Contrx double girder bridge cranes are used when capacity and span requirements are too great for a single girder crane to be used. Double girder cranes also provide higher hook heights because the hoist is placed between the cross girders as opposed to under the cross girder. Double girder cranes are also excellent solutions for handling large loads with long spans. Full length walkways can also be provided for easier servicing of the crane. Double girder cranes support CMAA Class C, D, E, F, Mill Duty Hot Metal and Magnet applications. Contrx bridge cranes are fabricated by AWS D1.1 and D14.1 certified welders.
