This is a model of a motorized concrete mixer truck. A recycled motor paired to a battery moves the truck forward and reverse. The driver’s cabin is decorated with steering wheel, cushioned seat, headlights, license plate and ladder. This motor is linked to shaft that ends at a yellow gear (visible in the photos below). This gear rotates the concrete mixer and connects to an adjustable trough from which the concrete can be poured when the truck arrives at the construction site. All details are realistically measured against actual trucks.
