With a 4-column press, the upper and lower traverse are connected by means of pre-tensioned tie rods. This offers two main advantages: On the one hand, this allows for an optimized deflection compensation of the construction. On the other hand, machine operators can access the tool area of the press from all sides. This allows the application of hydroforming tools which, including the cylinders, are larger than the actual table surface.
4-column presses are used for a wide range of application. They are standardized for closing forces of 630, 800, 1,000, 1,200, 1,500, 1,700, 2,000, 2,500, 3,500 and 5,000 tons.
