1. Apparatus for handling large elongate articles, such as bolts (36), allowing the bolt to be moved vertically and pivoted into a horizontal position, and vice versa, characterised in that it incorporates a pivoting arm (18) capable of tilting about a fixed axle (19), located in the vicinity of the lower end of the arm, and serving for guiding a movable carriage (24) capable of moving along the said arm and equipped with supporting means (34) for the lower portion of the bolt (36), at least one cable (17), one end of which is fastened to the movable carriage (24) and the other end of which interacts with a fixed winch (11), the capable passing via at least one fixed member and also over a loose pulley (37) mounted on the arm (18) above the said fixed axle (19), and means (44) of receiving the bolt (36), these means being attachable removably to the pivoting arm (18), the weight of the movable carriage (24) being such that the force on the loose pulley (37) remains sufficient to bring the arm (18) into a vertical position and maintain it there. |
