10) Position runways on blocking
(see Fig 9)
per
layout lines established in step 1. Use four 30”
long 4x4’s spanning the width of the runway
and four 12” long 1x4’s to shim up the jack-rail
side of the runway. Cable #1 & #2 should be
extending out from the front of the power
runway and cable #3 & #4 from the rear of the
power runway,
Fig 9
.
11) Position the front and rear cross beams,
Fig 8
.

Runway Layout
12) Remove the four (4) cross beam sheaves
(one sheave from each end). The runway
sheave pins do not need to be removed.
13) Starting from the bottom of the left sheave
stack, route cable #4 through the access hole
and up out the left end of the rear cross
beam, repeat for cable #2 running the length
of the power runway and out the right end of
the front cross beam.
14) Starting from the top of the right sheave
stack, cable #3 runs the length of the power
runway and out the left front side of the cross
beam, repeat for cable #1 that will come out
the right rear cross beam.
15) Look through the power end of the cross
beam and ensure that cables have not
crossed.
16) Reinstall the cross beam sheaves with one
plastic bearing washer and spacer on each
side of each sheave.
17) Secure the cables to the top of the column
with the nut and jam nut provided,
Fig 10
.

18) Assembly the hydraulic bulk head fittings and
attach the hose from the under side of the of
power runway to the fittings.
19) With runways and cross beams loose, attach
the mechanical lock bar to both cross beams
with the supplied hardware. Tighten once
cross beams are attached to the runways.
20) Attach both cross beams to the runways with
M12 x 35mm lg. bolts, lock washers and
washers (two at each end of each runway).
Do not torque bolts yet.
21) Check the layout of the lift in the bay. If
anchoring the lift, this is the last chance to
make adjustments. Adjust the position of the
runways so the distance from power side
jack rail to idler side jack rail is the same at
the front and the rear and the diagonal
measurements from the front tip of one rail to
rear tip of the opposite rail are within 1/4”,
Fig 11.

Final Runway Positioning
22) Center cross beam bolts with slots in runway
and tighten. (Be careful not to move
runways.)
