Abstract

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.

Description

technical field [0001] The invention relates to the technical field of slewing device structure, in particular to a slewing device and a truck-mounted crane. Background technique [0002] Truck-mounted crane refers to a multi-action hoisting machine that is installed on the chassis of a car and can vertically lift and horizontally carry heavy objects within a certain range. During the lifting operation, the crane needs to rotate continuously within a certain range in order to place the heavy objects to the predetermined position. Traditionally, the slewing bearing is used to realize the rotating operation of the crane, but there are problems such as difficult installation and poor stability. Contents of the invention [0003] The object of the present invention is to provide a slewing device and a truck-mounted crane to solve the technical problems of difficult installation and poor stability of the slewing device in the prior art. [0004] In order to achieve the above ...
