The Torin BIG RED T30808 hydraulic long ram jack has a double piston pump and clevis base that is designed for residential and commercial use. Fits most garage/shop cranes, engine hoists, and more. The lifting range is 24-13/16" to 44-1/8" with a 8 ton (16,000 lb) load capacity. This long ram jack is constructed of heavy-duty steel with a heat-treated chrome cylinder for added strength. It features a high-quality glide-action pressure pump designed to lift with minimal muscle and effort and has an integrated built-in oil-bypass and overload valve that protects the hydraulic system from extending beyond its travel limits. Hydraulics are powered with a high-quality oil, which offers better corrosion resistance and high/low temperature flexibility, allowing the unit to operate at temperatures between 40 degrees Fahrenheit and 105 degrees Fahrenheit. The piston ram is treated and polished to resist skiving and utilizes a Y-style polyurethane sealing ring with backup ring, preventing the load from falling slowly. The clevis style base provides added versatility. After a thorough chemical wash to ensure a long-lasting finish and to help prevent rust, it's treated with a powder-coated, lead-free paint, providing a durable coating which is oil, grease, and dirt-resistant for easy cleanup.
