Abstract: A vehicle for re-establishing safe roadway conditions after a car accident by cleaning the roadway. The vehicle includes a first tank containing clean water; a second tank containing a washing liquid for washing oil and other fluids off the road; and a suction tank containing emulsion obtained by collecting the washing liquid and the oil materials. The vehicle also includes a high-pressure water gun; a suction system for removing the emulsion from the roadway; and a suction tube for removing debris from the road, such as broken glass and pieces of plastic. The high-pressure water gun and suction system are powered by an internal combustion engine which powers a pump and three-way distributor which pumps pressurized oil through a hydraulic circuit. There is also a level sensor to measure the quantity of liquid in the suction tank so that the combustion engine is switched off when suction tank is full.

Abstract: A Multi-purpose truck for re-establishment of safe and practicable road conditions, after car accidents, through cleaning of the road platform, said truck being equipped by: several tanks, a high-pressure water gun for spraying cleaning products, a suction system suitable to remove, from the road platform, an emulsion that results from the addition of cleaning products to the debris on the road platform, and tanks containing the resulting emulsion to be temporarily stocked at a location, before being definitely delivered to special and authorized plants for disposal. The power supply, necessary to make the multi-purpose truck work properly, can be directly provided by the engine of the truck and/or any other point of energy transmission in the kinematic chain, or it can be directly provided by a pneumatic circuit previously installed on the same truck. The extracted energy can be used as a power supply for mechanical, electrical, or hydraulic devices.

Abstract: Multi-purpose module (450), preferably installed on a light commercial vehicle, for re-establishment of safe and practicable road conditions, after car accidents, through cleaning of the road platform, said vehicle being equipped by:—a tank (415) containing clean water; a tank (414) containing water mixed to a specific washing liquid—ecological surfactant—and a specific treatment liquid for the road platform—so called molecular chain destroyer, to be sprayed on oil and related oil products (428); a suction tank (405) containing emulsion (430) obtained by collection of the washing/treatment liquids and the polluting oil materials;—a high-pressure water gun (408), including a rain jet adjustment, providing a jet of the above said solution (428) on the road platform, where polluting functional liquids (429)—lubricating oils, fuels, cooling substances, etc.
