Abstract: Methods and devices to physically stabilize a unit load of stapled unit loads such as at least two standard containers applied atop each other and on top of at least one Automatically Controlled Vehicle (AGV), during transport of the load in all directions on the ground. The AGV arranged below the unit load has at least one wheel-bogie having at least one wheel at each corner, the bogie being controllably pivotable at its geometrical center to a frame of the AGV with each wheel being controllably pivotable at its respective fixation points. During transport in a longitudinal direction of the total unit, each bogie is translated to a diagonal position in relation to its position of introduction as the wheels simultaneously are controlled so as to maintain their rolling direction in the direction of transport, so as to enhance the traction of the AGV.
