A supporting girder crane (single-girder overhead crane) is a metal structure consisting of a main (bearing) girder connected to two end girders on which the bogies are fixed. The lifting function in the girder crane is performed by a hinged electric or manual hoist.
Supporting crane beams are designed for lifting and moving various cargoes along the I-profile monorail track (with the exception of acids, molten and hot metal, poisonous substances); mass within the rated load capacity. Beam cranes are designed for indoor use or under a canopy at ambient temperatures from -40 ° C to + 40 ° C. These girder cranes can be used in almost all areas of industry for moving light and medium intensity loads with 3K and 5K operating modes.
