ABSTRACT:
In a mobile device for preparing the surfaces of ice-rinks with an essentially rectangular rink, an ice-scraping device for the mechanical smoothing of the ice surface and a distributing device for the even application of a film of water on the ice surface are mounted on a framework which extends parallel to a first rink edge across the whole rink and is slidingly guided at its axial ends along the two rink edges running at right angles to the first rink edge. The framework is mounted in height-adjustable manner on supports which roll on rails outside the rink. A barrier section of a barrier enclosing the rink, which is erected at right angles to the direction of movement, can be displaced in the direction of movement so that ice scraped off by the ice-scraping device can be pushed into a trench outside the rink.
