This sophisticated tool incorporates a touchscreen and radio remote controls and supports work site digitalisation. All relevant process information and reporting can be displayed on the user’s smartphone without having to leave the feeding device. SPECTIVE CONNECT also offers new features, which will make work for the operator easier according to the firm. One of the key features is a new configuration tool  that helps the operator select the correct machine settings for each application.

The 10-tonne weight class is new to the Doosan range and the DX100W-7 offers a high performance for urban and road maintenance applications. The integral 1.35-tonne counterweight ensures the highest stability for lifting work in combination with the articulated boom and long arm. The boom ensures that the operator can position the machine as close as possible to trucks during loading.

In addition, the DX100W-7 offers maximised lifting capacities and digging forces, as well as satisfying a requirement in some countries for a wheeled excavator with a travelling height of under 4m.

Other safety features include a ROPS cab with a premium seat as standard. An operator can use the large touch screen to easily browse all machine settings, including the view from the standard side and rear view cameras. The availability on the DX100W-7 of an optional 360° all-around view camera, linked with an optional ultrasonic detection system is another exclusive for a machine of this size, says Doosan.

With 75kW of power at 2000 RPM provided by a Doosan D34 G2 Stage V engine, the DX100W-7 has the highest engine power, hydraulic flow and traction force in this class. The high flow from the smooth and precise hydraulic system can drive all kinds of attachments. In addition, there are two different pumps providing independent hydraulic flow for the transmission and to fully power hydraulic tools on the front end.

The new DX100W-7 comes with DoosanCONNECT TMS 3.0 wireless fleet monitoring system.

Both machines are powered by 6.7litre Cummins diesels rated at 168kW for the TC7A and 186kW for the TC11A and have hydrostatic drives, featuring proven hydraulic components from Rexroth. The firm says that the operators benefit from larger and more comfortable ROPS/FOPS cabs with better all round visibility than competing machines.

The machines are said to good offer good traction even in the worst conditions and can cope with 50% slopes. The suspension systems feature walking beams and six rollers, a configuration said to ensure a combination of high traction and smooth running. The smaller machine has a dump area of 3.5m3 while the larger unit has a dump area of 5.25m3. Fold down sides for the rear area also allow the machines to be used for carrying equipment for projects on remote sites. The machines can also be equipped with access equipment, loader cranes or compact concrete mixer units for example.

Slotting into the range between the existing R 926 and R 930, the R 928 weighs under 30tonnes and this makes it easier to transport. Meanwhile, the sophisticated, semi-automatic machine control package is said to ensure precise and productive operation, without the need for reworking. Factory-installed 2D and 3D machine controls will be available in future for Liebherr’s Generation 6 and 8 Liebherr crawler and wheeled excavators as optional equipment.

Improvements have been made in arm and boom structure, undercarriage and attachment groups by using more durable materials for the H4 Series. The 500 LCHD has a more durable structure and offers high performance and long-life that are essential for long hours on duty in marble quarries, mines and large construction sites.

The 52,000kg 500 LCHD  with its Pentagon-type chassis is powered by a stage V-EU certified ISUZU-6UZ1X engine producing 270kW at 2000 rpm. Travel is fully hydrsostatic.

The hydraulic system incorporates double variable displacement axial piston pumps with a maximum flow rate of 2 x 376  litres per min.

Cat Grade with Slope Assist automatically maintains pre-established blade position without a GPS signal, so no additional hardware or software is needed. Factory integrated Cat Grade with 3D uses GPS to control the blade so you can get to design plan faster and it has no blade masts. The antennas and receivers are housed in a low-profile roof-mounted spoiler.

In the cab, the operator interface is intuitive and easier to use, thanks to a 254mm touchscreen Android OS platform that operates like a smart phone. Slope Indicate shows machine cross-slope and fore and aft orientation right on the main display to help operators with slope work.

For added safety, there is a standard high definition rear view camera that shows prominently in the main display.

The machines are the well-accepted Doosan models built in Norway and now being offered in Hyundai branding following the tie up between the firms.

The firm claims equal weight distribution due to the sloping rear chassis frame design, which is said to deliver stability by distributing more load towards the centre of the machine and resulting in a low centre of gravity. The machines also have the proven tandem rear axle bogie configuration, which is said to offer a higher degree of articulation than competing designs and optimises ground contact to maximise traction. The machines also feature the articulation joint turning ring mounted close to the front axle, which further helps to equalise load distribution between the front to rear and across the front axle during steering.

