Do you know the tank hydraulic jacking system?Understand it?Do you know how it jacked up the tank?And do you know how much weight it can lift? Although hydraulic jacking system have been widely used in the construction of large tanks, many people still know little about them. Today I will give you a good introduction to the hydraulic jacking system from the following aspects.
●What is the hydraulic jacking system?
●How does the hydraulic jacking system lift the tank?
●How much weight can the hydraulic jacking system lift?
Hydraulic jacking system 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.
At present, we have three types of hydraulic jacking system in WINCOO Engineering Co., LTD. They are the following three: Advanced hydraulic jacking system, Simple unfixing Holding -latch hydraulic Jacking system and Simple chain type hydraulic jacking system.
Hydraulic jacking system (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 jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jacking system, 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.
1.The number of hydraulic cylinders used for the same size tank is different according to the actual use and weight of the tank.
2.Regardless of tank size, hydraulic cylinder installation must be evenly distributed.
3.Construction of different tanks and selection of YT series hydraulic lifting equipment number and calculation of lifting equipment load rate specification: lifting equipment load rate must be less than 80%.
For example, for a storage tank with a volume of 50,00m3 and a diameter of 60m, the maximum weight of the lifting body of the tank is 536T (excluding the weight of the bottom plate of the tank), 40 hydraulic cylinders of YT25-2700 are selected, and the output force of each hydraulic cylinder is 250KN, so the total output force of the lifting device is 25O×40=10000KN.The load rate of the lifting equipment is 536x9.8÷10000×100%≈52.53%, which meets the requirement of less than 70%.
The above is our brief introduction to the hydraulic jacking system. If you have any questions, you are welcome to browse other relevant articles and products on our website. I hope the above content will be helpful to you.

Hydraulic storage tank lifting equipment is a kind of jack that uses a plunger or a hydraulic cylinder as a rigid jacking member. Simple lifting equipment is generally only equipped with a lifting mechanism to lift heavy objects.
Why do we maintain hydraulic storage tank lifting equipment in the right ways?
Why can't the hydraulic storage tank lifting equipment lift go up?
What are the advantages of hydraulic storage tank lifting equipment?
(1) The bottom of the hydraulic storage tank lifting equipment should be flat and tough when used. Oil-free planks to expand the bearing surface and ensure safety. Can not use iron plate instead of wood, to prevent sliding.
(2) When lifting, it is required to be stable. After the heavy object is lifted for a while, it is necessary to check whether there is any abnormality. If there is no abnormality, the roof can continue to be lifted. Do not lengthen the handle arbitrarily or operate it too hard.
Most of the hydraulic storage tank lifting equipment lift hydraulic power source is used for lifting and lowering operations. With the aging of the mechanical structure, some small faults will inevitably occur after long-term use, such as the lift does not lift, so what is the reason? The hydraulic lift cannot afford There are many reasons for the rise, the common ones are:
1. The load is too heavy, exceeding the rated load, and the load can be reduced.
2. The oil return valve is not closed, causing the hydraulic system to not work normally, and the oil return valve needs to be tightened.
3. The filter is blocked, replace or clean the filter.
4. If the hydraulic oil is insufficient, add enough hydraulic oil to the lift.
Main features of hydraulic storage tank lifting equipment:
1. The system consists of hydraulic pump station, oil cylinder, steel wire and stroke. Easy to install and operate;
2. The system adopts PLC central control to handle elevators. Each power pack is equipped with an auxiliary balance device to ensure the accuracy of simultaneous lifting;
3. The hydraulic lifting pump station has two operation modes: auxiliary manual control and central control. The cylinder can be adjusted to lift individually or in multiple groups, or in combination with multiple groups to achieve better precision and better welding effect;
4. All cylinders are equipped with safety valves. In the event of power failure, high-pressure hose rupture, burst, etc., it can be automatically locked to prevent the cylinder/fuel tank from falling.
