Abstract
A commercial chain block system is disclosed herein including a block assembly including an elongated platform supported by a first-support-leg, and a second-support-leg extending lengthwise along opposing sides of the platform. The first-support-leg and the second-support-leg have a ramp at one end forming a 45 degree angle. The platform, the first-support-leg, and the second-support-leg are configured to support a tire of a vehicle upon a top-surface of the platform and assist in installing chains on tires of commercial vehicles.
