INsTALLATION
8. Bolt the clevis bracket (with the two bolts provided)
to the flat base plate using the third and fifth
threaded holes. The holes referred to are counted
from the rear of the leveler.
9. If the gap between the side of the clevis bracket and
the side of the deck support channel is less than
6¼", you will not have enough clearance for the
cylinder pin. It will be necessary to install the ramp
cylinder into the clevis bracket before the clevis
bracket is bolted to the base plate.
10. Once bolted in place, weld the clevis bracket to
the base plate. The weld must be continuous and
surround the entire perimeter of the clevis bracket.
See Figure 11.
PIT FLOOR BRACKET INsTALLATION
1. Attach main lifting cylinder to the ramp bracket with
the hose port upward towards the ramp.
2. Attach the clevis pit floor bracket assembly to the
cylinder rod with the hardware provided.
3. Full extend the cylinder rod and allow the clevis pit
floor bracket to lie flat on the pit floor. Mark the
location where the bracket makes contact with the
pit floor is the pit floor bracket mounting location.
4. Temporarily secure the pit floor bracket in place.
5. With a hoist, lower the ramp slowly to make sure the
cylinder will not bottom out at the full below dock
position. Adjust the pit floor bracket if needed.
6. Disassemble the pit floor clevis from the baseplate
by unscrewing the (2) bolts.
7. Place the baseplate in the marked off area.
Securely fasten the baseplate to the pit floor using
the (6) ¾" x 6" concrete anchors provided.
8. Reassemble the pit floor clevis to the baseplate,
using the (2) bolts from Step 6.
9. Weld the clevis to the baseplate. The weld must be
continuous and surround the entire perimeter of the
clevis bracket. See Figure 13.
Always disconnect main power before doing any
welding. Always attach ground lug to the part
being welded.
Main lifting cylinder will be installed with the rod
end down.
