Click to
zoom in


The Bromma Height Indication System – HIS, measures the distance between the spreader and the container.

It sends a signal to the crane to decelerate, helping the crane operator avoid a hard landing on the container. This can also help prevent slack rope, and reduce the wear and tear on the spreader.

Benefits of the upgrade


  • Reduced downtime
  • Increased productivity
  • Longer spreader life length as a result of less wear
  • Reduced maintenance need when hard landings are avoided

The HIS is available both as an option for new spreaders and as an upgrade on spreaders already in operation.
