Crane socket for a loading crane

Abstract

The invention relates to a crane socket for a loading crane, including a base part which has a bearing region for bearing the rotatable part of a loading crane, at least one support part which is used to additionally support the crane socket on a substructure, and a joint which connects the base part to the at least one support part. The joint is a torsionally flexible support, in which a first end of the support is connected to the base part, and a second end of the support is connected to the at least one support part.

Claims

1. A crane base for a loading crane comprising: a base part having a mounting region for mounting a rotating part of the loading crane; a support portion for supporting the crane base on a substructure; and a joint connecting the base part and the support portion together, the joint being a torsionally flexible carrier having an open cross-section with an I-profile, a first end of the carrier being directly attached to the base part and a second end of the carrier being directly attached to the support portion.

2. A loading crane comprising the crane base as set forth in claim 1.

3. A motor vehicle comprising a substructure, and the loading crane as set forth in claim 2 fixed to the substructure.

4. A motor vehicle comprising a substructure, and the crane base as set forth in claim 1 fixed to the substructure.

DETAILED DESCRIPTION OF THE INVENTION

(9) FIG. 3 shows an embodiment of a crane base 1 according to the invention. The base part 2 has a mounting region 21 for mounting the rotating part 7 of a loading crane 6 (see FIG. 5). The base part 2 and the at least one support portion 3 are connected by a joint in the form of a torsionally flexible carrier 5 (see FIG. 4f), in which a first end 51 of the carrier 5 is connected (directly attached) to the base part 2 and a second end 52 of the carrier 5 is connected (directly attached) to the at least one support portion 3. There is no rotary joint between the base part 2 and at least one support portion 3. The necessary rotatability of the base part 2 and at least one support portion 3 is afforded solely by the torsionally flexible carrier 5.

(10) The profile cross-section belonging to that carrier 5 is shown in FIG. 4d. FIG. 4e shows an alternative. Independently of the form of the profile cross-section (here, an I-profile), the open configuration of the carrier 5 is important as the torsional flexibility is afforded thereby.
