A system for cleaning tires of a vehicle traveling along a longitudinal direction over the system includes modular tire cleaning units with debris removal elements. Each unit includes debris removal elements, such as a first chain assembly supported between supports and over a substrate and extending substantially transverse to the longitudinal direction, the first chain assembly defining a first tire track. A second chain assembly is supported between second sets of supports and over the substrate and extending substantially transverse to the longitudinal direction, the second chain assembly defining a second tire track parallel and spaced apart from the first tire channel. The system may include a second modular tire cleaning unit with longitudinally extending chains and/or a trough holding water and/or sprayers at the side of the system.

A liquid cleaning and watering system for living plants rests on a surface covered by a non-porous material. A plate layer covering the non-porous layer has two or more layers, each layer having runners arranged in a grid. The grid of each successive layer is offset at an angle with respect to the grid of a previous layer. An upper layer covers the plate layer and has a plurality of holes for the passage of liquids into the liquid cleaning system. As the living plants are watered or cleaned, excess liquids containing water and oils that were excreted by the living plants enter the liquid cleaning system through the holes, the liquid traverses the grid layers, flowing towards a drain. Contaminants within the liquid collect within the grid of the layers of the plate layer for later disposal.

Scrapers for removing adhered material from surfaces employ continuous and discontinuous material removal edges to remove different types of material. Continuous and sometimes discontinuous material removal edges are constructed and arranged to conform to the curvature of a surface from which material is to be removed, when a user forces the scraper against the surface. Some scrapers include multiple material removal edges designed to simultaneously contact the surface. The use of multiple points of contact combined with locations of handles provide stable designs that reduce hand and wrist strain.

A dryer assembly for a vehicle wash system for emitting high velocity air onto a vehicle exterior includes a housing having an air inlet and an outlet. The air inlet is in communication with a motor assembly having an operating and a non-operating mode. The assembly also includes a gate mechanism in communication with the air inlet. The gate mechanism includes a plurality of pedals that are each pivotable between a first position and a second position. The gate mechanism is in communication with a controller, which directs movement of the plurality of pedals from the first position where the plurality of pedals surround the inlet opening such that air can flow into the housing and the second position where each of the plurality of pedals covers a portion of the inlet opening such that in their entirety the plurality of pedals obstruct the inlet opening to prevent air for flowing into the housing.

This washing machine for a railway vehicle includes a water texturing system, mixing water with particles able to produce textured water having super-hydrophoby properties making it possible to implement a lotus cleaning effect on the surface on which the textured water flows; a textured water spraying system, fed by the water texturing system and using at least one appropriate spraying device to spray the textured water on a surface of the railway vehicle to be cleaned.

A service station for vehicles of an autonomous vehicle fleet. The service station includes at least one service module that is designed to identify the dirtiness of at least one vehicle component of the vehicle. The service module also includes at least one mobile robot and/or a robot arm on which a tool is arranged for identifying dirtiness. The tool includes at least one optical sensor and preferably at least one light source and/or at least one vapor emitter.

Devices, methods and systems are provided for preserving the surface of vehicles. The system includes a mobile housing such as a pull behind trailer that contains a purified water storage tank, a clothes washer and drier, a water heater, a multimedia filtration system, a Reverse Osmosis (RO) System, a discharge pump, and a booster pressure pump. Smaller satellite tank trailers may be serviced by larger system described herein to allow simultaneous washings. A high concentration SiO2 ceramic coating is applied with SiO2 concentration ranging between 49.9% and 64.1%.

A mobile cleaning system has a mobile unit allowing for movement of the cleaning system to and around a static vehicle for cleaning, a main cleaning assembly for applying cleaning fluids to a surface of the static vehicle and for scrubbing the surface of the static vehicle (where the cleaning assembly has the ability to pivot, rotate, and/or tilt for various cleaning purposes), a self-contained fluid supply system providing the cleaning fluids used by the cleaning assembly, and a operator control assembly allowing an operator to ride the mobile unit and selectively operate the components of the cleaning system.
