Claims

[Scope of utility model registration request]

This is a vehicle body rotation trolley for a wheel crane that is installed below the wheels that are both steering wheels and drive wheels, and rotates the vehicle body around the center of the vehicle body or the center of one axle. A rotational force transmission roller that is rotationally driven by rotation, and support rollers that support wheels on both front and rear sides of this rotational force transmission roller are provided parallel to the axis of the wheel, and a pair of front and rear rollers are provided at the bottom of the bogie frame. A drive shaft is provided so as to be inclined with respect to the axis of the rotational force transmission roller in a plan view, and left and right grounding wheels are respectively provided on both drive shafts, and a connection between both drive wheels and the rotational force transmission roller is provided. A gear transmission mechanism is provided between the rollers to transmit the rotational force of the roller to both drive shafts, and the inclination angle of the drive shafts with respect to the rotational force transmission roller is set to the center of the wheel in plan view in the maximum steering state of the wheel. A dolly for rotating a vehicle body of a wheel crane, characterized in that it is set at an angle formed by a line perpendicular to a straight line connecting the center of rotation of the vehicle body and a path of the wheels.
