CAT 1.7T Excavator
Caterpillar Introduces 1.7 tonne D Series Compact Radius Hydraulic Excavator
The powerful, versatile, zero tail-swing 301.7D CR mini-excavator is ideally suited to working in restricted work areas and is the latest addition to the expanding range of Cat® mini excavators which feature powerful hydraulics and excellent service features.
Productivity in Confined Areas
The zero tail swing Cat® 301.7D CR can work comfortably in confined work areas with the machine upper frame able to slew within its track width. Fitted with an extending undercarriage as standard, the machine can gain access into most areas when fully retracted to 990mm (3′ 3″) wide and once extended to its full 1300mm (4′ 3″) working width, the undercarriage affords excellent stability for even greater digging and loading performance.
The 301.7D CR can be specified with either standard or optional long stick giving an additional 140mm (5.5″) dig depth, an extra 114mm (4.4″) load height and 153mm (6″) more reach at ground level. With both options, two-way auxiliary hydraulics allow the operation of a hydraulic hammer and of a bi-directional tool such as an auger. The optional second hydraulic function is operated by a proportional roller on the left-hand joystick. This option includes a switch that allows the operator to vary the auxiliary hydraulic flow to suit each individual work tool.
