12.6.8 Enlarging the load-bearing area
If the surface of the outrigger pads is too small, you must enlarge the
ground bearing area by packing the outrigger pads;
à Determining the
required load-bearing area
, p. 12 - 9.
For packing, use only suitable materials that will withstand the outrigger
pressure, e.g. straight hardwood of similar cross-sections or steel plates
with welded-on strips that will keep the outrigger pads in position.
Level the packing; the outrigger pad must not
be at an angle.
Ensure that the outrigger pressure is evenly
distributed over the packing:
– The outrigger pad must be positioned in the
centre of the packing.
– The outrigger pad must cover all the
wooden planks.
– If the packing has several layers, each layer
must be placed below the other offset
by 90°.
– The packing must lie flat on the ground.
Consult your supervisor if you are in doubt.
G
Risk of accidents if the packing is insufficient!
Only use materials of sufficient strength.
This will prevent the packing giving way and causing the truck crane to tilt
and overturn.
G
Danger of overturning if the packing or truck crane is at an angle!
Level the packing and the truck crane.
This prevents the outrigger pads slipping off the inclined packing and caus-
ing the truck crane to overturn.
