PROBLEM TO BE SOLVED: To provide a compact snowplow that removes snow on a roof by operating a remote controller.SOLUTION: A rail is installed on a ridge horizontally. A compact two-wheeled trailer is mounted on it, and contains winch connected to a rear part of a snowplow on the roof with wire. When snow falls, the snowplow is started to remove snow. The width of a snowplow blade is as long as a shovel, about 30-60 centimeters. The wire reaches the end of the roof, and it is taken up to ridge as soon as snow removal is completed. The trailer moves to the left or right horizontally only by the width of the shovel. The snowplow performs next snow removal operation. In the case of a hipped roof, the height of the rail is properly reduced and the rail is installed horizontally on four sides with four corners rounded, thereby enabling one snowplow to remove most of the snow. The snow can be removed along the hip by operating a steering wheel. Safety can be enhanced by an electric vehicle that uses no gasoline. |
