Whenever contaminated trucks from construction sites, mines, harbours, landfills, dumpsites or industrial areas drive out directly onto the public roads, MobyDick Wheel Washing Systems can prevent dangerous contamination from getting onto the roads and highways. As a further positive effect, pollution of the air by dust around the areas is also considerably reduced.
A common area of application for wheel washing systems is the bulk industry. Harbours are a typical location, as large amounts of bulk material are on- and off-loaded from ships, stored and transported out using trucks (Fig. 1). Material falling out of the wheel-loader buckets or from the conveyor belts contaminates the stocking area. From there, the trucks carry the mud onto the public roads. The problem is more even severe, because harbours are typically located near urban centres. Similar problems are also common in steel works. The handling of incoming coal and the outgoing ash creates mud and dust in the work area. Due to the high number of transports made by rail in the industry, FRUTIGER has also developed a washing system for rail freight wagons.
As every site is different depending on the type of soiling, the number of trucks per hour and the spatial conditions, FRUTIGER offers an extended range of different MobyDick standard models, in addition to special tailor-made solutions with many aspects. A drive-through system that is easy to use and has very low maintenance requirements is usually recommended for the bulk industry. A typical washing process only takes 30 seconds (Fig. 2). After an incoming truck has automatically activated the washing process, the vehicle can pass through the fully-galvanised system at a walking pace and the wheels and the undercarriage are washed out using a well-arranged low-pressure nozzle pattern. The wash water remains in a closed circle and is constantly recycled for the next wash, minimising water use.
Handling large amounts of bulk material, coal or ashes and the influence of local winds can cause a general dust cloud above an area. This can cause serious health, environmental and political problems. Dust sources constantly vary in their type and scope; therefore, they require specific solutions. For this reason, in addition to its wheel washing systems, FRUTIGER, together with its Belgian partner Savic Engineering, offers a wide range of MobyDick Dust Control Cannons and complete dust control strategies for the steel, mining, bulk handling, recycling and construction industries. These range from small dust cannons with a 10 m throw distance to big, powerful dust control cannons with a throw distance of over 70 m. MobyDick Dust Control Cannons produce fine water droplets in a sufficient quantity that are adapted to the dust source and the dust type. This allows optimisation of water and energy consumption, and therefore, a significant reduction in operating expenses. Individual machines are available in different sizes and in many different configurations. Custom-made manual or automatic systems fully adapted to the specific situation in order to solve customers’ dust problems are also available.
