Hydraulic jack is an important machine for tank construction. The equipment is mainly used for inverted construction of vertical cylindrical steel tank (hydraulic lifting method) in petrochemical industry, inverted construction of steel liner in power plant chimney and inverted construction of vertical cylindrical low temperature tank. Next, we will introduce several types of hydraulic jack for you.

●Advanced hydraulic jack

●Simple unfixing Holding -latch hydraulic Jack

●Simple chain type hydraulic jack

Advanced hydraulic jack

T Series Hydraulic Tank lifting device is a large-scale equipment specially designed for the national oil reserve project developed suitable steel giant silo tank inversion welding process engineering.

Features: This type of device is a two-stage single-acting hydraulic cylinder (hydraulic jacks) for VTOL work force or return required from back position, it can not use for horizontal work. Structured compact device, Safe and stable, easy to operate, load adjustable, quick installation, high synchronization accuracy.YT Series Hydraulic Tank lifting device is "dragged five" Oil supply: Each pump station connected to the hydraulic cylinder 5; thus avoiding excessive tubing traditional centralized oil brings. Leakage points more than the disadvantages, to ensure that environmental pollution to a minimum.

Simple unfixing Holding -latch hydraulic Jack

Hydraulic lifting device (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jack and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jack, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.

Simple chain type hydraulic jack

chain type hydraulic jack is composed of one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain and oil way etc. Moveable pulley is used to enlarge chain stroke, i.e. traveling distance of the cylinder is 1/2 of lifting distance of the chain. It applies to inverted installation and construction of various large tanks (steel) and various tanks.

Advantage:

1. Hydraulic lifting is stable, safe and reliable. Due to the adoption of unified hydraulic control and single or partial (several) adjustment, the whole lifting process is relatively stable. The hoist is provided with synchronizing valve and hydraulic lock to prevent sliding and falling of the tank or heavy loads, which are caused by power failure and fracture of oil tube. Hydraulic lifting is stable, safe and reliable. 

2. Construction quality is ensured. As the hoist is provided with synchronizer and adjustable function, lifting height can be controlled accurately. Due to above reasons, quality of the tank is ensured. 

3. The equipment is easy to operate. Construction environment is good and work efficiency is high. 

4. The equipment is well-adapted. As long as the number of hydraulic hoists is increased or decreased, the whole set of equipment can be applied to the inverted hydraulic lifting construction of large storage tanks with different volumes ranging from several thousand cubic meters to tens of thousands cubic meters. 

5. The hydraulic pump station and the hydraulic hoist are placed in the tank for easy operation. Finally, a door-closing plate is reserved to move the equipment out of the storage tank, and the door-closing plate is group welded well. 

6. The hydraulic pump station can be controlled singly or jointly, and has strong construction adaptability and excellent technical performance price ratio. 

7. Short construction period, low cost and good economic benefit. Due to the high degree of modernization and the fast lifting speed of the complete set of equipment, it has low construction cost and good economic benefit. This technology is truly characterized with convenient and centralized control, simple operation, safety and reliability (no falling), accurate control of weld clearance and lifting height of heavy objects, which can ensure the quality of the project, save labor and reduce costs, and achieve remarkable economic benefits.

These are the three types of hydraulic jacking system of our company. Our company Wincoo Engineering Co.,ltd is a hydraulic machinery manufacturing company integrated with design, development, production and sales, which mainly manufactures YT advanced hydraulic jack,LYT-type chain-type hydraulic hoist, SQD unfixing holding-latch hydraulic hoist and supporting products. Such products are mainly used for inverted lifting and installation of steel storage tanks. Founded in 2003, after years of concentrated scientific research and development, the company obtained the patent certificate of "Utility Model Hydraulic Hoist’ issued by "China National Intellectual Property Administration", and the right to use the trademark of "WINCOO" in 2008, so as to enable products of Wincoo Engineering Co.,ltd to quickly become Chinese brands.
