Arrangement in a mobile machine for grinding floor surfaces

Abstract

The present invention relates to an arrangement in a mobile machine ( 1 ) for grinding floor surfaces, comprising a housing ( 1 a ), which is supported partly by two wheels ( 4, 5 ) and partly by a number of rotatably supported grinding disks ( 1 c 1, 1 c 2, 1 c 3, 1 c 4 ), which are distributed over planet disk ( 1 d ) rotatably supported at the bottom of the housing ( 1 a ) and are operatively connected to a drive motor ( 1 b ), the planet disk ( 1 d ) being designed to be driven by the drive motor ( 1 b ). The grinding disks are four in number and the arrangement comprises a drive motor ( 4 a, 5 a ) 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 ( 4 a, 5 a ), 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 ).

1 . Arrangement in a mobile machine for grinding floor surfaces, comprising: 
 a housing, supported partly by two wheels and partly by at least four rotatably supported grinding disks, the grinding disks being distributed over a planet disk rotatably supported at the bottom of the housing and operatively connected to a motor, and the planet disk being driveable by the motor;    drive motors, one mechanically connected to each wheel; and    a control unit influencing the direction of rotation and the rotational speed of the drive motors, the control unit being operatively connected via a radio communications unit to an operating device, designed for manual actuation for remote control of the machine.
