Cat is launching five new mini hydraulic excavators which it says are designed to provide users the best performance, versatility, safety, operator convenience and affordability in the smallest possible packages for 1-to-2-ton class machines. The company says their customer-centred approach to engineering has resulted in the new models incorporating industry-first standard features, such as joystick steering (stick steer) and a tilt-up canopy or cab, as well as new options, including air conditioning and expandable undercarriages across the range.
The new model range allows customers expanded choices for matching machine capabilities and machine features to the applications: 301.5 (1.5-ton class, standard tail swing, with canopy); 301.6 (1.5-ton class, standard tail swing, with cab); 301.7 CR (1.7-ton class, compact radius, with canopy); 301.8 (1.8-ton class, standard tail swing, with either canopy or cab); 302 CR (2.0-ton class, compact radius, with either canopy or cab).
Approximate minimum operating weights for the new models range from 1,575-2,045 kg, with weights increasing to 1760-2200 kg, depending on specific machine configuration. Dig depths are 2340 or 2370 mm, depending on the model, and an available long stick increases depth to 2,540 or 2,570 mm. Rubber track undercarriages are standard, with steel tracks available for all models.
All the new models use the Cat C1.1 engine, a three-cylinder diesel rated at 14.3 net kW (19.2 net hp), available in configurations that meet EU Stage V emission standards as well as the requirements of less regulated countries. The C1.1 features a power-dense design and delivers consistent performance through a wide speed range. Fuel efficiency is enhanced with engine idle control and automatic shutdown systems.
Responding to our questions about its activities with electric vehicles Cat confirmed that it too is developing electric drives: “The Cat 300.9D VPS mini excavator in our range offers a dual mode selection with a choice of diesel or electric power,” it says. “In addition, our development projects do include electric drive for mini excavators.”
