LD Electric Single Girder Overhead Crane

▪ LD Electric single girder overhead crane (LD Electric single beam bridge crane ) is one type of light duty crane, can be used with Wire Rope Electrical Hoist or Chain Electrical Hoist or Manual Hoist. Choose the overhead crane according to the users requirement and the overhead crane working environment. For example, if you want to buy the crane to be used in the workshop and the workshop which has been finished, we can design the overhead crane according to the workshop size to make sure successful installation.
