American Forge and Foundry 3400A - 10 Ton Air Lift Jack

You're working on a 40-foot trailer or a loaded farm truck and a standard floor jack just won't cut it. The American Forge and Foundry 3400A 10 ton air lift jack handles 20,000 lbs. at 200 PSI of shop air - no hydraulic hand-pumping, no straining. Hook it up, press the valve, and you're lifting. That's the difference a dedicated air lifting jack makes when you're dealing with serious weight day in and day out.

The heavy-duty air valve gives you precise lift control so you're not chasing the saddle up and down trying to hit the right height. Extension tubes let you dial in multiple lifting and locking positions, and with a low height of 18" and a maximum reach of 52" when all extensions are in play, this american forge and foundry jack covers a wide range of equipment without swapping units. The 12" lift travel means you've got real working room once you're under there.

AFF has been building shop-grade equipment since 1963. They maintain over 300 service centers nationwide and keep a full supply of replacement parts on hand - so this pneumatic floor jack isn't a throwaway unit when something wears out. You can actually get it serviced or find the parts you need. The removable T-handle tucks away cleanly when you're done, and the large-diameter rubber tread wheels let you move it around the shop without fighting it across the floor.

Free shipping to the lower 48, plus a direct line to our team if you have questions before or after you order. This is a serious air jack lift for serious work - and it's backed by a brand that's still around to support it.

Installation & Setup

Air Supply Requirements

This air operated jack requires a shop air supply delivering a minimum of 200 PSI to reach its full 10-ton rated capacity. Make sure your compressor and line can sustain that pressure under load before you put the jack to work. Undersupplying air pressure won't just limit lift performance - it can create an unsafe lifting condition under heavy equipment.

Positioning and Stability

Place the jack on a firm, level surface. The large-diameter rubber tread wheels make repositioning easy on a shop floor, but always confirm the base is fully stable and the saddle is properly seated on the lift point before raising any load. With equipment in the 20,000 lb. range, there's no margin for an improperly positioned jack.

Extension Tube Setup

Attach extension tubes to achieve your target lift height before raising the load. Each tube adds a locking position, giving you flexibility when working under vehicles and equipment at varying clearances. Remove the T-handle once positioned for cleaner access in tight spaces, and store it somewhere it won't become a trip hazard under the vehicle.

Applications

Semi-Trailers and Large Trucks

When a loaded trailer needs to come up and stay up, you need rated capacity and reliable locking. The 3400A's 10-ton air jack lift capability and multiple locking positions keep heavy freight equipment safely supported while you work underneath.

Bus and Transit Fleet Maintenance

Bus bays move fast. An air lift jack that lifts at the press of a valve instead of hand-pumping saves time on every bay cycle and reduces fatigue on your techs during back-to-back lifts.

Farm and Agricultural Equipment

Tractors, combines, and implements sit at varying ride heights with serious weight behind them. The 18" to 52" height range on this air lifting jack covers the wide variance you'll find across a typical equipment yard.

Construction and Industrial Equipment

Loaders, excavators, and heavy construction machinery demand a jack that won't flinch under real-world load. This heavy duty air jack handles industrial lifting scenarios where a standard floor jack would be completely out of its depth.

Frequently Asked Questions

What air pressure does the AFF 3400A require to reach its full 10-ton capacity?

The AFF 3400A reaches its full 10-ton (20,000 lb.) rated capacity at 200 PSI of shop air. Make sure your compressor and air lines can sustain 200 PSI under load. Supplying less pressure will reduce effective lifting capacity and can create an unsafe condition under heavy equipment.

What is the minimum and maximum lift height on this jack?

The 3400A has a low height of 18" and reaches a maximum height of 52" when all extension tubes are installed. The 12" of lift travel and multiple locking positions via the extension tubes give you flexibility to work under a wide range of vehicle and equipment types.

Can I get replacement parts if something wears out?

Yes. American Forge and Foundry maintains a full supply of replacement parts and operates over 300 authorized service centers nationwide. This is a serviceable unit with long-term support behind it - not a throwaway jack. You can also find the official parts diagram in the Documents section above.
