Lift heavy trucks, tractors, and trailers without spending the whole job on the jack. This 35‑tonne air hydraulic floor jack uses shop air to raise the load quickly, then holds it steady while you work.Heavy‑Duty Lifting CapacityThe 45# steel frame and reinforced lift arm handle up to 77,000 pounds, making this floor jack suitable for dump trucks, semi‑trailers, and large agricultural equipment. The low‑profile design starts at just 10 inches high, clearing axles and frames on lowered or heavily loaded vehicles.Secure Fit with Four AdaptersFour steel saddle adapters (10, 25, 60, and 100 mm) let you match the contact point to the shape of the frame or axle. Swap them without tools to lift round tubing, box‑section frames, or flat surfaces securely. The grooved saddle grips the load, reducing the chance of slipping during lifting.Dual Power and Smooth ControlConnect a 3HP or larger air compressor (90 to 145 PSI) and the jack rises quickly under pneumatic pressure. When air is not available, the manual hydraulic pump handle provides full lifting power. The 46‑inch handle adjusts its angle, letting you pump from a comfortable position even when the jack is tucked under a vehicle.Safety Built into the DesignAn overload valve prevents lifting beyond the rated capacity, and the slow‑release valve lets you lower loads in controlled steps. The wide steel base and non‑slip pads keep the jack steady on concrete or asphalt. Eight‑inch rubber tires roll smoothly over workshop floors and absorb vibration without skidding.This air hydraulic jack runs on standard workshop air and requires no special adapters. The four included saddle adapters cover most commercial vehicle frames, and the compact low‑profile body stores upright against a wall when not in use.
