Abstract

A method for the positionally correct placement of an operating equipment including a scoop tiltably disposed on a descending lift frame of a mobile machine including a wheeled loader. An automatic positioning device is actuated thereby activating a first magnetic valve utilizing a logical switching device cooperating with the automatic positioning device for switching a tilting piston of a control slide operatively connected to a tilting cylinder and to the lift frame into a position in which the control slide releases an oil flow to the tilting cylinder. The oil flow is delivered utilizing a controlled pump. A plurality of measurements is performed of a traveled distance of a piston rod of the tilting cylinder at predeterminable places during a continued extension of the piston rod thereby obtaining distance measurement values. A first signal is triggered in response to a first one of the distance measurement values for activating a second magnetic valve utilizing the logical switching device for moving the tilting piston into a position where a predeterminable reduced oil flow is released to the tilting cylinder. During a slowed-down, extending movement of the piston rod, a second signal is triggered in response to a second one of the measurement values for deactivating the logical switching device with respect to the first magnetic valve and the second magnetic valve and for interrupting an oil flow to the tilting cylinder.
