CASE Construction Equipment ’s new 580 and 590 Super R series 3 backhoes are built to combine stability in all terrains, with a choice of either mechanical PowerShuttle or PowerShift transmission.
Both the 580SR and 590SR are equipped with a 4.5 litre turbo engine. The 580SR is fitted with a Tier 3 engine rated at 72kW (95 Hp), while the 590 model is powered by an electronically-controlled engine rated at 82kW (110 Hp) and provides a torque boost of 516Nm to pull through any difficult conditions.
The hydraulics have been designed with ease of serviceability in mind, with three pressure control checks now grouped together, making an easier and more immediate diagnosis possible in any situation.
Ease of service also extends to daily maintenance, with a tilting hood providing easy engine access from ground level. Sight gauges allow for easy and quick daily checks of hydraulic oil and coolant levels. Along with this, the electronically controlled engine is compatible with the Case EST (Electronic Service Tool) for rapid diagnosis and minimum downtime.
When used effectively, EST can halve the time taken to diagnose and rectify a performance incident. One of the main benefits is being able to isolate troublesome and intermittent incidents by monitoring the operation of particular circuits or sensors of interest for faults during machine operation. The EST also assists the Case service technician to locate the relevant component using screen images.
Operator comfort was also considered in the re-design, with the electronic foot and hand throttle and one touch idle control simplifying operation.
The cab features good all round visibility with floor-to-roof glass. The ergonomically placed controls ensure the operator can easily concentrate on the job at hand and low noise levels ensure comfortable operation.
