The Enerpac RLL4002 is a low-profile, high-tonnage hydraulic cylinder with a locknut featuring a 450-ton capacity, 1.77" stroke, and single-acting load return. The load-return is for weighing, lifting, and positioning applications. The lock nut is tested to 150% of its rated load, which provides safe mechanical load holding for an extended period. It has a built-in tilt saddle to improve side-load resistance. The body, lock nut, and saddle feature a black nitride coating to improve corrosion and wear resistance. The red band signals the end of the stroke, and the over-flow port prevents over-stroke.
