summer 2011 – Entro files for patent protection on innovative new walking system designs

The innovative King-Pin system allows a large sized foot to be placed inside of a confined space but still allow the rig to be moved in any direction. Shawn Smith, Entro’s current president states that “The Future of Rig Walking is Here. These new designs allow rig walkers to be retrofitted to rigs in ways that are more cost effective than ever before.”
