Double Girder Overhead Cranes, Running Cranes

The GD ES-type single-girder overhead crane with corner trolley provides an efficient solution to the lifting challenges faced in industrial buildings with low ceiling heights. This is our latest innovation aimed at optimizing industrial efficiency and space utilization in environments where every centimeter matters for production or storage.The biggest advantage of the corner trolley configuration is its ability to maximize the available installation height, ensuring the highest possible top hook position. This results in increased effective lifting height, providing a significant advantage in areas with height restrictions while still requiring fast and efficient material handling.One of the key innovations of the ES overhead crane is the complete elimination of hanging festoon cables. Instead, a plastic-encased conductor rail system supplies electrical power to the trolley in a safe and compact manner. This solution enhances not only aesthetics and safety, but also reduces the risk of snagging and minimizes maintenance requirements.The crane is equipped with a high-quality chain hoist from Stahl Cranesystems, offering reliable and stable operation in the 1–6.3 ton capacity range for daily industrial applications. Its rugged construction guarantees a long service life, even under intensive use.A standout technical feature is the low-rolling-resistance trolley drive, which transfers load through three running wheels to the main girder with zero flange friction. All forces are transmitted via rolling elements, significantly reducing wear, extending service life, and minimizing the risk of failure. Compared to conventional systems, this design drastically reduces operating costs.

The GD corner trolley overhead crane is not only cost-efficient and space-saving, but also the product of intelligent engineering, meeting tomorrow’s industrial requirements today.

If you are looking for a solution that delivers maximum performance in minimal headroom, the GD ES-type corner trolley crane is your ideal choice. Contact us today for a personalized quote, and harness the full benefits of technological innovation in material handling!

Frequently Asked Questions

How does the ZL type crane differ from conventional overhead cranes?
ZL cranes feature two main girders, providing enhanced load capacity and structural stability—ideal for lifting heavier loads and covering larger spans.

What load capacities are available?
The system is available in configurations ranging from 1 to 50 tons, customized to suit the customer’s specific industrial application.

What are the advantages of a top-running crane design?
The crane runs on rails mounted above the girders, enabling maximum lifting height and full utilization of the building’s interior space.

What kind of hoisting mechanism is used?
We equip our cranes with premium-quality hoists from Stahl Cranesystems, available in both wire rope and chain versions based on the load and application.

What configuration options are available for the ZL series?

ZL-A: Low structural height with increased load capacity
ZL-B: Low profile design with optimized hook end positions
ZL-C: Designed for maximum lifting height

Can the crane system be adapted to our facility’s layout?
Yes, our crane systems are fully customizable and can be adapted to the structural layout of your building, whether using existing runway beams or new support columns.
