In workshops where part utilization of shop bay is required (as in a tool room attached to a press shop), a Semi Gantry Crane is used. In such a configuration, one end-carriage of the crane will travel 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. These cranes can be installed for various applications such as Grabbing in Steel Plants, Manufacturing Units and Stock Yards etc.
