Double Acting, Hollow Ram, Hydraulic Jacks
Introducing BEMCO JACKS’ Double Acting Hollow Ram Hydraulic Jacks, engineered for superior performance and durability in demanding industrial applications. Crafted from high-grade, hardened, and tempered alloy steel, these hollow jacks are designed for both push and pull operations, offering versatility in lifting, tensioning, testing, and pulling tasks. With a center hole jack configuration, they can be used efficiently with a bar for pulling. These jacks come equipped with a safety pressure relief valve to prevent over-pressurization during retraction, ensuring safe operation. Built to ASME standards, all exposed surfaces are hard chrome plated and black anodized for enhanced corrosion resistance, guaranteeing longevity and reliability.
