Case CE launched its new CX750D, the largest and most powerful machine in the Case excavator range, at Steinexpo: like all D Series excavators, this machine has been built to achieve faster cycle times and to maximise productivity.

An electronically controlled hydraulic pump and larger control and solenoid valves boost breakout forces, increase lifting strength and improve responsiveness. The Case Intelligent Hydraulic System and its four integrated control systems make the best use of the machine’s hydraulic power and momentum, resulting in added strength and fuel efficiency. Operating at 512 horsepower, the CX750D is available in standard configuration with a 335 kN bucket digging force (with Power Boost), and mass excavation configuration with a 366 kN bucket digging force (with Power Boost), and features a shorter boom and arm that allows for greater breakout forces and is capable of handling larger buckets for added capacity.

The boom and arm, as well as the undercarriage, are all more robust to allow for greater power and productivity, and arm and bucket cylinders are larger to help improve performance. And the machine can be operated in one of three operating modes – Automatic, Heavy and Speed Priority – to provide the optimal and most efficient use of hydraulic and engine power. The CX750D achieves Tier 4 Final compliance through an innovative combination of selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) technologies, which helps maximize uptime and performance – all with minimal maintenance. There is no diesel particulate filter (DPF), no DPF regeneration or associated lifetime service costs. This guarantees maximum uptime for our customers.

The reinforced structure of the machine, especially of the retractable undercarriage and front attachment, ensures utmost reliability, even in the toughest and most demanding applications. The CX750D has been developed with the customer in mind. It is extremely reliable and durable and uptime is maximised due to a number of new features. Maintenance and access to the machine are now easier because of the wider catwalks and new guardrails for safety. All filters are grouped in the pump compartment for simplicity and a new standard hydrostatic reversible fan responds to actual cooling demands and reduces power absorption and maintenance.

The new CX750D features an improved cab than previous Case machines in this size class, and offers a fully adjustable workstation with a new high-back seat for optimal comfort and support. Standard rear- and side-view cameras feed a 7-inch widescreen monitor that also provides operators with real-time access to important performance parameters, including fuel consumption, operating hours and machine information. The optional Case maximum view camera, an innovative three camera system, further improve the visibility and safety around the machine.
