INTRODUCTION
What is this?
The QD double girder overhead crane is a heavy-duty lifting solution featuring a double main beam bridge structure. Through the coordination of an electric wire rope trolley with main and auxiliary hooks, combined with crane traveling mechanisms, it achieves precise lifting and handling of heavy materials, large equipment, steel coils, molten metal ladles, and industrial machinery. If your workshop requires high load capacity, long span, and continuous heavy-duty operation, this product is designed for you.
Why choose a QD double girder overhead crane over a single girder overhead crane?
Compared to single girder overhead cranes, the QD double girder solution offers four core advantages:
First, stronger load capacity – the double main beam structure provides lifting capacity from 5 tons to over 500 tons, meeting heavy material and large-capacity lifting requirements.
Second, longer span – higher structural rigidity of the double girders allows spans from 10.5 meters to over 31.5 meters, covering wider workshop areas.
Third, higher lifting height – the trolley runs on top of the girders rather than hanging below, maximizing effective lifting height under the same building clearance.
Fourth, wider application – compatible with various lifting attachments such as main/auxiliary hooks, magnets, grab buckets, ladles, and spreaders to suit diverse operational needs.
Take on heavier tasks with a stronger double girder structure.
What can we do for you?
We understand that every customer has different capacity requirements, different spans, and different working environments. Therefore, we offer flexible customization options: lifting capacity from 5 tons to 500 tons; span from 10.5 meters to 31.5 meters; main/auxiliary hook ratios such as 20/5t, 50/10t, 100/20t, 200/50t; control options of cabin, remote radio, or pendant; VVVF speed control for smooth start/stop. Whether your workshop is for general manufacturing, heavy steel melting, or precision assembly, we can match the most suitable span and lifting height.
Unsure? Don't know?
Not sure what capacity suits your daily workload? Don't know what span fits your workshop width? Need a main/auxiliary hook combination? No problem. Just tell us: your building clearance height, your workshop span, and the maximum weight to be lifted. Our engineers will provide you with an accurate quote and CAD drawings within 24 hours.
