Mecalac has introduced a rail-road version of its compact 8MCR crawler excavator. The machine has two sets of hydraulically-lowered rail wheels that use the dozer blade circuit to lift it clear of the tracks. The wheels can be set at 1,000mm, 1,435mm and 1,668mm widths, to suit various European rail networks. Activation of the on-rail function automatically turns on all regulatory lighting, limits the working height of the equipment, limits upper structure rotation and activates a load monitoring system.

Atlas Weyhausen wheel loaders have been given a power boost as part of the developments to meet the latest emission standards. The company is showing two of the new machine types, labelled as ‘e’ models, at the stand of its French business partner Payen. The new ‘e’-type wheel loaders have been designed to provide a significant gain in terms of power and performance. Engine outputs now amount to 70kW for the AR 80e and 85kW for the AR 95e at 2,200rpm, representing a power increase of more than 15% for each.

Liebherr took the wraps off two new tracked excavators at INTERMAT, catching many seasoned industry observers by surprise. The 24tonne R924 replaces the R916, while the heavier (50tonne) R956 succeeds the R954. The upgrade includes Stage IIIB engines featuring diesel particulate filters. The bigger machine can be specified with an extendable (LC-V) undercarriage, which has a 3metre travel width, meaning it can be transported on the roads of some countries without being disassembled.

Doosan’s new Stage IIIB-compliant DX300LC-3 and DX340LC-3 crawler excavators are said to offer 6% to 17% higher productivity, along with fuel saving and reduced costs. The 30 and 35tonne machines have a new ROPS and OPG-certified pressurised cab. A heated air suspension seat and a new cab suspension cut vibration by 20% and reduce the sound level in the cab to 71d(B)A.

A 6% increase in lift capacity, greater digging efficiency, reduced emissions and up to 5% lower fuel consumption are the benefits of Case’s new CX470C excavator. The 47 to 50tonne machine has a 9.8litre Stage IIIB engine delivering 270kW at 2,000rpm which contributes to a 5% increase in fuel efficiency and 5% faster cycle times. Some of the savings come from a Boom Economy Control, which automatically reduces engine revs and hydraulic power to the boom when speed and power are not a priority.

Chinese manufacturer Sany Heavy Industry has introduced a five-model crawler excavator range to the European market. The C Series excavators range in operating weight from the 7.5tonne SY75C to the 35.5tonne SY335C, with models at 13.5tonnes, 21.5tonnes and 23.5tonnes. The machines are powered by Stage IIIB Isuzu and Mitsubishi engines. Sany sold more than 20,000 of these machines in the Chinese domestic market in 2011 and is keen to expand its share of the European excavator arena, through its European

Dominating Hidromek’s stand at INTERMAT is its 30.5tonne HMK300LC excavator. In common with the other gen series excavators, the HMK300LC has Hidromek’s latest cab design, which offers more room for the operator and the “Opera” user interface designed to optimise the excavator’s force, speed and consumption.

Caterpillar has given its D6N fine grading and muck-shifting dozer an EU Stage IIIb emissions-compliant engine for 2012. The 129kW C6.6 Acert engine now gets a DOC and DPF with passive regeneration, helping the machine to a 2% productivity boost primarily from sharper throttle response. There is also a selectable economy mode – linked to 2nd gear – that automatically shifts the dozer into 3rd gear when reversing, and simultaneously reduces engine revs from 2000 to 1700rpm. This system can give fuel saving

Komatsu said commercial availability of hybrid technology for the European construction equipment market is now available, in the guise of the Hybrid HB215LC-1 excavator. As a second-generation hybrid excavator, the HB215LC-1 replaces the PC200-8 Hybrid with an operating weight of 21tonnes and bucket sizes ranging from 0.8-1.05m3.
