ABSTRACT:
The invention relates to a displacement device, particularly for construction machines, having a guide, a carriage, which is displaceably mounted along the guide, and an operating cylinder for displacing the carriage. According to the invention, for increasing the buckling resistance, at least one support element is provided, being displaceably mounted both on the piston rod and on the guide or the carriage and that for preventing lateral buckling of the piston rod, on extending the said piston rod the support element is displaceable up to a predetermined support position on said piston rod.
