12.5.7 Enlarging the load-bearing area
If the surface of the outrigger pads is too small, you must enlarge the load-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.
H
If the truck crane is equipped with plastic outrigger pads then the uppermost layer
of the packing must be a steel plate (1) of sufficient strength.
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 causing the
truck crane to overturn.
S
Risk of damage to the outrigger pads!
Always place a steel plate of sufficient strength as the uppermost layer of the
packing if the truck crane is equipped with plastic outrigger pads. This prevents
the outrigger pads being damaged due to one-sided pressure.
