Greater fuel efficiency, improved digging performance and revised styling are among the changes to be found on Volvo’s latest D-series wheeled excavators. The four-model EW range spans 14-21tonnes and benefits from a new engine, cab, hydraulics, substructure, boom, arm and controls. There is more power with D-series, from stage IIIB engines that use V-ACT technology. The four cylinder (EW140D) and six cylinder engines produce high torque at low engine speeds, said Volvo, giving rise to low fuel consumption.

Stanley claims its GTR20 B01 power unit is at the cutting edge of construction site hydraulic power for tools. The generator, on sale in America but new to the European market, delivers a hydraulic flow of 40 or 2* 20L/min at pressures up to 2,000psi, with heat rejection capacity exceeding the EHTMAS recommendation of 5hp.

Simex has introduced a visual indication on its planning attachments – the Performer – which enables operators to utilise all a carrier machine’s available power while avoiding stalling. The patented system automatically resets to reflect each machine’s maximum power and, according to the company, the device typically improves production rates by 25 to 30%.

The new XP2000 breaker from Promove is designed for 22 to 29tonnes carriers and its 145mm diameter tool delivers 5900 joules of energy at between 350-650 blows per minute. A flow rate of 160litres/min at 180bar is required and the breaker can work with a backpressure of up to 25bar.

Launched at INTERMAT in prototype form, the SV100-1 is now Yanmar’s largest excavator. Tipping the scales at 10.3tonnes, the reduced tailswing midi excavator gets a two-piece boom and additional counterweight. Powered by a 54.7kW 4TNV98T engine, the excavator offers a 4.48m dig depth, sits on 450mm wide rubber tracks, and measures 2.3m wide. A fourth auxiliary circuit is available as an option.

The ‘world’s smallest crusher bucket’, the MB-L160, made its debut at INTERMAT on the MB stand. Weighing just 1,350kg, the 0.3m3 capacity bucket has a throughput capacity of up to 22.5tonnes/hr and fits to machines between seven and 12tonnes, including backhoe loaders. Product size adjustment ranges from 15mm to 50mm.

Xcentric Ripper has launched the XR 80 Ripper, the largest excavator attachment in a range of eight models. The XR 80, which has a total weight of almost 10,000kg, has been introduced following successful testing carried out last month in Spain and France. It is designed to be mounted on excavators from 80tonnes to 120tonnes and used in larger quarries and on major construction sites.

Terex has introduced the production version of its Twin Drive TC16 mini excavator. Equipped with both a 13kW diesel engine and an 11kW electric motor, the 1.9tonne machine can be used in confined spaces with zero exhaust emissions. A 15m cable reel is installed behind the cab, allowing the machine to travel under electric power.

Terex launched three compact excavators at INTERMAT – a micro TC10 and the reduced radius TC15 and TC19. All three have been developed in co-operation with an Italian manufacturer. The TC10, which weighs just 1 tonne, has a travel width of 760mm, allowing it to pass through a standard doorway. Hydraulically extending track frames offer a digging width of 990mm for maximum stability.

Selwood Pumps has had promising meetings at INTERMAT with potential new distributors who have visited its stand in the UK Pavilion. Exports through distributors account for 75% of the pumps that Selwood manufactures. The company is highlighting the S100, S150 and S200 Super Silent pumps, which have recently been improved by the introduction of a close-coupled configuration as part of an ongoing development programme across the entire range.
