Wheel excavator moves easily, and mainly for some small
project in the city, cannot be used in very soft ground. Crawler excavator
cannot move on the road, but can work in some muddy ground, and will not be
trapped. Crawler excavator’s machine body is bigger and work efficiency is
higher than wheel excavator.
Advantages: Efficient for large contact ground area, muddy
construction sites, wet lands and other area that easily get stuck; crawler
excavator’s comparative heavy self-weight makes it go various more extensive areas;
for the crawler belt made of medal ware, the crawler excavator is also
qualified to work in those inadequate operating conditions.
Disadvantages: Comparatively speaking, crawler excavator needs
more investment, and its movability is not that good with the fastest designing
speed being 5-7KM/H, and long distance movement can only depend on dray.
Wheel excavator:
Advantages: less investment, faster speed with normally
40-50KM/H.
Disadvantages: narrow using range, mostly used in road and city
engineering projects. It cannot be operated in mines or muddy wet terrain, and
the climbing ability is not very good. So for now, most customers are tend to
choose crawler excavators.
