Abstract: A vehicle having a suspension control system that is especially applicable to an aircargo transport loader which is adapted for storage in a cargo hold of an aircraft. The suspension control system utilizes sensors to monitor the clearance between the vehicle and an underlying or overlying surface such as the ramp leading into a cargo hold or the roof of the cargo hold. The sensors relay information concerning clearance to a central control where the necessary suspension adjustments are made to allow the vehicle to avoid a clearance problem once travel is continued after stopping for the suspension adjustment. The system allows for suspension adjustments to be made either automatically or manually. The invention also includes an under deck support system which allows for limited pitch, yaw, roll and side to side adjustments to be made to the deck with respect to the underlying base frame.

Abstract: A method and transfer vehicle for the elimination of the accumulation of positioning errors of packages in storage places in a computer controlled consecutive store, where the packages are stored consecutively on the base of the rails on which the transfer vehicle travels and where in order to move a package in the center the packages in front or behind must first be removed. The transfer vehicle includes a lifting device which lifts the package off of the base and onto the transfer vehicle for transport. Known store transfer vehicles of this type cause a detrimental accumulation of errors during the positioning of the packages. According to the invention, a package is centered in the direction of the store line relative to the transfer vehicle at least once during the time it is stored on the store line. This takes place most advantageously in connection with each lift via the lifting device.
