Please note that right and left refer to the orientation
you would have if you were looking from the trailer
hitch towards the front of the unit.
•
The rock valve slewing cylinder (5) has fully
extended
•
High pressure oil (red) continues to flow into
the accumulator circuit until the accumulator
(13) is charged to the pressure cut-off point of
the accumulator hydraulic pump (19). When
the cut-off point is reached, the accumulator
pump reduces the hydraulic oil flow until there
is just enough to maintain the cut-off pressure.
•
The S2 valve (7) has finished sliding. Oil is
now routed from the main hydraulic pump (2)
to the piston side of the right hand differential
cylinder (8B).
•
As the right hand differential cylinder (8B)
moves, rocking oil (orange) reaches the left
end cap of the switching valve (9A). The valve
closes by the pressure applied and the force of
the return spring. This removes the pilot signal
to the left side of the S3 directional control
valve (6).
•
As the right side differential cylinder (8B)
extends, the concrete in the material cylinders
from stage A is forced out into the delivery
pipeline. (Pressure stroke.)
•
The oil from the rod side of the right side
differential cylinder (8B) travels through the
hoses to the rod side of the right hand
differential cylinder (8A), forcing it to retract
which it creates a void in the material cylinder
and concrete begins to flow in to fill that void.
(Suction stroke.)
•
The oil from the piston side of the left hand
differential cylinder (8A) is routed through the
S2 valve (7), and back to tank (1).
