Caution Of Travel On A Steep Grade - IHI IC75 Operation Manual

Caution of travel on a steep grade

•
Do not travel on grades over 20° in order to
avoid turnover.
•
On steep grades over 9°, travel the machine at
low travel speed and middle or lower engine
speed.
•
If the machine is inclined in the forward
direction by 9°, the slope warning is given.
•
Never change the travel direction on steep
grades or cross such grades. Such operation
may cause turnover or slip. Move down to a flat
ground once and make a detour. Be sure to
drive safely.
•
If an overrun warning is given during traveling,
avoid overrun immediately.
Cautions
Travel in the proper postures shown below.
• Drive the machine with the cabin upper side of a slope
when the body is empty. This posture ensures stable
driving, since the center of gravity is located on the
cabin side.
• Drive the machine with the body upper side of a slope
when the body is full. This posture ensures stable
driving, since the center of gravity is located on the
body side.
• When driving over an obstacle, reduce the speed and
drive safely with care not to turn over.
• Do not accelerate or decelerate the speed or stop
suddenly.
• The engine may stop if the travel lever is pulled fully
while climbing a slope.
When the engine speed lowers, return the travel lever
slightly to reduce the engine load.
