Caterpillar boosts mini excavator range

Caterpillar has added the conventional configuration 301.7D, 302.2D and 302.4D models to its D-series mini excavator range.

Powered by a three-cylinder 13.2 kW Yanmar diesel engine, when fitted with cabs the new machines have operating weights of 1.9 tonnes, 2.1 tonnes and 2.4 tonnes respectively, or are 110 kg lighter with a canopy.

Bucket breakout is 18.8 kN on the smallest model and 21.8 kN on the 302.4D. Selecting the long stick option adds around 200 mm to the dig depths, taking them to 2,394 mm, 2,678 mm and 2,634 mm respectively.

These figures compare well with JCB’s 8018CTS, 8020CTS and the slightly heavier 8025ZTS, although these are compact/zero tailswing machines. Caterpillar fits the 302.2D with an extending undercarriage (optional on the 301.7D) and a longer dozer blade is an option on both models, while a float function is standard.

Pilot controls (including a proportional roller on the joystick) are standard across the range, as is two-way auxiliary hydraulics, and there are hoisting brackets on the cab roof to speed loading onto a truck. Oil changes and digging-arm linkage greasing intervals are 500 hours and the hydraulic oil can be left for 3,000 hours.
