Abstract (en)
[origin: WO0020321A1] The invention concerns a mini-crane comprising a base (1), a mast (2) mounted above the base (1), a jib (3) in several sections (31, 37, 30) mutually articulated along vertical pivot axes (38, 36), and a counterweight (30) balancing the load (6). The distal section (30) of the jib (3) is articulated in vertical oscillation (141) about a horizontal oscillation axis (41), and stressed upwards by a compression spring (43) whereof the extension is limited by a stop. A winch (8) stresses the chain (7) linked to the load (6). The elastically stressed distal section (30) thus constitutes an elastic linkage with a threshold, which provides flexibility for supporting the load (6) and facilitates positioning for constructing a wall.
