Timber grapples
Working with
grapples

Unloading vehicle

Take great care when filling the grapple
so as not to damage the
load stakes on the bunks of the vehicle.
1 Approach the vehicle which is to be
unloaded with a raised and
fully open grapple.
2 Tilt the grapple forward and lay it
down over the load.
Close the grapple and begin to tilt it
slightly upwards. Then repeat
alternate closing and upward tilting of
the grapple until it is full.
NOTE: Take great care
unloading a vehicle, particularly
when there are only a few logs left. If
the grapple should grip
round the far edge of the platform
this could lead to damage.
Loading vehicle using timber
grapples
1 Make sure that each log lies correctly
in the grapple in order to
avoid "crows nests".
2 While approaching the vehicle, which
is to be loaded, raise the
grapple so that the logs clear the
stakes.
3 Lower the grapple to a level position
onto the bunks or platform
and place the bundle against the stakes
on the far side.
4 Open the grapple fully and carefully
reverse.

Stacking

On machines with Boom Suspension
System it is recommended
that speed-dependent position
selected. The precision increases and
the risk of "crows nests" is reduced.
NOTE: Do not use floating position
when handling timber.
1 Keep the grapple as near the stack as
possible to prevent logs
falling down.
2 Tilt the grapple slightly forward.
3 Carefully open the clamping arm fully
so that the logs can roll out of the
grapple.
4 Reverse carefully and at the same
time lower the grapple and hold it close
to the load to prevent logs from falling.
• When using a grapple with heel/kick-
out, there is no need to tilt the grapple
forward. The lifting height of the
machine is better utilised and one can
build higher stacks. The heel kick-out
can also be used as a counter hold
when handling single logs.
Basic rule: Make sure that the logs
leave the grapple without falling.
