FIELD: mechanical engineering; load-handling facilities. ^ SUBSTANCE: invention is designed for lifting and lowering of loads. Proposed load-gripping device consists of frame carrying electric motor and reduction gears to each of which two drive drums are connected. Textile tapes passed through holes in frame are wound on drums and they provide more tight holding of load. Pressure device in form of elastic pad is arranged in lower part of frame making it possible to press load and move it at high speed without swinging. ^ EFFECT: provision of quick lifting or lowering load in mine, load handling operations and mounting operations in difficult-to-get-at places, without assistance of slinger man and at minimum swinging. ^ 3 dwg |
