3. Installation
3.1 Site Selection
The hydraulic lift is designed only for indoor use Application in a room with explosion hazard is not permitted Setting
in a wet place, a car wash center for instance, is prohibited
3.2 Surface Condition / Foundation & Anchoring
The 2-post hydraulic lift should be installed on level ground The foundation must be 4-1/4” minimum thickness
concrete, with a minimum compressive strength of 3,000 psi Failure to meet the foundation requirement may cause
the lift instability or personal injury Installing on asphalt, soft clay floor or near the expansion gap is prohibited
FOUNDATION and ANCHORING REQUIREMENTS
1. Concrete shall have compression strength of at least 3,000 PSI and a minimum thickness of 4-1/4” in order to
achieve a minimum anchor embedment of 3-1/4”. NOTE: When using the standard supplied 3/4” x 5-1/2” long
anchors, if the top of the anchor exceeds 2-1/4” above the floor grade, you DO NOT have enough embedment.
2. Maintain a 6” minimum distance from any slab edge or seam. Hole to hole spacing should be a minimum 6-1/2”
in any direction. Hole depth should be a minimum of 4-1/4”.
3. DO NOT install on asphalt or other similar unstable surface. Columns are supported only by anchoring to floor.
4. Using the horseshoe shims provided, shim each column base as required until each column is plumb. If one
column has to be elevated to match the plane of the other column, full size base shim plates should be used.
Torque anchors to 130 ft-lbs. Shim thickness MUST NOT exceed 1/2” when using the 5-1/2” long anchors
provided with the lift.
5. If anchors do not tighten to 130 ft-lbs. installation torque, replace the concrete under each column base with a
4’ x 4’ x 6” thick 3,000 PSI minimum concrete pad keyed under and flush with the top of existing floor. Allow
concrete to cure before installing lifts and anchors (typically 2 to 3 weeks).
ANCHORING TIPS
1. Use a concrete hammer drill with a carbide tip, solid drill bit the same diameter as the anchor, 3/4” -
(.775 to .787 inches diameter). Do not use excessively worn bits or bits which have been incorrectly sharpened.
2. Keep the drill in a perpendicular line while drilling.
3. Let the drill do the work. Do not apply excessive pressure. Lift the drill up and down occasionally to remove
residue to reduce binding.
4. Drill the hole to depth of 2” deeper than the length of anchor. NOTE: Drilling thru concrete (recommended) will
allow the anchor to be driven thru the bottom of foundation if the threads are damaged or if the lift will need to be
relocated.
5. For better holding power blow dust from the hole.
6. Place a flat washer and hex nut over threaded end of anchor, leaving the nut almost flush with the top of the
anchor bolt. Carefully tap anchor into hole. Do not damage threads. Tap anchor into the concrete until nut and
flat washer are against base plate. Do not use an impact wrench to tighten! Tighten the nut, two or three turns on
average after the concrete has cured (28-day cure). If the concrete is very hard only one or two turns may be
required.
