The Torin TCE AT92003BU hydraulic bottle jack is designed for residential and commercial use. It is industrial welded and engineered using a drop forged alloyed steel construction that is ideal for quality and durability. The inner/outer welded structure delivers leak-free performance and has a longer operation life and an overall stronger build compared with traditional screw jacks. The fully welded structure is designed for hard-hitting commercial use, making large loads easy to lift. A wide, rugged base adds stability and strength. Features a lifting range of 9-7/16" to 17-5/8" with a 20 ton (40,000 lb) capacity. It has a lifting height of 5-7/8" and an adjustable screw top extension that adds an additional height of 2-3/8". The 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. Piston ram utilizes a Y-style polyurethane sealing ring with backup ring, preventing the load from falling slowly. This powerful bottle jack is ideal for lifting cars, trucks, SUVs, farm vehicles, heavy-duty machinery and industrial equipment. It can also be used for military applications, agricultural and industrial environments where the equipment receives heavier abuse. This unit is 100% factory tested for reliability and safety to meet and comply with ASME PASE safety standards.
