FIELD: transport.
SUBSTANCE: proposed plant comprises box-like scraper connected by leading and trailing cables with two-drum scraper winch, trailing cable resting on end and deflecting pulleys, and unloading ramp. Reverse branch of training pull cable after running around end deflecting pulley arranged in vertical plane is directed along scraper plant axis, cable being located thereunder between two horizontal deflecting pulleys. The latter cover the cable on both sides to displace it at therein interaction. Note here that both pulleys are secured at U-like frame arranged at scraper top parts. Horizontal rollers are arranged at front edges of scraper front and rear side to allow loose cable to rest thereon.
EFFECT: lower wear, hence, longer life, lower electric power input, higher safety.
