WINCOO Two-Stage Hydraulic Tank Lifting Cylinder – Compact Power for Precise Tank Construction
Product Overview
The WINCOO Two-Stage Hydraulic Tank Lifting Cylinder is the core actuating component of the YT-C Series hydraulic jacking system, delivering powerful and precise lifting force for inverted tank construction. Engineered for durability and efficiency, this dual-stage cylinder is the result of over a decade of practical refinement since its initial development for China's national crude oil reserve project in 1994.
Each cylinder is designed as a single-acting, two-stage hydraulic unit specifically for vertical lifting applications, with return achieved by external force or self-weight. The system's modular nature allows operators to deploy multiple cylinders simultaneously for large-scale tank projects.

Key Advantages
Compact and Powerful
Despite its compact dimensions, each cylinder delivers 125KN of theoretical lifting force, making it suitable for heavy-duty tank lifting applications. The rigorous and compact structure ensures overall force and lateral force are strictly calculated and successfully applied.
Precision Stroke Control
With a stroke tolerance of ±0.5mm and glissade capacity limited to ≤5mm, the cylinder provides the high-precision positioning essential for aligning large tank sections and ensuring weld quality.
Adjustable Lifting Configuration
The hydraulic cylinder can be used for single or multiple lifting height adjustments, as well as centralized control of multiple groups. Operators can lift cylinders separately or in groups, with multi-group integration for enhanced precision and welding results.
Integrated Safety Locking
All cylinders are equipped with safety valves that automatically lock under power failure, hose rupture, or burst conditions, preventing cylinder or tank dropping.
Oil Leakage Prevention
Each cylinder features a single high-pressure hose design to avoid oil leakage issues commonly associated with traditional multiple-hose configurations. The cylinder returns to its initial condition by self-weight.
Tank-Welding Machine Compatibility
The cylinder's basic height is based on the tank shell width, enabling seamless integration with automatic girth welding machines for internal girth seam welding.
Applications
- Inverted Construction of Vertical Steel Storage Tanks: The primary application, using the hydraulic jacking method for efficient top-down tank assembly
- Crude Oil and Chemical Storage Tanks: Suited for capacities ranging from thousands to hundreds of thousands of cubic meters
- Tank Roof and Shell Ring Lifting: Lifting completed tank sections (roof and top shell rings) to heights where subsequent shell plates can be positioned and welded
- Tank Repair and Retrofit Projects: Enables safe lifting of tank sections for maintenance or modification work
Operational Workflow
- Initial Positioning: Sensors calibrate the tank structure's initial position. PLC algorithms adjust hydraulic pressure based on load requirements
- Synchronized Lifting: Dual cylinders driven by PLC commands ensure balanced force distribution. Real-time sensor feedback allows dynamic corrections, minimizing tilt or misalignment
- Safety Protocols: Overpressure relief valves and emergency stop functions are integrated to handle unexpected loads or failures
Note: The cylinder is supplied as part of a complete jacking system including the pump station, steel wire, and strokes. It is not intended for standalone use without the full control infrastructure.
