Double Girder EOT Crane is one of the configurations of the double Girder overhead crane,it’s a lifting equipment that is horizontally suspended above workshops, warehouses, and material yards for material lifting.Compared with single girder EOT crane, it has a larger load-bearing capacity and is more suitable for smelting workshops and intelligent control workshops.It is mainly consists of 5 parts: main beam(2 pcs,European style), end beam, electric hoist, electric control system and running rail.

Double Girder EOT crane is one of the configurations of the double Girder overhead crane, is widely used in heavy lifting scenarios (typically with a load capacity of over 20 tons). Although its cost is higher than that of single girder EOT cranes, many customers still choose to purchase double girder EOT cranes with a rated load of 5 tons.
Double Girder EOT crane are mainly divided into two types: LH type and QD type, corresponding to different hoisting mechanism configurations respectively. Among them, the LH type is equipped with a electric hoist type lifting mechanism (suitable for M3 to M5 working levels), while the QD type adopts a winch/trolley lifting mechanism (suitable for M5 and above working levels).
