Abstract
A snow chain system that attaches to the frame of a semi-truck and/or trailer, or a large commercial construction vehicle. The system includes a removable chain box, a chain barrel, a chain spreader, flashlight driver notification, a drag brake, a box swivel, and tire clamp. The snow chain is rolled out of the chain box directly onto a tire tightly with minimal human involvement. It provides for installed a tight snow chain onto the tire when rollout of the snow chain to the tire is completed. After snow chain use, it rolls up manually back into the chain box and is ready for immediate service should another need arise. All necessary equipment is organized, helping the driver with safety concerns.
