MILWAUKEE, Wis. - Rite-Hite Corporation’s line of loading dock levelers is specifically designed to minimize the potential for chronic personal injuries at the loading dock resulting from dock shock. The line of hydraulic, air-powered and mechanical levelers is also engineered to improve dock productivity and reduce dock equipment lifetime ownership costs. Rite-Hite coined the term dock shock to describe jarring that occurs when a lift truck (stand-up walkie or forklift) crosses between the warehouse floor and the trailer bed due to the bumps and gaps that exist on traditional dock levelers. Dock shock is a source of vibration, which is known to pose a serious health safety risk. Whole Body Vibration (WBV) and intermittent vibration are growing concerns worldwide.
