摘要

u0432u044bu0433u0440u0435u0431u043du043eu0435 device consists of a working u0431u0430u0440u043eu0432u043eu0439 chain u043fu043eu0434u043fu0443u0442u043du043eu0439 beams, working and the speed of sending channels u0436u0435u043bu043eu0431u0430u043cu0438 and u043au043eu0440u043eu0431u0430u043cu0438, colin and ploughs.chain assembled by welding from the field (14, 19) and film (15, 16, 17, 21) elements. the role of the present moment (front) perform toughened ridges (28). focus (21) is presented.protection from the blast is dry 27 connecting link. u0442u043eu0440u0446u044b u0437u0430u0445u043eu0434u043du044bu0445 panels of all elements of the chain are however hard alloy plates, creative form.protective u0442u0432u0435u0440u0434u043eu0441u043fu043bu0430u0432u043du044bu0435 plates fitted to the contour of u043fu043eu0434u043fu0443u0442u043du043eu0439 beams, one working channel and ploughs.the technical result of the invention is achieved through a reduction in u0442u0440u0443u0449u0438u0445u0441u044f surfaces at 15% - 20%.
