Commencement of operation K53a-uk/K53c-uk
The K53a-uk and K53c-uk box rotators can be equipped with a fourth fork (top fork), in order to rotate boxes without
bottom part/silts. The depth of the boxes should be 1200mm at most, so it will always support the top of the box.
1.
Remove the clamping strip (8).
2.
Remove the forks from the forklift truck or forklift mast.
3.
Make sure the fork carrier is straight and clean.
4.
Place the box rotator onto the fork carrier of the forklift truck or forklift mast.
5.
Make sure the locking cam slots into the recess in the centre of the fork carrier. If no recess is available:
a)
Grind such a recess, or
b)
Grind the locking cam from the box rotator and attach a sound locking cam on the spot of an existing recess
in the fork carrier. In doing so, make sure the box rotator sits secure in the centre in front of the fork carrier,
so it is unable to slide sideways.
6.
Attach the clamping strip (8) using two bolts M16x60. Secure these bolts tight! (140 Nm).
7.
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.
8.
Connect the hydraulic hoses to the dual-action connection on the fork carrier.
9.
Remove the check nuts in the lower plate of the fork carrier of the box rotator. Suspend the forks to the fork
carrier and attach the check nuts.
10.
Adjust the plug in fork (10), depending on the width of the boxes to be rotated.
11.
Secure the plug in fork using the lock pin (11).
12.
Adjust the topfork (12) to the desired position, depending on the level of the boxes to be rotated.
13.
Keep about 50mm of space between the top of the box and the bottom of the fork if the box has been lifted
a little from the ground.
14.
The fork positioner of the top fork must reach at least 150mm into the slot.
15.
Secure the top fork using the pressure bolts; tightly secure first the bolts and then the lock nuts (140Nm).
16.
Remove the locking pin (7) at the back of the rotating cylinder before you start rotating. Place the pin into
the ring on the back plate, so it will not get lost.
17.
Subsequently check that the hydraulic hoses can move freely and check that the system is not leaking oil.
18.
Check the correct operation of the box rotator by controlling the hydraulic functions.
The WIFO box rotator is now ready to be used.
