Abstract (en)

[origin: WO03076131A1] The present invention relates to an arrangement in a mobile machine (1) for grinding floor surfaces, comprising a housing (1a), which is supported partly by two wheels (4, 5) and partly by a number of rotatably supported grinding disks (1c1, 1c2, 1c3, 1c4), which are distributed over planet disk (1d) rotatably supported at the bottom of the housing (1a) and are operatively connected to a drive motor (1b), the planet disk (1d) being designed to be driven by the drive motor (1b). The grinding disks are four in number and the arrangement comprises a drive motor (4a, 5a) mechanically connected to each wheel (4, 5) and a control unit (6) influencing the direction of rotation and the rotational speed of the drive motors (4a, 5a), the control unit being operatively connected via a radio communications unit to an operating device (7). The latter is designed for manual actuation by an operator (8) for remote control of the grinding machine (1).
