Excavating machinery is divided into 2 basic types:
- wheel models that are easily transportable (independently or joined to a tractor unit through a rigid towbar);
- tracked models that are generally delivered on low loader semi-trailers (though there are special models with tracks of wear-resistant rubber to avoid road surface damaging).
Digging is the major purpose of these vehicles. It is performed primarily by means of buckets. They exist in a variety of size, the choice of which depends on the power capacity of a machine and the soil type. Hydraulic hammers are used if the ground is frozen.
The operating tool of demolition excavators is a nonadjustable bloom with a rope. The important parameters for such units are a steering angle, a radial motion speed and the total weight of an excavator that counterbalances the inertial force of a striking part.
