In the field of design and manufacture of hydraulic jacks, the introduction of the hollow plunger concept marks a major improvement over the traditional solid plunger design. The hollow plunger design is not only revolutionary in technology, but also brings significant optimization in terms of practicality and economy. In this paper, the main advantages of hollow plunger design and its influence on the performance of hollow ram hydraulic jacks will be discussed in depth.

1. Reduce weight

One of the intuitive advantages of the hollow plunger design is its ability to significantly reduce the weight of the entire hollow ram hydraulic jack. This is because compared to solid plungers, hollow plungers reduce the use of materials while retaining the necessary structural strength. Without sacrificing bearing capacity and stability, the lightweight structure makes the hollow ram hydraulic jack easier to carry and operate, especially for heavy lifting in multiple locations.

2. Increase bearing capacity

Although it may seem contradictory, the hollow plunger design can actually increase the bearing capacity of the hydraulic jack. This increase is not due to a direct increase in structural strength, but is achieved through a more efficient distribution of forces. The hollow plunger allows hydraulic fluid to flow internally, better distributing pressure and reducing the possibility of local stress concentration. This optimization of the pressure distribution means that the carrying capacity of the hollow ram hydraulic jacks can be increased without increasing the external dimensions.

3. Stiffness and stability

The hollow plunger design provides higher stiffness thanks to its closed cylinder shape, which effectively resizes radial and axial pressure from internal hydraulic pressure. In addition, hollow structures are more stable than solid structures, as the latter are more prone to buckling or instability when subjected to heavy loads. High stiffness and stability ensure the performance and safety of hollow ram hydraulic jacks under high load conditions.

4. Thermal diffusion is improved

Under continuous or high load operating conditions, the plunger of the hydraulic jack may generate heat due to internal friction and pressure. The hollow plunger design promotes better heat distribution and heat dissipation through its internal space. This improved heat diffusion helps hollow ram hydraulic jacks maintain lower temperatures during long periods of operation, thereby extending equipment life and maintaining operational efficiency.

5. Economy and cost effectiveness

From a production point of view, the hollow plunger design can reduce material costs because it requires less material to achieve the same mechanical strength. The efficient use of this material makes the production process more economical and reduces the market price of the final product, thus benefiting consumers.

6. Application flexibility

Hollow ram hydraulic jacks show great flexibility in various application scenarios because of their multiple advantages in design. Whether precise control is required in confined spaces or large job sites that require rapid movement and repositioning, hollow ram hydraulic jacks provide reliable performance.

In summary, hollow ram hydraulic jacks occupy an important position in modern industrial applications with their reduced weight, increased bearing capacity, improved stiffness and stability, optimized thermal diffusion and economic efficiency. These features not only improve the efficiency and safety of operation, but also expand the applicability of hollow ram hydraulic jacks in a variety of industrial and commercial environments.
