AMGO® OH-12S 12,000 lb Two-Post Lift
The AMGO® OH-12S is a 12,000 lb-capacity clear-floor two-post lift, made for heavy lifting under a lower ceiling. It relies on a direct-drive system and four 3-stage arms, with single-point manual release, overhead safety shut-off, automatic arm restraints. Power unit 071102 is crated with each lift.
Lower height settings (143 1/8"-167 1/8") let the OH-12S fit garages that can't clear a full-height 12,000 lb lift while keeping an open floor.
Who It's Built For
- Low-clearance garages that still need heavy-duty capacity
- Heavier vehicles where garage headroom is limited
- Shops fitting real capacity under a modest ceiling
- Garages trading a bit of height range for lower overall height
- Home-and-commercial hybrids with lower ceilings
What It's NOT Built For
- Anything over the stamped capacity figure
- Any in-ground mounting scheme
- Thin garage slabs that need an upgrade first
- Two-wheel and quad service
- Tire bays with no lifting requirement
Key Differentiator: Heavy-capacity open floor
Lower height settings (143 1/8"-167 1/8") let the OH-12S fit garages that can't clear a full-height 12,000 lb lift while keeping an open floor.
- Heavy lifting under a low garage ceiling
- Shops that need full standard lifting height
