Direct Lift HR8000 - Manual (Page 10)

TWO COLUMN 8K FLOOR PLATE LIFT CO7589 IN50014 Rev. D 03/2/2010 10
STEP 8: Use the existing holes in column base plate as a guide for drilling the 3/4” diameter
holes into the concrete. Drill the anchor holes only for ONE column, installing anchors as you go.
You will install anchors in second column after the cables, hoses, and floorplate are installed.
NOTE:
Drilling thru concrete slab (recommended) will allow the anchor to be driven thru the
bottom of slab, if the threads are damaged or if the lift will need to be relocated.
CAUTION!!
Anchors must be at least 6” from the edge of the slab or any seam.
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 equal to 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.
Place a flat washer and hex nut over threaded end of anchor, leaving approximately 1/2"
of thread exposed carefully tap anchor. 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 concrete (28-day cure). If the
concrete is very hard only one or two turns may be required. Check each anchor bolt
with torque wrench set to 85 foot pounds.
