First Claim
1. An apparatus for reducing the axle load of a multiaxle movable crane, consisting essentially of:
- a truck;
a superstructure rotatably mounted on the truck;
a main jib releasably fastened to the superstructure and including a basic jib, at least one telescopic section, and a pair of rollers fastened to the basic jib, the basic jib having a sidewall and an end region;
a semitrailer having a front end, a back end with a loading area, a first ramp-shaped beam and a second ramp-shaped beam arranged in a longitudinal direction of the semitrailer in the loading area so as to be parallel to and at a distance from one another and to form a longitudinally extending ramp, each ramp-shaped beam having a top edge and a contoured runway disposed along the top edge, said rollers being configured to engage the contour of the runway and operable to transport the main jib from the superstructure directly to the semitrailer, the semitrailer further having a saddle, and a receiving part disposed on said saddle so as to be angularly movable and laterally displaceable so as to receive a roller head of the main jib for transporting the main jib from the truck to the semitrailer;
a pair of web plates angled in a transverse direction of the basic jib and fastened to the sidewall, the rollers being mounted to the web plates; and
additional rollers arranged in the end region on each side of the basic jib, said superstructure having rails arranged thereon, wherein said rollers and said rails form a guide for transport of the main jib.
