To help you understand why some Tanker Trailers have Baffles/ bulkheads and others do not?“The sloshing effect” In Tanker Trailers.The sloshing effect results from the movement of the liquid in partially filled tanks. This movement can have bad effects on handling. /transcourt
If you’ve ever pulled a tanker trailer, you’ve experienced the sloshing effects. This aspect of hauling liquid loads can be very intimidating at first for the driver. Some tankers have Bulkheads or baffles and some don’t. /transcourt
