    • Optional remote monitoring modem
    • Smart functions

  • Smart Features

    More comfort and safety

    • Anti-sway control
      Prevents increased load sway by active counter-motions of the crane.
    • Slack-rope prevention
      Continuous monitoring of the rope tension. Reduces the risk of damage to the load, crane and surrounding area.
    • Area-specific load reduction
      Areas can be defined which the travelling hoist may only enter if the load does not exceed a reference value.
    • Bypass control
      Areas to be blocked for the travelling hoist can be specified.
    • Tandem control
      Loads can be safely transported by two DVR rope hoists – via a single control unit.

    DMC Demag Modular Control

    • Follow me
      The crane can be moved above the load by simply guiding the hook by hand. (Recommended for cranes up to 10 t)
    • Hook Centering
      Faster load cycle times: Positions the crane hook automatically directly over the load
    • Smart Tandem control
      Two cranes with up to four rope hoists can also be synchronized
