DOUBLE GIRDER SEMI GANTRY CRANE

INTRODUCTION to Double Girder Semi-Gantry Crane:

Semi Gantry Crane is developed on the basis of gantry crane. It’s a kind of light type crane, commonly used in modern production. In workshops where part utilization of shop bay is required, 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. Compared with the electric single-girder gantry crane, it can save the investment and space.
