Key Features & Benefits
- 3-ton lifting capacity with a 50% safety overload factor for maximum protection
- "Uniweld" no-leak construction ensures long-lasting reliability and prevents hydraulic fluid loss
- Parkerized components (pump piston, ram, extension screw) resist rust and corrosion in harsh environments
- Overload valve and safety oil by-pass system prevent overextension and cylinder damage
- State-of-the-art design with internally machined oil passages and close tolerances for reduced repair time and longer wear life
- Compact 4" x 4.5625" base provides stable support while maintaining portability
Professional-Grade Construction
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.
