OY1100B 100Ton overload-protected Hydraulic Bottle Jack

The OY1100B 100-Ton Overload-Protected Hydraulic Bottle Jack is a ultra-heavy-duty vertical lifting solution engineered for extreme industrial applications including mining equipment repair, heavy civil engineering, shipbuilding, steel mill maintenance, and large-scale infrastructure projects. With an immense rated capacity of 100 tons, it safely and reliably lifts massive loads such as mining excavators, industrial forging presses, bridge sections, railway rolling stock, and heavy transformer units. The critical safety feature of this model is its precision overload protection system, which integrates a factory-calibrated high-pressure relief valve that automatically disables the lifting mechanism if the load approaches or exceeds the 100-ton limit.
The hydraulic system is engineered for sustained performance under extreme pressures exceeding standard industrial jacks. The lifting range typically extends from a minimum saddle height of approximately 340 mm to a maximum height of 520 mm, accommodating the substantial ground clearance and structural profiles of ultra-heavy machinery and industrial equipment.
The cylinder body is forged from premium alloy steel, heat-treated, and coated with an ultra-heavy-duty industrial finish that resists oil, chemicals, impact, abrasion, and extreme corrosion.  The top saddle is a large-diameter swivel type with a hardened, aggressively textured surface to securely engage irregular, greasy, or uneven lift points without slippage.
