Stow the boom and lock the turntable as indicated above for travel
operation. Secure the hook block to the front pintle.
Tow the crane from the rear using the specified military tow bar. Attach
appropriate flags and/or lights to the overhanging boom. Tow with a
vehicle with sufficient braking and tractive effort to control the towed
Do not allow a passenger to ride in the crane cab while being towed.
Reduce crane tire pressure to 65 psi.
Check crane stability before lifting loads. Ensure the outriggers (or tires if
lifting on rubber) are firmly positioned on solid surfaces. Ensure the crane is
level, brakes are set, and the load is properly rigged and attached to the hook.
Lift the load slightly off the ground and recheck the stability before proceeding
with the lift. Determine the weight of the load before you attempt the lift.
Check the Rated Lifting Capacity Chart (see pages 1-3 through 1-6) against
the weight of the load.
Most accidents involving mobile hydraulic cranes are caused by the following:
- crane out of level,
- bad surface conditions,
- outriggers used improperly or not used at all,
- inadequate blocking under outrigger floats,
- improper crane operation.
