Abstract
A slewing frame of a work machine and a method of assembling a slewing frame of a work machine where the slewing frame is separable into at least two front and rear members, and an operation of connecting these two members can be easily performed. A slewing frame is separable into a front frame and a rear frame. When a pin fitting portion of a rear frame is fitted on a positioning pin of a front frame, and the rear frame is rotated downward, at a position where a front pin hole and a rear pin hole are aligned with each other, a contact portion of the rear connecting portion is brought into contact with a rotation preventing portion. As a result, a connecting pin can be easily inserted into the front pin hole and the rear pin hole.
