The Norco 76503B is a professional-grade 3-ton capacity bottle jack engineered for reliability in the toughest work environments. Designed with Norco's proven "Uniweld" construction and advanced safety features, this bottle jack delivers the lifting power you need for heavy duty truck, agriculture, construction, mining, mobile home, oil field, automotive, and marine applications. Whether you're lifting, pushing, spreading, bending, pressing, or straightening, the 76503B provides consistent performance with an impressive 50% safety overload factor for added peace of mind.
Built for durability and longevity, the 76503B features a two-piece zinc plated handle, rust-resistant "Parkerized" pump piston, ram, and extension screw, and a lightweight forged base that provides strength exactly where it's needed without adding unnecessary weight. With a low lift height of 7.5" and a high lift height of 15.5625", plus 2.8125" screw extension, this jack offers versatile lifting range for a wide variety of jobs. At just 8 lbs. shipping weight, it's portable enough to move around the shop or job site with ease.
The Norco 76503B is engineered with premium components designed to minimize maintenance and maximize uptime. The cold-headed extension screw and release valve eliminate unnecessary parts, reducing the chances of breakage and excessive wear. The lightweight forged base concentrates steel only where structural strength is required, improving portability without sacrificing stability. Internally machined oil passages, smooth bearing surfaces, and close tolerances ensure longer wear life and smoother operation over thousands of lift cycles.
Safety is paramount. The integrated overload valve protects the jack from exceeding its rated capacity, while the safety oil by-pass system prevents the ram from being overextended—protecting both the cylinder and the load. The two-piece zinc plated handle resists corrosion and provides comfortable, reliable operation in all conditions.
Intended Use: The Norco 76503B is built for demanding work in heavy duty truck, agriculture, construction, mining, mobile home, oil field, automotive, and marine applications where lifting, pushing, spreading, bending, pressing, or straightening are required. From roadside truck repairs to agricultural equipment maintenance, from construction site rigging to marine vessel work, this bottle jack delivers the performance professionals rely on.
