Locking/unlocking the auxiliary hoist
Auxiliary hoist
safety valve
The hydraulic cylinders of the locking pins are blocked with a safety valve.
The valve is located on the rear right-hand side of the auxiliary hoist, at the
same height as the treadle.
Closing the valve
Always close the valve after you have locked
the auxiliary hoist on the 15 t base plate.
•
Close the valve – handle (
1
) at right angles to
the line.
The pins are secured against accidental activa-
tion.
Opening the valve
Before the locking pins are extended or
retracted, you have to open the safety valve.
•
Open the valve – handle (
1
) parallel to the
line.
The pins can now be moved using the hand-
held control.
•
Close the valve after extending the pins.
G
Risk of accident when the safety valve is open
Always close the safety valve when the auxiliary hoist on the 15 t base plate
is locked. This prevents the auxiliary hoist from being unlocked due to unin-
tentional actuation and from being lifted off the base plate.
