Product Name: Hydraulic Jack System/ Top to Bottom Tank Construction Machinery Condition: New Certification: ISO 9001:2000 Max Height: >400mm Power Source: Hydraulic Capacity (Load): 21-30T Structure: Hydraulic Jack Type: Hydraulic Jack Engineer Oversea Service Is Available: More Than 5 Meter Tank Trademark: WINCOO Transport Package: Container Specification: SGS, ISO9001, CE Origin: China HS Code: 8425421000 Product Description ★ ApplicationThe equipments are mainly used for vertical tank top to bottom construction.Also it can be used for mega work piece jacking or lifting.★ FeaturesThe system consists of hydraulic pump station, cylinders, steel wire, and strokes. Easy to installation and operation;The system utilizes PLC central control to handle lift. Each power pack is equipped with auxiliary balance device to guarantee the precision of simultaneously lifting.Hydraulic lift pump station has subsidiary manual control and central control two operation models. The cylinder can be adjusted to lift separately or to lift with several others as one group, and multi groups can also be integrated to lift reach better precision and better welding effect.All the cylinders are with safety valve. It can be automatically locked to avoid cylinder/ tank dropping even under situation of power off, high-pressure hose broken, burst. The cylinder is with one high pressure hose to avoid oil leaking that usually happen by the traditional multiple hoses. Cylinder will return to initial condition by itself weight.Stroke of Hydraulic cylinder is 2700mm, which can satisfy each annular shell one-step lift. Greatly reduce the time waste.Hydraulic cylinder basic height is 1910mm, which can match automatic girth welding machine to proceed internal girth seam welding.SNNameData1Maximum pressure20 MPa2 Maximum out-put force.250 kN3Maximum lifting height 2600 mm4Maximum stroke distance2700 mm5Cylinder lifting speed223 mm/min6Oil pump flow rate14.4 L/min7Motor rotating speed1440 r/min8Motor service voltage ~380 V9voltage of electromagnetic directional valve~220 V10Required temperature range-10~60 ºC
