FIELD: mechanical engineering; load-handling facilities. ^ SUBSTANCE: proposed tackle block 1 consists of fixed holder 2 and movable holder 3 connected by wire rope 4 passed in grooves of rollers 6 fitted on axles 7 and 8. Housings of holders 2 and 3 consists of two universal semihousings 10 arranged opposite to each other relative to diameters of rollers 6. Semihousing 10 contains central plate which forms lip 12 from side of outgoing wires of rope 4 with fitted on guide bushings 13, and from opposite side said plate is transformed into member of load jaw 15. Wings 20 formed at sides of plate 11 unite all parts of holders 2 and 3 into integral unit by means of axles 7 and 8 which are rigidly fitted in holes of wings 20. ^ EFFECT: enlarged functional capabilities of tackle block. ^ 4 dwg |
