Abstract

The invention provides a combined arm joint of a crane, the crane and a mounting method of the crane. The combined arm joint comprises an arm joint body (110) and a connecting part (170) arranged on the arm joint body (110), wherein the connecting part (170) is located between a first end and a second end of the arm joint body (110) opposite to each other and used for being connected with the upper end of a rotary assembly (300) of the crane; and in the arm joint body (110), a rotary tower body section (112) is formed in the connecting part (170), a balanced arm joint section (111) as a first arm joint of a balanced arm of the crane is formed between the rotary tower body section (112) and the first end, and a lift arm section (113) as a first arm joint of a lift arm of the crane is formed between the rotary tower body section (112) and the second end. According to the combined arm joint of the crane, the quantity of parts at the upper part of the tower crane is reduced and the design, manufacturing and mounting operations are simplified.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a combined jib section of a crane, a crane and a method for installing the crane. Background technique [0002] In the prior art, the first section of the balance jib section, the slewing tower body and the first section of the boom section of the tower crane are arranged separately. The installation process of this tower crane is as follows: figure 1 shown, where figure 1 .1~1.6 represent respectively: [0003] 1.1. Install tower body and slewing assembly 1; [0004] 1.2. Install the slewing tower body 2 on the slewing assembly 1; [0005] 1.3. Install the first balance jib section 3 on the rear side of the slewing tower body 2; [0006] 1.4. Install the second section of the balance arm section 4 and part of the counterweight (such as a counterweight); [0007] 1.5. Install the boom 5 and the remaining balance weight on the front side of the slewing tower body 2; [000...
