Abstract

The invention relates to the field of construction machinery, and discloses a slewing assembly and its upper support, a slewing assembly assembly and a tower crane, wherein the upper support (10) comprises a support main body and is arranged on the support A first connecting structure on one side of the main body for connecting the boom (50) and a second connecting structure on the other side of the support body for connecting the balancing arm (60). The application can use the upper support to connect the bottom end of the root of the boom and the balance arm, so that the total height of the slewing assembly and the tower head is basically the height of the boom and the slewing bearing of the slewing assembly, the height of the lower support The sum of the heights reduces the height of the upper support, thereby meeting the height limit requirements of transportation, so that the slewing assembly and the tower head can be assembled and transported together.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a slewing assembly and its upper support, a slewing assembly assembly and a tower crane. Background technique [0002] In the prior art, the top and bottom ends of the roots of the boom and balance arm of the tower crane are connected to the tower head, the tower head is connected to the upper support of the slewing assembly, and the lower support of the slewing assembly is connected to the tower. body. Therefore, the height of the part above the slewing assembly is the height of the slewing assembly (the sum of the heights of the upper support, the slewing bearing and the lower support) and the height of the tower head (the height of the tower head is basically equivalent to the boom and the height of the balance arm). During the transition, the tower head and the slewing assembly need to be assembled and transported together, which may exceed the transportation height li...
