Abstract: The load-lifting crane has a jib mounted on its framework, the end of the jib having an extension connectable thereto, the ends of the jib and of the extension carrying blocks over which a run of the rope coming from the winch is adapted to be alternatively guided to form a tackle arrangement supporting a load-engaging device. The ends, respectively, of the jib and of the extension have each mounted thereon an additional block adapted to have a run of the rope coming from the tackle, which is the double one, running over it, the end of the last-mentioned run being secured to the framework. The block over which runs the run of the rope, coming from the winch, and the respective additional block are offset relative to each other laterally of the jib by an extent not short of the diameter of the rope.
