Hydraulic Tank Jacking System:
Tank Jacking system uses dual-stage hydraulic cylinders to lift and horizontally build storage tanks from the top down (the return trip needs external force or dead load for returning). This enables the horizontal and vertical welding of tank shell can be conducted on the ground efficiently and safely, cooperated with submerged-arc automatic girth welding machines (AGW) and vertical welding machines (EGW).
Hydraulic tank jacking system with the flexibility to lift storage tanks of different capacities and weights that are compatible to various manual or automatic welding methods adopted by tank contractors across the globe.
We can handle the largest tank projects and we can do it safety with maximum saving of time.
Our jacks are mounted securely on the floor and using the massive cylinder as a beam, will support the structure even in higher wind loads.
Each HLD jacking module has it’s own hydraulic pump and reservoir. They are linked to a central control that commands all aspects of the jacking operation.
Each standard HLD jacking module with 2 cylinders is capable of lifting 50,000 kg, which allows fewer jacks to raise a tank, it is designed with a large clearance from the tank shell that gives the workers extra room to quickly insert plates.
In operation, the cylinders are attached to the wall, the control loads the jack manually, or automatously via the addition of a PLC unit, then lift the structure holding tolerance within 2mm.
- High quality, dual-stage hydraulic cylinders to lift and horizontally build storage tanks from the top down (the return trip needs external force or dead load for returning). This enables the horizontal and vertical welding of tank shell can be conducted on the ground efficiently and safely, cooperated with submerged-arc automatic girth welding machines (AGW) and vertical welding machines (EGW).
- Specifications:
- Capacity of storage tank jacking module is 25t
- If appropriate quantity of modules are equipped, their storage jacking capacity can be up to 1500t
- “One for five” oil supply method: every set of hydraulic power units are connected to 5 sets of hydraulic cylinders, avoiding the disadvantages of traditional centralized oil supply (too many oil pipes and too many oil leakage points, ensuring to minimize the environmental pollution)
- Applications:
- Inverse installation construction of petrochemical vertical cylinder type steel tank (hydraulic lifting method)
- Steel liner inverse installation construction of power plant chimney
- Vertical hoisting and lifting of super large objects
- Main components
- 5X customized hydraulic cylinder
- Hydraulic power unit
- May supplement: centralized control operation box and power operation box

Choosing the Right Tank Jacking System
The right tank jacking equipment depends on your project’s specific requirements, not just on lifting capacity. Tank diameter, shell weight, site conditions, and the construction sequence all play a role in choosing the right system.
For contractors who build tanks of different sizes, a modular system can be a smart investment because it can often be reconfigured for future projects instead of being replaced.
It’s also important to consider how the lifting system will work with your automatic tank welding machine. Equipment that’s designed to operate together helps keep the job moving and reduces downtime between lifting and welding. Before you buy, take a close look at the supplier’s technical documentation and replacement parts program.

Frequently Asked Questions
How do I choose the correct lifting configuration?
Every project is different. The number of lifting modules depends on the tank diameter, over weight, and how the load will be distributed during construction. Sharing tank design drawings early helps determine the right configuration before fabrication begins.
Can a hydraulic jacking system be used on multiple projects?
In many cases, yes. Modular lifting systems can often be adjusted to accommodate different tank diameters, allowing contractors to use the same equipment on future projects rather than purchasing a new system each time.
Why should lifting equipment be compatible with welding equipment?
Using hydraulic tank-jacking equipment with an automatic tank-welding machine helps keep construction moving. Once a shell section has been lifted into position, welding can begin without unnecessary delays caused by incompatible equipment or extra setup time.
What information should I prepare before requesting a quote?
Have the tank diameter, estimated total weight, type of roof, project location, and construction schedule ready. These details allow the engineering team to recommend a system that best matches the project rather than relying on a standard configuration.
How can I keep the equipment operating reliably?
Routine inspections make a difference. Check hydraulic hoses, cylinders, fittings, and control components for wear before each project, and replace damaged parts before they affect production. Following the recommended maintenance schedule can also reduce unexpected downtime.
What support is available after purchase?
Technical support should continue after the equipment is delivered. Tank construction projects can change as work progresses, so access to replacement parts and current technical documentation helps crews keep work moving and address issues without lengthy delays.
