The Enerpac RCH603 hollow plunger hydraulic cylinder is a popular rental choice for contractors performing high-capacity anchor testing, structural tensioning, and controlled pulling operations. Its center-hole design allows threaded rods, cables, and anchor bolts to pass directly through the cylinder, making it ideal for proof load testing and tensioning applications requiring greater force than smaller hollow plunger models. Renting provides access to specialized hydraulic equipment without the costs associated with ownership, maintenance, calibration, and storage.
🔹 Best Suited For
High-capacity anchor bolt testing and proof load verification
Hollow plunger tensioning applications
Structural and civil engineering projects
Bridge construction and infrastructure maintenance
Utility and transmission tower construction
Applications requiring controlled pulling force through threaded rods, tendons, or cables
🔹 Key Considerations
Requires a compatible hydraulic pump, hose assembly, and couplers.
Hollow plunger design allows rods, anchors, and cables to pass through the cylinder center.
Proper reaction fixtures are required for anchor testing applications.
🔹 Rental Insight
The RCH603 is a widely used hollow plunger cylinder for contractors requiring substantial pulling and tensioning force while maintaining the flexibility of a center-hole design. Its combination of high capacity, compact dimensions, and versatile operation makes it suitable for demanding testing, maintenance, and infrastructure applications.
Proof load testing applies a specified load to confirm an anchor can hold without failure.
Center hole cylinders allow precise tensile force to be applied directly along the bolt axis, ensuring accurate preload without inducing bending or misalignment.
Center hole cylinders are fully compatible with standard 10,000 PSI hydraulic systems from Enerpac, Simplex, and Power Team when properly matched.
Center hole cylinders typically require a compatible hydraulic pump, hoses, pressure gauge, and appropriate threaded adapters or fixtures.
