At present, Dongqi Crane can provide customers with cranes with a maximum lifting capacity of 500 tons. If customers need a crane with a higher lifting capacity, they can submit their requirements to us and our engineers will solve it. The case shared by Dongqi Crane today is a custom-made bridge crane with a lifting capacity of 140 tons for a wind turbine supplier in Denmark. By analyzing the design and installation process of the crane, Dongqi Crane can accumulate more practical experience. If any customers have similar needs, they can communicate with us closely.

The bridge crane built by Dongqi Crane focuses on the three major elements of efficiency, safety and stability in design. Efficiency is reflected in its excellent lifting capacity and fast work efficiency. Whether it is heavy equipment or bulk materials, the bridge crane can easily handle it, greatly improving the production efficiency of the manufacturing industry. Safety is guaranteed through careful structural design, high-quality materials and strict manufacturing processes to ensure stable operation during operation and avoid accidents. In terms of stability, the bridge crane adopts advanced control systems and balancing devices to maintain stable operation in various complex environments.

The process of customizing an overhead crane from a wind turbine supplier to a crane supplier

Danish Crane Manufacturing, headquartered in Nieber, Denmark, offers overhead cranes, jib cranes, wire rope hoists, chain hoists and gantry cranes as part of an extensive standard range.

The Danish crane manufacturing company claims it has global level expertise in the manufacture of nacelle cranes developed for shipyards around the world, as well as robotic cranes for power plants, waste incineration, dairy plants and more.

The company believes it is one of the only companies in Denmark with facilities capable of designing, planning and manufacturing overhead cranes entirely in-house.

The unit is designed to handle specific heavy-duty components and was made possible by a collaboration between a French crane manufacturer and a Danish crane manufacturer.

Due to the heavy requirements and complexity of the project, the two companies collaborated to develop equipment suitable for the job.

Kristen Jensen, technical director of Danish Crane Building, explains the use of the heavy-duty overhead crane, which will produce wind farm components at the Lyndao Industrial Park and ship them around the world.

"The scale of the wind farms currently being developed requires production and transportation facilities on a global scale. These facilities are already located at Lindao Industrial Park and the delivery of the new cranes further expands the already impressive production capacity of the industrial park," said Jensen. The rapidly growing wind power industry increasingly requires components that are much larger than before. The facility has double its original capacity, Jensen said.

“We doubled the total lifting capacity of the building where the crane is installed.”

The load of the crane provided was so heavy that changes had to be made to the structure of the building housing it.

"The upgrade required strengthening the building structure, and these issues were resolved in close collaboration with the crane experts at Crane Building in Denmark. The end result was a robust solution that met the client's expectations," said Jensen.

The new heavy-duty overhead crane at Lindao Industrial Park has a total weight of more than 75 tons, including pulleys, drive gears, steering gear and all components.

Excluding pulleys and other lifting devices, the installation weight is only over 50 tons.

Overhead cranes of this weight and size are primarily manufactured for large power plants and heavy industry where extremely heavy modular equipment such as generators need to be lifted.

The company said the Danish electricity market for heavy-duty overhead cranes is a relatively modest one, although one with significant future growth potential.

“Our lifting capacity has now increased to 250 tonnes, with single spans up to 40m.”
