Engines, Components & Tyres

For the last two years a team of European partners has been examining the interaction between vehicle tyres and road surfaces. According to the UK's TRL, one of the partners in the European project Tyrosafe (Tyre and Road Surface Optimisation for Skid resistance And Further Effects), devices to measure skid resistance were developed at the forerunner of the UK's TRL in the 1930s.

Berco says field test prove that its new ROBUSTUS (ROtating BUShing Track Undercarriage System) increases track life by 35% with a maximum of 6,000 hours of operation and reduces operating costs by 15-25%.

Upgrades to Dynapac's Racoon+ poker drive include rubber protection against shocks and prevent the drive unit's body from being in direct contact with dust, helping to protect the electric motor. This flex shaft concrete vibrator is a complete high frequency vibration system eminently suited for daily operation on small and medium sites for applications such as walls, floors and pre-cast fabrication.

WORK ON a major upgrade at a busy German road junction is expected to be completed by the end of 2011. To assist in the project, two Putzmeister large-boom concrete pumps, an M 58-5 from Berger Beton and an M 62-6 from BFM Betonförderdienst in Munich, arrived at the Neufahrn motorway junction, north of the city. The junction, when viewed from above, looks like a flatly pressed four-leaf clover, and can no longer cope with traffic volumes. Two national motorways, the A 9 and the A 92, intersect at the

Engine manufacturers have had to jump through regulatory hoops in recent years, meeting requirements for diesels with ever cleaner exhaust emissions. When this programme was first proposed, many believed the final aims could not be achieved. However on January 1st 2011, the Tier 4 Interim/Stage IIIB emissions regulations will come into force in North America and Europe and all the major diesel manufacturers will have suitable products at the ready. The Tier 4 Interim/Stage IIIB emissions regulations require

Perkins is powering up with a new line of Tier 4 Interim/Stage IIIB compliant range of industrial engines. These diesels are said to offer an increase in power and torque as well as the number of options available. These power packages comprise engine, aftertreatment, radiator, air cleaner and optional compressor, which can all be mounted on a base frame. The first commercially available package will be the 1206E, a 7litre, six cylinder engine capable of producing up to 205kW.

Hitachi Construction Machinery (Europe)/(HCME) has said that it is increasing its focus on the supply of spare parts with the opening of a new European parts centre in April 2011. This represents a significant investment of €e12million in the 53,000m2 facility (22,000m2 covered), formerly owned by the car manufacturer Citroën and located in the city of Oosterhout in the south of The Netherlands. HCME's existing 7,600m2 European parts centre is also situated in Oosterhout, but the move to the new complex wil

Deutz's TCD3.6L4 diesel engine claims high output, low fuel consumption and low noise and exhaust emissions. According to Deutz, the four-cylinder engine sets a new benchmark in its class in terms of torque curve and compact dimensions and also features smooth running characteristics. The engine has sophisticated injection technology and exhaust after-treatment and delivers a torque curve that peaks at 460Nm at a speed of 2,300-2,600rpm over its entire power output range of 50-95kW.
