Abstract
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.
Claims9
A crane, comprising:
- a luffing jib configured to telescope at both ends, and having a base boom, the luffing jib being swingable up and down as well as raisable and lowerable with the base boom;
- a swivel bearing respectively provided at each end of the base boom, each swivel bearing being raisable and lowerable, the luffing jib being swivelable about vertical axes in a region of the swivel bearings;
- and
- two multiple-axle traveling mechanisms, each swivel bearing being supported at one of the traveling mechanisms so as to be displaceable traverse to a longitudinal axis of the crane and so that the two traveling mechanisms are connected with one another by the base boom of the luffing jib.
