Abstract:
A sledge or equivalent transporting base, consisting of a frame (1) and of thereinunder mounted travelling members such as runners (2), with reference to which the frame is movable in the direction longitudinal to the sledge. To the runner (2) has been pivotally attached an arc-shaped rolling member (3) with the center-point of its radius at the pivotal point and which is free to roll along an opposed counterface (5) on the frame (1). With the aid of the invention, sledge runners which have frozen fast to snow or ice can be easily freed by first backing up so that the load rolls into its rear position, whereafter the sledge is started, whereby with the aid of the load's mass the runners are jerked free from frozen-on snow and ice.
