The Unitrac is equipped with a joint with level compensation, which keeps the vehicle in the lane in uneven terrain. The cabin, which is equipped with folding mirrors, can be folded to the side and provides a view of the engine with its richly detailed design. The cabin roof can be removed so that Siku driver figures can be placed in the model. The loading function is shown in detail on the loader wagon, which has a scraper floor indicated by engravings. The movable gripper arm at the rear of the vehicle can be swivelled into working and driving position. With the hitch on the front of the model, the available Siku front units can also be used with this vehicle.
