<p>Control device for trucks of the drive control type (7, 8) with a number of Hall-sensors (1(9 that are successively activated by a magnet (17) that is in turn mechanically activated, so that via a logic circuit a varied drive current is fed to the drive motor. The Hall-sensors (18) are arranged on a circuit card 19 that also include logic circuits. The control device is programmed to achieve a stepless transition between different sensors corresponding increase steps, at which the time for the change between the different increase steps corresponds to the time between the different sensor positions are passed, so that a rapid control movement result in a fast ramping while a slow gives a calmer ramping. <IMAGE></p> |
