Case intros CX145D SR excavator with more power, improved cab
Wayne Grayson | August 22, 2017

Case has expanded its D Series lineup of full-size excavators with the introduction of an updated minimum-swing model, the CX145D SR.

Powered by a 102 horsepower Tier 4 Final (T4F) engine, the CX145D SR has an operating weight of 32,100 pounds and delivers bucket digging forces up to 21,400 lb.-ft. and lift capacities up to 21,350 pounds. Case says the machine’s engine is a maintenance-free T4F solution requiring no diesel particulate filter (DPF) or regeneration. The engine instead implements a combination of selective catalytic reduction (SCR), cooled gas exhaust recirculation (CEGR) and diesel oxidation catalyst (DOC) technologies to meet emission regulations.

Case unveils CX750D: New model design is its largest, most powerful excavator

  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 ...

Case says the machine boasts faster cycle times thanks to improved breakout forces and more lifting strength made possible by a new electronically controlled pump, larger control and solenoid valves and multiple sensors. These upgrades combine with Case’s Intelligent Hydraulic System which is made up of four control systems that work to optimize hydraulic power on the fly.

The IHS is made up of the following systems: Boom Economy Control (cuts RPMs via boom down and swing gravity); Auto Economy Control (cuts RPMs during idle and shuts the engine down from a present idle time; Swing Relief Control (cuts hydraulic power when starting swing); and Spool Stroke Control (changes hydraulic pressure when digging).

Plus, the CD145D SR re-uses hydraulic fluid whenever possible, providing further increases to cycle times. And further efficiency gains are possible if the operator takes advantage of the machines’ three working modes: Speed Priority, Heavy Duty and Automatic.
