A Tier 4 Final-compliant tracked loader has been unveiled by JCB at bauma 2013. The 225T machine is powered by JCB’s Ecomax engine that uses up to 9% less fuel than the previous Dieselmax version, which was, itself, said to be up to 16% more efficient than some competitor machines. In addition to the new engine, the large platform models in JCB’s 17-strong skid steer/compact loader range also get electro-hydraulic controls as used on small platform machines. This allows companies to specify H-pattern contro

Caterpillar’s industrial engines division is using the C7.1 as a common engine platform as a replacement for the C6.6 as it meets Tier 4 Final/Stage IV emissions regulations. It means the 7.1litre six-cylinder C7.1 offers power ratings from 116kW to 225kW in either single turbo or series turbo configurations, and adds an SCR catalyst and diesel exhaust fluid dosing system as part of the existing exhaust after-treatment process.

Hatz’s Diesel’s 1D81 Hydro concept has been developed to offer a low noise level solution for applications using single-cylinder diesel engines. Still at prototype stage, the 667cc and 772cc capacity single-cylinder engine is a new variant of an existing Hatz engine design. As such, it uses common components from the Hatz range, but it differs with an all-new cylinder block and cylinder head design that includes a water jacket, allowing liquid cooling to be introduced.

Ammann Group, a leading manufacturer of asphalt mixing plants, compacting machines and asphalt pavers, and India-based construction equipment supplier Apollo Construction Equipment, have announced a joint venture for the Indian market. The announcement was made at a bauma press conference jointly hosted by Ammann CEO Hans-Christian Schneider and Anil Patel, chairman of Apollo Construction Equipment and vice chairman of the joint venture Ammann Apollo India Private Ltd. With three manufacturing facilities, a

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.

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.

Volvo Trucks has updated its FMX construction tipper range, first launched in 2010. The latest FMX adopts the Euro 6 engine line-up introduced earlier this year in the firm’s on-highway FM and FH trucks, with D11 offerings at 246-335kW and D13 engines delivering 313-402kW. These engines are equipped with non-cooled exhaust gas recirculation (EGR) and a diesel particulate filter (DPF). The FMX range is available with Volvo Dynamic Steering (VDS), which uses an electric motor to assist the hydraulic power ste

Among a record 29 world releases, Wirtgen has unveiled its new specialist concrete paving machines at bauma 2013. The SP 81 / SP 81i, the SP 82 / SP 82i and the SP 84 / SP 84i are highly flexible machines for paving concrete profiles of varying sizes. The SP 81 / SP 81i can produce sewerage drains, concrete barriers, kerbstones or narrow paths up to 2.2m high and 3.0m wide as standard.

Doosan Construction Equipment has shown a prototype of its 6tonne DX62R-3, a replacement for the DX60R. Due to be launched in the second half of the year, the machine delivers a 33% increase in hydraulic flow from a new load sensing system. Digging forces are said to be greatly improved, with bucket force now up to 4,400kg, and increase of 7%, while dipper arm force is up to 2.9tonnes. This improved performance has been combined with a longer arm for a larger working range. The machine uses the same cab tha

Perkins has completed its line-up of four-cylinder engines for Tier 4 Final/Stage IV with the introduction of the 854F-E34TA – the latest in its 800 Series range. The compact, four-cylinder, 3.4litre engine incorporates specially developed SCR technology for the first time. Packaged separately from the DOC module, it can be mounted in either a horizontal or vertical position, giving OEMs of compact machinery greater installation flexibility in the engine bay.
