FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to facilities for load lifting, particularly to tower-type ram engine. Ram engine consists of supporting framework and under-sheave platform, which is implemented in the form of framework, including top and bottom planes, connected by strut beams. In specified planes by axis of descending branches of lifting cables there are built in bearings with located in it bushes. To bushes by means of gib arms there are connected angle pulleys with passed from it lifting cables by axis of bearings. Additionally in bottom bush it is implemented reach-through hole, through which it is passed hoisting cable. ^ EFFECT: solution is directed to increasing of manufacturing capabilities of ram engines and hoisting plants. ^ 4 dwg |
