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. Hydraulic Pump Station Specifications | Model | Tank Volume | Rated Flow | Motor Power | Rated Pressure |
|---|
| YB-7.2 | 220L | 7.2L/min | 5.5 kW | 25 MPa | | YB-14.5 | 340L | 14.5L/min | 7.5 kW |
The pump station supports three-phase four-wire 380V power supply
with 220V solenoid valve control voltage. 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. |
