Abstract

The invention relates to a parallel guide device for an attachment, e.g. a front loader attachment, which is pivotally mounted on a link pivotally mounted on a vehicle. The device comprises an attachment lifting cylinder 12, a double-acting attachment tilting cylinder 30, a master cylinder 17 sensing the angle of inclination of the attachment, an hydraulic servovalve 50, 60 in respect of each of the tilting and lifting cylinders 30, 12 and a control valve 40 having two positions in the one of which shown the cylinder spaces 33, 34 of the tilting cylinder 30 are connected to the lifting cylinder 12 and master cylinder 17 respectively and in the other of which the lifting cylinder 12 is connected to the master cylinder 17, and wherein the master cylinder is formed as a part of the lifting cylinder 12. <IMAGE>
