Shops shopping for a 27000 lb 4 post lift for sale are usually stepping up from a 14K or 18K unit because a Class 6 or Class 7 truck, a mid-size RV, a box truck, or a heavy dually just outgrew the old bay. At 27,000 lb capacity a 4-post drive-on is the workhorse for medium-duty commercial vehicles, and picking the right one is more than a spec sheet — runway length, safety-lock design, and slab prep decide whether the lift is a 30-year asset or a headache. We are Automotive Lift Services, based in Ames, Iowa, and we ship, install, and service these lifts across the country.
What a 27,000 lb 4-post is really for
This capacity class sits between the light-commercial 14K and the true heavy-duty 30K-plus machines. It handles Class 5 through Class 7 trucks, cutaway chassis, most RVs on a single-rear-axle chassis, ambulance builds, utility-body service trucks, and shuttle-bus platforms. If your shop sees the occasional loaded Class 8 tractor, this is not the right lift — that job needs a 30K or 40K unit. But for the day-in, day-out mixed fleet garage, a 27000 lb 4 post lift for sale at this tier is the sweet spot for cost versus capability.
Rail length versus short runway
The number one buyer mistake in this class is buying too short. Standard rail lengths run around 18 to 22 feet clear; extended-length options push past 26 feet, which you need for cab-and-chassis service trucks with utility bodies, dually pickups with long-bed conversions, and any RV over 24 feet. If you cannot fit the wheels between the ramps and the runoff stops without hanging axles over the ends, you have loaded the lift wrong. Ask us the exact wheelbase you plan to service and we will size the runway before you commit. Our 4-post lift collection lists rail lengths and drive-through width per model.
Weight distribution and axle limits
Total capacity is only half the story. Every 4-post lift has a per-axle limit, typically a 60/40 or 55/45 front-to-rear split. A 27,000 lb machine is not the same as two 13,500 lb axles — the rear axle is usually capped lower to keep the runway from twisting under an unbalanced load. Loaded service trucks and RVs with rear water or generator boxes can be surprisingly rear-heavy. When you shop a 27000 lb 4 post lift for sale, always check the front-axle and rear-axle sub-limits, not just the sticker capacity, and match them to the heaviest configuration you will actually park on the runway.
Safety-lock design matters at 27K
At this capacity the difference between a mechanical rack-style lock every foot versus an air-released ratchet lock every 3 to 4 inches shows up in real service work. Tighter lock spacing means you can set the vehicle at exactly the working height you want, not close enough. Quality 27K units use pneumatic locks with steel rack ladders — no plastic components, no hydraulic-only holds. This is not the tier of lift where a bargain safety system is acceptable, and it is worth verifying ALI Gold-label certification on any 27000 lb 4 post lift for sale before you write a check.
Brands and models in this class
The mainstream options at this capacity include the BendPak HD-27 and its HDS-27 short-runway variant, Rotary Lift’s heavy-duty 4-post commercial series, and Mohawk’s TP-30 family for shops that want an American-built commercial-tier lift. We work with all three and if the vehicle mix is on the heavier end of the bell curve we will often recommend stepping up to a 30,000 lb machine — small cost premium, meaningful margin of safety. Our heavy-duty vehicle lift guide and heavy-duty truck lift guide lay out the trade-offs by vehicle class.
Freight, unloading, and receiving
A 27,000 lb 4-post ships as a crated pallet plus loose columns and runways — typically 6,000 to 7,500 lb of freight on two or three pallets. Curbside LTL delivery is standard; a forklift with 8,000 lb capacity or a heavy-duty pallet jack plus a loading dock is required at the receiving end. If your site does not have a forklift we can add a liftgate trailer at quote time, but confirm the truck can turn into the site and that the driveway approach is level. We flag all of this before shipping so nothing surprises the crew on delivery day.
Slab, anchors, and site prep
Slab requirements at this capacity are typically 6 inches of 3,000 psi concrete minimum, wire-mesh reinforced or better, cured a minimum of 28 days. We pull the manufacturer’s exact anchor length and edge-distance specs before shipping so your slab evaluation is not a guess, and we will tell you when a slab is not adequate — cracked pours near columns, thin overlays over vapor barriers, or heaved joints are all disqualifiers.
Nationwide installation and service
We install this class of lift across the country. Installers use the manufacturer’s torque and shim specs, verify plumb on all four columns, cycle-test the safety locks in every position, and pressure-test the hydraulic system before we leave the site. If you buy a 27000 lb 4 post lift for sale from us, ALI-certified installation and factory-authorized warranty startup are options at the quote stage, not upsell surprises. For post-install replacement components we run a full online catalog on our parts lookup page.
Whether you are outfitting a first commercial bay or replacing a tired 24K unit, we can walk you through capacity, runway, and freight logistics before you commit. Call us at 800-674-9302 and we will price the specific model, delivered to your slab, with clean numbers and no ghost fees. A 27000 lb 4 post lift for sale is a 25-year purchase — it is worth getting right the first time, and we will not sell you a lift that does not fit your work.
