European cranes are different from previous domestic, Soviet and traditional cranes. Mainly include: bridge cranes, gantry cranes, cantilever cranes, explosion-proof cranes, etc. Although the design of the steel structure is basically the same as that of ordinary cranes, European cranes have stable performance, compact structure, reduced self-weight, reduced height, energy saving and consumption reduction, and high cost performance compared with ordinary cranes.
Compared with ordinary single-girder cranes, European-style single-girder cranes are different as follows:
1. Compared with ordinary cranes in terms of performance, European-style cranes have more reliable performance and lower failure rate. The operating mechanism reducer of European-style cranes adopts a three-in-one reduction motor with hard tooth surface, which is compact in layout and stable in operation. Using forged wheel set, machined boring assembly, high assembly precision and long service life. The steel plate is used to roll the reel, which improves the strength and service life of the reel.
2. In terms of self-weight, ordinary cranes are traditional cranes, also known as Soviet-style cranes, which can be traced back to the former Soviet Union. At that time, foreign countries blocked Chinese technology and only learned crane manufacturing experience from the Soviet Union. However, due to the coldness there, all the main beams The structure and electrical components are designed to be designed in extremely cold conditions, so it is very bulky, backward in technology, easy to break and other defects. An ordinary crane is about 30% heavier than a European crane.
3. In terms of energy saving, ordinary cranes are bulky and consume a lot of energy, while European-style cranes have a more compact structure and lower height through optimized design. Under the same plant conditions, the installation of European-style cranes can increase the lifting height. If a new factory building is built, the European-style crane can be used to reduce the height of the factory building; if the truck is retrofitted, the European-style crane can be used to reduce the retrofit cost. Lightweight European-style components, flexible technology application, and optimized design of the main beam. The application of new energy-saving technologies such as European direct drive and variable frequency drive has greatly improved work efficiency.
