상품 특징

• [Unobstructed Lifting with Through-Hole Design]--This hydraulic hollow jack features a central hollow core, enabling it to effortlessly lift longitudinal objects like rods, pipes, or cables passing directly through its center. Ideal for applications where standard jacks fail, it provides unparalleled access and functionality in confined or complex spaces, making it perfect for construction and industrial tasks.
• [Smooth Operation with Automatic Retraction]--Experience seamless performance with a dual-stage ram system: one section initiates movement while the other ensures steady lifting. Once pressure is released, the main shaft retracts automatically without external force, simplifying operation and enhancing efficiency for repetitive tasks.
• [Durable and Portable Build]--Crafted with a baked-enamel finish, this hydraulic hollow ram resists rust and corrosion, ensuring long-term reliability. The integrated handle offers convenient portability, allowing easy transportation and positioning across job sites without compromising durability.
• [Enhanced Stability for Precision Work]--The through-hole design naturally aligns loads like rebars or tendons through the jack’s center, minimizing slip or shift risks during lifting or tensioning. This ensures superior stability and safety, especially in critical applications such as post-tensioning concrete.
• [Universal Compatibility and Versatility]--Equipped with a standard 3/8" male connector, this hydraulic hollow cylinder seamlessly pairs with pumps featuring a 3/8" female interface. Its adaptability extends with accessories for pulling, tensioning, and clamping, making it a versatile solution for diverse heavy-duty applications.
