Claims

[Scope of utility model registration request]

The machine moves along a spinning machine table that is equipped with guide rollers that extend along the longitudinal direction of the spinning machine table and roll while engaging with guide rails, and wheels for running on the floor that can be moved up and down by a lifting device. The machine is equipped with a posture control device that detects the inclination of the work equipment due to irregularities on the floor surface and moves the floor running wheels up and down to control the inclination so that it does not interfere with the work. In a work machine with a posture control device, the floor traveling wheels are supported on a support arm constituting the lifting device so as to extend in a horizontal direction perpendicular to the direction of movement of the work machine. A posture control device is provided between the support arm and the floor running wheel, the support arm being supported so as to be relatively movable in the axial direction, and a biasing means for locating the floor running wheel at a reference position of the support shaft. Wheels for running on the floor of work equipment.
