10. SUGGESTED MINIMUM INSPECTION REPORT
Mobilift AX / AXR Wheelchair Lift, (Minimum inspection once per year)
1. Perform a complete general visual inspection for loose fasteners and for damaged or missing components.
2. With the deck at ground level, a 10 lb. (5 kg) pull on the middle of each of the outer lifting cables should separate the cables between 3-1/4 and 3-3/4 inches (8
and 10 cm) for the AX and between 3-3/4 and 4-1/4 inches (9 to 11 cm) for the AXR.
3. Check the full visible length of each lifting cable with the deck at ground level and at two feet from ground level for corrosion or fraying, with particular attention
to the point at which the cables turn in under the deck.
4. With the lift deck about half way up with no load, measure the distance from the deck to the top of the main frame at each corner. The two rear measurements
(near the ground ramp) should be within 1/2 inches (1 cm). The two front measurements (near the bridge ramp) should also be within 1/2 inches (1 cm). The front
should be 1
±
1/4 inches (2 to 3 cm) higher than the rear.
5. Check by looking under the shroud that the cables are in their grooves on the winding drum. Crank deck to full height with no deck load and recheck the cables
on the winding drum.
6. Visually inspect all threaded cable anchors (35 in total) to ensure they are secure and have properly installed lock nuts:
Frame and Wheel Anchor Points:
Outrigger Cables (4)
Wheel Activation Cables (located underneath the wheel crank side wheel bracket) (3)
Tow bar/Brake Handle Activation Cables (4)
Main Deck Paralleling Cables (4)
Under Main Deck Anchor Points:
Lifting Cables (4)
Return Cables (2)
“Z” Cables (which support the Bridge Ramp when extended) (2)
Bridge Ramp Centering Cables (there are 2 cables with a total of 4 threaded anchors)
Main Deck Anchor Points:
Bridge Ramp Drive Cables (2)
Chair Deck Bracing Cables (6)
7. Where possible, inspect all the non-threaded anchors for the cables listed above.
8. Check that the paralleling cables are on all four pulleys, are not frayed, and have no slack.
9. With the deck all the way down, a pull of 10lb at the mid-point of each paralleling cable should produce the following deflections for an AX lift : 1 to 1-1/2”
inches (2.5 to 4 cm) for the cables on the left (drive side) of the lift, and 1/2 to 1 inches (1 to 2.5 cm) for cables on the right (counterbalance side) of the lift. On an
AXR the deflections should be 1-1/2 to 2-1/4” (4 to 6 cm) for the left cables and 3/4 to 1-1/2” (2 to 4 cm) for the right cables.
10. Check that the paralleling cable pulleys can not scrape on the sides of the posts.
11. With the deck at ground height, check that the counter balance cable is under tension and shows no signs of fraying or damage. Repeat this test with the deck at
full height.
12. Check that the lifting crank handle and bridge ramp extension handles lock automatically when released.
13. Crank the deck to full height and back down with 400 to 500 lb. (180 to 230 kg) (three people) on the deck (a full up down cycle should take no more than one to
two minutes).
14. With the above weight on the deck and the deck approximately 36 inches (90 cm) off the ground, using a spring scale or weight, check the force on the crank
handle, the force cranking up should be between 15 and 20 lb. (7 and 9 kg). The force to crank down should be between 1/3 and 1/2 of the force to crank up.
15. Did the deck crank smoothly up and down? (On the down movement it is normal to have a slight squeal or chatter from the brakes as with automobile brakes).
16. Inspect the tires, including the spare, for damage or wear. They should have between 28 and 32 p.s.i. (190 and 220 kPa) pressure at 70
°
F (20
°
C).
17. Crank the wheels down to raise the lift off the ground. Check for full movement and smooth operation of the wheel crank mechanism.
18. With the wheels in the full down position, measure the distance from the ground to the frame next to the wheel axle on each side of the lift. These two
measurements should be within 1/2 of an inch (1.25 cm) of each other.
19. Check the action of the front and rear idler wheels. With the main travel wheels cranked fully down, the rear idler caster should be in a position to hold the lift
essentially horizontal with no part of the frame contacting the ground. The front idler wheel should prevent the frame from contacting the ground when the lift is
tipped forward, but should normally be 1/2 to 1 inch (1 to 2.5 cm) above ground height.
20. With the lift in the "travel" mode, check that the lift rolls easily with push handles down and that it stops immediately when these are released. Check that the lift
rolls easily with the tow bar pulled down to 45
°
and that the lift stops when the tow bar is released.
21. Check the action of the left and right outrigger pairs. The outriggers on each side should extend and retract to their limits smoothly and in unison.

22. Check that the outrigger latches function properly.
