Double Girder Cranes

The industry standard for heavy duty lifting, double girder cranes are often seen in warehouses, workshops, factories, steel mills, railways, ports, and mining sites - a common sight in industrial and transport operations where a dedicated heavy lifting function is required.

Depending on the configuration and construction materials used, double girder cranes have a load capacity between 2,000kg to 200,000kg or more, and are designed as a custom overhead gantry crane system from the ground up.

What are double girder cranes used for?

Similar to their single girder crane system cousins, double girder cranes are often utilised to safely and efficiently transport heavy goods and materials such as steel, industrial machinery, shipping containers, and train and railway components.

Double girder cranes can be found throughout the heavy industry and transport sector, with operators including:

  • Logistical transport and warehousing hubs
  • Factories
  • Steelworks
  • Mining operations.

How does a double girder crane system work?

The dual or double girder crane is a precisely engineered overhead gantry crane lifting instrument with a three-dimensional construction to provide the most height possible by lifting from the bridge profile, located between the track profiles, maximising the hoist height and work space. With a double girder crane, the clearance height is increased compared to a single girder crane, as the hoist can run on top of the girders.

By giving you more room to manoeuvre within, a double girder crane provides greater safety for personnel and transported goods, and increases the efficiency of your material handling operation.

Advantages and disadvantages of a double girder crane system

Double girder cranes differ from their single girder crane counterparts in that they feature two girders in their configuration. These girders are metal beams from which the central lifting point of the crane (the hoist head) runs.

The girders used on such double girder crane systems are generally “I” profile beams, typically straight in their design with a distinctive “I” style construction. Girder beams can be reinforced throughout or at points to accommodate different loads and crane arrangements.

The key advantages of a dual or double girder crane system are:

  • Superior hoist/hook height compared to a single girder crane
  • Theoretically no limitations regarding maximum span or capacity rating
  • Special features such as maintenance walkways and platforms, cabs, lights, and magnetic reels can be supported by a double girder crane design
  • Suitable for indoor and outdoor use

The double girder setup typically offers greater lifting capability at the trade-off of higher material and freight cost, design complexity and additional challenges around installation compared to a single girder crane.

Our Process

On-Site Consultation

A Stratalign lifting specialist will respond to your enquiry promptly and arrange an on-site visit to assess your specific needs and obtain all technical data and dimensions etc. to suit your individual requirements.


Based on your criteria design engineers will prepare a customised lifting system design or present a combination of product recommendations that will resolve your lifting & materials handling challenges while meeting all safety and operational requirements.


Once you have approved the system design or product solution Stratalign coordinates production, assembly & procurement of all the components to ensure a seamless fulfilment of your valued order to meet your delivery or installation deadlines. This includes pre-delivery checking of all major mechanical or electrical items.


The Stratalign team’s service package doesn’t stop with delivery of your order. Experienced personnel will arrange to carry out the installation and set-up of your lifting solution and can even attend to foundation or structural modifications if necessary.


On completion of delivery & installation Stratalign representatives will commission the new machinery or equipment to ensure it is fully operational and that your team are familiar with all the features and capabilities that will take your productivity to new heights.
