Talking about the structural characteristics of the main beam of European crane
Why is there such a concept as a European-style crane? The purpose is to differentiate it from the so-called domestic, Soviet (Soviet) and traditional cranes in the past. European overhead cranes have light weight, compact structure and low energy consumption. They are installed on the bridge A trolley and lifting mechanism.
The trolley can rotate back and forth, and the trolley rotates to complete the transfer of materials and objects in the three-dimensional space. The main beam structure of the European crane: The main beam is designed with a square box-shaped Ankang H-shaped steel structure, which is similar to the traditional initial simple crane, and has a heavier weight. .
The main welds are all subjected to non-destructive testing; the steel plate material is domestic general steel (Q235B); the vertical winding is shot blasted according to my country's national standards and my country's traditional cranes, and all steel plates are shot blasted to reach Sa2.5 level standardization; carefully before welding Check and clean the steel plate, usually by automatic welding machine (MIG or semi-automatic welding).
Features of European crane end beams: The end beams are welded and formed by rectangular steel tubes or steel plates. The formed end beams are positioned and processed at a time on the CNC machine tool to reach the agreed deviation scale; each end beam is equipped with wheels with double rims, buffers and guards. Derailment protection device.
