60-Ton Double-Acting Hollow Hydraulic Cylinder

'Ōlelo 60-Ton Double-Acting Hollow Hydraulic Cylinder is a high-performance center hole hydraulic jack designed for applications requiring both pulling and pushing force through a hollow piston structure.

Its double-acting design allows hydraulic power to control both extension and retraction, ensuring faster operation, higher precision, and improved efficiency in industrial lifting, tensioning, and maintenance work.

The center-hole structure makes it ideal for bolt tensioning, cable pulling, and threaded rod applications where a solid cylinder cannot be used.

Noi

The 60-ton hollow hydraulic cylinder is widely used in:

• Bolt tensioning systems
• Bridge construction and maintenance
• Steel structure installation
• Cable pulling and tensioning
• Industrial machinery maintenance
• Heavy equipment assembly
• Mining and offshore engineering
• Railway and infrastructure projects

Loaʻa

• Hollow center allows rods, bolts, or cables to pass through
• Double-acting design improves efficiency and control
• Suitable for both pulling and pushing applications
• Strong and stable structure for heavy-duty use
• Faster operation compared to single-acting cylinders
• High precision force control under 700 bar pressure

Working Principle

The cylinder operates using hydraulic pressure on both sides of the piston. Oil pressure extends the piston rod for pushing or tensioning, while reverse pressure actively retracts it, allowing faster and more controlled operation.

'Ōlelo hollow center design enables the cylinder to work directly on threaded rods or cables, making it essential for tensioning systems and structural tightening applications.
