5 WORKING THE TRUCK
5.1 Working the Truck
Mining Dump trucks are used on a variety of
hauling jobs, from mine overburden removal
to dam building. Every truck operation,
regardless of the type of job, can be divided
into four phases; loading, hauling, dumping
and the empty return.
Note:
After coming to a stop for loading or
unloading the truck, the Parking-Emergency
Brake control can be pushed in to hold the
brakes in the applied position as though the
foot brake is depressed. (see Fig 5-1).
5.2 Loading
The most common methods of loading trucks
are with hydraulic excavators, rope shovels,
and front end loaders. For maximum material
movement, the truck operator must help the
loading machine operator hold loading time to
a minimum. The fewer manoeuvres the truck
must make to get into loading position, the
sooner loading can start. And the shorter the
distance the loading unit bucket must travel
between the cut, or stockpile and the truck
body, the more passes it can make in a given
period of time and the quicker the truck can be
loaded.
