摘要： A mobile crane supporting device includes a first support segment, a second support segment and a fixing device for preventing a movement of the second support segment in the direction of movement and in any relative position between the first support segment and second support segment, wherein the fixing device includes a clamping body which is held in abutment with a ramp, which is formed between the first support segment and second support segment, by a holding device and mounted relative to the first support segment and second support segment in such a way that a travelling movement of the second support segment in a direction pointing away from the support foot causes an increase in the force applied to the ramp by the clamping body and thus fixes the second support segment relative to the first support segment. A mobile crane also includes such a supporting device.

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 crane includes a jib which is mounted on the crane structure so as to be rotatable about a bearing point, a counterweight arrangement which can be positioned variably in relation to the bearing point, and a hoisting cable which runs out from a hoisting winch and is guided via the jib. A counterweight adjustment device, which is coupled to the counterweight arrangement, includes
a lever element mounted rotatably about a pivot point,
a hoisting cable guide arranged in the course of the hoisting cable between the hoisting winch and an upper jib section, with a first deflecting pulley arrangement mounted on the jib and a second deflecting pulley arrangement mounted on the lever element, wherein the hoisting cable is guided in an alternating manner via the first and the second deflecting pulley arrangement,
and a coupling element acting on the lever element and connected to the counterweight arrangement.-

摘要： A tracked drive assembly for a work machine comprises a crawler frame, a crawler track, a drive wheel and a guide wheel, and an arrangement of running wheels coupled to the crawler frame, wherein the tracked drive assembly has a sensor system comprising a sensor for each of the outer running wheels of the running wheel arrangement, which are positioned or located adjacent to the drive wheel and the guide wheel, and at least one other running wheel which is arranged between the outer running wheels, wherein the force introduced into the crawler track via the respective running wheel can be determined by way of the sensor. A method for determining the ground pressure distribution below a work machine includes exposing the sensor to a compressive load at a running wheel.
