Why you should implement your project with thyssenkrupp rothe erde

All over the world, cranes and lifting devices play a central role when it comes to safely transporting goods along increasingly demanding routes and in virtually any environment. Whether a wind turbine is being erected on the high seas, ships are being efficiently loaded and unloaded, or a skyscraper is setting new height records. The principle here is: bigger, faster and further, in conjunction with ever higher loads.

rothe erde® rings and slewing bearings have been reliable connecting elements for every crane and lifting device for decades, regardless of its purpose and size. They:

  • rotate smoothly,

  • withstand very high loads,

  • are protected from high friction, corrosion and wear by suitable lubricants,

  • increase the productivity of the application and

  • reduce maintenance and downtime of the application due to their long service life.

If required, the bearings can also be monitored in the installed condition using specially developed test systems. With to our self-developed condition monitoring systems, remote monitoring is digitally possible even for applications that are difficult to access. This enables targeted maintenance to be carried out and downtimes to be avoided.

Together with our customers, we develop technical solutions that meet even the most unusual requirements and at the same time provide them with an economic advantage.

Our products are used in these cranes and lifting devices

Deck cranes

  • As the ship's own loading gear, deck cranes load and unload goods from cargo ships with a very high lifting capacity. Here, robust slewing bearings are in demand. They guarantee the swivel capacity of a deck crane under adverse maritime conditions: whether at irregular intervals with heavy loads or during high periods of operation when handling lighter and mid-sized loads.
  • Typical products: Four-point bearings, double four-point bearing, three-row cylindrical roller bearing, double-row ball bearing slewing ring, four-row cylindrical roller bearing, blanks, machined rings

Handling cranes / shipyard cranes

  • In port operations, handling and shipyard cranes are an essential support in transporting products, goods, and parts. These cranes are often rail-bound and characterized by their reliable technology and high durability. Since our bearings can withstand even the highest demands and loads, they have already been used around the world for several years.
  • Typical products: four-point bearing, double four-point bearing, three-row cylindrical roller bearing, double-row ball bearing slewing ring, blanks, machined rings

Lifting platforms

  • In the crane segment, lifting platforms represent a special variant. They are primarily used to lift people to places that are difficult to access. Whether the use is intended for mobility outdoors, on roofs, over shafts or in construction sites: The security aspect plays a central role. Our components combine cost-effective designs with high precision, which are characterized by a high safety factor.
  • Typical products: four-point bearing, slew drives, profile bearing, double-row ball bearing slewing ring

Rotating crossbars / container spreaders

  • The operation sites for crossbars are very different. These include production halls, factory premises, logistics centers and container terminals, amongst others. Resilient and powerful components are needed to transport the relevant goods. We offer specially designed slewing bearings and rings for different requirements. In addition, we also deliver reliable and cheap standard models suitable for several deployment scenarios.
  • Typical products: four-point bearing, double-row ball bearing slewing ring

Mobile cranes / truck-mounted cranes
