Claims

[Scope of utility model registration request]

The carrier frame of the lower traveling body is equipped with an upper revolving body equipped with an operator's cab that is used both during crane work and when traveling.The revolving frame of this upper revolving body is provided with boom foot attachment parts on both left and right sides, and the boom foot is installed on both sides. In the wheel crane, the boom hoisting cylinder is attached between the boom foot attachment sections on both sides by a boom foot pin, and the cylinder point of the boom hoisting cylinder for raising and lowering the boom is attached to the boom, and the cylinder foot is attached to the swing frame, respectively. is comprised of a bracket having a notch through which the boom foot pin can be attached and detached in the radial direction of the pin, and a holding fitting that is removably attached to the bracket so as to press the boom foot pin into the notch, A boom support device is provided at the front of the carrier frame so as to be movable between an upright position where the boom can be supported in a substantially horizontal position and a retracted position along the carrier frame, and a boom support device that supports the boom hoisting cylinder. A wheel characterized in that a hoisting cylinder support device capable of supporting the cylinder point so as to be movable up and down using the cylinder foot as a fulcrum in a state where the cylinder point is removed from the boom is provided at a position below the boom hoisting cylinder in the carrier frame. crane.
