Case Construction Equipment has introduced the CX145D SR minimum-swing radius excavator to its D Series lineup.

The CX145D SR features a compact counterweight and modified boom placement, and the company says it is designed to provide ample digging and lifting power in a small footprint. This, Case says, results in a highly maneuverable and powerful excavator that is easy to transport and ideal for restricted jobsite conditions, such as landscape applications, utilities, bridge work and urban construction.

The CX145D SR offers bucket digging forces up to 21,400 foot-pounds and lift capabilities up to 21,350 pounds, and it boasts an operating weight of 32,100 pounds and a 102 HP Tier 4 Final engine. Other CX145D SR options include a dozer blade configuration as well as the choice between either steel or rubber tracks, depending on operating conditions and requirements of the jobsite.

Case says that each D Series model is built to provide significant operational gains, which includes faster cycle times, greater fuel efficiency and improved responsiveness. The company says that lifting capacities are increased and responsiveness is improved because of the electronically controlled hydraulic pump and larger control and solenoid valves.

Offering more standard features than previous Case excavators, the company says, D Series models simplify the buying process and make them extremely versatile and operator friendly.

The CX145D SR excavator meets Tier 4 Final emissions standards through an innovative combination of selective catalytic reduction (SCR), diesel oxidation catalyst (DOC) and cooled gas exhaust recirculation (CEGR). There is no diesel particulate filter (DPF) and no DPF regeneration or associated lifetime service costs.

By using a new electronically controlled pump, multiple sensors and a larger control valve, the company says a faster cycle time is achieved. These features, Case says, enhance the Case Intelligent Hydraulic System and its four integrated control systems to make the best use of the machine’s hydraulic momentum and power. This, the company says, results in added strength and fuel efficiency.

There are four systems that make up the Case Intelligent Hydraulic System: 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; Boom Economy Control (BEC), which reduces RPMs by using gravity during boom down and swing; and Spool Stroke Control (SSC), which adjusts hydraulic pressure during digs.

The company says that the Case Intelligent Hydraulic System actively manages hydraulic power throughout lift/dump and dig/curl movements to maximize speed and efficiency while reducing fuel consumption by minimizing unnecessary hydraulic flow.

The Auto Power Boost feature has three power modes that the company says maximizes machine performance and fuel economy:

  • Automatic (A): The best balance between productivity and fuel efficiency
  • Heavy Duty (HD): High workload mode
  • Speed Priority (SP): Extra speed and power for the most demanding jobs that require maximum productivity

Case says that the D Series excavators now offer more standard features than any previous Case crawler excavator. These features include Free Swing for improved craning, lifting of offset loads and laying; an easy pattern selector for the operator’s preference of ISO or SAE controls; and oil sample ports for quick sampling of engine and hydraulic oils.

Also featuring an industry-leading operator environment, Case says the CX145D SR features a more spacious cab, a standard fully-adjustable heated air-ride seat, excellent visibility, a pressurized, viscous-mounted cab that reduces noise and vibration and ergonomic multifunctional controls.

The CX145D SR also features a Bluetooth radio and standard rear-view and side-view cameras that feed a 7-inch widescreen monitor. The Case Max View Monitor is optional and provides 270-degree visibility, which the company says improves jobsite safety and provides the operator full visibility of the machine’s surroundings.

Every D Series machine is also available with a new LED working light package that can provide illumination three times brighter than halogen, which the company says allows contractors to work around the clock. This LED package includes six LED lights with two in the front, two in the rear and one on each side.

All Case D Series excavators are covered by the Case ProCare, which includes a three-year Advanced Case SiteWatch telematics subscription, a three-year/3,000-hour full-machine factory warranty and a three-year/3,000-hour planned maintenance contract.
