5.3 Loading & unloading
Make sure that the ramps are strong enough before loading the machine and follow these
procedures:
1)
Apply the truck’s parking brake and place stoppers against its tires.
2)
Fasten the ramps securely to the truck bed so that they will not come off. Set the ramps to an
angle of 15°or less.
3)
Direction of the excavator:
The work device should be placed at the foreside and
directs forward while loading (as the right figure);
and while unloading, place the work device
backward at the rear, and travel backward.
4)
Line up the center of the truck bed with the center of
the machine and the center of the ramps with the
center of the crawlers.
5)
Use the engine accelerograph control lever to reduce
the revs of engine, drive the machine slowly to the
slope, and lower the hoe attachment as much as
possible, making sure it will not hit the truck.
6)
Close the windows and doors of cabin, cover the vent, prevent rain from entering.
5.4 Transportation
Warm up the excavator before loading
& unloading in the cold weather.
Put chain and wire rope over the
lower frame. Do not put the chain and
wire on or through the hydraulic
pipes or hoses.
z
The machine should travel at lowest speed on ramps.
z
Turning while traveling on ramps is very dangerous, and it is forbidden. If you must
do so, turn the machine back to the ground or truck bed, modify the traveling direction,
and then pass the ramps.
z
The intersection of the top of ramps and truck bed is protuberant, pass it carefully.
z
Prevent the possible tip over and injury while the superstructure of excavator is
swinging. Retract, lower arm and swing superstructure slowly to achieve best stability.
