Thanks for the video, never heard of them before.

These are the ones used the most in the US. Most fire trucks, school buses, ambulances, oil and propane trucks, and many highway trucks have them now here in New England. They are driven by a little wheel that gets pushed against the truck tire by an air cylinder when activated. They work pretty good although not quite as well as actual tire chains but can get you out of bad situations and are activated on the fly by a switch in the cab.

Chains are an amazing thing. If you want to see off road capable put 4 chains on a 4wd pickup

Once you watched a skidder work you you'll keep your pickup on the road.

My '84 chevy is chained on all four corners. It will really push some snow. My driveways are hilly, unpaved, and tend to ice up. The truck won't wash out when backing across an angle.
