What do our customers say?

A 400-tonne crawler crane, that's exactly what we've been waiting for.


New assembly features

The complete assembly is remote-controlled and can be done in less than a day.

  • Assembly
    The self-assembly system allows safe and independent assembly/disassembly of all main parts (e.g. self-assembly of hoist winches using the A-frame).

    Operating modes

    Pre-selection is the key. The drivers can concentrate on their work, the crane takes care of its environment.

  • Wind speeds
    Pre-select one of the four wind speeds and the crane control automatically selects the permissible load curve (10, 12, 14 und 16 m/sec).
