Hamm is widening its line-up of new generation soil compactors
Hamm continues to develop its sophisticated soil compactor range with the addition of models aimed at the 11-16tonne weight classes. These are powered by Tier 4 Interim/Stage IIIB compliant diesels and share the same design concept as well as features and many components with the existing 18-15tonne rollers. The high compaction performance and unobstructed sight lines from the cab of the larger machines have also been carried over into the smaller units. The H11i, H13i and H16i compactors have 2.14m wide d

Improved performance is claimed for Hamm's sophisticated new soil compactors
228 Hamm continues to develop its sophisticated soil compactor range with the addition of models aimed at the 11-16tonne weight classes. These are powered by Tier 4 Interim/Stage IIIB compliant diesels and share the same design concept as well as features and many components with the existing 18-15tonne rollers. The high compaction performance and unobstructed sight lines from the cab of the larger machines have also been carried over into the smaller units. The H11i, H13i and H16i compactors have 2.14m wide drums, compete in the 11tonne, 13tonne, and 16tonne classes respectively and are all powered by four cylinder Deutz diesels rated at 105kW, with sufficient cooling allowing operation in ambient temperatures as high as 50°C. The sophisticated combustion technology includes an after-treatment system with DPF filter to reduce particulate matter. High manoeuvrability is claimed as well as good stability on uneven or sloping terrain, while the machines are available with smooth drum, with padfoot segments or with padfoot drum. The 13tonne machine is also available with a VIO drum, capable of compacting with either vibration or oscillation. Standard equipment includes the Hammtronic machine management system, which optimises traction and vibration drive while reducing fuel consumption while a new feature is the optional telematics interface. This can transfer data for fleet management purposes and can also be used for remote diagnostics or as an anti-theft protection. Customers can also opt for the HCQ Navigator, which is available as a factory-fitted option. This system enables precise, even compaction as well as comprehensive compaction control. A new HCQ function also enables simple data export in conformity with American analysis software.
As with the large compactors of the H series, all service points and batteries are also located on one side with the smaller models. The innovative air filter is said to be simple to clean and replace. The new series also comes as standard with a secure storage space under the engine cover in which to keep a toolbox for example. Hamm also offers the compactors with optional low-energy, long-lasting LED working lights on the cab as well as a main headlight with low beam and additional full beam. Reversing cameras are also available as an additional safety feature, while a display allows the driver to check for obstructions behind the roller. These cameras are available now as an optional extra for all H series compactors and can also be retrofitted to all existing machines.
Haver & Boecker is expanding its screen range with the addition of the Ty-Wire hybrid screen deck and of ultrasound screen decks. Ty-Wire hybrid screens use wire that is covered in polyurethane, providing a greater open area than a standard PU screen but with a lifetime that can be 4-6 times longer.
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
The Arja Group is broadening its range of crushing and screening equipment with its latest generation of impact crushers. The new series TAURO 10 PE models join the range, along with the durable MA 0806 jaw crushers and HN 36-3 screens. The new impact crushers are designed to work with highly abrasive materials and can also be used for soft materials. The firm claims that these impact crushers offer benefits over cone crushers in terms of material shape and reduced fines. The new TAURO 10 PE features advanc
Hatz Diesel will take the wraps off a new engine family at Bauma, with the launch of the H series, a 2.0–litre water-cooled engine family that features Bosch common rail fuel injection with pressures up to 1,800 bar. Producing 56kW (75hp) and 130Nm of torque, the engine meets European Stage IIIB emissions regulations and US Tier 4 Final standards. The engine, a first at this size for the company with liquid-cooling, uses exhaust gas recirculation (EGR) and a diesel oxidation catalyst (DOC) but does without
