Terrain Conditions
All application effects are influenced by
the terrain on which the work is being
done. The most common effects are
described here regardless of the degree of
impact, or the operating condition.
Working on Sidehill
Shifts weight balance to the downhill side
of the machine; this increases the wear
rate on the components on the downhill
side of the machine. This increases wear
on rail sides, roller and idler flanges,
bushing ends, and grouser ends.
Working Downhill
Shifts weight balance forward causing rel-
atively higher wear rate on front track and
carrier rollers. Due to design of track,
working in forward minimizes rate of
bushing and sprocket wear.
Working Uphill
Shifts weight balance to the rear causing
relatively higher wear on rear rollers and
increasing forward drive side sprocket and
bushing wear.
Working on a Crown
The inner components carry heavier loads.
This results in increased wear on inner
links, rollers, idler treads and grouser ends.
In extreme cases, the inner bushing-to-
sprocket contact surfaces also may experi-
ence greater wear.
Working in a Depression
Causes loads to be carried by outer (or
outboard) components, increasing wear
rates on outer links, roller and idler treads,
grouser ends and the outer bushing-
sprocket contact surfaces in extreme cases.
