Single girder overhead cranes with top running trolley

The GD ES type single-girder overhead crane with corner trolley is specifically designed to meet the challenges of crane operation in low-clearance industrial buildings. This latest development aims to maximize industrial efficiency and space utilization, especially in facilities where every centimeter counts for production or storage.

The key advantage of the corner trolley design lies in its ability to make the most of the available installation height, providing the highest possible top hook position. This translates into increased usable lifting height, which offers a significant competitive edge in environments with limited headroom yet demanding fast and efficient material handling.

One of the most notable innovations in the ES overhead crane is the elimination of hanging festoon cables. Instead, a sliding current collector system with a plastic housing ensures safe electrical power supply to the trolley. This design not only enhances aesthetics but also improves operational safety, reduces the risk of snagging, and minimizes maintenance requirements.

The crane is equipped with an industrial-grade chain hoist from Stahl Cranesystems, offering reliable, stable performance in the 1–6.3 ton load capacity range for daily industrial operations. Its robust and durable construction ensures a long service life, even under heavy-duty usage.

A major technical highlight is the low rolling resistance travel mechanism of the corner trolley, which transfers loads to the main girder via three running wheels, without any flange friction. All force transmission occurs through rolling elements, significantly reducing wear and extending service life while also minimizing the chance of failure. Compared to conventional trolley systems, this design drastically reduces operational costs.

The GD corner trolley overhead crane is not only cost-effective and space-saving, but also the result of intelligent engineering innovations that already meet the industrial needs of tomorrow.

Frequently Asked Questions

How does the ES type crane differ from traditional single-girder cranes?
The ES model features a unique corner trolley design developed by GD, allowing for the highest possible top hook position—especially valuable in low-headroom buildings.

What is the load capacity of this crane?
The crane is equipped with an industrial-grade chain hoist and supports load capacities ranging from 1 to 6.3 tons, ideal for daily material handling operations.

What is the advantage of the three-wheel corner trolley design?
All load transmission occurs via rolling elements, eliminating flange friction. This reduces wear and operational noise, increases durability, and significantly lowers maintenance costs.

How is power supplied to the trolley?
Power is delivered via an enclosed plastic conductor rail mounted along the main girder. This design eliminates the need for hanging festoon cables, enhancing safety and reliability.

Is this crane suitable for low-clearance facilities?
Yes, it is specifically designed to maximize lifting height in buildings with limited headroom, making it ideal for compact industrial environments.

Can this crane be adapted to different building structures?
Absolutely. The ES crane system is designed for flexible installation and can be customized to suit the layout of your production hall or warehouse.
