A Double Girder Overhead Crane is a heavy-duty lifting solution designed for large workshops, steel mills, power plants, mining facilities, and industrial production lines. With two strong bridge girders and a high-performance trolley winch, it delivers high lifting capacity, excellent stability, and long-term reliable operation. As one of our main lifting solutions, the double girder overhead crane belongs to NYBON’s complete range of overhead crane systems for industrial applications.

NYBON Machinery offers a complete range of double girder cranes, including QD type, European type, foundry cranes, grab cranes, explosion-proof models, and other customized solutions.

Types of Double Girder Overhead Cranes

QD Type Double Girder Overhead Crane (Standard Heavy-Duty Model)

The most widely used double girder crane for general heavy lifting tasks.

  • Capacity up to 450 tons

  • Stable and durable structure

  • Suitable for steel mills, machinery workshops, and logistics centers

  • Pendant control, remote control, or cabin operation available

Heavy Duty Overhead Crane Double Beam Electric Hoist

European Type Double Girder Overhead Crane (FEM/DIN Standard)

A premium crane with a lightweight structure and advanced performance.

  • Smooth operation with frequency inverter

  • Compact trolley reduces building height

  • High lifting accuracy and low noise

  • Suitable for modern manufacturing plants

LH A5 Double Beam Overhead Crane

LH A5 Double Beam Overhead Crane

  • Compact Design: It features tight dimensions, low building headroom, and light dead weight (or light wheel load), making it cost-effective and space-saving.

  • Lifting Capacity: The typical lifting capacity ranges from 5 tons to 50 tons (though custom options up to 100 tons exist).

  • Span: Standard spans typically range from 10.5 meters to 31.5 meters.

  • Lifting Mechanism: Uses a fixed electric wire rope hoist as the lifting mechanism, which runs on double girders.

  • Application: Ideal for medium-duty work environments like machining workshops, warehouses, assembly plants, and power stations (A3-A5 working class).
