Five new models in
the Cat mini hydraulic excavator line-up, engineered and manufactured by
Caterpillar, 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.
This
customer-centered approach to engineering results 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).
Minimum operating
weights (approximate) for the new models range from 1575-2045 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 2540 or 2570 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.
