Overhead Crane

Single & double girder bridge cranes, 1–500 tons

The overhead crane (bridge crane) is our core product. It travels on elevated runway beams to lift and move loads anywhere within a rectangular working area. We build both single girder (LD) cranes for light and medium duty and double girder (QD) cranes for heavy, high-frequency operation.

Every crane is engineered to your capacity, span, lifting height and duty cycle, to FEM, DIN, ISO or GB standards, with options including cabin, pendant or wireless radio control, anti-sway, weighing and overload protection.

Overhead Crane — frequently asked questions

What capacity is the Overhead Crane available in?

The Overhead Crane (LD / LDA / QD Single & Double Girder) is built in capacities from 1 – 500 t, with spans of 7.5 – 40 m and lifting heights of 6 – 40 m. Every unit is engineered to your exact figures rather than supplied from a fixed range.

What is the Overhead Crane used for?

Overhead bridge cranes in single girder (LD) and double girder (QD) configurations, 1–500 tons, custom-engineered to your span and duty cycle. Typical applications include machine shops and fabrication, warehouses and logistics, steel and metallurgy, assembly and production lines.

What duty class does the Overhead Crane support?

The Overhead Crane is available in duty class A3 – A7 (FEM 1Am–4m). Duty class is selected from your load spectrum and daily operating hours — tell us how the crane will be worked and we will size the mechanism accordingly.

What control options are available for the Overhead Crane?

Control options are Cabin / pendant / radio remote. Variable frequency drives, anti-sway, weighing and overload protection can be added on request.

Can the Overhead Crane be customised to my site?

Yes. Capacity, span, lifting height, duty class, power supply, control method, paint system and protection class are all specified per project, to FEM, DIN, ISO or GB standards. Send us your site conditions and we will return a configuration and a quotation within one business day.
