2203 CIFA is introducing an innovative hybrid truck mixer in the shape of its new Energya 9 model. This features a conventional 9m3 capacity mixer drum however the rotational drive system is electric and the machine is also equipped with a lithium ion type battery pack that is charged up while the truck is being driven, assisted by regenerative braking. When the mixer stops on-site, the drive to the drum is supplied either by the battery pack or can be plugged in to a mains power supply. This allows the truck driver to turn off the engine and save on fuel, as well as reducing exhaust emissions. Mixing and unloading can be carried out using the battery pack or mains power, offering a significant reduction in overall fuel use over time. For a fleet of mixer trucks, the fuel saving is likely to be substantial and provide a comparatively rapid payback time for the hybrid technology. There may be long term benefits for the truck’s engine too as this will avoid the need to have the diesel running at idle for long periods on-site, reducing the risk of cylinder wall glazing that can occur when the engine load is very light. As with more conventional truck mixers, customers can choose from a range of suitably-sized carrier vehicles to suit local market requirements and customer preference. This system has been developed in partnership with Milan Polytechnic and CIFA has filed a number of patent applications for the technology. The package is one of several innovative systems CIFA has introduced following its purchase in 2008 by Chinese firm 1175 Zoomlion, with its parent proving extremely keen to invest in research and development and new technology.
JCB has introduced two new soil compactors; the VM117D and the VM137D with operating weights of 11tonnes and 12.2tonnes respectively. The single-drum vibratory compactors can be used for a wide range of work in infrastructure and housing projects and have a smooth drum as standard with pad foot drums as an option. They are powered by JCB’s 93kW Stage IIIB/Tier 4 Interim Ecomax engines, which meet the emissions target without using a DPF and are said to deliver fuel savings of 16%. Changes to the compaction
Sennebogen has plugged the gap in its telescopic crawler crane range with the introduction of the 673R-HD. The 70tonne capacity machine sits between the firm’s 40 and 80tonne models, offering a 36m four-stage main boom with two fly booms of 8m and 15m. This gives a maximum reach of 51m. The 673R-HD is powered by a Stage IIIB/Tier 4 Interim standard Deutz engine delivering 160kW. Telescopic track frames allow for a maximum transport width of just 3m, with fast set-up on site as they extend out to provide sta

Engineering firm Ricardo is part way through a research programme to develop an advanced energy recovery system that can be integrated into an excavator’s hydraulic system. Known as the High Efficiency Excavator (HFX) project, the system uses a 5kg carbon fibre flywheel that is encased in a vacuum-sealed cartridge, which contributes to minimising friction. The flywheel is spun at speeds of up to 30,000rpm using a magnetic coupling, which is driven from a hydraulic motor. Power for the hydraulic motor comes
