摘要

The device has a base frame (3), and rail-bounded guideways (S1, S2, W1, W2) that are provided for both winter and summer operations. A structural unit (2) has surfaces that are arranged in parallel with respect to the base frame in a height adjustable manner. The surfaces are connected with each other by a side wall. The side wall stays in effective connection with a supporting unit (4) that is arranged on the base frame, where the side wall is arranged at a certain distance from the base frame. A sliding unit (8) and a guideway limiting device (9) are fastened to the structural unit. Independent claims are also included for the following: (1) an arrangement/structural group of two devices that are installed along a ski device (2) a method for installing a structural group (3) a method for connecting an arrangement with a base frame.
