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.

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:
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.
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.
Single girder cranes can play an important role in many material handling operations, but, as with all heavy machinery, care must be taken to ensure that the proposed usage meets the appropriate application and does not exceed technical limitations.
