Tank Jacking system

Hydraulic Tank Jacking system:

  • Tank jack up system leaflet 11.16.2022
  • EGW-V leaflet 10.27.2021
  • AGW-U leaflet 10.27.2021
  • Our Tank Jacking system consist of 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
  • Technical parameters
  • Model YT25-2700
