Double Girder Gantry Crane
Double girder gantry crane is ideal for outdoor applications where lifting facilities are provided without the cost ofa building or any supporting steel work. They are also suited to indoor applications where existing building structures are not suitable to take overhead cranes, JCYC Crane can be constructed with a cantilever to allow handling outside the rail centers.
