(2) Maximum Gradient
The maximum gradient - X - (Figure 2.2) permissible for this machine is 20% (11º, 1 in 5) Do not
attempt to exceed the machines gradient capabilities.
It should be noted that adverse ground conditions will limit the machine’s gradient capabilities.
Figure 2.2 - Maximum Gradient
(3) Crossing a Slope
Muddy, slippy ground conditions will adversely affect the ascending and descending capabilities
of the dumper.
However, these ground conditions can be even more hazardous when crossing a slope. Greater
care must be taken when crossing sloping ground to prevent the machine sliding sideways out
of the operators control.
The maximum slope - Y - (Figure 3.3 Crossing a Slope) is 20% (11º, 1 in 5). Do not attempt to
exceed this figure.

2.16 Responsibilities
Site management must identify possible dangers and make arrangements to eliminate them.
Site management are responsible for planning driveways around the site which will prevent the
