The HRA double Acting High Tonnage Aluminum cylinder

The HRA double-acting high-tonnage aluminum cylinder is a specialized hydraulic tool designed for heavy lifting applications where portability is a key concern. Here are its features and benefits:   

Key Features:

Double-acting design: Double-acting cylinders are different from single-acting cylinders because they do not rely on gravity or a spring for retraction. Instead, they use hydraulic pressure for both extension and retraction. This gives better control and faster cycle times, especially in horizontal or angled applications.

High Tonnage Capacity: They are designed to be used in heavy lifting, with a capacity of most from 30 to over 100 tons. Such high tonnage capacity can make them suitable for tough jobs in many industries.   

Aluminum Fabrication: The use of high-strength aluminum alloys makes the cylinders much lighter than its steel variants. This is important in applications where it must be portable and easy to manipulate. 
The piston rod and cylinder are often hard anodized to increase wear and corrosion resistance in harsh environments.  

Safety Features: The cylinders typically come with anti-extrusion seals that prevent damage to the seals under pressure and safety valves preventing over-pressurization.  

Handles: Larger models generally incorporate handles for better handling and positioning.  

Advantages of Use of HRA Cylinders:

Portability: The aluminum construction makes these light in weight to be moved along and positioned, thus reducing the setting up time and labor costs.

Increased Efficiency: Double acting design provides for faster and better-controlled lift and lowering
Durability: Hard anodized finish and strong construction offer long-lasting performance in demanding applications

Versatility: These are applicable for lifting, pushing, or pulling a wide range of applications across all kinds of industries.
