Caterpillar had confi ned spaces in mind when designing its
303E CR mini hydraulic excavator, which measures just 61
inches across the blade with a 5-inch tail swing. Weighing in at a
maximum 7,782 pounds, the 303E CR features a 23.5-horsepower
Cat C1.3 engine and a load-sensing hydraulic system that delivers
fl ows up to 23.1 gpm.
The hydraulic system uses pilot-operated joysticks for precise,
consistent control, and auxiliary hydraulic controls are integrated
into the joysticks for a one-way-fl ow circuit for tools such as
hammers and a two-way-fl ow circuit for tools with cylinders or
bi-directional motors. The 303E's bucket rotates 200 degrees to
ensure material retention at the top of the lift cycle when loading,
and also allowing for deeper fl at-back trenches without having to
reposition the excavator.
The dozer blade creates smooth fi nish grades via a fl oat func-
tion, and the bucket can be used in a front-shovel confi guration. An
offset boom delivers fl exibility when working in confi ned spaces.
Both cab and canopy confi gurations are available, and all op-
erator stations are ROPS certifi ed. Additional cab features include
a travel alarm, automatic
swing brake, 3-inch-wide
retractable seat belt and
an adjustable suspension
seat.
A mechanical quick
coupler is available for
accommodating attach-
ments, and the 303 CR
accepts all Cat 303.5 and
304E Series mini excavator
work tools. Steel tracks are
available as an option.
