Duff-Norton Air Motor Jacks are offered in several models. These precision built, sturdy, dependable machines employ the use of the screw principle with a built in rotary air motor. Typically used for raising and lowering freight wagons, locomotives and rail rolling stock.
Yale hydraulic jacks are universally popular tools for use in workshops or on site for all kinds of lifting and assembly applications, for construction, ship building, power plants, general engineering, metal fabrication and many more.
Standard jacks with plain piston and jacks with safety lock nuts cannot be used with a lifting claw.
To increase stability, all jacks with long stroke (305 mm) are equipped with an elongated base plate.
