5) Determine the sheave location on the bracket
based on Column Extension Height, see Fig 2.
Note: The column has been assembled with
the sheave in the highest position on the
bracket for the lift installed at STD (max)
height.
Reposition the sheave to the middle hole
for -6” install height and to the bottom position for
-12” install height.

6) Remove the bolt, sheave pin, sheave, spacer, and
bushing,
Fig. 2
, to allow the cable to be installed.
7) Route a cable through a carriage and out the
bottom. Route it back up and into the inside hole
at the top of the carriage, see Fig 2.
Ensure
cables do not twist or wrap around hoses
during routing
.
8) Place the 1/8” spacer inside the bracket centered
over the bracket hole based on the chosen install
height. Install the cable on the sheave and slide
into place. Stack the 3/8” spacer onto the sheave
assembly. Still holding the sheave assembly, slide
the pin into place. Install the bolt to secure the pin,
see
Fig 2
.
9) Pull tension on the free end of the cable and
ensure proper routing. While pulling tension on
the cable, slide the cylinder and carriage down
until the carriage is 8” from the baseplate. Slide
the hydraulic cylinder down and route the
hydraulic hose around the base tabs to prevent
rotation of the cylinder. While pulling tension on
the cable to avoid kinking, slide the carriage and
cylinder down to base of lift.
10) Assemble column extension to column by lining
up the correct set of holes and using the 1/2”-13 x
1" lg. hex flange head bolts,
Fig. 3.
Note: the
column extensions are adjustable by 6” and
12”.
11) Repeat the cable routing / lower sheave install
and the column extension install for the other
column.
12) Erect and align both column assemblies.
