摘要： Lifting device (D) comprising a frame (4) for fixing to the tractor chassis, said frame being fitted, on its lower part, with lower securing means (A), articulated about a transversal axis and extending towards the front, with its ends capable of being coupled to the two lower fastening points of a tool, and on its higher part, with median upper securing means (16). Lifting means (14) are provided between the frame (4) and lower securing means. The lower securing means (A) comprise, firstly, a lower primary structure (19), articulated at its rear part on a transversal axis (18) carried by the frame (4), and provided on the front with two longitudianl lateral extensions (21) in which a transversal bearing (26) is provided, and secondly, a forearm (29) associated with each longitudinal extension (21) and articulated about an axis (34) carried by said bearing. The forearms are independant; each (29), when in a work position, comes to rest by means of its rear part, under a stop integral with the structure (19), so as to block itself on lifting of the structure or on load raising. When the forearm (29) is free of its load, it can be folded upwards in relation to the frame (4), for a storage position. The forearm is provided, in a high position of the frame (19), with a stationary locking device to prevent both the structure and forearms form dropping, and to prevent the latter from rotating in relation to said structure.
