Compact radius for new Cat excavator

10 Oct 13 Caterpillar has come to market with a new 17-tonne E-series tracked excavator that meets the Stage IIIB emissions standards.

The new Cat 314E L CR hydraulic excavator has a compact radius design that keeps the upper structure completely within the machine's footprint. When slewing, there is limited over-side extension.

The Cat C4.4 ACERT engine powering the 314E L CR develops 91 net horsepower (67 kW) and can use either ultra-low-sulphur diesel fuel (ULSD) or a bio-fuel blend of ULSD and up to 20% bio-diesel (B20) fuel meeting EN14214 standard. The engine provides two power modes, high and economy, to match operating situations with efficient fuel usage. An On-Demand Engine Power feature keeps engine speed low during light work and idling to conserve fuel but automatically increases speed when loads increase. For added fuel savings, the Engine Idle Management system shuts down the engine after a specified time interval.

The main pumps of the hydraulic system, located side by side, are driven directly from the engine for efficiency, and the electrically-controlled regeneration valve in the boom-down circuit saves fuel and minimizes heat by recycling oil between boom-cylinder ends, Cat says, eliminating the need to pump oil.

A quick coupler is optional, not standard.

Two counterweight options are available, 3.06-tonne and 3.56-tonne. Three types of booms are available: a reach type for all-around versatility, a variable angle boom for more flexibility, and a power offset type for added production in restricted spaces.  Depending on the boom choices, different stick options are available.

There is also the option of the Cat Grade Control Depth and Slope system, which allows operators to cut and fill to specification more quickly.
