2-Post Hydraulic Press Configuration
Two-post hydraulic presses, also known as two-column hydraulic presses, are characterized by the two guideposts on the centerline. These posts are positioned to the left and right of the forming area to offer guidance to the ram.
The shallow press bed is well suited for jobs being done on a press brake with traditional tools for forming, punching, and shaping long, narrow parts.
Two-post presses are an economical choice for applications requiring less than 500 tons of force and a forming area shallower than 24 inches.
Rigid Construction of 2-Post Hydraulic Presses
These machines are composed of a crown weldment, ram weldment, and bed weldment joined together by the posts on either side. Hydraulic systems can be crown-mounted in certain instances but are often skid-mounted on the floor due to the limited space above the crown.
If loading from the sides is not required, Beckwood’s 2-post presses are a great alternative to C-frame presses as they require less frame steel to counteract the yawning that can occur with traditional C-frame presses. Additionally, the enhanced ram guidance offered by 2 posts provides for a more precise and linear die alignment when compared to C-frame presses.
2-Post Linear Servo Presses
For increased efficiency and precision, Beckwood is capable of upgrading your 2-post hydraulic press to one that instead uses servo-electric actuation.
Servo-electric actuation can provide a host of many benefits for applications of all kinds. Servo-electric presses are known to boost performance, increase part quality, create an easy user experience, minimize maintenance, and lower operating costs due to energy efficiencies. Servo-electric presses also reduce the carbon footprint associated with both construction and press operation. Whether your work setting is a large-scale manufacturing plant or a small job shop, a servo-electric actuated 2-post press can help ramp up your production.

Custom 2-Post Hydraulic Presses
Our 2-post hydraulic presses have been a popular option for custom configurations due to their cost-effectiveness and robust construction. These are just a few custom Beckwood hydraulic presses that use a 2-post frame:
100 Ton Clamping 2-Post Hydraulic Press
This clamping press was designed for assembly operations for parts to be used in the aerospace industry. Our client opted for a 2-post hydraulic press as a cost-effective solution for their assembly needs. This press was outfitted with multi-zone heated platens for ultimate temperature uniformity and spring-loaded die rollers for front and rear die loading and unloading.
125 Ton Punching 2-Post Hydraulic Press
This custom 2-post hydraulic press was engineered to fabricate blades for machinery in the agriculture industry. Along with the hydraulic press itself, Beckwood was able to provide this client with a unique set of tooling for forming their unique machine blades. This press is equipped with a foot pedal actuator for easy hands-free operation as an added safety measure when forming sharp parts.
125 Ton Embossing 2-Post Hydraulic Press
This custom Beckwood press was created to emboss logos onto mufflers in the automotive industry. For superior rigidity, our customer opted for oversized ram guide bushings to combat the negative effects of off-center loading. In addition, this press was equipped with a regeneration circuit to expedite the hydraulic press cycle and a bed extension to increase operator access for die removal, servo feed, and shear mounting operations.
