OY9030 Heavy-Duty 30Ton Air Hydraulic Jack

The OY9030 Heavy-Duty 30-Ton Air Hydraulic Jack is a powerful pneumatic-over-hydraulic lifting system engineered for extreme heavy-duty applications in commercial truck repair, industrial equipment maintenance, mining service facilities, and off-road recovery operations. The defining feature of this model is its air-over-hydraulic quick-pump system, which uses standard shop compressed air to drive a high-volume hydraulic pump. This design eliminates the physical effort of manual pumping and dramatically reduces the time required to raise the saddle to the load contact point. Once the saddle engages the load, the system seamlessly transitions from rapid approach to controlled high-pressure lifting, providing smooth, powerful elevation up to the maximum height. For workshops and field operations where lifting heavy loads repeatedly is routine, the OY9030 delivers exceptional productivity gains while minimizing operator fatigue.
The booster cylinder on this model uses a large-area pneumatic piston coupled to a high-volume hydraulic pump, delivering an oil flow rate that moves the main cylinder at a lifting speed approximately three times faster than a comparable manual hydraulic jack.
The main cylinder is manufactured from thick-wall seamless steel tubing that is internally honed and externally turned to provide a precision-ground seating surface for the piston seal package. This construction method is more expensive than casting but produces superior dimensional consistency and longer seal life.At 22 kg net weight, the OY9030 requires two people or a trolley to move safely, acknowledging that at 30-ton capacity, operational robustness takes priority over single-person portability.
