Crane modernisation: from semi-gantry to gantry

Renovation, technical refitting and certification of a semi-gantry crane at the ArcelorMittal Madrid plant into a gantry crane for the Differdange plant in Luxembourg


The world’s leading steel and mining producer needed a gantry crane for handling long products at its plant in Luxembourg.


JASO, given the client’s requirements, came up with a solution involving the conversion of a 5 ton, 2 x 12 semi-gantry crane previously installed in ArcelorMittal’s Madrid plant, into a gantry crane suited to the Differdange plant’s needs.

Therefore, we developped a turnkey project, including analysis and removal of the crane in Madrid, moving it to JASO’s workshops, manufacture of the structural parts, the preparation of all mechanical and electrical components, as well as checks of weldings and the state of the components.

In addition, we have provided the appropriate training and practice for the staff at the Luxembourg plant for the proper use and operation of the equipment, with emphasis on everything related to staff safety.  

For every turnkey project, JASO takes responsibility for transport, unloading, assembly and adjustment at the customer’s premises, and offers support during the certification process by the accredited body. And once the project is completed, we guarantee the best after sales service to be closer and closer to our customers.
