What is a single girder overhead crane?
A single girder overhead crane is a crane with a lifting trolley (hoist) running on one main girder. The bridge travels on a runway resting on the building columns or corbels, and the hoist runs on the lower flange of the girder, so loads can reach every point of the bay. It is built to order from 1 to 16 tons for light and medium loads.
Why a single girder overhead crane?
Compared with double girder systems:
- Lower investment cost: more economical.
- Lighter steel structure and lower column loads: the building and runway can be lighter.
- Quick installation: shorter installation time.
- Low maintenance cost and energy efficiency.
Areas of use
- Production plants
- Machine manufacturing workshops
- Steel construction factories
- Warehouses and logistics areas
- Energy and heavy industry plants
Single girder crane components
- Bridge girder: a single box or I-beam main girder.
- End carriages: at both ends of the bridge, travelling on the runway with their wheels and drive motors.
- Hoist trolley: electric wire rope or chain hoist running on the lower flange.
- Runway: girder and rail resting on columns or corbels.
- Power and controls: busbar or cable power supply, control panel, pendant or remote control.
- Safety: limit switches, overload protection and emergency stop.
Options
- Inverter speed control
- Radio remote control
- Runway and columns included in the project
- Equipment suited to dust, heat or outdoor conditions
Single girder crane prices
Single girder crane prices depend on:
- Capacity
- Bridge span
- Lifting height
- Duty class
- Ambient conditions (dust, temperature, etc.)
- Whether a runway is also needed
You can request a free site survey and quotation for a firm price.
When choosing
- Capacity: add the weight of the hook, slings and attachments to the heaviest load.
- Bridge span: the distance between the centres of the two runway rails (standard 3 – 20 m).
- Lifting height: the highest point the hook must reach and the clear height of the bay.
- Supporting structure: are there columns or corbels? If not, the runway and columns are added to the project.
- Intensity of use: daily operating time and number of lifts set the duty class.
If heavy loads, wide spans and high lifting heights are needed, a double girder overhead crane is the better choice.

Frequently asked questions
How many tons does a single girder overhead crane lift?
Standard systems are built from 1 to 16 tons. Custom designs are possible for the project.
How does it differ from a double girder system?
The single girder system is more economical and preferred for lighter loads. For heavy loads and wide spans, a double girder system is recommended.
What is the maintenance interval?
Maintenance is recommended about every 6 months, more often under heavy use. In addition, lifting equipment must legally be inspected at least once a year.
What information is needed for a quotation?
Capacity, bridge span, bay length, lifting height, whether there is a runway, intensity of use and site location.
