Play it safe!

Portal cranes are overhead cranes that stand firmly, are mobile on wheels (RTG) or operating via rails (RMG). They are preferably used for loading containers in port facilities.

The overload protection systems from Hirschmann MCS monitor by means of force measurement technology the overloading of containers as well as also disbalances of imbalanced loads. Also interlocking and collisions are prevented, with slack rope indication being displayed. The systems comply with the standards EN 15011/EN 13849/EN 62061 and EN 61508.
