normal operating conditions. Under adverse
conditions, allow more room for safe operation.
On jobs on which minimum distance between
machines is specified for the haul road, be
sure to observe the regulations at all times.
Such regulations would be established for the
safety of everyone on the job(refer to g.5-10).
Pay attention to haul road conditions to
avoid rocks, holes, or other obstacles. Such
obstacles not only present hazards to safe
operation, but can needlessly damage tyres
and rides if not avoided(refer to g.5-11).
Be sure to reduce speed and come to a full
stop, as required, at intersections, rail-roads,
public highways etc.. Where a 'FLAGMAN' is
stationed to direct trafc, always stay alert and
follow his directions.
5.4 Dumping
The dumping operation usually depends upon
the type of material being hauled. For instance,
overburden and other waste material is usually
dumped over a spoil bank or piled into large
mounds. The dumping on a job of this type
might be controlled by a dump 'SPOTTER',
'FLAGMAN' or 'BANKSMAN' or second person
who directs the truck to its dumping area. The
'SPOTTER' is needed due to the limited rear
visibility the operator has with a loaded truck of
this size. While backing to dump, the operator
must watch the 'SPOTTER' at all times and
follow his direction. Under no circumstances
should the operator leave his seat to gain
better visibility while backing(refer to g.5-12).
Always remain seated to maintain maximum
machine control(refer to g.5-13).
Mineral ores, blasted rock etc., are usually
dumped into a hopper or crusher where it is
processed before shipment. When dumping
into a hopper, the operator, in order to
avoid excess wear on the tyres, must avoid
hitting the protecting rail at the hopper. If a
DRIVEOVER HOPPER is used, the operator
