SRT45 Off-Highway Truck
5-3
Safety, Operation and Maintenance Manual
when entering the loading area to avoid
congestion, and for maximum safety(g.5-7).
The following precautions should be observed
when approaching the loading area and while
being loaded.
Avoid rocks and other shovel spillage that
can needlessly damage tyres or other truck
components. Allow the cleanup machine
sufcient time to clear up such debris.
Do not move the truck into loading position
with the shovel bucket swinging overhead.
Large rocks that might fall from the bucket can
be dangerous to both the truck and operator.
Keep your head and arms inside the cab
during loading to avoid the danger of falling
rocks or other shovel spillage.
When the loader operator signals that the
truck is loaded, sound two blasts on the horn,
release the brakes and shift the transmission
to drive (D). Move out of the loading area
and onto the haul road with the least possible
delay to allow any waiting truck to move into
the loading position as soon as possible(refer
to g.5-8).
5.3 Hauling
While travelling the haul road, always maintain
a safe speed for the haul road conditions and
grades. Never allow the machine to move or
coast with the transmission in 'NEUTRAL'!
When approaching downgrades, select
the proper transmission range and use the
retarder and service brakes as required to
maintain safe descent speed without over-
speeding the engine or gaining excess travel
speed. Generally, the transmission range
required for ascending is also correct for
descending a grade(refer to g.5-9).
Always remain a safe distance behind the
machine ahead, particularly on downgrades.
A good rule-of-thumb to follow is to allow two
(2) truck-lengths between machines for each
15 km/h (10 mile/h) of travel speed under
