A mobile vehicle mounted dry filtration system to support a grinder system used for removal of markings, creating rumble strips, or the like. Blowers create a vacuum for drawing debris and dust from the grinder system into a debris bin. Large debris is removed from the vacuum draw and remains in the bin for later disposal. Small particles and dust are drawn into parallel positioned filter cyclones that have a cyclonic separation followed by flexible and inexpensive bag filters. The flexible filters are cleaned using vibrating diaphragms mounted on the top of the filter cyclones subject to a reverse air flow by the blowers using slide valves. A polishing tank containing water receives the exhaust from the filter cyclones for removal of airborne particles and sound suppression.

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.

A washing apparatus has a vacuum unit and a pressure washer unit. The vacuum unit has a mud tank, a first centrifuge, and a second centrifuge, and the pressure washer unit has a first water tank having a bottom, a top and a side, and a second water tank having a bottom, a top and a side. A frame having a top, a base and four corners supports the vacuum unit and pressure washer unit. The first centrifuge and the second centrifuge are fixed in respective first and second corners of the frame, and the first water tank and second water tank are fixed in respective third and fourth corners of the frame.

A mobile cleaning system to be used for cleaning organic liquids from a hard surface includes tanks for storing water, and for storing used, dirty water after cleanup. A water-based cleaner is sprayed onto the spill, which can be, but need not be, done in connection with the cleanup system. A high throughput vacuum system removes the hot water and the spill materials concurrently as the hot water is applied to the treated area. The vacuumed liquids are stored in an on-board tank for later disposal.

An electrical generator system for a vehicle comprises a power plant having a fluid cooling system, an alternating current generator mechanically coupled to the power plant, a generator control coupled to receive electrical input from the alternating current generator, and an engine speed control configured to receive a control signal from the generator control and to provide an input to the power plant to control speed of the power plant. The fluid cooling system can be configured to cool the alternating current generator. In one example, the generator can be used to electrically power a motor that can be used to mechanically power a liquid pump and an air blower. In one example, the fluid cooling system can be used to cool the generator and the motor, and heat liquid pumped by the liquid pump. In one example, the heated liquid can be used in conjunction with a carpet cleaning tool that utilizes a vacuum generated by the air blower.

An installation for the maintenance of road surfaces, or located on several sections of road, on the median line of the road or on one of its sides, which installation operates according to meteorological parameters measured in real time by the weather station associated with each section or during the issuing of a warning code in the geographical area of each section and which is composed of an air compressor, a compressed air tank, one or more reservoirs for the intervention fluids, connected by connections to a pump unit, controlled by a GSM module with remote relay according to the commands of a server, the fluids circulating through connections and pipe sections mounted underground in the roadway, compression collars being arranged on each pipe section and connected to spraying sub-assemblies consisting of direction valves, flow restrictors, movable quick couplers and nozzles, the installation allowing automated actions based on the interpretation of meteorological data received from weather stations.

Methods of treating bitumen-containing surfaces to improve surface friction are described. The method may include applying a non-caustic composition to the bitumen-containing surface, wherein the non-caustic composition is capable of dissolving components of the bitumen-containing surface, such as tar and oil. Following application of the non-caustic composition to the bitumen-containing surface, the method may further include steps of spraying the bitumen-containing surface with water and removing loose or loosened debris from the bitumen-containing surface. In some embodiments, water is sprayed at ultra high pressure, and in some embodiments, debris is removed through the use of cyclonic airflow.

An apparatus for rejuvenating markings on roads includes at least one cleaning unit, a collection tank, a vacuum member, and a connection point. At least one cleaning unit includes a frame, at least one skirt member, at least one spray connection, and a wand member. The skirt member is coupled to an external surface of the frame. The spray connection is disposed at least partially on a top surface of the frame, and the wand member is coupled to the underside of the spray connection. The collection tank includes a plurality of entry points and at least one vacuum connection. Each entry point is configured to mate with a hose. The vacuum member works with the collection tank such that material is vacuumed from underneath the cleaning unit into the collection tank and then into a storage tank. The connection point is configured for attachment to a maneuvering member.
