A concrete saw trailing having a deck for receiving the saw and safely transporting the saw. The saw trailer additionally includes a vacuum excavation system having a vacuum tank for recovering debris from a worksite, a power washing system for cleaning operations, and a cooling water supply system for coupling to and supporting use of the concrete saw. A pair of split ramps permit access to the deck from the street side of the trailer, and two opposing saddle bag water tanks provide enough water for the use of vacuum excavation system, power washing system, and cooling water supply system.

A street sweeper configured to clean a street can include: at least one broom or sprayer configured to clean a street, a street surface deviation detection device coupled to the street sweeper, the street surface deviation detection device being configured to detect visual signatures of defects in a surface of the street; and a position device to measure the position of the street sweeper, wherein the position device is programmed to send the position to a central server.

The present disclosure relates generally to a roadway debris clearing system that can be concealed within, or behind, a standard push bumper of a safety patrol vehicle. The roadway debris clearing system may include a debris clearing device that is disposed between the vehicle motor and the front bumper. The debris clearing device can be deployed from a retracted position to an extended position where the device is capable of pushing debris from a roadway. The debris clearing device, when in the retracted position, may be concealed behind the front bumper of the vehicle. The roadway debris clearing system includes a camera system to observe an area in front of the vehicle as well as under the front bumper while clearing debris using the debris clearing device.

A surface cleaner and method of operation are provided wherein the surface cleaner may include a rotatable nozzle assembly with one or more nozzles which may expel water onto a target surface to be cleaned.

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.

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.

An apparatus for clearing around an associated stationary object includes a housing having a top wall, a side wall, and at least one opening extending through the side wall. At least one paddle member is mounted to and extends radially outward from an exterior surface of the housing. The paddle member is adapted to clear around the associated stationary object. The apparatus further includes a plurality of elongated cables mounted to a support that is selectively secured to an interior surface of the housing. The elongated cables are adapted to clean around the associated stationary object.

A re-conformable material removal system comprises a head comprising an axial slot extending from an inner chamber to the exterior thereof. A plurality of material removal blades are arranged in side-by-side relationship and have first, proximal ends disposed in the inner chamber, axially extending blade shafts extending through the axial slot and second, distal ends projecting outwardly from the housing to define a removal edge. A biasing member is disposed within the inner chamber to yieldably bias the blades to a fully extended position through the axial slot; wherein placement of the re-conformable material removal system against a surface results in yielding of the biasing member and movement of the blades into the housing when the surface is uneven, resulting in a conformed edge that is continuously adjustable and conformable to the contour of the surface.
