Lock Nut Hydraulic Cylinders/Self Locking Hydraulic Jack

Engineered for precision and unwavering safety, RIVERLAKE Lock Nut Hydraulic Cylinders redefine reliability in load-holding applications. Combining robust hydraulic power with fail-safe mechanical locking, these cylinders are designed to sustain heavy loads indefinitely—perfect for mission-critical operations where safety and stability are non-negotiable.

Key Features & Benefits:
✓ Mechanical Load Locking Technology: A threaded piston rod and lock ring system securely engages with the cylinder body, enabling extended load retention without hydraulic pressure—eliminating risk of drift or pressure loss.
✓ High-Pressure Resilience: Built to withstand extreme operating pressures, ensuring consistent performance in the most demanding environments.
✓ Diverse Configuration Options: Choose from low-height, lightweight aluminum models for confined spaces or high-tonnage steel variants for heavy industrial applications (capacity tailored to project needs).
✓ Bridge & Infrastructure Excellence: Ideal for bridge construction, maintenance, jacking, and alignment tasks requiring safe, prolonged load holding.
✓ Durable Construction: Corrosion-resistant materials and precision-machined components guarantee longevity, even in harsh outdoor or marine conditions.

Applications:

Bridge bearing replacement and alignment

Structural lifting and stabilization in construction

Heavy machinery maintenance and repair

Industrial jacking operations requiring fail-safe load control

With RIVERLAKE Lock Nut Hydraulic Cylinders, secure your load today—and keep it secured for tomorrow.
