A collapsible hoisting device for use in the construction of large metal containers and to a removable accessory applicable thereto. It facilitates construction procedures by reducing project times and costs. The collapsible device includes a column (2) along which respective upper bodies (6) and lower bodies (7) that have been inserted into said column (2) move. The bodies (6, 7) are linked by an extendable means (8). The upper bodies (6) and lower bodies (7) have a corresponding mechanism to lock or attach (9) to the column (2), The column (2) is mounted so that it pivots with respect to a base (1) and the upper body (6) has a housing (609) suitable for the insertion of a removable, fingernail-shaped accessory (12).
A folding lifting device to be used in the construction of large metal tanks, comprising a column (2) on which respective upper (6) and lower (7) bodies are so they can move along the column (2), said upper and lower bodies (6 and 7) are linked by each other by means of a tensile element (8), and said upper (6) and lower (7) bodies having a means for locking or fixing (9) to said column (2);
A removable fitting applicable to a folding lifting device, comprising at least two equal and opposite linkable parts (14), each one formed by a whole set that includes two rectangular horizontal plates (904) with a semicircular perforation in a middle of one of its longer sides of the two rectangular horizontal plates (904), separated by four metal bars having a square section (905), so as to leave two spaces or boxes (906) between both plates for insertion of a respective horizontal plate with a perforation spaced from ends in each one of the spaces or boxes (906), said horizontal plates in turn inserted in each box frame (609) of the fitting supporting system (10), and the whole set being firmly welded to a rectangular and horizontal plate (901) with a semicircular perforation in the middle of one of longer sides of the rectangular and horizontal plate (901), but of a larger size than each of the rectangular horizontal plates, two supports (902) welded at shorter sides of the rectangular and horizontal plate (901), each one with a pass-through perforation (903) enabling passage of a bolt to fix said at least two equal and opposite linkable parts (14) to each other;
