PROBLEM TO BE SOLVED: To provide a slewing frame for a wheel crane allowing to prevent deformation, improve operability, and attain simplification and light weight. SOLUTION: In this slewing frame 20, a side stand 23 is provided with leg parts P3, P4 to receive force exerted on a boom foot pin supporting part 31 and a cylinder foot pin supporting part 32 on a base plate 21 right above a front and rear side of a slewing bearing 22 going across a plane containing the boom foot pin supporting part 31 and the cylinder foot pin supporting part 32, and deformation of the side stand 23 in a vertical direction can be thereby suppressed.
