CAT^® 303E CR Designed for Optimum Performance in Confined Spaces

The new Cat® 303E CR mini hydraulic excavator, only 155 cm wide across the blade and having a compact-radius design that limits tail swing to less than 12.7 cm, is an easily transported machine that works efficiently and safely in small spaces and on congested jobsites.

With a maximum operating weight of 3530 kg, the 303E CR expands the Cat mini excavator line and gives buyers more choice in the 2.5-3.5 t size class. The new model’s 23.5 hp Cat C1.3 engine combines with a powerful load-sensing hydraulic system – delivering flows to 87.6 l/min – to provide productive, reliable performance in demanding applications.

Available both in cab and canopy configurations, the 303E CR is designed for the operator’s convenience and safety.

A float function for the dozer blade allows the blade to follow ground contour and create smooth finish grades. When digging in confined spaces, the 303E CR’s offset boom provides added flexibility. A mechanical quick coupler is available for accommodating work tools such as augers and hydraulic hammers, and a thumb-ready stick is standard.

The 303E CR’s hydraulic system uses low-effort, pilot-operated joysticks that provide more precise, more consistent control than mechanical-linkage controls. For operator convenience, auxiliary-hydraulic controls are integrated into the joysticks, making the 303E CR work-tool ready with both a one-way-flow circuit for tools such as hydraulic hammers and a two-way-flow circuit when using work tools with cylinders or bi-directional motors. An in-cab pattern changer allows easily switching controls to suit operator preference.

Steel tracks are available for the 303E CR, as an alternative to the standard rubber tracks, for use in applications that require higher resistance to sharp debris.
