OPERATION

The push-button is depressed and held allowing the electric blower to fill the air bladder which raises the platform. When the fully yieldable lip extends at the top of the cycle the button is released allowing the extended lip and platform to lower onto the trailer bed. Upon trailer departure, the lip can be retracted and the unit restored to a safe cross-traffic position. In-use and stored positions are achieved without manual operation. Operable range is 12-inches above/below dock level. Platform is allowed to automatically float up and down with trailer movement.

STRUCTURAL

The platform is constructed of 1/4-inch thick four-way high tensile 50,000 minimum yield A572 safety tread plate. Platforms are 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 height structural channel for 45,000-pound CIR units and full length 6-inches high structural channel and I-beams for 55,000-pound CIR units, all welded to the deck for firm structural support.

Front and rear header plates are 1/2-inch thick × 7-inch high hot-rolled steel. NOVA’s NAS series lips are four-way safety tread plates, 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 are 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 1-inch diameter M1044 steel. Steel header gussets are standard on all models with 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 canted trailer bed.
