New Sliding Barrier-Lip Series by NORDOCK

NORDOCK has a new powerful Hydraulic Leveler with a Safety Sliding Barrier-Lip. The SLIDING BARRIER-LIP with its patent pending design is a hydraulic dock leveler that provides strength, reliability, and increased safety thanks to its automatic positioning sliding barrier-lip that prevents accidental falls off vacant docks. The BARRIER™ SERIES SBL model features full hydraulic powered deck and lip functions controlled by a single push button for easy-to-use operation. The barrier-lip in the stored position is designed to withstand a 10,000 lb., 4 mph forklift impact without failure.

Available in 30,000, 40,000 or 50,000 lb. capacities and standard nominal sizes of 6′ wide x 6′ long to 7′ wide x 10′ long. Standard features include full operating range telescoping side guards, fall protection velocity fuse and a comprehensive warranty.


The operator presses the ‘raise’ button until the deck is fully raised and lip automatically extends, or is independently extended by pushing the lip extend control. On releasing the button, the extended lip will descend onto the truck bed. The standard 20″ long lip projects 15″ beyond a 4″ bumper to engage a truck bed 8″ above or 12″ below floor level.

Emergency latching stop button provided to arrest deck movement when pressed. To store the leveler, the operator presses the control button until the lip fully retracts. Releasing the button lowers the deck into its stored position, automatically providing the 6″ run off barrier.


The platform is a unitized welded structure with continuous welds at the beams; header plate and lugs for maximum strength. The deck and lip plates are constructed of minimum 55,000 PSI yield material and the beams are 6″ formed or structural channels with welded side guards to provide additional platform strength.

The continuous rear hinge provides 4″ of side-to-side tilt with no pinch point and the frame has six solid steel rear supports and an open design for easy pit cleaning. Lip supports prevent illegal entry when the door is closed. Front and rear hinge rods are SAE 1045 material, zinc plated and factory coated with anti-seize lubricant.
