ET90 - Conventional Tail Excavator

  • Information

    The fuel consumption of the ET90 is up to 20 percent lower than with comparable models – this reduces the operating costs significantly. At the same time, it scores in applications with an excellent engine and hydraulic performance. This efficient combination provides for first-class digging power with up to 20% more bucket breakaway force. Conversely, the economical load sensing hydraulic system allows for finely controllable lifting arm movements with a full performance at the same time. Whether power or precision – the ET90 is exactly the right excavator for any application.

  • Information

    • Precise and sensitive operation thanks to the load sensing hydraulic system with LUDV (load-independent flow control)*
    • Low consumption due to the economical ECO mode
    • Up to 5 auxiliary control circuits for the most varied attachments
    • Extremely compact and maneuverable
    • Maintenance and service made easy due to the tiltable cabin as well as the diagnostic tool
