Tire chain system
The Automatic Tire Chain System is designed to offer the traction of a single set of conventional snow chains. An electric switch mounted in the cab provides 12 volts to an air solenoid mounted on the vehicle’s frame rail. Compressed air to the solenoid is supplied from either the vehicle’s onboard air system or a 12-volt compressor kit. When the dashboard switch is activated, the solenoid opens. This allows compressed air to enter the air cylinder and lower the chainwheel, so it contacts the inside of the tire. The friction between the tire and the rubber-covered chainwheel causes the chainwheel to rotate, creating enough centrifugal force to flail the chains out. Six lengths of chain spaced at 60-degree intervals on the chainwheel ensure that there are always two chains between the tire and road surface whether you are accelerating, braking, or are in a wheel lockup condition. The traction from the chainwheel is obtained in forward or reverse. For more information, visit www.onspot.com.
