FIELD: transport. ^ SUBSTANCE: invention relates to machine building and can be used as hoisting device in various fields of national economy, in particular for reloading large-dimensioned cargoes and mounting long-length structures. Self-propelled double-jib crane includes two rotating platforms or two rotating pillars, one pillar for each jib. Telescopic jibs are used. Support platform is mounted on automotive or crawler self-propelled chassis. ^ EFFECT: enhancement of crane technological capabilities in terms of large-dimensioned and long-length cargoes with providing required values of not only linear but also angular coordinates of cargo, increased mobility, manoeuvrability and independence of crane movement, lower labour consumption during mounting and dismantling of crane for moving to another site. ^ 2 cl, 4 dwg |
