OPERATION
The operator presses the control button until the deck is raised and the lip is fully extended. Releasing the button allows the lip to lower onto the truck bed. The operator stores the leveler by pressing the control button until the lip fully retracts. The standard 16″ long lip projects 11″ beyond a 4″ bumper to engage a truck bed 12″ above or below floor level.
ELECTRICAL/HYDRAULICS
The power unit is a frame mounted integral assembly fully tested and oil filled. The 1HP motor is a totally enclosed non-ventilated type available in all voltages. The control box is a NEMA 12 dust tight enclosure with motor starter and single push button. The regenerative hydraulic cylinders are a heavyduty design with polished chrome rods, guide bearings and high-pressure seals. The hydraulic hoses are SAE 100R2 with permanent fittings attached.
CONSTRUCTION
The platform is a unitized welded structure with continuous welds at the beam, header plate and lugs for maximum strength. The deck plate, lip plate, beam sections and lugs are constructed of
minimum 55,000 PSI yield material. A standard center deck beam and welded side guards provide additional deck plate support. The continuous rear hinge provides 4″ of side-to-side tilt with
no pinch point. The frame has seven solid steel rear supports, an open design for easy pit cleaning, and lip supports that prevent illegal entry when the door is closed. The front and rear hinge rods are SAE 1045 superior shaft, zinc plated and factory coated with anti-seize
lubricant.
