These jacks are designed for heavy duty truck, agriculture, construction, mining, mobile home, oil field, automotive, and marine applications where lifting, pushing, spreading, bending, pressing, or straightening are required. The state of the art design for these jacks reduces repair time, and a “Parkerized” pump piston, ram and extension screw help prevent rust from forming.
The handle is a two piece zinc plated handle, and the jack has a longer wear life due to internally machined oil passages, smooth bearing surfaces and close tolerances, and a no leak “Uniweld” construction. The lightweight forged base provides more steel only where strength is required.
The heavy-duty extension screw and release valve were designed to eliminate parts and reduce the chances of breakage and excessive wear. A safety oil by-pass system prevents the ram from being overextended and causing damage to the cylinder.
