WINCOO ENGINEERING CO., LTD., a leading manufacturer with over a decade of experience in hydraulic lifting solutions, proudly presents its Chuck Type Hydraulic Jacks — a high-performance double-acting hydraulic lifting system engineered for the inverted construction of large-scale steel storage tanks, grain silos, enamel tanks, and other heavy industrial structures.

Designed with a patented upper and lower clamping head mechanism, the WINCOO Chuck Type Hydraulic Jack delivers exceptional lifting accuracy, operational reliability, and long-term durability under the most demanding job site conditions.

The system comprises a PLC-controlled hydraulic pump station, hydraulic cylinders, and rectangular steel frames — all designed for fast installation and convenient on-site operation. The pump station can be placed inside the tank, outside the tank, or between two tanks when controlling two units simultaneously, offering remarkable on-site adaptability.

Specifications may vary by model. Customization is available upon request.

• High Degree of Automation — Supports automatic, semi-automatic, single-point adjustment, and manual control modes for flexible operation.
• Hydraulic and Pin-Lock Dual Safety Mechanism — Ensures zero-slip load retention even during prolonged lifts, providing reliable load-holding even in case of power failure or component malfunction.
• Adjustable Lifting Height with Fine-Tuning Capability — Allows precise butt-alignment of tank wall plates for superior welding quality.
• Robust Corrosion-Resistant Steel Construction — Built to endure harsh industrial environments and extreme weather conditions.
• PLC-Based Synchronization — Delivers micron-level synchronization among multiple jacks, preventing uneven load distribution and structural deformation during lifting.
• Self-Locking Chuck Mechanism — Automatically engages when hydraulic pressure is released, holding the load securely without requiring continuous power input — essential for long-duration lifts and overnight construction stops.

• Large vertical cylindrical storage tank inverted erection (oil tanks, chemical storage tanks)
• Grain silo and enamel tank construction
• Power plant desulfurization tower lifting
• Gas tank and asphalt tank flip lifting installation
• General heavy structure lifting for industrial projects
