The Cat range of Next Generation mini hydraulic excavators has been expanded with the addition of two new models in the 7-to-10-ton category. The new models provide a selection of basic configurations, allowing customers to choose the machine that works most efficiently in applications
routinely encountered. As with all Cat mini excavators, the new models feature heavy duty main structures, fuel efficient engines, load sensing hydraulics, spacious cabs, and the exclusive Caterpillar stick steer system. The overall design goal for these models is to ensure optimum value for
the customer in terms of performance, operator experience, serviceability, and affordability.
The new 307.5 weighs from 7 532 kg to 8 233 kg depending upon configuration. It is a standard tail swing model with a fixed boom, powered by a Cat C2.4 turbo diesel engine rated at 41.7 net kW. It can be ordered with a standard stick delivering a 4 107 mm dig depth or a long stick that
increases the depth by approximately 560mm.
Also new to the range is a 310 weighing between 9 601 kg to 10 182kg, and featuring a fixed boom, standard tail swing, and twin blade cylinders for handling heavy duty dozing chores.
This machine uses the Cat C3.3 diesel engine rated at 52.4 net kW (70.3 net hp) and has a dig depth of 5174mm. Intuitive controls include a LCD monitor that provides easyto-read machine information and features a jog-dial for easy navigation, including setting personal operating preferences.
For added convenience, a standard control-pattern changer
allows operators to quickly adapt the machine to their favoured
joystick movement. A machine security system is standard,
available as key with passcode or push-to-start with fob. The
machine can also be Bluetooth-enabled through the radio.
