Utility vehicles: Automatic Tire Chain System

utility vehicles Onspot

Safety products: The Onspot Automatic Tire Chain System offers the traction of a single set of conventional snow chains at the flip of the dashboard switch without having to stop the vehicle. The system works in forward, reverse or while braking in either direction.

An electric switch mounted in the cab energizes an electric solenoid air valve conveniently mounted within the vehicle. The air supply to the solenoid can be obtained from either the vehicle’s onboard air system or our 12-volt air compressor kit.

When the dashboard switch is activated, compressed air enters the cylinder which lowers the chainwheel position to contact the inside of the tire. The contact between the sidewall and the rubber-covered chainwheel causes it to rotate, creating enough centrifugal force to swing the chains out and underneath the tire.

Six lengths of chain spaced at 60-degree intervals on the chainwheel ensure that there are always 2 chain strands between the tire and road surface. Onspot works when you are accelerating, braking, or are in a wheel lockup condition. The chains may be engaged in forward or reverse.

When you are ready to turn off the chains simply flip the switch to the off position. The supplied air exhausts from the system allowing the chainwheels to return to their resting position, safely away from the road and other potential hazards.

Built-In Reliability
Onspot, the originator of the automatic tire chain system, has built a solid reputation
due to its successful research and design for nearly four decades. The Onspot system is built to absorb shock and to withstand the hostile environment found underneath the truck chassis. The system utilizes chain made of special through-hardened alloys which have been proven to stand the test of time.

Short or Long Runs
Often drivers think that the Onspot automatic tire chain system, which works whether you’re in forward or reverse, is for use only when encountering patches of ice or snow. The Onspot system can be engaged on the go and is meant to withstand use for the long hauls at speeds of up to 35 MPH.

Safely and Quickly
Onspot is the solution of choice when deadlines must be met or in situations where passenger safety is paramount. Once your vehicle is equipped with Onspot, the system can be engaged in a matter of seconds. All it takes is a flip of the switch located within the cab of your vehicle. If black ice or packed snow lies ahead, you’ll have the additional safety advantage of knowing that you can immediately deploy your Onspot system. Forget the days of pulling to the side of the road and putting yourself at risk to manually install tire chains. The safety and convenience of Onspot is available anytime you need
extra traction.

Fits Most Vehicles
A variety of Onspot models are available for either spring or air-suspended vehicles. The system is adaptable to most trucks and buses. Onspot fits each vehicle individually, thereby eliminating the problems inherent in universal adapters. Onspot helps choose the model best suited for your operating needs. Each system is delivered with an adapter kit, designed to fit your specific vehicle at our manufacturing facility.

Precise Installation
A properly installed Automatic Tire Chain system is the basis of effective operation.
It is best when a trained Onspot professional, equipped with knowledge and experience, handles your installation. Call your nearest Onspot representative or dealer to assist you with your installation needs.

Save Time and Money
Onspot is designed to last the service life of the vehicle with minimal maintenance required. Often it can be transferred to a replacement vehicle. The Onspot system is both efficient and cost effective, saving time and money.
