ZF chooses radial motor technology for its hydrostatic transmission

ZF has chosen a pair of radial hydraulic motors for use in its compact single-speed hydrostatic transmission, the 2HC85, which has been developed for compact wheeled loaders up to 100kW and 10.5tonnes operating weight. For high-torque start-up, the transmission sends oil to both motors and demands maximum stroke to travel from 0-16kph, before isolating one motor and then using 100% oil flow through the remaining motor to propel the machine to its maximum travel speed of 42kph.

Two five-piston radial motors are used in ZF’s 2HC85 transmission
2304 ZF has chosen a pair of radial hydraulic motors for use in its compact single-speed hydrostatic transmission, the 2HC85, which has been developed for compact wheeled loaders up to 100kW and 10.5tonnes operating weight.

For high-torque start-up, the transmission sends oil to both motors and demands maximum stroke to travel from 0-16kph, before isolating one motor and then using 100% oil flow through the remaining motor to propel the machine to its maximum travel speed of 42kph.

ZF said radial motors afford a lower working speed range within the transmission and create a more compact package compared to axial motors, which leads to greater installation options and a low working noise level compared to traditional hydrostatic transmission designs.

    Following the success of its 8MCR high-speed compact excavator, Mecalac has developed a larger, heavier model, called the 10MCR. Like the smaller machine introduced in 2009, this new model combines the speed and manoeuvrability of a skid steer loader with the functionality of a midi excavator. Weighing in at nine tones and using a 75kW turbocharged diesel engine, the new model retains Mecalac’s MCR concept and uses a triangular track frame profile, which affords fast travel speeds in both directions usin

    April 18, 2013
    Komatsu has unveiled its 23,590kg operating weight WA470-7 wheel loader, which offers improved efficiency, lower fuel consumption, improved operator comfort and enhanced serviceability. It is powered by a 203kW Stage IIIB/ EPA Tier 4I Komatsu SAA6D125E-6 engine, which is said to lower fuel consumption by 10% to 15% compared with the WA470-6. The engine is fitted with EGR, a hydraulically-actuated variable geometry turbocharger, and an automatically regenerating DPF. As with all Komatsu Stage IIIB machines,

    January 6, 2017
    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
