RK Machinery manufactures hydraulic press machines such as H Frame Presses and C Frame Presses. Our hydraulic machines have all the features to satisfy skilled operators, yet are simple enough for the inexperienced hydraulic shop press operators. Using a hydraulic cylinder to produce a compressive force, the hydraulic press, was also known as the Bramah press after its inventor, Englishman, Joseph Bramah. The hydraulic press relies on Pascal’s principle which states that pressure within a closed system is constant. At RK Machinery, we will custom build hydraulic presses according to your specifications therefore ensuring that the H Frame Press or C Frame Press that you purchase will meet your exact needs and specifications.

H Frame Press
Our H Frame Presses are available in multiple models ranging from 20 tons to 350 tons; certain models are available in extra wide. Our H Frame Presses come with unique standard features such as.

A low pressure hydraulic system which maintains lower oil temperatures, resulting in higher efficiency and safer operation.
Large bore cylinders averaging 3,800 P.S.I. maximum pressure throughout our complete line of H Frame Presses. Working at a lower pressure means less heat and with higher efficiency and most important of all much less risk of liability issues. Most other manufacturers use small bore cylinders at 700 bar equal to 10,152 P.S.I. operating pressure. All our hydraulic and mechanical parts are standard in the industry and available throughout North America.

C Frame Press
Our C Frame Presses are available in 20 ton or 50 ton models. Our C Frame Presses are built with dual controls which enable operators to select from either a moveable pedestal complete with dual electric palm buttons and extra emergency stop, or a foot pedal. See the complete specs to review the wide range of other standard features.
