Dumping
When dumping the operator should steer the vehicle ensuring that it is straight
and with the load on level ground. 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. 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. Always remain seated to
maintain maximum machine control.
Mineral ores, blasted rock etc., are usually dumped into a hopper, or crusher,
where it is processed. 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 must avoid rubbing the
tyre inner sidewalls.
When hauling dirt or rock from a borrow pit into a fill area such as an earth-fill
dam, the load is usually dumped in a string with other loads and the loads
smoothed out with a crawler tractor. When dumping on a fill of this type, the
operator usually works alone and picks his own dumping place. To save
bulldozer work and cleaning up, the load should be dumped as close as possible
to the preceding load. The operator should pull past the preceding load, turn in
line with the string and back his truck until it is within a few feet of the last load.
This assures that the load will fall in the right place. No matter what kind of job
the operator is working, there are a few things which are common to all jobs and
which the operator should observe -
When dumping over a spoil bank without a 'SPOTTER', know how close the
machine can safely approach the edge under all weather conditions. If in doubt
as to dumping safety, dump the load a safe distance from the edge so that it
can be pushed over the edge later.
