OY112A 12Ton Heavy-Duty Hydraulic Bottle Jack

OY112A Heavy-Duty Hydraulic Bottle Jack provides 12-ton capacity with a lift range from 215mm to 400mm, designed for demanding heavy automotive and light industrial lifting tasks where the 10-ton industrial model does not provide sufficient load margin.
The 12-ton rating expands the usable application range to include heavy commercial trucks, larger agricultural equipment, and industrial machinery components that push the practical limits of 10-ton equipment. The threaded saddle extension adds height adjustment flexibility for applications where the built-in stroke must be supplemented.
The overload relief valve is factory-calibrated specifically for 12-ton, and the controlled descent system is designed for gradual, stable lowering of heavy equipment components. These reinforcements are necessary to safely contain the higher hydraulic pressure generated at 12-ton working loads, ensuring long-term durability in repeated heavy-use cycles.
The pump mechanism is operated via a heavy-duty removable steel handle with an extended length to provide the necessary mechanical advantage for raising such massive loads. An integrated overload safety valve is precision-calibrated to automatically bypass pressure when the load exceeds the 12-ton rating, preventing structural damage or cylinder rupture.
