Overview and Characteristics of European Overhead Cranes

What is European overhead crane?


European overhead crane is a type of overhead crane, which is not a basic concept in professional terminology. It is a overhead crane developed by Chinese crane users based on the reliable, versatile and low-cost design and manufacturing technology of cranes (originating from Soviet model) and advanced scientific and technological development of European cranes, with more compact structure, lighter weight, energy-saving and low noise features according to our usage characteristics, meeting a clear market demand.


European overhead crane is manufactured and processed by advanced production technology based on European lightweight and modular design concept, making the whole crane structure compact, stable in operation, lightweight in self-weight, greatly reducing the construction time cost of crane plant and operating environment cost, and improving the overall quality and operational performance of the crane. European overhead crane will gradually become the mainstream of the development trend and market demand of cranes. EOTC crane is one of the representative products.


Characteristics of European overhead crane


  • Low in height and light in weight, it can lower the height and load of crane workshop.

  • It can enlarge the space for operation of mobile cranes.

  • The reducer of European overhead crane adopts hard-tooth surface reducer, which effectively improves the service life of the whole machine.

  • The reducer adopts hard-tooth surface three-in-one reducer control motor, with compact layout and stable operation.

  • Forged wheelset, high machining and assembly accuracy, long service life.

  • European overhead crane uses different steel plate rolls to improve the strength and service life of one drum.

  • A large number of processing equipment, overall processing, small structural deformation, high assembly accuracy.

  • The main beam connection can be assembled with high-strength bolts, with high assembly accuracy and convenient transportation and management.

  • Maintenance-free inspection cycle of overhead crane spare parts such as reducer, drum and coupling is realized for European overhead crane.

  • It adopts variable frequency speed regulation, with smooth operation, and all kinds of environmental protection devices are complete.


Characteristics of planetary gear of European overhead crane


  • NGW type planetary gear transmission of European overhead crane. High efficiency, small size, light weight, simple structure, convenient manufacturing, large power transmission range, small axial dimension, can be used under various working conditions, but the range of single-stage transmission ratio is small.

  • N-type low-backlash planetary gear transmission of European overhead crane. The transmission ratio range of European overhead crane is larger, with compact structure, small volume and weight, but the efficiency is lower than that of NGW type, and the radial force of internal gear after gear displacement is large, which increases the radial load of bearings, suitable for low-power or short-term work;

  • NN type planetary gear transmission of European overhead crane. The transmission ratio range of overhead crane is large, the efficiency is low, and it is suitable for short-term work. If the planet carrier is the driven component, the mechanism will be self-locked when the transmission ratio reaches a certain value;

  • NGWN type planetary gear transmission of European overhead crane. The transmission ratio range is large, the structure is compact, the volume is small, the efficiency is lower than that of NGW type, and the processability is poor, which is suitable for medium and small power or short-term work.
