48 TRANSPORTING THE EXCAVATOR ON A VEHICLE
TRANSPORTING THE EXCAVATOR ON A VEHICLE
To avoid serious injury or death:
A No directional changes should be made when
the excavator is on the ramp. Should a change
of direction be necessary, drive off the ramp
completely and make the turn.
A When driving forwards or backwards onto the
vehicle, or when swinging the upper body,
make sure that neither the CAB or the gates of
the vehicle will be damaged.
A When the excavator reaches the point between
the ramps and the bed, halt and then move very
slowly until the excavator reaches the
horizontal position.
A Move the excavator onto the vehicle only with
the arm completely pulled in.
A Do not jack up the machine using its boom to
load or unload the excavator from the vehicle.
Doing this is dangerous. Otherwise the CAB of
the vehicle could be damaged when swinging
around the upper body.
A Make sure the ramps are of sufficient capacity
and securely connected to the vehicle to safety
support the machine throughout the loading /
unloading operation.
B Transporting on a Truck
To avoid personal injury or death:
A After loading the machine on the truck, lower
the bucket and dozer onto the truck bed.
Prepare a platform to load or unload the excavator. Take
following steps when using ramps.
1. Apply the parking brakes of the vehicle, and block the
drive wheels from both sides.
2. Use mounting brackets to secure the ramp properly.
Connect the ramps directly with the bed.
