AFF 80-50-Ton 2-Stage Air Hydraulic Axle Jack

The American Forge & Foundry 549SD 80/50-Ton 2-Stage Air Hydraulic Axle Jack is built to handle the most demanding heavy-duty lifting applications, including trucking, agricultural equipment, construction machinery, military vehicles, and aircraft service. Engineered for exceptional strength and reliability, this super-duty axle jack features advanced industrial piston head seal technology for superior load holding under both low- and high-pressure conditions. Its rugged single-piece base construction and double-polished chrome pistons provide outstanding durability, reduced wear, and consistent hydraulic performance in the toughest environments.

The extra-long 54-inch handle locks into three positions for easy positioning beneath hard-to-reach lifting points. An integral descent metering valve delivers safe, controlled lowering of heavy loads, while the air-assisted lowering system speeds ram retraction for increased productivity. A built-in overload safety valve helps protect the jack from excessive loads. The included saddle adapter and 1.75-inch and 3-inch extensions provide added versatility, and the jack is tested to perform reliably in extreme temperatures and demanding operating conditions.
