Figure 3 is the same (an explanatory diagram showing the non-uniformity of the amount of deformation of the lock ring). Figure 4 is a sectional view of the main part of the fixing device incorporated in the present invention. Figure 5 is the same (showing the released state). Fig. 6 similarly shows the fixed state. Fig. 7 shows an example of the coupling structure between the retainer and the ball race in a known fixing device.

Claims

[Scope of utility model registration request]

In a truck crane having an upper revolving body 2 rotatably mounted on an undercarriage 1, the upper revolving body 2 and the undercarriage 1 are connected to each other by a telescoping fitting part, and the fitting part has mutually connected parts. It has an annular groove (A and B) aligned with the groove, into which two or more divided retaining rings 6 are fitted, and each retaining ring is operatively connected to a rotating body 14 driven at the center. The retaining ring 6 is rotated by the rotation of the rotating body 14.
A partial fixing device for a truck crane, characterized in that an upper rotating body 2 and a lower traveling body 1 are fixed and released by expanding and contracting.
