A tractor or heavy truck that needs lifting stops the job until the right jack rolls into place. This 35-ton air-hydraulic floor jack handles the weight of the heaviest equipment in the fleet, lifting up to 77,000 pounds from a starting height of 10 inches to a maximum saddle height just over 21 inches. The stroke length is 6.1 inches, giving enough travel to raise the axle off the ground and get stands underneath in one cycle.The jack runs on compressed air when a 3 HP compressor is connected at 90 to 145 PSI. Hook up the air line and the piston does the work. When compressed air is not available, the manual hydraulic pump takes over, so the jack is never useless on a remote job site. Four saddle adapters are included, sized at 10mm, 25mm, 60mm, and 100mm. Swap them onto the saddle to match the shape of the frame, axle, or lifting point and keep the load seated securely.The frame is carbon steel. The overload valve vents pressure before the jack sees more than it was built to hold, and the non-slip base keeps the jack planted when the ground is uneven or slick. The 46-inch handle adjusts through a 90-to-180-degree arc, letting you pump from the best angle for the space you are in. Eight-inch rubber tires roll over cracked concrete and gravel without skidding or marking the floor. The blue powder-coated finish resists rust and makes the jack easy to spot in a crowded shop.Specifications:Capacity: 35 tons (77,000 lb)Min Saddle Height: 10 in (without adapter)Max Saddle Height: 21.19 inStroke: 6.1 inHandle Length: 46 in, adjustable 90-180 degreesWheel Diameter: 8 in rubber tiresAir Pressure: 90-145 PSI, 3 HP compressor recommendedAdapters: 10mm, 25mm, 60mm, 100mmMaterial: Carbon steelColor: BlueIncluded:1 × 35-Ton Air Hydraulic Floor Jack4 × Saddle Adapters1 × 46-in Adjustable Handle
