INVENTION: RESILIENTLY MOUNTED, PIVOTABLE STEERING ROLL, ESPECIALLY FOR DRIVERLESS VEHICLES ABSTRACT OF THE DISCLOSURE This device prevents individual components of a load from being thrown off during halting of a conveying vehicle at a high rate of deceleration. A blocking device for the suspension of the currently forward steering roll prevents the vehicle from forwardly and downwardly dipping about the axle of the center-mounted drive wheels. The blocking device automatically adjusts itself corresponding to the direction of motion. A sliding stop vertically displaceably mounted on a pivotable part of the steering roll and a stop component fixedly mounted on the vehicle body cooperate to block the suspension of this steering roll when the currently forward steering roll experiences a predetermined degree of suspension displacement. At the currently rear steering roll, the stop component and the sliding stop are positioned at 180° to one another, thus precluding inadvertent engagement and permitting full suspension displacement. When changing direction of travel t both steering rolls pivot automatically about a vertical axis, blocking the suspension of the steering roll currently forward in the new direction of travel and permitting the rear steering roll to exploit its full suspension displacement range.
