  • Patent number: 11427446
    Abstract: A vehicle crane having a telescoping jib, comprising a basic box with linearly displaceable inner boxes and a lifting cable with a load picking-up device. A fastening region is arranged on the basic box or on a head end of one of the inner boxes, and a bracing apparatus is securable to the fastening region by a connecting end. To simplify rigging/de-rigging of the vehicle crane in relation to the bracing apparatus, the fastening region is formed for mounting the bracing apparatus on the basic box or on one of the inner boxes such that a bracing apparatus that is freely suspended on the lifting cable is coupled to the fastening region with the connecting end being brought close to the fastening region by movements of the vehicle crane, retraction and extension of the inner boxes, raising and lowering of the load picking-up device, and/or luffing of the telescoping jib.

  • Publication number: 20210323798
    Abstract: An induction sensor assembly for a securing and locking unit of a telescoping jib having at least one signal transmitter configured for generating an electromagnetic stray field oriented towards its active switching surface, and at least one switching element provided for contactless cooperation with the signal transmitter. The signal transmitter and switching element are displaceable relative to each other in relation to an adjusting direction extending in parallel with a main plane. To provide a simple and cost-effective installation of the induction sensor assembly despite having high detection security, the active switching surface of the signal transmitter and the main plane are inclined with respect to each other. As such, the electromagnetic stray field of the signal transmitter is also advantageously inclined whereby a possible displacement between the signal transmitter and switching element cannot exert an influence on the precision of the position detection in relation to the adjusting direction.

  • Patent number: 10781851
    Abstract: A pivot bearing assembly includes a pivot pin and at least one bearing block, in which a bearing bush having a bearing bore is accommodated. The pivot pin is slidingly supported in the bearing bore. In order to create an improved pivot bearing assembly, the bearing bush has a rounded outer surface, which is inserted into a negatively rounded inner surface in order to orient the bearing bush.

  • Patent number: 6685039
    Abstract: An outrigger assembly for support of a mobile crane or excavator upon the ground, includes a plurality of outriggers mounted to a vehicle frame and having free ends, wherein each of the outriggers has a ground-engaging pad connected to the free ends for vertical movement in relation to the ground. Each of the outriggers has at least one outrigger arm unit movable with respect to the vehicle frame between an idle position suitable for travel between sites, and an operative position suitable for support on the ground, wherein the outrigger arm unit includes an outrigger arm made of a hollow profile which has a lower part of U-shaped configuration and an upper part of calotte-shaped configuration.
