Case Construction Equipment has expanded its D-Series lineup of excavators with the addition of the CX750D, now the largest and most powerful machine in the lineup.

Powered by a 512-horsepower, Tier 4 Final engine requiring no diesel particulate filter (DPF), the CX750D features new designs for the boom, arm and undercarriage along with a larger cab. It also benefits from a number of improvements seen across the D-Series lineup.

This new 750 model will replace the CX700B and the CX800B.

The 750 is available in two configurations:

♦  Standard: This configuration weighs in at 158,300 pounds and, with Power Boost enabled, is capable of 75,090 pounds of digging force.

♦  Mass Excavation (CX750D ME): Has a shorter boom and arm for greater breakout force. Weighs in at 159,600 pounds with same digging force capabilities as standard configuration.

Case says the boom, arm and undercarriage on the 750 have been updated with a “more robust” design to accommodate the machine’s greater power and productivity. The design incorporates new arm and bucket cylinders as well that are larger and add another boost to performance.

Inside the new cab, operators will find a fully-adjustable workstation with a high-back seat. Rear- and side-view cameras come standard and are displayed on a 7-inch widescreen monitor. This monitor also displays real-time performance data including full consumption, operating hours and other machine information.

Like its smaller D-Series siblings, the 750 offers faster cycle times, improved control/responsiveness and greater fuel efficiency than previous excavator generations. The lineup features an electronically controlled hydraulic pump and larger control and solenoid valves for improved breakout forces and more lifting strength.

Operators can select from three operating modes—Automatic, Heavy and Speed Priority—to tailor machine performance to the job at hand.

Case says maintenance has been simplified on the CX750D as well with the addition of wider catwalks, new guardrails and the easier access to filters through grouping in the pump compartment. The machine also features a new hydrostatic reversible fan as a standard feature which responds to cooling demands and reduces power absorption and maintenance.
