Kelston is an approved gearbox supplier to Johnston Sweepers, a leading name in truck-mounted road sweepers.
The V Range Sweeper uses a secondary engine, driving a Johnston fan drive gearbox (manufactured by Kelston) to create the vehicle’s suction power.
Unlike a traditional transmission system, a hydrostatic drive offers a continuous power curve and hence an infinitely variable forward speed control. Johnston's V Range hydrostatic sweeper model features a Kelston gearbox powered by the main truck chassis engine. Designed by Johnston specifically for road sweeping, its hydro-drive allows for cruise control and travel speeds up to 40 kph.
