New, industry-leading Cat® 301.5, 301.6, 301.7 CR, 301.8 and 302 CR hydraulic excavators launched at events across WA and NSW.
Five new models in the Cat® mini hydraulic excavator lineup, engineered and manufactured by Caterpillar, are designed to provide users with the best performance, versatility, safety, operator convenience – and affordability – in the smallest possible packages for 1-to-2-tonne class machines.
This customer-centered approach to engineering results in the new models incorporating industry-first standard features, such as joystick steering (Stick Steer), a tilt-up canopy or cab, automatic two-speed travel as well as new options, including air conditioning, expandable undercarriages across the range and Bluetooth enabled push-to-start.
The new model range allows customers greater choices for matching machine capabilities and features to applications:
- 5 (1.5-tonne class, standard tail swing, with canopy)
- 6 (1.6-tonne class, standard tail swing, with cab)
- 7 CR (1.7-tonne class, compact radius, with canopy)
- 8 (1.8-tonne class, standard tail swing, with either canopy or cab)
- 302 CR (2.0-tonne class, compact radius, with either canopy or cab)
Minimum operating weights (approximate) for the new models range from 1575 to 2045kg with weights increasing to 1760 to 2200kg depending on specific machine configuration. Standard dig depths are 2340mm to 2370mm depending on the model, and an available long stick increases depth 2540mm or 2570mm). 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 19.2 net horsepower (14.3 kW), and 21.6 gross horsepower (16.1 kW) meeting.
Tier 4 Final/Stage V emissions regulations. The C1.1 features a power-dense design and delivers consistent performance through a wide speed range. The cat C1.1 provides a significant increase in engine power and performance over previous models. Fuel efficiency is enhanced with engine idle control and automatic shutdown systems.
The new Next Generation mini excavators use an efficient, fuel saving, load-sensing hydraulic system with an electronically controlled variable displacement piston pump capable of oil flows to 66 L/min. These flow rates, coupled with high main-relief pressures, provide the new models with the hydraulic capacity to generate high digging and lifting forces, as well as manage high-powered attachments.
The expandable undercarriage (standard for all models) narrows to allow the new machines to enter work sites through restricted access points, then extends to provide a stable work platform.
Each model features a dozer blade that further expands the machine’s capability of the new models which, when combined with stick-steer function allows the machine to handle backfilling and grading tasks with ease.
The design of the new Next Generation mini excavators emphasises comfort, convenience, and operator safety. The cab; standard on the 301.6, and optional on both the 301.8 and 302 CR, is pressurised and sealed to minimise dust intrusion and operator sound levels. It also creates an efficient in-cab cooling environment. The front window slides upward and stores overhead, and large glass areas on the sides and rear of the cab, plus a skylight, provides all around visibility.
Controls are designed to be intuitive, with a pattern changer that allows operators to select their preferred system between Excavator and Backhoe pattern. A machine security system is standard on all models.
The Next Generation models feature an LCD monitor, providing easy-to-read machine info and a jog dial for easy navigation and interaction with the monitor.
Stick Steer – A New Way To Move
An exclusive feature for the new Next Generation models is the standard Stick Steer system built into all models. This allows the operator to control tracks using the left-hand joystick control at the touch of a button.
Stick Steer provides the benefit of less effort combined with improved operator control. Complementing stick-steer functionality is an automatic two-speed travel that significantly speeds up machine positioning and control.
Safety And Service
Protective structures (ROPS, TOPS, and Top Guard—Level I) are designed to promote a safe working environment for operators. All controls are protected via a hydraulic lock out, and boom lights help illuminate the work area. Standard LED lights, front and rear, help to further enhance visibility. The easy-to-transport Next Generation models also feature tie-down points on the track frames to facilitate securing the machine.
Routine maintenance check points are accessible at ground level through the side doors, and the battery is maintenance-free.
Industry Launch Events
The new excavators will be launched at dedicated events in Newcastle, Sydney, Wollongong and Perth from March onwards.
