Activating the dashboard switch releases compressed air into a cylinder. This action lowers the chainwheel and presses it against the tire. The sidewall’s friction with the rubber-covered chainwheel causes it to rotate. This rotation creates centrifugal force, extending the chains beneath the tire for improved traction.
The automatic operation begins when the driver activates the Switch, usually through a button inside the vehicle. Sensors detect wheel speed, and if conditions warrant, the system deploys the tire chains. This process is swift, taking only seconds to complete. Once the road conditions improve, the driver can again activate the Switch to retract the chains.
The automatic function simplifies the process, allowing drivers to focus on maneuvering their vehicle without manually handling heavy chains. This technology is particularly valuable for commercial vehicles that frequently encounter adverse weather.
Understanding the functionality of the Switch for On Spot Tire Chains lays the groundwork for exploring additional features and benefits of this innovative system. The next section will delve into how this technology improves safety and efficiency for various types of vehicles in challenging driving conditions.
