Winching in at low speed
Oil in at V1.
The shuttle valve C opens and permits
oil ow to measuring point E and to the
brake F which releases when the
pressure exceeds 30 bar.
The pilot line G leads oil to the Over
Centre Valve D. This valve opens at
approximately 60 bar so that oil from
the motor can return to the tank.
The oil drives the motor M1 and
passes through the Over Centre
Valve D and to V2.
When the oil pressure exceeds approx.
90 bar, the sequence valve H opens
and permits oil ow to all motors.
(Red lines in the circuit diagrams = oil ow. Green lines = only pressure).
