– 3-Brush Automatic Fleet Washing System for Commercial Vehicles: The SARV STL-ABWM-P3B is a roll-over gantry-type washing machine developed for the exterior cleaning of trucks, buses, and large commercial vehicles. Its automatic washing arrangement combines rotating brushes, water spraying, and detergent application within a designated washing bay.
– Automatic Control Panel Operation: The washing system operates through a control panel consisting of contactors, relays, and timers or a PLC-controlled panel. The washing sequence begins when the operator activates the start button after positioning the vehicle inside the washing bay.
– Three-Brush Washing Mechanism: The machine features a 900 mm diameter horizontal brush and 1000 mm diameter vertical brushes. These brushes use 305 mm long, X-section profile polyethylene elements to perform the washing operation as the gantry moves along the vehicle.
– Automatic Detergent and Water Application: An electronic metering pump controls shampoo and detergent delivery. During the washing sequence, the water pump, detergent pump, and brush spray system operate together to apply the washing solution to the vehicle exterior.
– Vehicle Width Accommodation: The side brushes move outward upon contact with the vehicle to accommodate its width. Their movement is hydraulically damped to prevent brush bounce during operation, allowing the washing mechanism to follow the vehicle’s exterior.
– Oscillating Water Blaster System: The washing machine incorporates oscillating blasters that spray water across the front, roof, and rear of the bus. During the return movement, the washing system performs another brushing operation while rinsing the vehicle.
– Automatic Washing Cycle for Fleet Operations: The STL-ABWM-P3B operates through a complete automatic washing sequence, including brush movement, detergent application, water spraying, rinsing, and return travel. The machine has a specified wash cycle of 6–7 minutes and is intended for commercial vehicle washing facilities handling trucks and buses.
