New converter dolly makes doubles ‘wiggle free’

wiggleSilver Eagle Manufacturing introduced the latest concept in converter dollies at the American Trucking Associations’ Technology and Maintenance Council annual meeting in Nashville, Tennessee. At a February 15 press conference, the company unveiled its new “T-Dolly.”
