Abstract: The invention as disclosed is configurable for a range of uses, load capacities and sizes. The invention as disclosed is a novel combination of a tracked excavator undercarriage and a cab and loader assembly which rotates. The addition of a tracked excavator undercarriage to a cab and loader assembly which rotates allows for improved access to tight quarters. Operator efficiency is improved as well as visibility during operation. Furthermore, because the cab and loader assembly may be rotated to for material handling in tight quarters, the typical stress and wear on the undercarriage and engine are reduced. The combination of the invention as disclosed with tracks improves access to adverse (muddy or wet) soil conditions as commonly found in construction projects involving installation of underground pipe or material handling through better traction and flotation compared to wheeled loaders.
