WARNING
VERTICAL CLEARANCE
Check the height of the area where the lift is to be
installed. Clearance should be calculated based on
the full raised height of the lift.
Failure by purchaser to
provide adequate clearance
could result in unsatisfactory
lift performance, property damage, or personal
injury.
FLOORING
Be certain the concrete floor can properly handle the
loaded lift. Floor should be in generally good
condition with no large cracks, spalling or
deterioration.
Minimum requirements for concrete are 4 inches
minimum depth, with steel reinforcement, 3500
psi, cured for 28 days per local commercial
practice. Floor should be level within 3/8 inch over
the installation area. No anchors should be installed
within 8 inches of any crack, edge, or expansion
joint. If these conditions cannot be met, a pad may
be poured to accommodate the lift.
Check with local building inspectors and/or permits
office for any special instructions or approvals
required for your installation.
A qualified person should be consulted to address
seismic loads and other local or state requirements.
Failure by purchaser to
provide the recommended
mounting surface could result
in unsatisfactory lift performance, property
damage, or personal injury.
LOCATION
This lift has been evaluated for indoor use only with
an operating ambient temp. range of 5 – 40°C (41–
104°F). Outdoor installation is prohibited.

LAYOUT
Note:
This lift can be installed at three different
heights and three different widths. The Cable
adjustment for the Height variation will be
accommodated by the Lower Sheave Bracket.
The Cable adjustment for the Width variation
will be accommodated by the take-up tube in
later steps.
The height and width must be established
before beginning, as this will determine the
lower sheave position and cable take up tubes
to be used.
1) Once the lift location has been established,
ensure that the vertical clearance and flooring
requirements have been met per page 3.
2) See Fig 1 for the lift layout. Determine which
side of the bay that the power unit will be on and
identify the column assembly with the power unit
bracket. Layout the service bay according to the
architect’s plans or owner’s instructions (see Fig.
1b). Failure to install in this orientation can
result in personal and property damage. Be
certain that the proper conditions exist, see pg 3.
LIFT PREPARATION
3) With column assemblies lying flat, remove cable
and hose rolls from inside the column.
4) Manually push carriages up enough to unhook
the cylinder hose from the base plate tabs.
Proceed with pushing the cylinder and carriage
up enough to access all three sheave locations
on the sheave bracket, see Fig 2.

Model CL16
Installation, Operation and Maintenance
Page 5
Rev. 08/24/2021
CL16-IOM-A.doc
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.

BASE PLATE
Fig. 2 – Cable Routing
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.

LOCK RELEASE/PAWL
Fig. 4 – Locking Pawl Assembly
13) Install the locking pawl, actuator, and spring
(Fig. 4). Adjust air cylinder clevis to retract lock
against inside of back of column when air
cylinder is fully extended. Tighten air cylinder
clevis jam nut against clevis.
ANCHORING
Note:
The anchor bolts must be installed at least 8” from
any crack, edge, or expansion joint. Recheck the
area around both base plates.
Use a concrete hammer drill with a 3/4 inch
carbide bit. Tip diameter should conform to ANSI
Standard B94.12-1977 (.775 to .787). Do not use
excessively worn bits or bits, which have been
incorrectly sharpened. A core bit may be
necessary if an obstruction is encountered. Never
substitute with shorter anchor.
14) Recheck “Inside of Columns” dimension (Fig. 1).
15) Using the base plate as a template, drill one
anchor hole. Drill through the floor if possible or
to a depth of 5 inches minimum.
16) Clean the hole inside and out.
17) Assemble a washer and nut to the anchor with
nut just below impact section of bolt. Drive the
anchor into the hole until the nut is 3/4” above
the baseplate (leaving room for shims).
Complete steps 15 thru 17 for the seven (7)
exposed anchors (one at a time) around each
column.
18) Raise both carriages (400 lbs. ea.) high enough
to drill the two inner anchor holes on each
column. Measure both carriage heights to ensure
they are in the same lock position.
19) IMPORTANT:Place a safety support inside each
column as a backup to the locks, since the
hydraulic cylinders are no longer engaged with
the carriages.
20) Repeat steps 15 thru 17 for the two (2) anchors
under each carriage.
21) Shim both columns to plumb using the shims
provided as shown in Fig. 5. DO NOT shim more
than 1/2" at any given point. Use a level no less
than 24” in length to plumb columns.
22) Drive all the anchors until nut and washer
contact baseplate.
Fig. 5 – Column Shimming
23) Tighten Power Column anchors and recheck
column for plumb. Re-shim if necessary. Torque
to 150 foot pounds to set anchors.
24) Loosen Idler Column anchors 1/8” and proceed
with the Overhead Beam installation.
OVERHEAD
25) Before raising overhead into position, install 4 (2
per column) hex flange bolts and nuts in bottom
hole of column extension tab (see Fig. 6
Installation Aid) for temporary support of
overhead. Lift overhead assembly up into
position and install with 8 (4 per column) 1/2-13 x
1” lg hex flange bolts and hex flange nuts per
side as shown in Fig. 6. For the wide position,
the outer overhead holes will be used. For the 6”
reduced width, use one set of outer overheard
holes and one set of inner overhead holes. For
the narrow width, use the inner sets of overhead
holes.

FINAL ADJUSTMENTS
HYDRAULICS
73) Lower the lift to the floor and raise the lift
approximately one foot.
74) Start with Idler side first. Slowly and carefully
loosen the bleed plug on top of the cylinder just
enough to allow the entrapped air to escape.
Repeat for power side.
75) Raise lift 6 inches. Repeat the previous step until
no air comes out of cylinder.
76) Pressure test hydraulic system. Energize power
unit, raise lift to full rise and continue to run
motor for additional 10 seconds. (NOTE:
pressure relief will make a high pitch squeal
sound for these 10 seconds.) Check hydraulic
system for leaks.
77) Energize power unit again for 10 seconds. With
a clean rag, wipe down both cylinder rods. (The
cylinders are shipped with a small amount of
clear anti-corosive lubricant that will be forced
out through the wiper when the lift reaches full
rise.) If lubricant is not wiped clean from the
cylinder rod, the cylinder will apear to be
leaking.
SYNCHRONIZING CABLES
78) Raise lift and ensure carriages lower into same
lock position.
79) Adjust synchronizing cables so the tension is
equal in both cables and carriages are firmly
sitting on locks.
80) Cycle lift to ensure that locks operate
simultaneously. Adjust if necessary.
FINAL CHECKOUT PROCEDURE
81) Demonstrate the operation of the lift to the
owner/operator/employer using a typical vehicle
and review correct and safe lifting procedures
using the Lifting It Right booklet as a guide.
82) Return all provided literature (including this
manual) to the literature pack envelope and
deliver the envelope to the
owner/operator/employer.
