OY9020 20Ton quick-pump Air Hydraulic Jack

The OY9020 20-Ton Quick-Pump Air Hydraulic Jack is a high-efficiency lifting tool that combines pneumatic power with hydraulic precision for rapid, heavy-duty lifting in commercial truck repair, industrial maintenance, and off-road recovery operations. With a rated capacity of 20 tons, it safely lifts large commercial vehicles, buses, heavy trucks, and industrial equipment. The defining feature of this model is its quick-pump pneumatic system, which utilizes compressed air to drive a high-flow hydraulic pump, significantly reducing the time and physical effort required to raise the saddle to the load contact point. 
Unlike conventional hydraulic jacks that rely on manual pumping, the OY9020 connects to a standard shop air supply, allowing the operator to achieve rapid saddle advancement with a simple air valve control. Once the saddle contacts the load, the system automatically transitions to a controlled hydraulic lifting phase, providing smooth, powerful elevation to full height. This air-over-hydraulic design dramatically improves workflow efficiency in busy workshops where time per lift directly impacts productivity.
The low-profile design offers a minimum saddle height 260mm for most heavy vehicle clearances, while the maximum lift height 490mm provides ample space for undercarriage and wheel-end repairs. The air-hydraulic system features a double-sealed hydraulic cylinder that prevents leakage and maintains consistent performance over thousands of cycles.
