欧式起重机与传统起重机金属结构差别
1.主梁结构的差异
传统起重机a主梁属于多种中轨，b有多快小隔板，c传统起重机上盖板S1≈12-20，d用钢轨压板工字型钢轨
2.端梁结构的差异
3.走台的差异
副走台
Share the difference with the traditional European crane metal structure of crane
The difference between the 1 main girder structure
The traditional crane girder a belongs to a variety of rail B, how fast the small partition on the cover of S1 C traditional crane was 12-20 d with the I-shaped rail rail plate
European crane: A for partial rail, B small partition, C cover S1 = 8-12, D steel plate, Fang Gang rail welding
The difference between the 2 end beam structure
The traditional crane: a welding box beam, B broke in the middle position is connected by bolts, C and main street, D angle box supporting wheel for vehicle
European crane: a square beam profiles, B broke in the middle is fixed C and beam lap bolt, D for boring wheels
The traditional crane: due to the end girder so one beam weight, complex structure, easy transportation, installation accuracy and low installation to wheel
European crane: simple structure, separated from the main girder and end girder with convenient transportation, convenient installation, high precision wheel mounting
The difference between the 3.
The traditional crane: a installation and carrying a taxi driving mechanism of the impact, B platform support and a side profile specification is large and heavy, C platform width, d need to install side platform
European crane: A does not support the S8 B installation plate, bending the platen become round, C platform width is small, no need to install the D difference:
Vice.
The traditional crane: complex structure, high quality materials, support, installation of crane operation impact, platform width
European crane: no installation run the cart driver, support is not much, go to Taiwan narrow and light weight.
