John Deere Power Systems used bauma to complete its engine line-up for Tier 4 Final/Stage IV emissions regulations. This included the arrival of the PowerTechTM PWL 4.5L engine, which meets emissions regulations without a diesel particulate filter (DPF). Spanning outputs from 63-104kW, this four-cylinder, 4.5litre engine offers reduced cost and improves engine packaging by eliminating the DPF, said Deere. However, the engine uses selective catalytic reduction (SCR), a diesel oxidation catalyst (DOC) and coo

Volvo Penta is introducing start/stop technology that could cut fuel bills by 5% by turning off engines when they are left idling. Such systems have become increasingly common of late in private cars, where they stop the engine while waiting in a queue or at a red traffic light.

TRACTO-TECHNIK intends to maintain its position as a leader in the field for trenchless tunnelling technology with the launch of some innovative new designs with its Black Mole and latest Grundomat N design, as well as other key introductions. Its 7th Grundomat N generation features an innovative crowned head form that is said to guarantee a high penetration force and target precision in stony soils. The GRUNDOMAT N is optionally available with the proven stepped head from the previous generation. A further

From Bell Equipment comes a special version of its B30 truck in the shape of a 4x4 version of the B30D. Introduced as part of the firm’s VersaTruck programme, the 4x4 version of the B30D has been developed for a range of applications such as use in underground tunnel construction and underground mining, or quarrying. The shorter rear chassis and single rear axle means that the truck is able to manoeuvre in tighter spaces than the conventional B30 machine, suiting it to applications such as underground opera

A special version of Hidromek’s HMK220LC excavator is now available for use in underground applications. This machine features additional reinforcement and protection to ensure its longevity in the tough underground application, as well as providing extra safety measures for the operator. The same Tier 4 Interim/Stage IIIB emission certified engine and hydraulics components are used as in the standard machines, although additional after-treatment systems are available to meet underground working requirement

Herrenknecht’s innovative Pipe Express system offers a novel semi-trenchless method of installing pipelines effectively and efficiently. The system can cope with pipe diameters from 800mm-1.5m and is a combination of tunnel boring machine (TBM) technology with a chain trencher. The TBM unit, trencher and buggy run on the surface, along with an operating vehicle and the equipment is modular and said to be easy to transport and set-up on site. Silke Rockenstein is in charge of corporate communications at the

Atlas Copco says its new Boomer E-series underground mining and tunnelling rigs, available via Atlas Copco’s own worldwide sales organisation from 2013, offers the next generation of rig control system with an improved user interface, including a new intuitive touch-screen, and user-friendly design. “With these improvements, we are confident that the new Boomer series offers one of the most powerful and productive underground mining rigs and tunnelling rigs on the market,” says, Johan Jonsson, product manag

Sandvik Construction is launching its new Alpha 330 drilling tool system for drilling and tunnelling. It has been developed with special features that control power and ensure this power is transmitted into the rock as efficiently, accurately and economically as possible. The company says that in tests, in varying rock conditions, the new design has been proven to deliver a 30-80% increase in rod life; provide more accurate collaring and straighter blast-holes, thereby delivering greater advancement and imp

Herrenknecht has developed a boxhole boring machine (BBM), based on its proven microtunnelling pipe jacking technology. The BBM1100 has been designed to drill slot holes and inclined shafts with a diameter of up to 1.1m and a maximum length of 30m. The machine uses a compact crawler base, with a modular jacking frame, cable drum and power pack that can be positioned separately if required.

Sandvik Construction has added the DC125R to its DC family of compact top hammer drill rigs. The remote-controlled self-propelled rig has a four-wheeled carrier that can also be equipped with rubber tracks for added mobility in difficult terrain. Capable of drilling 22-45mm diameter holes, the machine is capable of up to 300-400m3 in an eight-hour shift. The 3,150kg mini rig is powered by a 37kW engine that drives a 5.5kW rock drill. Designed primarily for foundation drilling, road cutting, trenching, line
