The walking excavators' special features are based on a sophisticated high-tech chassis and the patented boom: various hydraulic cylinders enable the all-rounder to adapt its wheels and support to any terrain. For this, in some countries, the excavator is also called a spider excavator.
Fixed tilting edges on tracked excavators can be adjusted depending on the task ahead thanks to the adjustable wheel and claw supports.
As a result, it produces lifting and ripping forces beyond those of conventional excavators. A spider excavator weighing 9.5 tons produces an output similar to that of a 20-ton tracked excavator.