The trucks are powered by Stage V-compliant Scania diesels. The HA30A uses a five-cylinder, 9.3litre, DC9 turbocharged diesel, developing 276kW and 1,876Nm of torque. The larger HA45A employs a six-cylinder, 12.7litre DC13 diesel engine, producing 368kW) and 2,476Nm of torque.

Both engines drive through eight-speed ZF automatic transmissions, with integrated retarders. The torque converter has lock-up in all gears, reducing fuel consumption and increasing efficiency. Fuel, AdBlue diesel engine exhaust fluid and a standard auto-lube greasing system can all be easily accessed from ground level. The engine canopy tilts forward for access to filters and fill points, while the cab structure can be tilted to provide access for repair and maintenance.

Hyundai’s Himate telematic monitoring system is fitted standard, with satellite and GSM connectivity. This allows customers to monitor productivity, fuel consumption, system warning and maintenance status remotely, reducing downtime and improving fleet utilisation.

The Stage V compliant DX1000LC-7 also has the highest hydraulic flow for this size of machine, providing best-in-class performance, with higher productivity, lower fuel consumption and smoother controls. For the operator, there is a spacious cab where noise is reduced through enhanced sealing of the engine compartment and extensive use of sound-dampening materials.

The DX1000LC-7 excavator is powered by the new stage V version of the well-proven Perkins 2806J diesel engine, providing a high power output of 469kW, more than any other machine in this class. The engine meets Stage V emission regulations thanks to exhaust gas recirculation, selective catalyst reduction, diesel oxidation catalyst and diesel particulate filter (DPF) after-treatment technologies.

The DPF automatically regenerates every 25 hours and the excavator continues to work unaffected during this regeneration phase. The operator can check the status of the DPF via the display on the gauge panel in the cab.

The high output of the engine is combined with a Virtual Bleed Off (VBO) hydraulic system (D-ECOPOWER+) and controlled by electric manipulator (FEH). This provides a best-in-class hydraulic flow of 1569 l/min and a high system pressure of 360 bar, together contributing to the best performance in the 100-tonne market.

Doosan’s D-ECOPOWER+ FEH technology uses an electronic pressure-controlled pump within a closed centre hydraulic system to optimise productivity and fuel consumption, depending on the mode selected. A closed centered main control valve minimises pressure loss, while the electric pressure-controlled pump manages and optimises engine power more effectively.

The DX1000LC-7 is factory-installed with DoosanCONNECT wireless fleet monitoring system.

Komatsu's new PC4000-11e features easy access and maintenance. A new 45° access system means entry is safer for the operator. The machine is equipped with three emergency exits on two sides and one emergency exit hatch from the machinery house to the roof. Located on the cab side as well as the opposite side on the machinery house, a stable ladder is mounted in two pieces as a flip down, this also has an anti-slip surface to ensure safe egress.
 
Meanwhile, KOMTRAX Plus monitors all data for quick and efficient handling directly in the operator’s cabin. As well as this, a new simplified electrical system is now standard. Komatsu controllers reduce nodes and provides redundancy in the electric system for more efficiency in the mine.

Special features include KomVision and payload management. KomVision offers a 360° bird’s eye view for safer machine operation. A monitor in the operator’s cabin shows the full view of the machine and its surroundings. The operator is additionally able to select one of the cameras for a detailed view of a required area by way of a 10-inch touch panel.

Argus PLM identifies the bucket payload. With the operator able to see the bucket fill, the number of required passes per truck can be reduced which means a more efficient and quicker truck loading. In the future the system will be standard, it is currently available as an option as Argus ready, as an integrated system.

The same six cylinder Mercedes diesel rated at 260kW that meets Stage V/Tier 4 Final emissions requirements is fitted to the special narrow variant as to the standard machine and this also drives through the same six speed Allison transmission. The payload also remains at the same at 28tonnes, though the dumpbody is revised to keep it within the 3m width limits. The machine offers a top speed of 50km/h and is equipped with an automatic retarded, while the dumpbody retains its heating kit to ensure efficient tipping with sticky materials.

The machine has been developed to meet the needs of those earthmoving contractors or quarry firms that sometimes have to move machines on road.
