Major manufacturers are introducing versatile new utility machines as well as technologies that will reduce running costs for users, as well as boosting productivity. Smart control systems are being launched, while a number of key partnerships are also being seen for the compact machine segment.
Wheeled excavators are highly versatile machines that can be equipped with an array of tools and attachments to handle a wide range of applications. These units have traditionally been popular in Europe but are now being sold in other international markets also.
One key development for this segment comes in the shape of a partnership between Case CE and Hyundai Construction Equipment. The two firms have jointly launched a four-model E-Series wheeled excavator range. A fifth larger model will be introduced in the future.
The wheeled excavator line-up includes the conventional tail swing WX140E and WX160E, along with the short radius WX155E SR and the WX175E SR. The conventional tail swing WX210E will be launched at a later stage.
Features of the machines include Bosch Rexroth Load Independent Flow Sharing hydraulic systems on the four smaller models as well as heavy-duty ZF axles and hydrostatic transmissions. Enhanced site safety is thanks to a large operator cab with CASE Maximum View Monitor enabling 360° view cameras and additional rear radar.
The units operate on a range of bio fuels and synthetic fuels thanks to Cummins Stage V diesels, with no requirement for exhaust gas recirculation (EGR). The four machines have Stage V compliant Cummins B4.5 diesels rated at 129kW while the WX210 E will have the Cummins B6.7 diesel delivering 145kW.
The machines will be available with several combinations of front and rear dozer blades plus front and rear outriggers. Upper equipment will comprise a choice of mono or two-piece main booms except the WX175E SR which will have a two-piece articulating boom only
Meanwhile, Hitachi Construction Machinery (Europe) NV (HCME) is now offering its smallest wheeled excavator, the ZX95W-7. The machine is said to be compact and agile, with impressive lifting capacity. Well-suited to use on urban jobsites, the machine shares proven technology and features with other Hitachi Zaxis-7 excavators that are said to optimise productivity, comfort, safety and uptime.
The machine can be used on a wide range of projects, including road and general construction. The compact size and short turning radius allow the machine to work efficiently and safely in confined areas in the vicinity of pedestrians and road users. Adding the two-piece boom, in combination with the swing boom, further boosts adptability.
The ZX95W-7 is said to be manoeuvrable due to the four-wheel steering while its high lifting capacity helps boost productivity. Versatility is further improved when used with a tiltrotator and S-type couplers for attachments.
The cab is said to offer high comfort with good ergonomics and all-round visibility. Ease of use is claimed for the controls while visibility is boosted by the rear-view camera.
Stability is provided by the blade positioned on the rear of the undercarriage, and by the optional outriggers for left and right sides. Options also include the choice of single or twin tyres.
Uptime is said to be maximised and good access to the engine compartment makes inspections quick and convenient. Downtime is minimised by the priority given to easy maintenance and cleaning.
The new Wacker Neuson EW100 wheeled excavator benefits from sophisticated features such as an intelligent attachment management system, as well as the capability to use diverse operator assistance systems.
When changing attachments, the machine assists the operator by adjusting the hydraulic oil flow to the preset tool according to the selection made on the touchscreen display. The excavator is said to offer good visibility due to the low profile engine hood. In addition to the rear-view camera, this ensures a comprehensive view all around the machine. Safety is said to be maximised as the excavator is stable even when rotating 360° with a lifted load. Benefiting from powerful drive hydraulics and a high basic work performance, the EW100 can be used to complete tasks which would otherwise require a 14tonne class excavator according to the firm.at dealers as an upgrade kit.
