Crane, in particular railbound mobile crane

摘要

A crane, in particular railbound mobile crane, with a luffing jib telescoping at both sides which can be swung up and down as well as raised and lowered with its base boom. The boom is supported in its end regions at the vehicle on a swivel bearing which can be raised and lowered. The luffing jib is swivelable about vertical axes in the region of the swivel bearings. For this purpose, every swivel bearing is supported at one of two separate multiple-axle traveling mechanisms so as to be displaceable traverse to the longitudinal axis of the mobile crane. The two traveling mechanisms are coupled with one another via the base boom of the luffing jib, which base boom is connected with the swivel bearings.
