Abstract: A vehicle tilting device for tilting a delivery vehicle for increasing access to items from a storage container transported on the delivery vehicle. The vehicle tilting device comprises a base structure and a tiltable platform connected to the base structure, wherein the tiltable platform comprises guiding features adapted to guide the delivery vehicle onto the tiltable platform. The tiltable platform is arranged to be connected to a delivery grid cell of a delivery rail system such that that there is a path to and/or from the tiltable platform for the delivery vehicle via the delivery grid cell. The invention is also related to an access station, a delivery system and a method of accessing a storage container.

Abstract: An operator controllable machine is retrofitted to be operator controlled or to be automatically controlled. An electrical joystick output is provided by a manually actuated joystick control, including a joystick, to a machine control in the manually controlled machine. An interface is added between the joystick control and the machine control to permit an external source, such as a GPS receiver or a laser receiver, to apply an electrical automatic control output to the machine control, as well. The interface includes a number of optical isolation circuits and a microprocessor. The isolated microprocessor output is supplied to the machine control, which produces valve control signals to control the hydraulic valves of the machine. The application of hydraulic fluid to the hydraulic cylinders of the machine is then controlled by either the joystick control output or the automatic control output.

Abstract: A system for storing a carrying truck uncoupled from a self-propelled truck moving along a given passage. So that such uncoupled carrying truck may be stored at a storage area outside and angular relative to the passage, the system includes a direction change device disposed at a point of the passage where the carrying truck is uncoupled from the self-propelled truck, and a truck hitching device disposed in the storage area such as to orient towards that point of passage. The direction change device includes a rotary disc member and an elevating element for raising the carrying truck and orienting the same towards the storage area. The truck hitching device includes fore-and-aft movable elements for hitching and drawing the carrying truck which has been changed its direction by the direction change device, towards the storage area.
