2.2.2 Commissioning the K90 box rotator
Different methods are used to fit the mounting blocks
(2)
and the locking strip plate
(3)
, depending on the
type of fork carrier used.
FEM II fork carrier
1.
Unscrew the FEMII/III mounting block
(2)
bolts and remove the mounting blocks.
2.
Reattach the mounting blocks using the bolts, so that the FEM II is underneath. Tighten the bolts securely
(200Nm).
3.
Unscrew the bolts from the locking strip plate
(3)
and put it in the lowest position with the FEM II cam
pointing down.
4.
Screw the bolts back into the locking plate strip.
5.
Remove the forks from the forklift truck or forklift mast.
6.
Make sure the fork carrier is straight and clean.
7.
Place the forward tipping box rotator on the forklift truck or lifting mast fork carrier.
8.
Make sure the locking strip plate slots into the recess in the centre of the fork carrier. If no recess is
available:
a)
Grind such a recess; or
b)
Take the locking strip plate off the box rotator and attach a good locking cam at the spot
where there is an existing recess in the fork carrier.
In doing so, make sure the box rotator sits securely in the centre in front of the fork carrier, so it is unable to
slide sideways.
9.
Check to make sure the hydraulic hoses are clean before connecting them to the rapid-action couplings to
prevent any debris from entering the hydraulics of the machine.
10.
Depending on the model, the following hydraulic hoses are connected:
a)
Electrically controlled switching valve
Connect the hydraulic supply/discharge hoses to the dual-action connection on the fork carrier.
Install the supplied switch so that the machine driver is able to operate it from his driving position and
cannot confuse it with other controls.
For a safe working environment, avoid situations such as inadvertently starting the machine or not being
able to control it.
Keep an eye on the correct voltage of the lifting device and the valve. The voltage is shown on the coil.
Attach a twin core cable in accordance with the circuit diagram. Include a warning light, fuse and/or plug
socket in the circuit if required.
b)
Four-hose connection
Connect the two pairs of hydraulic supply/discharge hoses to the dual-action connection on the fork carrier.
c)
Sequence valves
Connect one pair of hydraulic supply/discharge hoses to the dual-action connection on the fork carrier.
