摘要： A coolant circuit for a self-propelled work machine includes multiple electric drive components, including a coolant pump for generating a flow of coolant which circulates in the coolant circuit, a heat exchanger for dissipating thermal energy stored in the coolant, and at least two circuit lines which extend parallel to each other and are embodied to guide the coolant past the drive components respectively assigned to them, in order to absorb thermal energy. A self-propelled work machine, in particular a mobile crane, includes multiple electric drive components and one or more such coolant circuits.

摘要： An emergency-operation valve block includes: a drive port for hydraulically connecting the valve block to an emergency drive of a mobile crane, at least two drive mechanism ports for hydraulically connecting the valve block to one drive mechanism of the mobile crane each, at least two closing valves which are assigned to one of the drive mechanism ports each and designed to selectively open or close a hydraulic connection between the drive port and the drive mechanism port respectively assigned to it, and an actuation valve which is designed to selectively reverse the hydraulic connection between a pressure side and return side of the drive port and corresponding sides of the drive mechanism ports. A mobile crane may include such an emergency-operation valve block.

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 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.
