Leading construction manufacturer Case has launched a four-model E-Series wheeled excavator range, the conventional tail swing WX140E and WX160E and the short radius WX155E SR and the WX175E SR, with a fifth, larger model – the conventional tail swing WX210E – joining the series in the future. The machines will be built under an existing supply agreement with South Korean manufacturer Hyundai Construction Equipment.

The four new models offer smooth operation and maximum control, thanks to proven Bosch Rexroth load independent flow sharing hydraulic systems, and promise durability, reliability and efficient roading capability due to the heavy-duty ZF axles and hydrostatic transmissions, according to a spokesman for the company.

The wheeled excavator range has a large operator cab with the optional Case Maximum View Monitor that enables 360-degree-view cameras and a rear-mounted radar for maximum visibility and safety.

The machines operate on a range of biodiesels, hydrotreated vegetable oils (HVO) and other synthetic fuels and is powered by Cummins Stage V diesel engines.  The four smaller models will use a Cummins B4.5 engine, delivering a maximum power of 129 kW, while the WX210E will come with the larger B6.7, offering up to 145 kW maximum power.

“The engines feature a highly efficient exhaust aftertreatment module, incorporating a diesel oxidation catalyst (DOC), selective catalytic reduction (SCR) and a diesel particulate filter (DPF). With no need for a complex exhaust gas recirculation (EGR) system to comply with Stage V requirements, the maintenance cost is much reduced. In addition, fuel filter service intervals are 1,000 hours and engine oil and filter intervals are set at 800 hours, further maximising machine uptime for the operator,” the spokesman says.

The new Case E-Series wheeled excavators boast proven well-established quality components. They will be available in a range of lower frame layouts, with several combinations of front and rear dozer blades plus front and rear outriggers.

Upper equipment comprises a choice of mono or two-piece main booms for all machines except the WX175E SR, which is supplied with a two-piece articulating boom only. Standard cruise control will make travel between work sites easier while moving material in a work site is made more efficient by the optional ride control and even more so by using joystick steering controls, he says.

Operators can also benefit from an optional automatic digging brake and a fine swing control, to further ease control of the machine’s movements. An auto safety lock, similar to the system found on the Case ESeries crawler models, prevents unwanted movement of the machine’s upper structure when the gate lock is released.

The E-Series cab features a telescopic steering column with two tilt points, to make it easier for operators of all sizes to find a comfortable driving position. The windscreen has parallel wipers in both the upper and lower sections for the widest possible coverage and the machines can be supplied with an optional rearview camera on the right-hand side. 

Six LED work lights are standard, further improving visibility in poor light conditions. An 8-inch touchscreen monitor provides access to a menu system that controls all functions of the machine. A secondary screen is available for cameras. The operator can navigate the main screen through a jog-dial controller, that also controls the engine throttle. This jog-dial has 10 engine rpm positions.

The monitor provides ECO guidance for the operator, showing a range of data including idle times to help the drivers to improve their performance and productivity while working. Proportional joystick controls are standard, with a forward/reverse selection switch in the lever head. The lever also contains a front axle oscillation lock and a detent feature. Joystick steering is optional, as is a smart key with push-button start.

Case Construction Equipment, a brand of CNH Industrial, sells and supports a full line of construction equipment around the world, including leading loader/backhoes, excavators, motor graders, wheel loaders, vibratory compaction rollers, crawler dozers, skid steers, compact track loaders and rough-terrain forklifts.
