American Forge & Foundry 548SD 60/40/20 Ton Three Stage Air/Hydraulic Axle JackAFF Multi-Stage Jacks are Super Heavy Duty air/hydraulic jacks built tough forthe rigors of Trucking, Agricultural and Fleet business. The piston head design is borrowed from industrial technology, providing a superior low and high pressure seal, which gives these jacks a much better hold under severe load conditions. An integral Descent Metering Valve maintains a controlled and safe lowering of the load. Double polished chromed pistons allow for much tighter tolerances which reduce oil bypassing and reduced ram scoring. Built in overload safety valves prevent damage to unit due to excessive load. Air assisted lowering speeds up ram retraction.
