column information in the field of hydraulic machinery, relying on friends [20 years] industry deep plowing experience, focus on the output of hydraulic technology innovation, market trends, application cases and other high value content. With the aim of "professional, timely and deep", we provide one-stop information service for engineers, purchasing decision makers and industry researchers, helping users to accurately grasp the pulse of hydraulic technology development.
Hydraulic machine according to the frame structure can be divided into four column type, frame type, single column type. At present, the mainstream hydraulic press is to choose four-column and frame type, because the single-wall hydraulic press is only suitable for small presses below 500 tons. We said respectively 2...
