Foundry 80\/50 Ton 2 Stage Air Hydraulic Axle Jack\u003c\/h2\u003e\n    \u003cp\u003ePutting a jack under a semi, a combine, or a piece of heavy construction equipment isn't the moment to wonder if your equipment has enough capacity. The AFF 549SD is an American Forge \u0026amp; Foundry axle jack that delivers 80 tons on the first stage and 50 tons on the second - one unit that covers heavy-duty trucking, agricultural equipment, construction machinery, military vehicles, and aircraft. That's not a marketing claim about versatility. That's two lifting stages in one body, each rated for the kind of load that puts lesser axle jacks out of their range.\u003c\/p\u003e\n    \u003cp\u003eThe piston head seal borrows from industrial sealing technology - the same design used in heavy manufacturing presses, not consumer-grade equipment. You get a stronger hold at both low and high pressure, which matters when you're keeping serious weight off the ground for extended periods. Double polished chromed pistons maintain tighter tolerances than standard machining allows, which cuts down on oil bypassing and protects the ram from scoring over time. The single-piece base adds genuine stability - there are no bolted joints to flex or shift when the load is at its heaviest.\u003c\/p\u003e\n    \u003cp\u003eThe 54-inch handle locks at three positions so you can work into a tight spot without repositioning yourself around the vehicle. Integral Descent Metering keeps the load coming down controlled and steady - this is not a valve you hope holds. Air-assisted ram retraction brings you back to low height faster between lifts. The built-in overload safety valve shuts things down before an excessive load can damage the unit. Every one of these features answers a real failure mode on inferior hydraulic axle jacks.\u003c\/p\u003e\n    \u003cp\u003eAFF tested this pneumatic hydraulic axle jack from -13F to +113F (-25C to +45C) and ran off-center loading tests to confirm performance under real field conditions. Cold shop in January or outdoor fieldwork in July - the 549SD is rated for both. Free shipping to the lower 48 means no freight bill shows up after checkout. Real support is one call away when you need it.\u003c\/p\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"specifications\"\u003e\n    \u003ch2\u003eSpecifications\u003c\/h2\u003e\n    \u003ctable class=\"gsg-spec-table\"\u003e\n      \u003ctbody\u003e\n        \u003ctr\u003e\n\u003ctd\u003eStage 1 Capacity\u003c\/td\u003e\n\u003ctd\u003e80 Tons\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eStage 2 Capacity\u003c\/td\u003e\n\u003ctd\u003e50 Tons\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eLow Height (Both Stages)\u003c\/td\u003e\n\u003ctd\u003e9.06 in (230 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eStage 1 High Height\u003c\/td\u003e\n\u003ctd\u003e13.39 in (340 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eStage 2 High Height\u003c\/td\u003e\n\u003ctd\u003e17.32 in (440 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eStage 1 High Height w\/ Extensions\u003c\/td\u003e\n\u003ctd\u003e19.14 in\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eStage 2 High Height w\/ Extensions\u003c\/td\u003e\n\u003ctd\u003e23.07 in\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eStage 1 Lift\u003c\/td\u003e\n\u003ctd\u003e4.33 in (110 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eStage 2 Lift\u003c\/td\u003e\n\u003ctd\u003e8.27 in (210 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eWorking Air Pressure\u003c\/td\u003e\n\u003ctd\u003e116 to 174 psi (0.8 to 1.2 MPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eHandle Length\u003c\/td\u003e\n\u003ctd\u003e54 in (138 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eHandle Lock Positions\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e233 lbs (106 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e240 lbs (109 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eTemperature Range (Tested)\u003c\/td\u003e\n\u003ctd\u003e-13F to +113F (-25C to +45C)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003c\/tbody\u003e\n    \u003c\/table\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"whats-included\"\u003e\n    \u003ch2\u003eWhat's Included\u003c\/h2\u003e\n    \u003cul class=\"gsg-included-list\"\u003e\n      \u003cli\u003eAFF 549SD Axle Jack\u003c\/li\u003e\n      \u003cli\u003eExtension - 75 mm (3\")\u003c\/li\u003e\n      \u003cli\u003eExtension - 45 mm (1.75\")\u003c\/li\u003e\n      \u003cli\u003eSaddle Adapter\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"installation\"\u003e\n    \u003ch2\u003eInstallation \u0026amp; Setup\u003c\/h2\u003e\n    \u003cp\u003eThe 549SD runs on compressed air.
