摘要： A mobile crane comprising a telescopic boom which has a main casing with linearly moveable inner casings. Guying equipment can be added to the telescopic boom, where at least one securing region arranged on the main casing is provided for the fixing of the guying equipment. In order for the adding and removal of the guying equipment to and from from mobile crane to be carried out more easily and safely, at least one coupling region is arranged on one of the inner casings for adding and/or removing the guying equipment and which can be connected to the same. In this way, the guying equipment can be received directly from a transport unit by the at least partially extended telescopic boom, the guying equipment can be moved onto the main casing by retracting the telescopic boom and coupled to the same.

摘要： A vehicle crane system includes a vehicle crane having a detachable attachment part, in particular a main jib, and an attachment part transporting unit which is designed to receive the attachment part when the latter is detached from the vehicle crane and comprises a mobile transporting device for transporting the attachment part. To remove and mount the attachment part of the vehicle crane and to transport it, the transporting device is equipped with at least one loading arm, the free supporting end of which is provided for at least indirect temporary coupling to an attachment part which is to be received or is already received. The loading arm is mounted pivotably on the transporting device such that an attachment part to be loaded or unloaded can be moved down onto the transporting device or from the transporting device.

摘要： A vehicle crane having a superstructure with a jib system including a main jib mounted in a luffable manner on the superstructure, with a jib head and a luffable additional jib and at least one luffing support supported in the region of a luffing axis of the additional jib. At least one guying support of the jib system is arranged in such a manner that a tensioner starting on the one hand from the superstructure and/or from a counterweight and connected on the other hand to the additional jib is guided via the at least one guying support and the at least one luffing support. A main jib extension is incorporated between the jib head and the additional jib with the at least one guying support supported at the main jib extension to obtain a longer design of the jib system with the highest possible permissible bearing load.

摘要： A vehicle crane having a lower carriage with a longitudinal axis and a superstructure that is rotatable about a vertical axis includes at least one base support and at least two side supports arranged on the lower carriage, where the base support and the side supports can be supported with respect to the ground. The two side supports are each arranged on the lower carriage via a support carrier and oppositely in relation to the longitudinal axis of the lower carriage, and precisely two side supports are arranged on the lower carriage. Each base support is arranged oppositely with respect to the two side supports in relation to the vertical axis and as seen in the direction of the longitudinal axis, and a rotary connection support for the superstructure is arranged on the lower carriage and the two support carriers are arranged remotely from the rotary connection support.

摘要： 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.
