Javier Gutiérrez CasalOne machine that invariably works in extreme cold weather is the snow blower. Looking at such a machine, you can clearly distinguish two parts: something that resembles a meat grinder on the front, and an industrial vehicle that is adapted to perform the function of supporting structure.

My design, in which all the traditional elements of a snow blower are integrated, enhances safety, maneuverability and efficiency with the capacity to remove 50% more snow. It also means that the vehicle occupies less space when not in use.
This 6x6 vehicle is powered by two diesel engines – one powering the transmission, steering and suspension system, and the other, the hydraulic system that drives the snow blower attachment. All wheels are driven by electric hub motors and steered by electric motors and a reduction gearbox situated on top of the articulated single-arm suspension system. The wheels can be steered independently and the ground clearance of the vehicle is regulated by hydraulic cylinders placed in each articulated single arm, which can modify the distance and angle between the attachment and the floor.

The front attachment consists of two halves, each housing the augers and auger housing. Each of them is moved by a hydraulic system that governs the positioning of the front wheels, placed tangentially to the trajectory described by each half. When the system is completely open, three drives will be positioned between the two halves to move the snow displaced by the augers and blades to the launcher barrel. Under the cockpit there is a fourth impeller to assist the movement of the snow. This configuration, where the articulated chute is located behind the cab, will not hinder the driver’s vision when the snow blower is at full steam.
