The Double Girder Semi Goliath Cranes move on rails supported on floor level instead of rails placed at an elevated level as in the case of EOT Cranes

Double Girder Semi Goliath Cranes is a variation of a Gantry crane in which one end carriage of the crane travels on the regular gantry rail while the opposite end carriage will travel on a rail-mounted typically on the ground or at a lower elevation. A semi Gantry crane is used in applications such as a tool room where part utilization of the bay is required, or in outdoor sites where a gantry rail can be installed on the side of an existing structure.
