WINCOO
Product Introduction
WINCOO ENGINEERING CO., LTD., headquartered in Jiangsu, China, is a leading manufacturer specializing in the research and development of LYT-type chain-type hydraulic hoists, SQD-type hydraulic hoists, and supporting construction equipment-. With over a decade of industry experience and certifications including CE and ISO 9001:2000, WINCOO provides reliable and innovative tank lifting solutions for global construction projects.
The LYT-type chain-type hydraulic jack is an advanced lifting system specifically designed for the inverted installation and construction of large steel storage tanks. The system is composed of a one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain, and hydraulic oil circuit. By utilizing a movable pulley configuration, the system amplifies the chain stroke—the traveling distance of the cylinder is exactly half of the lifting distance of the chain. This mechanical advantage allows for efficient, controlled lifting with minimized cylinder travel.
Product Specifications
The LYT series offers three standard models with customizable options available for special stroke requirements. The technical parameters are as follows:

Product Advantages
The WINCOO chain-type hydraulic jack offers multiple advantages over conventional lifting methods:
Stroke Amplification: The movable pulley design effectively doubles the lifting stroke relative to cylinder travel. With a cylinder stroke of only 1,500 mm, the system achieves a full 2,700 mm chain stroke, reducing the number of lifting cycles required.
Superior Safety: Each hydraulic jack is equipped with a double-direction oil-way hydraulic lock that prevents load slippage. Even in the event of power failure, hose rupture, or cylinder malfunction, the load remains securely locked in position.
Energy Efficiency: The system operates at a rated pressure of 25 MPa and requires minimal energy input relative to the lifting force generated, making it an energy-saving solution for large-scale tank construction.
Precision Control: The system supports both manual and centralized control modes. Multiple jacks can be centrally operated for synchronized lifting, while individual jacks can be fine-tuned for precise height adjustments—critical for aligning tank wall weld joints.
Customizability: Special stroke configurations are available upon request. WINCOO also calculates the optimal number of hydraulic jacks based on tank weight to ensure safe and efficient lifting.
Applications
The LYT-type chain-type hydraulic jack is primarily used for the inverted construction method (also known as the “jack-up method”) of large storage tanks. Typical applications include:
Oil and Petrochemical Storage Tanks: Fixed-roof tanks, floating-roof tanks, and spherical tanks for crude oil and refined products.
Steel Storage Tanks: Large-capacity steel tanks for water, chemical, and industrial storage.
Grain Silos: Flat-bottom corrugated board granaries and grain storage facilities.
Enamel Tanks: Enamel storage tanks requiring inverted installation techniques.
LNG Tanks: Large-scale liquefied natural gas storage tanks requiring precise and synchronized lifting.
The inverted method lifts the tank roof and upper wall panels first, then sequentially lifts the assembly to weld lower wall sections. This approach significantly reduces the need for aloft work and scaffolding, improving both safety and construction efficiency.
