Abstract: A mobile crane drive assembly axle includes mutually independent suspensions of wheel carriers arranged on both sides of the drive assembly frame of the mobile crane. The suspensions each include at least one transverse control arm which couples the wheel carrier onto the drive assembly frame and is connected to the drive assembly frame such that it can be rotated about an axis which extends substantially parallel to the longitudinal axis of the drive assembly frame.

Abstract: A method for ascertaining the load capacity of a functional element of a crane, the load capacity of a sub-assembly of a crane or the load capacity of a crane, wherein: a maximum bearing load is calculated for a specifically occurring configuration and/or specifically occurring state parameters and/or specifically occurring operating parameters on the basis of a predetermined formula; and the calculation is verified on the basis of stored bearing load values.

Abstract: 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.

Abstract: The invention relates to a mobile crane travel gear axle with suspensions, which are independent of one another, of the wheel carriers arranged on both sides of the travel gear frame of the mobile crane, wherein the suspensions each have at least one transverse link which couples the wheel carrier to the travel gear frame and which is connected to the travel gear frame so as to be rotatable about an axis extending substantially parallel to the longitudinal axis of the travel gear frame.
