Hitachi Construction Machinery Europe (HCME) is offering its advanced technology on the new ZX530LCH-6 large excavator.  Incorporating the Hitachi technology, specially developed for the Zaxis-6 range, the machine is designed and engineered to meet the demands of large-scale construction projects and quarries.

HCME says that several features enhance the durability of the ZX530LCH-6 in line with its overall goal “to build the ultimate excavator,” including a boom reinforced with thicker plates, and an undercarriage consisting of robust components such as the track link, master pin, idler pedestal and bracket, and upper roller bracket.

Other components include the in-cab console, made of weather-resistant AES-grade resin to prevent damage from UV rays, and the upper structure, which has high-quality sealant (around the cooling package) and acoustic materials to eliminate any deterioration caused by heat.

“HIOS IIIB technology developed by Hitachi uses two pumps and control valves to reduce fuel consumption and cut costs. The ZX530LCH-6 can save up to 5% fuel in ECO mode, with the same productivity as the previous model,” says the company.

“This hydraulic technology also has a positive impact on productivity, due to the efficient swing, boom lowering, arm and bucket roll-out.”

Further advanced technology is the aftertreatment device that results in fewer emissions and a quieter performance. It consists of a diesel oxidation catalyst, urea mixing pipe, SCR (selective catalytic reduction) system and silencer.

Attachments for carrying out different tasks can be easily fitted to the ZX530LCH-6 using the attachment replacement support system, and an electronically-controlled pressure adjustment feature also protects the attachments during installation.

Burkhard Janssen, general manager of the Product Management and Engineering Department at HCME, says: “The ZX530LCH-6 offers a comfortable working environment for operators, and is fast and precise, thanks to the efficiency of the hydraulic system. It is renowned for low fuel consumption, as well as high productivity, ensuring a profitable return on investment.”

Meanwhile, Hyundai’s new 49.5tonne HX480 L crawler excavator’s world exhibition debut at the Hillhead exhibition saw “an important innovation” on the new HX range, the new and larger touchscreen monitor. The cluster monitor can display information that mirrors what can be seen on a smartphone, and is 30% larger than previous models. Hyundai’s AAVM (Advanced Around View Monitoring) system for 360° surround virtual operating view also displays on the monitor.

The HX480 L is powered by a Scania DC13 084Ac engine, which complies with the latest emissions standards Stage IV for the reduction of particles and Nox in exhaust gasses, and which is rated at 331kW. Hyundai has chosen a combined solution with EGR and SCR technology.

Hyundai says the HX480 L can offer a reduction in fuel consumption of up to 9%, depending on the type of operation, compared to Hyundai’s 9A-series of machines.

The company’s new 44tonne HX430 L crawler excavator, with a bucket capacity of 1.9m³ and an overall width of 3.34m with 600 mm shoes, made its world debut at Hillhead.

Powering the HX430 L is a Cummins QSL9 4-cycle turbo-charged air cooled diesel engine which also complies with the latest emissions standards Stage IV for the reduction of particles and Nox in exhaust gasses. It is rated at 236kW.

Volvo Construction Equipment, highlighting a number of new excavators and wheeled loaders, says that Raymond Brown Group, Ringwood, county Hampshire, England, has made another substantial investment in 12 new machines from the company. These will be deployed across the company’s construction, aggregates and waste solutions divisions.

Joining the company’s Minerals and Recycling Division are two crawler excavators, a 22tonne EC220E and a 30tonne EC300E, along with two new L120H wheeled loaders and an L150H loader. Four 14tonne EC140E crawler excavators have gone to work for the group’s construction division, and the business has also ordered three other new excavators, including an EW210D wheeled materials handling excavator; a 22tonne crawler excavator, and an ECR88D reduced swing excavator.

Introducing other new models, Volvo CE says its largest crawler excavator, the new 90tonne weight class EC950E, which is available in less regulated markets, has a bucket break-out force of 424kN and an arm tear-out force of 408kN.

Powered by a 446kW Volvo D16 engine, the machine utilises advanced technology, and an attachment management system enables the use of various attachments.

The company’s EC750E crawler excavator, a 75tonne class machine, is powered by Volvo’s Tier 4 Final/Stage IV compliant D16 engine, delivering 374kW, and utilising advanced fuel efficiency technology.

“The EC750E offers innovative electro-hydraulic technology, optimised to operate in harmony with the robust engine, delivering greater operator control and productivity. The hydraulic system, in combination with Volvo’s advanced ECO mode, works in unison to reduce internal losses in the hydraulic circuit, resulting in improved fuel efficiency without any loss of performance in most operating conditions,” says the company.

Volvo CE’s new L45H and L50H wheeled loaders are equipped with Volvo’s Torque Parallel (TP) linkage, while a long wheelbase, low centre of gravity and good weight distribution are said to give the machines superior stability on rough and uneven terrain.

Both machines feature Volvo’s intelligent load-sensing hydraulic system that drives power to the hydraulic functions according to demand for a fast response, shorter cycle times and reduced fuel consumption.

The company says that an optional Boom Suspension System (BSS) boosts productivity by up to 20% by absorbing shock and reducing bouncing and bucket spillage.

Doosan Bobcat EMEA’s new DL220-5 wheeled loader, the latest addition to the company’s DL-5 generation of Stage IV-compliant machines, offers features such as a new high comfort cab; a powershift transmission with optimised hydraulic pumps; multiple power modes, Z-bar lift arm, and return to dig and limited slip differentials on both the front and rear axles.  

The DL220-5 is powered by a six-cylinder, turbocharged Doosan DL06P water-cooled diesel engine which meets Stage IV emissions regulations without the need for a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) aftertreatment technologies.

Doosan says that with limited-slip differentials as a standard feature, the DL220-5 wheeled loader has more traction when digging, grading or loading trucks.

The DL220-5 is factory-installed with the new CoreTMS state-of-art wireless fleet monitoring system, a feature not previously available as standard on Doosan wheeled loaders and now incorporated in all new DL-5 generation machines.

Meanwhile, the first three Liebeherr L 566 XPower wheeled loaders to be delivered are being used by RBS Kiesgewinnung in Germany for loading of sand and gravel at a plant in Hamburg that operates under wet conditions. A suction dredge extracts the mixture from the lake and wheeled loaders transport it to heaps for interim storage, a job that will now be done by the new L 566 XPower. Each loader will handle up to 3,000tonnes of material/day.

“Even under the tough conditions in our sand and gravel plant, our new XPower wheeled loaders use up to 30% less fuel per operating hour at full capacity than the previous model,” says Andreas Buhk, company owner and managing director.

Not far from Balve, North Rhein-Westfalia, Germany, Cemlapis Warstein, a subsidiary of HeidelbergCement, is using a Liebherr R 960 SME (Super Mass Excavation) crawler excavator to load limestone into 50tonne dump trucks that supply the primary crusher with material to be processed in the downstream steps to form crushed sand, mineral aggregates, split and other special products.
