The invention provides a gyration device and a lorry-mounted crane. The gyration device comprises a gear shaft, a base and a gyration stand column, wherein the base and the gear shaft are of an integral casting structure; the gyration stand column is welded to the base; and the gear shaft is used for driving the gyration stand column to rotate. In the gyration device, the gear shaft and the base are an integral-forming integral casting, a welding working procedure between the gear shaft and the base is avoided, processing is convenient, and stability is good when the integral casting drives the gyration stand column to rotate.
本发明提供了一种回转装置及随车起重机,回转装置包括齿轮轴;底座,与齿轮轴为一体式铸件结构;以及回转立柱,焊接于底座上,齿轮轴用以带动回转立柱转动。该回转装置中,齿轮轴与底座为一体成型的整体式铸件,避免了齿轮轴与底座之间的焊接工序,加工简便,且整体式铸件带动回转立柱一起转动时平稳性好。
