LOAD-LIFTING APPARATUS Russian patent published in 2005 - IPC

FIELD: agricultural engineering, in particular, may be used in load handling equipment for compressed fodder bales.

SUBSTANCE: load-lifting apparatus has bar with hanger and brackets for attachment of lower grip. Bar carries guiding bars for attachment of upper grip and brackets for attachment of hydraulic cylinder for lower grip drive. Lower grip has two poles and connecting member with six arcuate fingers and brackets for attachment of stem of hydraulic cylinder for drive. Upper grip is formed as orienting pressure frame composed of two vertical columns with through regulating openings and longitudinal and transverse connecting members. Vertical poles of upper grip are fixed on bar by means of guiding brackets for displacement and fixation therein by means of fingers. Arcuate fingers are extending along arc of circle with center lying on axis of rotation of lower grip to minimize damage to compressed mass and binding material.

EFFECT: simplified construction, enhanced reliability in operation and reduced damage to compressed mass of bale and to binding material.
