Abstract

Device for erecting and lowering a derricking support (5) of a crane equipped with a subconstruction, a superstructure, a counterweight and a primary jib (2) provided on its head (6) with a hinged auxiliary derricking jib (3) connects the free end of the derricking support hinged on the head of the primary jib to the head region of the auxiliary jib via a fixed brace and to the superstructure, primary jib or counterweight via a fixed or length-adjustable brace. An auxiliary support (12) erected in the region of the jib forms a lever arm required for erecting the derricking support. Preferred Features: The auxiliary support is arranged on the derricking support so that it can be erected and lowered and its free end is connected to the derricking support and to a cable (17) via a fixed brace (14).
