INTRODUCTION
What is this?
The double beam gantry crane is a gantry crane featuring a double main beam structure. Through the coordination of hoisting and traveling mechanisms, with legs running on ground rails, it achieves precise lifting and handling of heavy materials, large equipment, containers, steel structures, and more. If you are looking for a crane with strong load capacity, long span, and high stability for a port terminal, railway freight yard, shipyard, stockyard, or large manufacturing workshop, this product is designed for you.
Why choose a double beam gantry crane over a single beam gantry crane?
Compared to single beam gantry cranes, the double beam gantry crane 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 18 meters to over 50 meters, covering wider stockyards and working areas.
Third, smoother operation – minimal deflection of the double girder structure provides smoother trolley travel and more precise positioning, suitable for precision lifting operations.
Fourth, wider application – compatible with various lifting attachments such as main/auxiliary hooks, magnets, grab buckets, and spreaders to suit diverse operational needs.
Take on heavier tasks with a stronger 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 over 500 tons; span from 18 meters to 50 meters; leg types of A-frame, L-frame, or U-frame; single or double cantilever; control options of cabin, remote radio, or pendant; VVVF speed control optional. Whether your working environment is an outdoor stockyard or an indoor workshop, we can match the most suitable span and lifting height.
Unsure? Don't know?
Not sure whether to choose A-frame or L-frame legs? Don't know what span can cover your stockyard? No problem. Just tell us: your maximum lifting capacity, your stockyard span or width, whether you need cantilevers, and whether it's for outdoor or indoor use. Our engineers will provide you with an accurate quote and CAD drawings within 24 hours. Click the button below or contact us via WhatsApp/email to get your customized solution.
