Service Bridge Crane for the
handling of troughs and tundishes
in the Global Steel Wire steel mill
at its plant in Santander.
This bridge crane will have a capacity of 55t and
a span of 28m, with the special characteristic
of benefiting from redundancy, both in terms
of mechanical components
(which allows it to continue
working in the event of failure
of one of its motors) and
electrical components (double
frequency converter for each
of the movements).
All the components have been
designed and manufactured
to withstand the toughest
working conditions in a steel
mill at high temperatures.
