Established Reliability

Airbag lifting technology was developed in the '40s, before hydraulics, as the safety industry commercialized it to raise and stabilize derailed train cars, overturned tractor-trailers — even collapsed bridges. Soon after, Kelley innovation brought this same dependable, economical lifting technology to docklevelers, eventually making the aFX Dockleveler the most popular model on the market!

The Kelly airForce™:
Air Superiority

Now, Kelley's patented aFX Dockleveler takes you to the next level of performance. While still delivering all the air-powered pluses we introduced to the industry — simple, durable, clean-running operation, lubrication and adjustment-free activation, plus minimal moving parts — our airDefense now eliminates stump-out, offering increased free-fall protection. Our airForce Technology (aFX) means there's no need to install hydraulic docklevelers to obtain stump-out-free operation. And means doing business without Kelley is dangerous business.
