Crane girder load turning device
The utility model relates to an overturning positioning device for a main beam of a crane, which comprises at least two overturning frames arranged in the front and the rear;
The turning frame is composed of a base, a circular turning body and a roller, the rollers are rotatably installed on the left and right ends of the base, the circular turning body is seated on the base and its arc end face is in contact with the roller, and the circular turning body has The central shaft hole matched with the main beam of the crane, the central shaft hole is extended in the direction of the central axis with a number of pressing blocks for pressing the end face of the main beam of the crane, and the two outer sides of the base corresponding to the circular inverting body are respectively installed with a controllable circular inverting body locking mechanism. The beneficial effects are as follows: the structure is simple and reasonable, the turnover cost is reduced, the work efficiency is improved, and the welding quality is guaranteed.
