Claim 0:
1. A mobile crane comprising:
a drive assembly frame which is configured at least in sections as a hollow profile having profile sides which are formed from multiple profile segments up to a predetermined height, wherein the profile sides are connected to each other such that a horizontal width of the profile increases from a lower side of the drive assembly frame; and
a mobile crane drive assembly axle comprising mutually independent suspensions configured to couple respective wheel carriers arranged on both sides of the drive assembly frame to the drive assembly frame of the mobile crane,
wherein the mutually independent suspensions are each embodied as a double transverse control arm wheel suspension comprising at least one upper transverse control arm overlying a lower transverse control arm,
wherein the at least one upper transverse control arm is arranged in an upper control arm plane of the suspension, and the lower transverse control arm is arranged in a lower control arm plane of the suspension, arranged one above the other in respective control arm planes of the suspension,
wherein the suspension is configured to couple a wheel carrier of the respective wheel carriers to the drive assembly frame with the at least one upper transverse control arm and the lower transverse control arm, wherein the at least one upper transverse control arm and the lower transverse control arm are connected to the drive assembly frame such that the suspensions can be rotated about an axis which extends substantially parallel to the longitudinal axis of the drive assembly frame,
wherein the at least one upper transverse control arm is configured to extend from the wheel carrier to a vertical side wall of the drive assembly frame below the predetermined height,
wherein the lower transverse control arm is configured to extend from the wheel carrier to the lower side of the drive assembly frame, and
wherein drive assembly elements which perform functions of steering rods and track rods are arranged in the lower control arm plane and reach to the lower side of the drive assembly frame.
