Single Girder Suspension Cranes

Single-girder suspension cranes, also known as under-running cranes (EH), offer an exceptionally economical and flexible material handling solution for industrial environments where space utilization is a top priority. These crane systems run directly on crane tracks attached to the building’s ceiling girders, which can result in significant cost savings, as there is no need for separate support structures or columns. This makes them especially advantageous for applications with lower load capacities or where maintaining an unobstructed floor area is essential.

One of the key benefits of suspension cranes is their ability to cover the full width of the building, while their cantilevered design allows the hoist to travel into adjacent bays or areas. This configuration not only maximizes usable space but also supports flexible material transfer between work zones, which is particularly valuable in interconnected production lines or complex warehousing systems.

It is important to note that for higher loads or wider spans, the ceiling structure would require substantial reinforcement to bear the crane’s weight, leading to increased costs. Therefore, these systems are typically built with load capacities of up to 10 tons, a range in which they deliver outstanding performance combined with excellent cost-efficiency.

GD’s suspension cranes are equipped with premium-quality components from Stahl Cranesystems GmbH, ensuring reliable operation, easy maintenance, and precise control over time. Available options include:

• Chain hoists with capacities of up to 6.3 tons
• Wire rope hoists tailored up to 10 tons

Drive systems can be fully customized to suit client needs, including two-speed drives for both fast and fine movements, and variable frequency drives that enable high-precision positioning – essential for handling delicate loads or operating in manufacturing environments that demand accuracy.

At GD, our mission is to deliver custom-tailored crane systems that perfectly match your company’s production processes and infrastructure. Our single-girder suspension cranes significantly improve operational efficiency while delivering long-term cost savings.

Frequently Asked Questions

How do suspension cranes differ from traditional overhead cranes?
Suspension cranes run on tracks attached directly to the ceiling structure, eliminating the need for columns or floor-mounted supports. This saves space and reduces overall installation costs.

What load capacities are available for these cranes?
Depending on the configuration, these systems can be equipped with chain hoists up to 6.3 tons or wire rope hoists up to 10 tons.

What types of buildings are suitable for this crane type?
They are ideal for industrial halls and production areas where floor space must remain clear, and the lifting requirements are moderate. Especially useful in warehouses, assembly areas, or facilities with connected production lines.

Does the building structure need reinforcement?
Yes, for higher loads or longer spans, the ceiling structure must be reinforced to support the crane. For lighter applications, the existing structure is often sufficient.

What control options are available?
The cranes can be equipped with two-speed drives for fast and slow movement or with frequency-controlled drives for smooth and precise handling—especially important for delicate loads.

Can the crane reach adjacent work zones?
Yes, thanks to the cantilevered design, the hoist can travel beyond the edge of the crane runway into neighboring areas, enabling seamless transfer between zones.
