Description

technical field

[0001] The invention relates to a fixed-column crane, in particular to a fixed-column full-slewing crane. It belongs to marine lifting and transportation machinery. Background technique

[0002] The existing fixed-column cranes generally include two types, that is, the column-type King Post Crane and the mast-type Mast Crane. The turntable and the top pulley device of the King Post Crane-type slewing crane are integrated into one body through solidification of the steel structure, and the boom is installed on the On the turntable, a rotary part is formed. The top pulley device can be at the center of revolution of the fixed column, or it can deviate from the center of revolution. The entire rotary part is sleeved on the fixed column from top to bottom, and the lower part of the turntable has no support. The top of the fixed column is supported by a bearing assembly, and the lower part of the fixed column has an annular track parallel to the center of rotat...
