ABSTRACT:
An adjustable seesaw ski-track includes a stationary central part and separate wing sections pivotally connected to opposite sides of the central part, each wing section including a horizontal platform section and a plurality of pivotally connected wing sections extending between the platform and the central part. A coupling rod connects the two wing sections together, and a hydraulic cylinder assembly is connected to one of the wing sections so as to raise and lower its platform section relative to the central part, thus pivoting the wing section upwardly and downwardly relative to the central part, the coupling rod causing the other wing section to respectively pivot downwardly and upwardly relative to the central part.
