Hitachi Construction Machinery (Europe) (HCME) says its new ZW250-5 wheeled loader being unveiled at bauma is the result of feedback from European customers. The model’s cab is said to be more spacious than models from the previous range, because the heated air-suspension seat can slide further back, providing more leg room. The tilting telescopic pop-up steering column has also been repositioned to create additional space. An air conditioning system has been installed that regulates the temperature inside

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
