Double girder overhead cranes are used when capacity and span requirements are too great for a single girder crane to be used. Double girder overhead  cranes also provide higher hook heights because the hoist is placed between the two cross girders rather than below (under the cross girder), this adds up to 3 feet more for the items lifted off the floor. Double girder overhead cranes are also excellent solutions for handling large loads with long spans. Full length walkways can also be provided for easier servicing of the crane.

             Double girder overhead crane consists of two end trucks with gear motors, two bridge girders, trolley hoist unit (or electric winch), electric panel, push button  station, which include safety equipment of cross bar limit switches, overload limiter, siren light, etc. In these components, bridge girders (main girder) are beam or box, trolley hoist is double girder, festoon flat cable power supply  system or energy chain supply power of the hoist, trolley or festoon flat cable  power supply system supply power of the crane, two-speed motors on lifting  and travelling mechanisms or stepless speed control by means of  frequency inverters, and 3 types of control for you choose: independent  overhead control box with buttons, or remote radio control, or cabin. What’s  more, in order to ensure the high-quality of our double girder overhead cranes, the parts all adopt from well-respected names. We provide maintenance and  operating pamphlet to our customers, which makes our overhead cranes become easy to hand and easy to change the parts.
