Winching out
Oil in at V2.
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 K leads oil to the Over
Centre Valve L. This valve opens at
approximately 70 bar so that oil from
the motor can return to the tank.
The oil ows to all motors M1-3 and
passes through Over Centre Valve L
and out through V1.
(Red lines in the circuit diagrams = oil ow. Green lines = only pressure).
