The Smooth Transition Dok System addresses two critical issues at the loading dock that contribute to worker injuries and product and equipment damage: Dock Shock and Trailer Drop.
Dock Shock Solution: Smooth Transition Dock Levelers
• Constant-radius rear hinge design reduces the bumps and gaps
• Two-point crown control on the front lip hinge distributes the load evenly, smoothes out the transition between the leveler and the trailer bed, and extends the hinge life
• Extended lip chamfer provides a smooth transition from the trailer bed onto the leveler
• New Smooth Transition leveler design reduces Dock Shockup to 76 percent!
Trailer Drop Solution: STR-4100 Dok-Lok Vehicle Restraint
