To minimize back injuries from jolts that lift truck drivers experience when crossing the leveler platform and warehouse floor as semi-trailer trucks are serviced, smooth-transition technology has been added to a line of high-capacity loading dock levelers. The RHH-5000 and RHJ-5000 jumbo levelers handle loads from 25,000 to 40,000 pounds. The levelers include a constant radius rear hinge to reduce bumps and gaps between the leveler and warehouse floor, and a two-point crown control on the leveler’s front lip for seamless crossing to the truck bed. The smooth pathway improves productivity by allowing lift truck drivers to maintain safe speeds as they travel across the leveler. Rite-Hite, 800-456-0600, www.ritehite.com.
