WINCOO Chain Type Hydraulic Jacks – Compact, Powerful & Reliable Heavy Lifting for Tank Construction
WINCOO ENGINEERING CO., LTD., a leading hydraulic lifting equipment manufacturer with extensive industry experience, proudly presents its LYT Series Chain Type Hydraulic Jacks — a cost-effective, high-performance hydraulic lifting system engineered for the inverted construction of large-scale steel storage tanks, oil tanks, grain silos, and various industrial storage structures. The LYT series offers a unique combination of compact design, powerful lifting capacity, and operational simplicity, making it an ideal choice for contractors and engineers seeking efficiency and reliability on demanding job sites.
System Design & Operation
The LYT-type hydraulic hoist is composed of a one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain, and oilway. A key innovation of the system is the use of a movable pulley to enlarge the chain stroke — the traveling distance of the cylinder is precisely 1/2 of the lifting distance of the chain, allowing the jack to achieve greater lifting heights with a more compact cylinder design. This engineering advantage translates directly into reduced equipment footprint and easier on-site handling.
The system is designed for inverted installation and construction of various large storage tanks. The LYT series includes multiple models to suit different project scales:
| Model |
Rated Lifting Capacity |
Piston Stroke |
Chain Stroke |
Max Lifting Height |
| LYT-120-2700 |
120 kN |
1500 mm |
2700 mm |
0 to 4600 mm |
| LYT-200-2700 |
200 kN |
| LYT-300-2700 |
300 kN |
All models operate at a rated oil pressure of 25 MPa, with a rated lifting capacity of 12 to 120 tons per unit. Each cylinder is equipped with double-direction oil-way hydraulic locks for enhanced safety, and reinforced with two adjustable pull rods to ensure structural integrity during operation.

Key Operational Advantages
- Double-stroke efficiency — The movable pulley design effectively doubles the lifting distance relative to cylinder travel, maximizing productivity.
- CE and ISO 9001:2000 certified — Demonstrating WINCOO's commitment to international quality and safety standards.
- Hydraulic locking safety system — Double-direction oil-way hydraulic locks on each cylinder prevent unintended load descent.
- Reinforced construction — Adjustable pull rods provide additional structural reinforcement for demanding lifting conditions.
- Easy maintenance — The robust chain mechanism is simpler to inspect for wear compared to complex cable systems.
For large-scale storage tank construction projects, the LYT Series Chain Type Hydraulic Jacks represent a reliable, cost-effective, and operationally simple solution. With global export availability, remote instruction after-sales service, and a 90-day warranty, WINCOO ensures that every customer receives comprehensive support throughout their project lifecycle.
