Abstract
Provided is a mobile workbench constructed so as to determine that an accident of some kind has occurred and to stop if the speed of the mobile workbench suddenly changes. A mobile workbench (A) travels on a material (Ca) to be processed and performs predetermined processing (welding) by using a processing tool (welding torch (B)) mounted thereon. The mobile workbench (A) comprises: a workbench main body (); a plurality of wheels () which are provided on the workbench main body (); a drive motor () which drives the wheels (); an acceleration sensor () which detects the acceleration acting on the workbench; and a control unit () which is constructed so as to determine that an abnormality has occurred and to stop the drive motor () if a sudden change in speed is detected by the acceleration sensor ().
