Hydraulic jacking system
Hydraulic Lifting System (HLS-A)
The tank hydraulic lifting system is the special process engineering equipment for the steel storage tank inverted welding and storage tank independently developed by Nanjing Auto Electric Co., Ltd., which has accumulated many years of design experience and combined with the actual on-site use of customers. The device is advanced in technology and innovatively uses advanced modular design concepts. It is easy to install, simple to operate and reliable in quality when used on the engineering site.In practical application, it can also be used to adjust the jacking height independently (single group or single unit), and can also be used for centralized control of multiple groups.It is suitable for welding of steel small, medium and large tank inversion process.This series of tank hydraulic lifting equipment for the "one drag five" module.Namely: 1 hydraulic pump station, connected to 5 hydraulic cylinders, controlled by two control cabinets.In engineering application, multiple modules are determined according to the lifting load, and the hydraulic cylinder is evenly distributed in the tank for installation.It avoids the disadvantages of too much tubing and too many oil leakage points caused by traditional centralized oil supply, so as to ensure the lowest environmental pollution and improve the welding quality. It is easy to operate, safe and stable when the tank is lifted, and has good synchronization effect. It can cross work with the tank automatic welding machine.
This type of equipment lifting equipment for the single-acting two-stage hydraulic cylinder (hydraulic jack), used for vertical take-off and landing work, return trip requires external force or weight return.
This complete set of hydraulic lifting device for storage tank is compact in structure, safe and stable, easy to operate, adjustable in load, quick in installation and high in synchronization accuracy.The equipment is modular design,and the compatibility between the modules is good, can meet the different sizes of steel tank inverted process construction, no complex auxiliary pillar, can greatly save the customer's tooling cost.
