What does dock leveler deck cant mean? Deck cant means that the dock leveler platform can tilt or flex up to 4” per side. If the truck and dock leveler are both level then the deck cant feature is not required. However if the incoming truck is up to 4” higher on one side than the other, this could be caused by an uneven approach, snow/ice build-up on one side of the drive etc. then the deck cant becomes a very important feature. As the dock leveler is cycled the platform lowers to the truck bed and the hinged lip assembly makes contact with the truck bed. Deck cant provides torsional flex allowing the lip to conform or laterally flex to the uneven truck bed. The lip resting flat on the truck bed minimizes and damage to the material handling equipment, product and impact to the operator. Contact your Pentalift Sales Representative for more information.
