INTRODUCTION
What is this?
The QDxx European standard bridge crane is a double-girder overhead crane designed and manufactured according to FEM/ISO European standards. It features a compact box-section main girder structure with an electric wire rope trolley, achieving precise lifting and handling of heavy materials, molten metal ladles, large equipment, steel coils, and industrial machinery. If you need a high-performance, space-saving overhead crane that meets international standards for heavy industrial applications, this product is designed for you.
Why choose a QDxx European standard bridge crane over a traditional QD Chinese standard bridge crane?
Compared to traditional QD Chinese standard bridge cranes, the QDxx European standard solution offers four core advantages:
First, smaller headroom – optimized FEM design reduces hook approach distance and deadweight by 15%-25%, maximizing effective lifting height under the same building clearance.
Second, lighter self-weight – precision-engineered box girders with FEA optimization reduce overall crane weight, lowering workshop rail and building load requirements.
Third, smoother operation – European standard components with higher precision tolerances provide smoother start/stop and more accurate load positioning.
Fourth, lower energy consumption – IE5 permanent magnet synchronous motors with energy feedback VFD drives reduce power consumption by 25%-35% compared to traditional designs.
Achieve more lifting height with a more compact European design.
What can we do for you?
We understand that every customer has different building structures, different capacity requirements, and different working conditions. Therefore, we offer flexible customization options: lifting capacity from 5 tons to 100 tons (up to 500t available); span from 10.5 meters to 31.5 meters; main/auxiliary hook ratios such as 20/5t, 50/10t, 100/20t; control options of cabin, remote radio, or pendant; VVVF speed control for smooth start/stop. Whether your workshop is for general manufacturing or heavy steel melting, we can match the most suitable span and lifting height.
