Customised configurations for runway / airport applications
Runway metal recovery
Front mounted on a Johnston V Range, the powerful electronic magnet efficiently collects all metal debris in its path, and in conjunction with the swept width of 3600mm achieved by using the channel brush and dual sweep brushes, safety and productivity are fully maximised.
The V Range sweeper effectively deals with Glycol/anti-freeze recovery from ground surface areas. Using a powerful pump and suction nozzles, the system efficiently sucks up surplus liquid laying on stand areas, preventing damage to expensive surfaces and avoiding drainage system contamination. Fortunately once the glycol is collected, this expensive chemical can be re-used.
Airports must ensure runway lights continually remain bright and visible, and by its nature this task presents difficulties with access and timing. The Johnston V Range runway sweeper has the ideal solution, with a raised brush fitted to the front of the sweeper specifically to clean runway lights, enabling this important task to be carried out efficiently and safely.
Adjustable brush pressure systems on the main broom and channel brushes combined with detergent spray bars complete with a measured detergent dispenser, enables the V Range airport sweeper to provide a stand scrubbing function, effectively removing oil, fuel and chemical spills. Using fluid recovery nozzles the detergent mix is then safely recovered from the treated area.
Sweeping and dust suppression
A swept environment is required around aircraft and has to be achieved with minimal disruption and dust. The Johnston V Range airport sweeper achieves an efficient one-pass sweep collecting debris and trapping dust. Fitted with the latest Johnston dust suppression system, the finest dust particles are lifted and retained in the sweeper hopper. Johnston's dust suppression system meets EUnited PM10 standards for air quality, and by including the micro-dust water spray option, even higher dust control management can be achieved.
In-cab Control Systems
The control systems are designed for ease of use, safety and maximum performance. All sweeping operations are controlled from the master module inside the cab. This incorporates an audible & visual raised hopper warning and auxiliary engine fuel gauge, hour counter & tachometer as standard. The bodies come in a range of hopper capacities, from 6m³ to 8m³.
Water Tanks & Water Drainage
The water tanks incorporate anti-surge baffles and comes fitted with a visual level gauge, access ports for cleaning the tank and a drain valve mounted at the rear of the machine. Optional rear door drain valves at 76mm and 102mm (3" or 4") diameter allow faster de-watering without entering the body and Johnston's Pressadrain water purging system enables the easy removal of water from the systems in freezing conditions.
Manual system located on the rear door allows you to shake the rear screens for easy cleaning without entering the body. The rear door is self-sealing with automatic locking. Safety restrictors ensure that it lowers slowly in the unlikely event of pneumatic failure.
