Ski jump approach approach device, approach finishing device of approach slope, approach slope adjustment method and home finishing method

摘要

By promoting the mechanization of the approach slide maintenance of the jump course by the manpower without the manpower without the maintenance of the jump course, the homogenous and high-precision approach of the bow despite the safety of the maintenance profession, speedy maintenance, And an object of the present invention is to provide a groove finishing apparatus of an approach slide surface and a groove finishing method of a slide surface that can perform main surface maintenance.;A pair of guide rails provided parallel to both sides of the approach slide surface of the ski jump base, a main body which travels along the rail and a cable laid along the rail, and a lower portion of the lower side of the lower side of the main body, A snow removing and pressurizing plate for snowing over the snow on both sides of the runway and at the same time the snow on the approach surface of the approaching runway is mounted on the upper end of the mountain of the main body of the maintenance machine and the pressurized and flattened And a rotary cutter for forming two approach grooves parallel to the description of the approach slide surface, and is an approach slide surface maintenance apparatus for maintaining this approach slide surface while vertically moving the main body of the main body by a cable.
