Four-post presses, also known as 4-column presses, can be designed to accommodate dies of any size and are well-suited for for nearly every industry and application. They are composed of a crown weldment, ram weldment, and bed weldment joined together by steel posts on all four corners. These machines offer ultimate access to all sides of the working area and are one of the most flexible and most common press designs, with tonnage capacities up to 10,000+ tons. Hydraulic systems can be crown-mounted or skid-mounted with ease to accommodate any footprint requirements, and forming areas vary widely from very small to very large depending on the application.
With a 4-post hydraulic press, there are virtually no restrictions on tonnage or bed size, and when used in conjunction with Beckwood’s proprietary Active Leveling Control System, they maintain precise bed-to-ram parallelism during off-center loading applications. Beckwood custom hydraulic and servo-electric 4-post presses are designed with modular tie-rod construction and built for Infinite Life™.
Whether you choose hydraulic or servo-electric actuation, each 4-post press is guided by replaceable, graphite-impregnated bronze bushings and solid, chrome-plated posts to ensure years of maintenance-free, reliable operation. Beckwood’s precision bushings provide superior ram guidance and eliminate the need for external lubrication.
