@jingjingde001: Chain hoists or hydraulic jacking — which is better for tank erection? When it comes to the inverted erection method for large vertical steel storage tanks, both systems have their place. Chain hoists may suit certain smaller or simpler projects, while hydraulic jacking systems can offer better coordinated lifting for large tanks when properly engineered. The right choice depends on tank size, lifting load, site conditions, safety controls and project budget. For large storage tank construction, floating roof tanks, fixed roof tanks and oil & gas projects, which lifting method would you choose? #StorageTank #TankErection #HydraulicJacking #OilAndGas #TankConstruction
