Polish manufacturer Dressta, now owned by LiuGong, has updated the engine in its TD14R dozer to bring the machine into line with recent emissions regulations. The TD14R is powered by a Cummins QSB6.7 engine delivering 119kW. The 18.7tonne dozer is available in standard, long and low ground pressure track models, with a three-point suspension system to maintain tractive effort on rough ground.

The latest wheeled loader from Terex – the TL120 – not only features a 16% more powerful 74.4kW Stage IIIB-compliant Deutz engine, but uses the Terex Smart Control operating system to increase fuel efficiency. The 7.1tonne machine uses a menu system similar to that found on a smartphone to configure the machine for specific applications.

Komatsu’s new PC138US-10 short-tailswing hydraulic excavator has an operating weight between 13,400 and 14,467kg, comes with a 69.7kW Stage 3B/Tier 4I-compliant engine and has improved hydraulic efficiency and operator comfort. The PC138US-10 is supported by the Komatsu CARE complimentary three-year/2,000hr maintenance programme. The company said lift capacity and stability of the compact machine are comparable to a conventional excavator, while the contoured cab swings within the same radius as the count

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
