Abstract

The mechanism is partic. for a crane on a slewing base, having a jib derricking rope reeved round pulleys and onto a winch on the base. There is a rigid vertical support (10) fixed to the base platform and accommodating a telescopic arm (11), and between and winch (18) and the jib the rope (17) is reeved round a pair of pulley blocks (15, 19). One of the blocks (15) is attached to the free upper end of the arm, which is also equipped with lifting tackle (23, 24), by which the ballast forming the tailweight is hoisted into place. There can be a detachable locking device (13) at the upper end of the support, engaging with the lower end of the arm when extended, so that the latter can pivot on the support.
