Abstract
A wheeled work machine in which the center of gravity of a machine body is positioned low and the stability of the machine in a working position is secured without regard to the movement of the center of gravity caused by the rotation of a rotation table during work. An operation body () integrally rocking with a front axle case () is provided at the center in the left-right direction of the front axle case (), and a rocking lock mechanism () for limiting the rocking of the operation body () is provided at a machine body frame (). The rocking lock mechanism () has a lock cylinder () in which a piston rod () is horizontally fixed to the machine frame () and a switchover valve () for switching two oil chambers (A,B) of the lock cylinder () between a communicated state and a closed state. A cylinder tube () of the lock cylinder () is operably connected to the operation body ().
