⚠ WARNING Cutting through a tensioned cable can result in injury or death. Do not drill into a
post-tension slab unless the building architect confirms you are
not going to hit a
tensioned cable or you have located it using ground penetrating radar.
If colored
sheath comes up during drilling, stop drilling immediately
.
⚠ WARNING Your Concrete and Anchor Bolts must meet these specifications. Only install your
Lift on a Concrete surface. If you install a Lift on asphalt or any other surface, or
your Concrete or Anchor Bolts do not meet these specifications, it could lead to
product damage, Vehicle damage, personal injury, or even loss of life.
Dannmar Lifts are supplied with installation instructions and concrete fasteners meeting the criteria as
prescribed by the American National Standard “Automotive Lifts – Safety Requirements for
Construction, Testing, and Validation” ANSI/ALI ALCTV.
⚠ WARNING Use only the Anchor Bolts that came with your Lift. If you use components from a
different source, you void your warranty and compromise the safety of everyone
who installs or operates the Lift.
Lift buyers are responsible for conforming to all regional, structural, and seismic anchoring
requirements specified by any other agencies and/or codes, such as the Uniform Building Code and/or
International Building Code.
To anchor the Posts:
1. Locate the hardware you will need: four Anchor Bolts, four Nuts, and four washers
per Post .
2. Using the Base Plates as guides, drill 4 inch deep holes for the Anchor Bolts—one hole in each
corner of the Base Plate, so four holes total per Base Plate.
Go in straight, in the center of the hole; do not let the drill
wobble.
Use a carbide bit (conforming to ANSI B212.15).
The diameter of the drill bit
must be the same as the
diameter of the Anchor Bolt. So if you are using a ¾ inch
diameter Anchor Bolt, for example, use a ¾ inch diameter
drill bit.
