Lift

2 min read

Spec

“Please pour the entire 3rd bay slab at 6″ thick, 4,000 PSI with rebar reinforcement. In the area where a future 2-post lift will be installed, leave two 4′ × 4′ PEX-free zones (no tubing) where the lift columns will be located. Keep tubing at least 12″ clear around those zones. Provide a sketch of the tubing layout and photos before pouring.”

Notes

  • Prefer 12k lbs 2-post lift for safety margin.
  • Candidate: BendPak GrandPrix GP-9LC (link in meeting notes).

Ceiling, Brands, and Slab Integration

  • 10’ ceiling implies short-column lifts (~9k–10k lbs). Full raise height may be limited for taller vehicles (e.g., Sequoia).
  • Corvette side pipes may need low-profile arms/ramps.
  • Brand/model short list: BendPak XPR-9S-LP / GP-9LC, Atlas BP8000, Rotary SPOA10 short-column, Forward I10 short-column, Challenger CLFP9, Halo HL2-10K.
  • Slab baseline to cover most models: 6” slab, rebar grid, 4000 PSI (some mfrs recommend 4500–5000 PSI; confirm with concrete contractor and selected lift manual).
  • PEX coordination: two 4’×4’ PEX-free column pads with 12” buffer; photo and sketch documentation before pour.

Actions

  • Confirm column center spacing (typically ~10’6”–11’) and mark PEX exclusion pads accordingly. — stage:: 2
  • Provide slab spec to concrete crew and verify PSI requirement per chosen lift. — stage:: 2
  • Capture photos/sketch of PEX layout prior to pour. — stage:: 2
  • Finalize lift model post-build; verify anchor pattern and torque spec. — stage:: 6
