ABSTRACT:
A truck adapted to stow, stack, etc., large containers comprises a chassis including a pair of substantially parallel cross beams extending in spaced relation to one another from a pair of elongated longitudinal beams which cooperate with the cross beams to provide a chassis of substantially C-configuration in horizontal cross section. The longitudinal beams are of telescopic construction with the parts thereof being selectively displaceable to vary the effective length of the longitudinal beams thereby to vary the spacing between the cross beams. The cross beams in turn are associated with vertically oriented telescopic support legs having support wheels at their lower ends which may be selectively displaced for steering purposes by means of associated electric servos. The servos are controlled by an electric steering system which includes a damping network comprising either a plurality of selectively switchable resistors, or a plurality of selectively variable potentiometers, which are in turn controlled by sensors carried by the telescopic parts of the longitudinal beam to switch over the steering system for adaptation to the steering geometry of the selected effective length of the longitudinal beams.
