When dock space is limited or the working range of a full size, pit-style leveler is not needed; NOVA’s edge-of-dock levelers are an economical option. Edge-of-dock levelers mount to the dock face and provide a working range of 5-inches above and 5-inches below the dock.

OPERATION
The dock attendant pulls the release chain which releases the holdown and allows the leveler to rise and the lip to extend. The attendant then walks onto the leveler to lower the leveler and lip to the bed of the truck or trailer. Contact between the leveler lip and the truck or trailer bed is maintained throughout the loading/unloading process by the holdown. If below dock operation is required, the front pull chain is pulled which retracts the safety legs and the leveler will lower to the desired position when walking down the leveler. When loading or unloading is complete, the release chain is pulled to raise the leveler and lip off the bed of the truck or trailer. Once the lip has fallen pendant, the attendant walks onto the
leveler to lower it to the stored position.
STRUCTURAL
The platform is constructed of 1/4-inch thick four-way high tensile 50,000 minimum yield A572 safety tread plate.The platform is reinforced and supported by full-length 6-inch high formed C channels for 25,000-pound Comparative Industry Rating (CIR) capacity to 40,000-pound CIR units, full length
6-inch high structural channel for 45,000-pound CIR units and full-length 6-inch high structural channel and I-beams for 55,000-pound CIR units.
The supports are welded to the deck, front and rear headers for full structural support. The front and rear header plates are 1/2-inch thick x 7-inch high hot rolled steel. NOVA NMS series lips have a four-way safety tread plate, the 25,000-pound CIR is 1/2-inch thick, and the 30,000, 35,000, 40,000, 45,000
and 55,000-pound CIR are 5/8-inch thick. The standard lip length is 16 inches on all capacities. Hinge tubes have a 1 3/4-inch outside diameter (OD) × 5/16-inch wall, 1 7/8-inch OD × 3/8-inch wall or 2 1/8-inch OD × 1/2-inch wall depending on CIR. All lip hinge pins are M1044 steel 1-inch in diameter. Steel header gussets are standard on all models 35,000-pound CIR and above. All units have grease fittings
as standard. All platforms are designed to compensate for up to 4-inches of the canted trailer bed
INSTALLATION METHOD
- For new construction, a flush or recessed 8 to 12-inch embed channel is the standard requirement and strongly recommended; the unit is then welded to the embed channel in the foundation wall
- For existing docks without a preferred embed channel, but with an angle embedded at the front edge of the dock, the EOD is welded across the top angle and anchored to the face of the dock, or an optional approach ramp can be added on the dock floor for additional strength
- For docks with no steel embed material of any kind, a formed angle, or independent approach, faceplates are available to maximize the strength of installation
BUMPERS AND BLOCKOUTS
- Properly designed dock bumpers help protect the deck plate and building from the approaching truck
- Constructed of formed steel and incorporate a full height internal gusset for extra support
- Feature 4-inch thick reinforced rubber molded bumpers
- Every leveler is shipped standard with 12 x 13-inch heavy-duty bumper blocks
