Atlas Weyhausen has unveiled its biggest and most powerful wheeled loader yet – the AR 105e – which boasts a service weight of 9,450kg and a standard bucket capacity between 1.6 and 1.8m³. The AR 105e’s engine is a water-cooled Deutz Diesel motor TCD 4.1 with four in-line cylinders, an output of 105 kW@2,200rpm and a maximum torque of 550Nm. The motor is turbocharged, with charge cooling and external cooling of recycled exhaust gases. The modular system of exhaust after-treatment meets the demands of EU sta

Hyundai Heavy Industries is showcasing a hydraulic hybrid machine at bauma. The R220-LC Hi-POSS is a 22tonne-crawler excavator with a system that allows brake energy to be used for other functions. Hi-POSS stands for Hyundai intelligent power optimal sharing and energy saving. “This is the most novel thing we have,” said Hyundai product engineer Joachim Van de Perre. “With a conventional excavator, when you brake, the energy heats the hydraulic oil. Here we use the energy to perform another task with the ma

Hyundai Heavy Industries is showcasing its new Robex 9A series of excavators – six crawler excavators and three wheeled excavators – all of which have engines that meet the Tier 4 Interim/EU-Stage IIIB standards on engine emissions. Hyundai has elected to use exhaust gas recirculation (EGR) technology – rather than liquid urea – to meet the emissions targets. “We have full automatic DPF regeneration, which is a big advantage,” said Hyundai product engineer Joachim Van de Perre. “It means that all the items

New Holland is exhibiting the 17.9tonne operating weight D150CXLT dozer. It is one of a range of three dozers between 13 and 20tonnes using Tier4i engines fitted with SCR technology to achieve the emissions target and produce a 10.5% fuel saving. It is said to have the quietest cab in the industry (76dB(A)), best-in-class drawbar pull with hydrostatic transmission (311kN) and integration with GPS and laser guidance.

GOMACO is introducing the GT-3200 sidewalk paver with an adjustable aggregate base mold on the front and a sidewalk paving mold on the rear. This three-track paver is designed for zero-clearance sidewalk rehabilitation projects, to meet a contractor’s unique request. The front-mounted adjustable aggregate base mold spreads the base aggregate for the sidewalk. During the first pass, rock is placed on grade and an auger spreads the material, while three pan vibrators fitted to the mold start compaction. The b

The G+ Connect is GOMACO’s latest proprietary CAN-based network products allowing fast, two-way communication between all accessories and the G+ controller. This closed-loop control system for the electronics and hydraulics links the paver’s valves and various sensors and delivers high accuracy. The system is said to allow tighter, faster, and more accurate machine corrections and improves communications between components for precision setup and paving. The G+ Connect uses the G+ control system and GOMACO’

Described as a “game-changer” by Gary Stampanato, vice president of Caterpillar’s excavation division, the Cat 336E H hybrid excavator will be officially launched at the bauma show. Using new hydraulic technology developed by Cat, the hybrid machine is said to deliver uncompromised performance, durability and reliability. Cat claims the 336E H delivers industry-leading productivity, with up to 50% greater fuel efficiency over the 336D. It is also said to use up 25% less fuel than a standard 336E, and up to

Hidromek has added long-reach options for three of its excavators – the HMK220LC, HMK300LC and the HMK370LC. Aimed at special earthmoving and drainage applications, the excavators carry LR branding and have ground level reach of 15.06, 18.19 and 16.6m respectively. Load over heights range from 10.85m with the HMK220LC LR to 12.59 with the HMK300LC LR. The long-reach HMK220LC delivers 7,300kgf of bucket digging force with a 0.45m3 bucket, with the figures rising to 1m3 and 11,400kgf with the HMK370LC LR.

Doosan Construction Equipment has launched a Dash-3 version of its popular reduced-radius 15tonne excavator, the DX140LCR-3. Powered by a Cummins QSB4.5 Stage IIIB-compliant engine, with exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), the machine has 10% more power and 15% more torque than the previous model. Both main boom and dipper arm forces get an 8% boost, while travel speeds are increased to 5.3km/h, resulting in a claimed a 10% increase in productivity.

Hitachi Construction Machinery has introduced a hydraulic technology known as TRIAS on its Dash-5 Zaxis excavators from the ZX210LC-5 to the ZX350LC-5. Developed to reduce fuel consumption, the system uses three hydraulic pumps and a control valve, which efficiently divides the flow from the pumps into each actuator as required.
