摘要： The invention relates to a bolting device having two bolts which are held rotationally secure and coupled to each other via a spindle element, wherein: a first bolt is connected via a threaded engagement to a corresponding thread of the spindle element; rotating the spindle element about its central longitudinal axis causes the first bolt to move along the longitudinal axis; and a second bolt is rotationally mounted on the spindle element in a fixed axial position. The invention also relates to a crane jib head comprising such a bolting device, for bolting a lattice masthead to a head adaptor.

摘要： A height access device enables motorized access to the driving station of a tower crane atop a mast formed of superposed mast elements. It includes a lift cabin installed inside the mast of the crane and movable vertically along the mast. The height access devices further includes a working platform positioned above and separably connected to the lift cabin. A coupling device provides a non-permanent connection of the working platform to the lift cabin and immobilizes the working platform relative to the mast at a required height. The height access device enables the crane driver to ascend and descend with the lift cabin alone when disconnected from the working platform and with the lift cabin and working platform together, particularly during the assembly and dismantling of the mast.

摘要： A telescopic jib bracing unit for a mobile crane includes a holding frame which is embodied for fastening to the telescopic jib of the mobile crane and exhibits an open cross-section, the cross-sectional opening of which enables the jib to be retracted into the holding frame, and two bracing supports which are connected by the holding frame to form a structural unit. Two frame parts which form the open cross-section of the holding frame are coupled to each other via a coupling point such that they can be moved with respect to each other. A bracing unit transport system, a mobile crane and a fitting method are also provided.

摘要： A locking head is configured such that it can be moved within and along the longitudinal axis of a telescope, which comprises at least two telescope sections, by means of a telescoping device, comprising a base body, at least one releasing device which is configured to release a telescope section lock and at least one coupling device which is configured to couple a telescope section with the telescoping device. The locking head comprises an operating member which mechanically acts on the releasing device and the coupling device in order to operate the releasing device and the coupling device. The operating member comprises a first link guide for the releasing device and a second link guide for the coupling device, wherein the links for the first and second link guides extend in a single plane or in parallel planes.

摘要： A self-propelled work machine, in particular a mobile crane, comprises an undercarriage configured for moving the work machine, a superstructure which is rotatably mounted on the undercarriage, and a drive device comprising a drive motor. The drive device comprises a moment transmission which is formed between the superstructure and the undercarriage and configured to transmit power outputted by the drive motor between the superstructure and the undercarriage in the form of a moment. At least one and, in particular, all of the elements to be driven receive a moment about an axis which extends in the region of a rotary bearing of the superstructure and the undercarriage, in particular about the rotational axis of the superstructure.
