AN APPARATUS FOR FORMING A TERRAIN FEATURE |
摘要 |
<p>The present invention relates to an apparatus for forming a terrain feature such as a snow half pipe used by snowboarders or skiers. Known half-pipe cutters are inaccurate and limited in height which limits the quality of the formed snow course. The apparatus comprises a frame which comprises an attachment for a self-actuated vehicle and a tool member adapted to the cross-sectional shape of the terrain feature; at least one primary forming surface, such as a belt, running over a working surface of the tool member to form the terrain feature; at least one secondary forming surface, in the form of a heated bar and finishing mats, to contact the formed terrain feature and provide a finish to its surface; and a guidance device, such as a laser guided device, to determine the position of the tool member with respect to the terrain surface.</p> |
