Stabilizing Slides Using a Spider Excavator

Spider Excavator - The conventional track excavator is a common workhorse in the logging industry of BC. On steeper ground the operator needs to bench into the slope to gain access and help insure user safety. However, this is not always desirable when we are concerned with stability of a slope since it may lead to costly problems related to placement of the excavated material and other problems such as a loss of toe support and over steepened cut and fill faces.
As an alternative, the Spider Excavator is a machine that has the ability to walk, (like a spider), with its 4 legs on steep slopes of up to 100% without the requirement to construct large benches or create undue ground disturbance. The only effect is the ground compaction at each of the pads on the base of the spiders "legs".
