In the Pacific Northwest, being prepared for any type of weather is a must for today’s fleet managers. Automatic tire chains provide instant traction for buses and vans when the road turns slippery. Western Bus Sales is proud to represent OnSpot Automatic Tire Chains, “The Original Since 1977.” We are one of the most experienced and knowledgeable OnSpot dealers on the West Coast.
So How Does It Work?
The system permanently fastens to the rear suspension of the vehicle. The driver can activate a dashboard switch that opens an electric over air solenoid mounted on the frame rail. Air pressure from the vehicle’s on board are brake system or an auxiliary air source flows to two air cylinders that lower two chainwheels down until they contact the tire sidewall. The friction between the tire and the chainwheel causes the chainwheel to rotate. Each chainwheel has 6 lengths of chain attached to it. The centrifugal force created causes the chains to flail out and pass between the tire and road surface to enhance traction in snow and ice in forward or reverse. The additional traction also reduces stopping distance in these same slippery conditions. When the switch is turned off, the solenoid exhausts the air in the cylinder and the spring in the cylinder returns the chains to the resting position.
