Description

  The present invention relates to an automatic snow lowering machine that can efficiently lower snow on a roof with small power.

  During the winter, many accidents related to snow removal occur. The cause of the accident is that the worker falls during the snow removal work. Various snow removal machines have been invented to prevent accidents.

  Some conventional snow lowering machines use heat and water. By installing the heat generating device on the inner surface of the roof or using water or warm water, it becomes difficult for snow to accumulate on the roof, and it is not necessary to carry out snow frequently.

  Besides using heat and water, there are also automatic snow removal machines using pulleys and belt conveyors. By installing pulley rails and belt conveyors on the roof surface, it is possible to perform mechanical snow removal.

  Depending on the area and snow conditions, various sizes of automatic snow removal machines can be installed. The advantage is that snow can be removed with greater power than a snow remover that uses heat or water.

As described in Patent Document 1, an invention of a snow removal device for a roof that can mechanically efficiently remove snow with a small driving force with a simple device without using a heat source is also disclosed.
