A hydraulic workshop press is one of the most versatile machines in modern industry and service workshops. It allows for precise pressing, assembly tasks, and testing with a force far beyond what can be achieved with manual strength or simple mechanical systems. But how exactly does a hydraulic workshop press work—and why is hydraulics at the core of its efficiency?
In this article, you’ll get an easy-to-understand insight into the principles behind a hydraulic workshop press. You’ll learn the difference between the two classic press types -H-frame and C-frame -and gain knowledge on how proper maintenance ensures your investment retains its value year after year.

A hydraulic workshop press utilizes Pascal’s principle: pressure applied to a confined fluid is transmitted equally in all directions. In practice, this means that when a hydraulic pump generates pressure in a closed circuit filled with hydraulic oil, this force is directly transferred to the press’s ram.
Blaise Pascal (1623–1662) was a French physicist who formulated Pascal’s principle: pressure in a confined fluid is transmitted equally in all directions. This principle is used in hydraulic presses, where the pump’s pressure is directly transferred to the ram.
It is precisely this simple yet effective use of hydraulics that allows a hydraulic workshop press to deliver forces ranging from 2 to 200 tons—without compromising precision.
At STENHØJ HYDRAULIK, you can choose between two classic designs: H-frame and C-frame. The choice depends on the nature of the tasks and the physical workshop environment.
The H-frame features an “H”-shaped structure.
The C-frame features a “C”-shaped structure.
The H-frame provides maximum stability and power for heavy pressing tasks, while the C-frame offers flexibility, easy access, and efficient handling for lighter and repetitive operations. The H-frame emphasizes stability and safety, whereas the C-frame focuses on flexibility—both delivering high precision and efficiency.
Both the C-frame and H-frame can be equipped with punch sets, V-blocks, and specialized tools, enabling them to handle everything from precision work to heavy industrial applications.
A hydraulic workshop press is much more than just a tool—it’s a productivity booster.
The advantages are numerous:
That’s why both manufacturing companies and service workshops choose a hydraulic workshop press as a key part of their machinery lineup.
Hydraulic workshop presses are used daily for a variety of tasks:
What these tasks have in common is the need for controlled, consistent, powerful, and safe pressing force-precisely what a hydraulic system provides. For more information on possible applications, see here.
The pressing force is measured in T (tons), and it is crucial to size the press correctly:
Consider both your current needs and future tasks. Choosing a slightly larger model can quickly pay off if demands increase. Keep in mind that a press’s maximum force cannot be increased, but you can always use less force when the task allows.
To make full use of a hydraulic workshop press, you can supplement it with:
The right accessories make your press more versatile, increase productivity, and extend the machine’s lifespan.
A hydraulic workshop press can last for decades—but only if it receives proper care. Professional hydraulic service is therefore essential:
With a professional service agreement, you can schedule maintenance in advance and avoid costly unexpected breakdowns. At the same time, you receive documentation showing that the press always meets current safety standards.
For continuous operation, a service agreement is highly recommended—our experts provide regular checks, replacement of wear parts, and compliance with safety regulations.
A hydraulic workshop press—whether you choose the H-frame or C-frame—is a practical investment in power, precision, and operational reliability. When proper sizing is combined with professional service, you get a solution capable of delivering high performance for many years while providing a significant productivity boost.
