direction requiring a left and right side wheel. When operated in reverse, less traction is provided because the chain will want to roll.

Automatic tire chains / automatic snow chains - 6 Chain System
Automatic tire chains are air operated by a dash-mounted switch that controls an electrically actuated air valve. When actuated, air flows to air cylinders mounted to the vehicle axle. An arm pushes out from the air cylinder pressing a wheel with strands of hardened chain against the inside of the drive axle(s) tires causing the chain wheel to rotate sending the chains under the tires.
The automatic ice and snow chain apparatus is installed on a single or tandem axle vehicle. The chains can be installed to the front or the rear of the axle via a special mounting bracket. When engaged, two pneumatic air cylinders depress a set of chain wheels down against the tire into the engaged position. Each wheel has either six or twelve chain strands that are each attached to the wheel by a series of six interlocking plates, bolts, washers, and locknuts.
When engaged, the chain wheels contact the inside of the vehicle tires at the center point of the tire approximately 3" to 4" above the ground. The vehicle tires spin, which turns the chain wheels. The spinning of the chain wheels cause the chains to be centrifugally thrown into the "V" formed between the tire and the road in the front or in the rear of the tires, depending on whether the vehicle is going forward or backwards. The automatic ice chains increase traction on ice or packed snow.
When disengaged, a spring inside the air cylinder retracts the chain wheel into the stored position under the chassis. The automatic tire chain unit includes one complete set of tire chains for one axle. (2 tires)
Automatic snow chain system operates in forward or reverse.
Automatic Tire Chains Air System Explanation.
Two air chambers are made of aluminum approximately 5" in diameter; with a 6 mm wall thickness. The air cylinder lid has a recessed area for the diaphragm which fits tightly over the upper lip of the air cylinder housing for a maximum seal. Each chamber is capable of holding 62.5 cubic inches, resulting in a total of 125 cubic inches of air per application. This is roughly 4 percent of a typical 12 CFM engine-driven air compressor in a very brief period. The air is supplied by the vehicles air system or an electric 12 volt air compressor and an air reservoir tank 1100 cubic inch (see Aux. Air System).
If your vehicle does not have air brakes or onboard air, the auxiliary air system will be required for using the automatic tire chain system.

|FAQ's||Insta-Chain Automatic Tire Chains Ferquesntly Asked Questions
Automatic snow chains or tire chains are alternative traction devices (ATDs). Alternative because they are an alternative to conventional tire chains, but unlike conventional chains they do not require the driver to exit the vehicle to use them.
Insta-Chain offers three models of automatic tire chains, the standard 6-strand model as well as 12, and 18 strand versions. The 12-strand model provides twice the traction at minimum speed of only 3-3.5 mph. All 6-strand models require a minimum speed of 5-6mph. The 18-strand version also gives traction at speeds as low as 3 mph.
Yes! Insta-Chain Automatic Snow Chains use a specially designed square straight-linked chain so your INSTA-CHAINs will supply superior traction in both forward and reverse directions.
The chain wheels are comprised of six patented, interlocking chain strand plates that allow you to replace each chain segment individually, if a strand happens to break or
wear out. Therefore, you save money by not paying for an entire chain plate when only one strand needs to be replaced.
As any good mechanic will tell you, grease-able bearings have proved their superiority over the years. The wheels and arms work in very harsh environments. They run in water, snow, ice, salt, chemicals, and road debris. By utilizing grease-able bearings, rather than the sealed bearings, your Insta-Chains will last much longer than non-grease-able bearings.
The chains will last much longer than any standard ladder chains because they are used only when needed on ice or snow. Chain wears out when it touches bare pavement. The Insta-Chains are engaged and disengaged as needed so as to prolong the life of the chain. Insta-Chain also uses carbon manganese hardened alloy steel for maximum wear and durability.
Yes, Insta-Chain Automatic Tire Chains are DOT accepted for use in every state with chain laws.
Like regular ladder chains, you should not exceed a speed of 30 mph while the Insta-Chains are engaged. The Insta-Chains may be engaged up to 25 mph, and can be disengaged at any time or speed. Insta-Chains work best when engaged while moving, before slippage
occurs. You can engage the chains from a stand still by spinning the wheels at least 5 mph and then engaging the INSTA-CHAINs.
INSTA-CHAINs are mounted by attaching the chain unit to the Ubolts on the vehicles suspension with a universal that will fit most vehicles, or with a custom bracket that is specifically designed for your vehicle. You can install the chains yourself by following the instructions or you can have your local INSTA-CHAIN dealer do the installation. No person who is not specifically qualified for suspension work, suspension modification, or suspension repair should attempt installation.
The Insta-Chains are effective in snow up to 5-6 depending on the type of snow. If it is powdery snow then the chains can pass through it easier. If it is a wet slushy snow, the chain may become inhibited at deeper snow depths.
Probably not. The chains typically all wear together. So, if you break one, the chances are that you will not have to replace another for sometime.
No! This is a common myth in the industry. The Insta-Chain wheel works at a relatively low rpm. The amount of chain mass between a new and used chain link is relatively small. This difference will not throw off the functionality of the chains wheels.
The Dust Boot protects the Air Cylinder from clogging up with dirt, rocks, pebbles, sand, and other road debris. It keeps the Air Cylinder moving freely.
Most likely, yes. Insta-Chain fits the widest variety of vehicles and suspensions on the road ranging from 1/2 Ton through Class 8. Vehicles with Hydraulic Brakes may require the addition of an Auxiliary Air Compressor.
