- Tank jacking system. The tank jacking equipment we developed is different from the traditional jacking system. Traditional jacking system just for manual welding, in china more and more tank project have adapted automatic welding way to erect the tank, our innovated jacking system can fit for this development to match with our automatic welding machine to do both inside and outside tank welding automatically. Please refer to the photos from our project site (another appendix). And we also developed our jacking system function in order to be suitable for several diameter tanks.
The traditional jacking equipment is one general large scale hydraulic pump connecting to all cylinders in one tank,and the jacking carriage climbing along the column, which is very slow. To jack up one course of shell, it needs aournd 1.5 hour-2 hours. NAE’s innovated jacking system adopt single small scale of hydraulic pump for each module with 5 jacking cylinder, and then all the pumps in one tank connect to one general control, which can realize high efficient jacking solution with sychronization. To jacking up one course of shell, it only needs 20 mins -25mins. We call the one smaller pump adding five cylinders as one jacking module. Every module could connect with each other flexibly. The max capacity of one module is 100-125 tons; the duty capacity of one module is 72-90 tons.
