Introduction

The HC300 is a public works hydraulic excavator comprising various sub-assemblies each having a particular role. It carries the track assembly composed of D8 type triple ribbed pads of 24" and 34" width. The assembly is supported by 1 upper roller and 7 lower rollers. These rollers are sealed for life (see drawing page 7)

Each track is independent of the other and is driven by a hydraulic motor through planetary reduction gear (see drawing page 4). The 2,400 c.c. motor develops a torque of 1,150 m.kg. at 300 bars. The reduction gear incorporating two reductions of 16/34 and 18/50 result in a sprocket wheel torque of 9,250 m.kg.
