cycle is completed. As the carrier cylinders apply force to compact refuse, the
pressure of the trapped fluid in the packer cylinders will increase. Should this pressure reach 3800
PSI
(262
BAR), a relief valve will open reducing the pressure by allowing some trapped fluid to escape
and
return to the hydraulic tank.

pact refuse, the pressure of the trapped fluid in the
