Case Construction Equipment's CX210D LR and CX250D LR crawler excavators provide increased operating performance for deep trenching, sloping, demolition, dredging, digging in sand or gravel pits or any application that requires long-distance bucket reach and precision. Each Long Reach (LR) model features an elongated boom and arm for increased digging capabilities in deep or long-distance digging applications, while providing the same responsiveness and multifunction controls of the D Series.
The CX210D LR and CX250D LR both employ an SCR Tier 4 Final solution that provides greater fuel efficiency (CX210D LR – up to 9%, CX250D LR – up to 14%) without sacrificing power. SCR lets the engine run at peak performance throughout the work cycle and, because it works without a diesel particulate filter (DPF), there’s no DPF regeneration or associated lifetime service costs. This helps maximize uptime and performance – all with minimal maintenance.
Faster cycle times are achieved through a new electronically controlled pump, a larger control valve and multiple sensors. These features combine with the CASE Intelligent Hydraulic System and its four integrated control systems to make the best use of the machine’s hydraulic power and momentum, resulting in added strength and fuel efficiency.
The four systems that make up the CASE Intelligent Hydraulic System are: Boom Economy Control (BEC), which reduces RPMs by using gravity during boom down and swing; Auto Economy Control (AEC), which lowers RPMs during idle and automatically shuts down the engine after a preset idle time; Swing Relief Control (SWC), which reduces hydraulic power at the swing start; and Spool Stroke Control (SSC), which adjusts hydraulic pressure during digs.
Using improvements to the Spool Stroke Control system, the CX210D LR and CX250D LR excavators re-use hydraulic fluid whenever possible to automatically increase cycle times and efficiency. The operator experiences a more productive machine without losing the precision of the machine’s controls.
The CX210D LR and CX250D LR excavators also provide the operator with three working modes – Speed Priority, Heavy and Automatic – that help the machine conserve energy and exert only as much power as needed to complete the job at hand.
