With technology always advancing, it is no wonder that
automatic tire chains have made their way into the tire chain market. These
tire chains take away the pain of attaching tire chains in wintry or wet
conditions, and can save drivers a lot of time.
Automatic tire chains can be used on pickup trucks, RVs,
mobile homes, Trucks, and buses, and they offer the
traction of a single set of conventional snow chains at the touch of the
button, which means an end to stopping and getting out of the vehicle.
To install automatic tire chains, drivers mount an electric
switch to their dashboard, which provides 12 volts to an air solenoid mounted
on the vehicle's frame rail. Compressed air is then supplied from either the
vehicle's onboard air system or a 12-volt compressor kit. When the dashboard
switch is activated, the solenoid opens, thus allowing compressed air to enter
the air cylinder and lower the chain wheel so that it contacts the inside of
the tire. The friction between the tire and the rubber-covered chain wheel then
causes the chain wheel to rotate, which creates enough centrifugal force to
wave the chains out in front of the tire.
Chain is spaced at 60-degree
intervals in sixth lengths on the chain wheel. This guarantees that there are
always two chains between the tire and the road service, regardless of whether
the driver is accelerating or decelerating. The traction is obtained both in
forward and reverse. When the dashboard switch is turned off, the solenoid
exhausts the air, and the chain wheels are brought back to their resting
position.
Automatic tire chains are a great new technology for anyone
who wants tire chains -- but does not want the inconvenience of getting out of their
car and installing the chains in adverse weather conditions.
