CASE Construction Equipment’s CX490D and CX500D crawler excavators are designed for heavy excavation work. The models feature cycle times up to 10% faster than their predecessors, improved responsiveness and multifunctional controls, and greater fuel efficiency. An electronically controlled hydraulic pump and larger control and solenoid valves boost breakout forces, increase lifting strength, and improve responsiveness, according to Case.
Both excavators deliver 362 hp; the CX490D features bucket digging force of 55,500 to 60,700 lb.-ft., while the CX500D features bucket digging force of 64,500 to 70,400 lb.-ft.
The CX500D is a dedicated model for mass excavation and comes with a special heavy-duty attachment coupler, larger bucket cylinders, and optimized kinematics.
Both excavators meet Tier 4 Final emissions standards through a combination of selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) technologies. There is no diesel particulate filter (DPF), and no DPF regeneration or associated lifetime service costs. These technologies are combined with the CASE Intelligent Hydraulic System.
Faster cycle times are achieved through a new electronically controlled pump, a larger control valve, and multiple sensors.
The excavators 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.
Both models are available with an optional hydraulic counterweight removal device for improved on-site safety and efficiency during transportation.
