Zusammenfassung: | The invention (roof snow plane) relates to a method/a device, by means of which the snow on the roof can be cleared either from the ground - and then it is not necessary to go up on the roof (this applies in the case of buildings up to 4 m high - or from the roof ridge (this applies to buildings over 4 m high). Then, one is not exposed to the risk of a fall or accident. The roof snow plane consists essentially of an aluminium plate for lightness, and this is coated with simple glass fibre lamination in order to reinforce the structure and to protect roof constructions. By means of positioning the shaft fastening C of the pull/push arm B of the roof snow plane in a front-heavy manner in the longitudinal direction of the plate A in a ratio of 3:4 D, and in the centre of the plate A in the lateral direction, the object of versatile working and speed is achieved, the turning radius of 175° G of the plate A being in the direction of the arm B. The front edge of the plate A is bent 30° downwards E in |
