Double-Acting Hollow Hydraulic Jack
Double-acting hollow hydraulic jacks (Double-Acting Hollow Plunger Cylinders - RRH) are similar to single-acting hollow RCH jacks, featuring a hollow center that allows both tensile and compressive forces to be applied to a workpiece. These jacks, ranging from 30 tons to 145 tons with stroke lengths from 38 mm to 258 mm, are manufactured by Artiman Company based on Enerpac standards. They are used in applications requiring high force for both pulling and pushing. These jacks are equipped with a safety valve to prevent damage and protect the jack from excessive loads. To operate this type of jack, a 1-liter, 700-bar manual hydraulic pump along with a hose, gauge, and gauge base—also produced by Artiman Company—is required.
