European Overhead Crane:lightweight, safety and reliability

Brief Introduction of QDX Type Double Girder Overhead Crane

QDX type double girder overhead crane adopts European design. European-style double-girder overhead cranes are developed on the basis of traditional cranes. They have unparalleled performance advantages, compact structure, light weight, safety and reliability, and high operating efficiency. They are widely used in various industries. Due to the design advantages, the European double girder bridge crane can help you reduce the initial investment in factory construction, increase productivity, reduce daily maintenance workload, reduce energy consumption, and obtain a higher return on investment.

Advantages of QDX Double Girder Overhead Crane

Compared with traditional cranes, it has special features:

Small dimension, light dead weight;
Minimum approach dimensions due to compact traveling hoist design, that means from hook to the wall, the distance is smaller, so in the same workshop condition, the cross traveling distance can be longer;
Low headroom. it is a very low headroom design, which can increase the lifting height and save the workplace space, reduce the workshop construction cost;
Low vibration and noise design, reduce noise nuisance;
Working more stable and steadily, reduces the risk of the lifted product damage from crane wobbling.
Three-in-one motor, reducer and brake, speed controlled by frequency converter, more option for speed requirement. We can not only offer our own SZW brand but also ABM, SEW, and Simens brands.

Compared with single-girder cranes, it also has many advantages:

Increasing the lifting height: as the load hook can be raised between the two crane girders;
Bigger load capacity: 20-300 ton
Bigger Span: when the span is big, a double girder design will be more reasonable and safe for lifting work.

Double Girder Overhead Crane Projects

In May 2022, five QDX European-style double-girder cranes were delivered to a Swedish customer whose company mainly produces precast concrete components. These bridge cranes are designed with a span of 25 meters and a safe working load of 50 tons. We then delivered 2 more overhead traveling cranes with the same dimensions and technical characteristics. Several of the cranes have a service platform, allowing users to quickly and easily service and maintain the cranes. Multiple cranes and two identical electric wire rope hoists work in tandem to ensure the safe transport of large concrete elements within the plant and their safe loading onto trucks.

Why Custom a Crane Solution?

At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general factories, warehouses, etc. Besides, different applications have different needs for cranes. For example, steel industries often lift steel plates, so need electromagnetic cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need to grab bucket cranes. Chemical dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes.

So, we provide customized cranes according to the special needs of our customers. Custom crane solutions offer many benefits in a variety of applications：

Improve efficiency: Cranes can use automatic controls, and special accessories to improve efficiency.
Break space constraints: In limited spaces, standard cranes may not fit due to their size. Custom cranes can be designed as compact or lightweight cranes.
Cost savings: Customized cranes can lead to long-term cost savings. Customized crane solutions ensure crane's performance is all necessary for your business.
