l
If the front wheels are completely lifted off the ground, more load will be shifted from the
rear to the front outriggers. There will be more ground pressure on the front outriggers and
less on the rear outriggers. This situation is ideal for lifting off the side in the midship area
of the vehicle.
Any configuration between the two mentioned above will provide intermediate stability
characteristics.
For most situations, NRC recommends that the steer tires are left on the ground with moderate
ground pressure.
Ensure that ONLY the outrigger feet touch the ground. If any other outrigger parts
touch the ground, the wrecker will become unstable.
Ensure that you are constantly monitoring the outriggers and that they all stay in
contact with the ground at all times.
Should any of the outriggers start to leave the ground, or show an imminent risk of
floating, immediately stop all lifting or winching operations to avoid any risk of
tipping over. Any suspended load should be lowered by retracting the boom or
winching down. DO NOT LOWER THE BOOM as it would move the load away from
the vehicle, increasing the overturning moment and the risk of tipping over.
Before beginning lifting or winching operations again, the operator must ensure
that:
l
The ground and blocking are sound and show no risk of sinking or collapsing.
l
The load has been reduced or re-rigged to reduce overturning moment.
l
The outriggers system has been reconfigured to optimize load distribution on
the outrigger system: more ground pressure is needed on the previously floating
outrigger pad.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN THE WRECKER
TIPPING OVER, WHICH CAN CAUSE PROPERTY DAMAGE, INJURIES OR EVEN
DEATH.
