The invention relates to a mobile crane or aerial lift platform vehicle wherein at least one of the axles is extendable and wherein a cylindrical housing carries the extendable axle beam and a steering actuator is carried on at least one of the beams and is connected to a steering link connected between the wheel and the outer end of the beam. The arrangement is such that the distance between the actuator and the steering link is not altered by extension or contraction of the beam relative to its housing.
