When regular rock dumps are not available, it may
be necessary to haul large rocks in a dump body not
designed for this purpose. The bed of the dump truck
should then be lined with wooden planking so as not to
damage the bed while the rock is being loaded. The
tailgate should be latched again at the bottom but pushed
out at the top, as shown in figure 7-39.
Before hauling asphalt, coat the inside of the bed
with diesel fuel. The fuel prevents the asphalt from
sticking to the dump bed. To control any rapid heat loss,
cover the hot-mix with a tarpaulin that should be tied
down securely to prevent flapping in the wind.
NOTE: Some states and countries require that all
loose materials hauled in dump trucks must be covered
to prevent spillage on roadways and breaking of vehicle
windshields. Know the rules and regulations for the area
you are to operate in.
Figure 7-43.Avoid backing accidents; use a backing guide.
When performing dumping operations, be careful
of overhead obstructions, as shown in figure 7-42.
Ensure the dump bed is completely lowered before
proceeding. When backing, use a backing guide to
avoid a backing accident similar to the one shown in
