Single Girder Cranes

With an ergonomic and cost-effective design, single girder cranes are a comparatively lightweight type of overhead gantry crane, ideal for lifting operations in locations which require a dedicated lifting capability from a fixed crane system.

Single girder cranes are precisely engineered, robust overhead crane systems. Featuring a three-dimensional construction, a single girder crane operates by lifting from the bridge profile, located between the track profiles, maximising the lifting height and working space.

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

What are single girder cranes used for?

Whether suspended from the roof with standard suspensions or mounted on the floor with freestanding support frames, single girder cranes are commonly found in industrial environments where a dedicated lifting capability is required.

Single girder cranes are utilised to safely and efficiently transport heavy goods and materials such as steel, industrial machinery, or mechanical components.

Several locations where single girder cranes can commonly be seen include:

  • Automotive workshops - particularly useful in the removal of engines
  • Factories
  • Steelworks
  • Engineering and fabrication workshops.

What is the “girder” on a single girder crane?

A single girder crane features only one girder in its configuration - the girder being the metal beam on which the central lifting point of the crane (the hoist head) runs.

The girders used on such cranes are "I" profile beams, meaning they are typically straight and feature an "I" style construction which can be reinforced throughout or at points to accommodate different loads and crane arrangements.

What is the difference between a single girder crane and a dual girder crane?

As implied by the name, single girder cranes differ from dual (double) girder cranes in that they feature a solitary metal beam girder in their design. This single girder configuration results in a reduction in materials and engineering design, making the single girder crane a cost-effective and comparatively lightweight lifting solution when weighed up next to a dual girder crane.

Single girder cranes are often designed to be somewhat portable, making them easier to install and transport than dual girder cranes - though this is determined on a case by case basis, depending on the structural design and material composition of the crane system.

This single girder design is a double edged sword, as the reduction in structural material and relative design complexity of a single girder crane system means that the total span and capacity rating is likely to be lower, with special features like lights and maintenance components such as service walks often more difficult to incorporate than on a dual girder crane system.

Dual girder cranes feature two metal beam girders. This dual girder setup usually 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.
