Marksa, Novosibirsk, 630073, Russian Federation 2 Chinakal Institute of Mining of the Siberian Branch of the RAS, 54 Krasny ave., Novosibirsk, 630091, Russian Federation Abstract Pneumatic machines of vibropercussion action are more widely used for pipelaying, especially, in the conditions of dense city building. It is experimentally proved that increase of pipelaying speeds requires additional power influence in the horizontal direction. Realization of such influence by means of the winch with a pneumatic drive working from the mobile compressor is offered. Requirements to the sizes, weight and transportation conditions of the developed winch are formulated. The advantages of the developed equipment are: simplicity of service, fire and explosion safety, reliability of work in the wide range of temperatures, in the conditions of dusty and damp environment, high operation speed.
