INTRODUCTION

The QDxx European Standard Bridge Crane is an advanced, heavy-duty double girder overhead crane built in strict compliance with FEM / DIN / ISO standards. Engineered with an open winch hoisting trolley running on top of twin box girders, the QDxx series represents the modern European-style evolution of traditional QD cranes—delivering maximum lifting capacity with a compact, low-headroom design.

APPLICATION SCENARIO

[1] Heavy Machinery Workshops – Handling large machine parts, engine blocks, press frames, and heavy industrial equipment.

[2] Steel Melting Shops – Lifting and transporting molten metal ladles, scrap charging buckets, and slag pots with heat-resistant components.

[3] Equipment Assembly Plants – Moving transformer bodies, generator rotors, turbine sections, and mining equipment parts.

[4] Steel Service Centers – Loading/unloading steel coils, plates, pipes, and structural sections from trucks and storage racks.

[5] Industrial Manufacturing Facilities – Handling large molds, dies, castings, and finished heavy products in general manufacturing.

ADVANTAGES

[1] Compact European Design – Smaller headroom and hook approach maximize lifting height in limited building clearance.

[2] High Load Capacity – Double girder design supports loads from 5t up to 500t, meeting heavy industrial requirements.

[3] Energy Efficient – IE5 permanent magnet motors with energy feedback reduce power consumption by 25%-35%.

[4] High Duty Cycle – Designed for continuous operation with duty class up to A8, suitable for intensive 24/7 use.

[5] Global Compliance – FEM/ISO certification simplifies export and use in international projects.
