Long reach excavators with smart hydraulics

Case Construction Equipment has announced the addition of two long reach crawler models to its D Series excavator lineup.

For deep trenching, sloping, demolition, dredging, digging in sand or gravel pits, or any other jobs that require the performance boost of a longer reach, the CX210D LR and CX250D LR feature an elongated boom and arm.

Both new models are powered by Tier 4 Final engines that employ Selective Catalyst Reduction (SCR), do not require a Diesel Particulate Filter (DPF), and therefore require no regeneration.

Here’s a quick look at specs for each machine.

Beyond the benefit of no regen times, the engines boost fuel efficiency by 9% on the CX210D LR and 14% on the CX250D LR.

Case says operators can expect faster cycle times with these long reach models thanks to a new electronically controlled pump, a larger control valve, and multiple sensors working along with the company’s Intelligent Hydraulic System. The system works to optimize the machine’s hydraulic power and momentum through four integrated control systems:

Boom Economy Control (BEC): Reduces rpm by using gravity during boom down and swing

Auto Economy Control (AEC): Reduces rpm during idle and automatically shuts down the engine after a preset time

Swing Relief Control (SRC): Reduces hydraulic power at swing start

Spool Stroke Control (SSC): Adjusts hydraulic pressure during digs

Improvements to the SSC also allow these excavators to re-use hydraulic fluid whenever possible to improve cycle times and efficiency.

In addition to these hydraulic control modes, operators can select from three working modes:

Speed Priority

Heavy

Automatic

These tailor machine energy to the power needed for the job at hand.

A Free Swing feature comes standard on all D Series excavators and boosts performance in craning, laying, or lifting offset loads. Operators can also switch between ISO and SAE controls using an easy pattern selector.

Inside the pressurized and iso-mounted cab, operators will find:

Best-in-class cab space

Standard Bluetooth radio

Standard rearview camera feed on a 7-inch widescreen monitor

Each D Series excavator includes a three-year Advanced Case SiteWatch telematics subscription, providing real-time data on performance, fuel consumption, operating hours, and more.

Case also offers an optional LED working light package which provides lighting three times brighter than halogen. The package includes six lights and a side-view camera.
