Wheel Washers – Type MB

Description

The mistral Type MB is a mobile, totally above ground wheel wash system for removing light to medium/heavy soiling from vehicle tyres. The system delivers 1 or 2 full tyre revolutions of cleaning power (depending on model) and has a maximum throughput of 50 trucks per hour.

Washing takes place as the vehicle slowly drives through the system and the wash cycle is automatically started via an optical sensor and variably controlled with a timer. The system includes entry and exit ramps, a wash platform with an integrated screw-conveyor for transferring wash water and solids into the recycling tank, side spray walls and a recycling tank for water treatment with an integrated scraper conveyor for automatic sludge removal.

Function

A specially developed nozzle system, consisting of bottom nozzles in the wash platform and side nozzles in the spray walls, ensures for an efficient water spray profile for targeted cleaning of the tyre profiles plus outer and inner wheel surfaces. The direction of the side nozzles can be individually adjusted to optimise cleaning. The angled rumble grids that are integrated into the wash platform construction shake vehicles’ wheels and flex open tyre profiles to supplement the cleaning effect.

Washed off sludge is transferred via a screw-conveyor into the system’s recycling tank which is located adjacent to the wash platform. The waste sediment is automatically evacuated via the scraper conveyor and the water is circulated from the tank for reuse in the wash system. The water level in the tank is automatically regulated through a float valve. The use of a flocculent greatly increases and optimizes the sedimentation process and the flocculent is fed via an automatic dosing unit which is included in our standard scope of delivery.

Personnel

The MB System has a totally automatic operation. Operators need only to periodically check and control the nozzles and conveyor system plus ensure a sufficient water supply to the recycling tank. A representative of mistral will instruct the customers’ personnel on routine checks and cleaning of the system during commissioning and handover.

Preparation for installation

There is no excavation work at all necessary for the MB System. All that is required is a load-bearing, level surface onto which the System can be placed plus water and electrical power supplies in accordance with the mistral installation guideline drawing.
