Hydraulic Ram Jack 50T Low Profile Porta Power Cylinder Multi-Section 2.56 inch Stroke Lifting Cylinder for Machinery Shipbuilding Bridge Construction

Features

• [Product PARAMETERS]---Tonnage: 50T | Stroke 1: 0.78"| Stroke 2: 0.9" | Stroke 3: 0.86" | Total stroke: 2.56" | Self height: 2.8" | Weight: 19.8 lbs | Effective area: 0.087 sq.in. | Inner diameter 1: 1.18" | Inner diameter 2: 2" | Inner diameter 3: 3.18" | External diameter: 5.2" x 6.1"
• [Multi-Section Design for Narrow Spaces] - This hydraulic cylinder is small in size, but strong in load-bearing capacity, with the self height of just 2.8 inches while delivering an impressive 2.56-inch stroke., easily fits into tight spaces, and can lift 50T heavy objects, which is especially suitable for lifting and supporting work in narrow spaces.Compared to single-section jacks, this multi-section hydraulic jack delivers precise height control, enhanced stability, and superior safety for your construction operations.
• [Durable Powder-Coated Finish Rust-Resistant & Smooth] -The integrated molding of the hydraulic cylinder , along with the outer rust and corrosion-resistant coating, ensures long-term reliability and durability. Smooth surface reduces friction loss and protects loaded surfaces from scratches.
• [Manual Return Mechanism] This jack features a gravity-return design - the ram WILL NOT retract automatically after pressure release It requires light downward pressure from the load or manual assistance to reset, ensuring stable load control and prevents sudden retraction hazards.
• [Wide Applications] - This hydraulic jack can be widely used in the installation and maintenance of large and medium-sized machinery and equipment in the petroleum, electric power, metallurgical, steel, ship, bridge and other industries.However, it does NOT apply to cars. The porta power ram should be used with hydraulic pumps. The 30T/50T can be used with CP-700 hydraulic pump (ASIN: B08QV222RP).
