Product Description Double Acting High Tonnage Hydraulic Cylinder Jack for Bridge1. Usage: It is mached with prestressed anchorage widely used in the construction of bridge and buildings, railwayand subway, water conservancy and hydropower engineering.2. It is suitable for the tension of group anchors with 1860-2000 sizes, Φ 15.24, Φ 12.7 strands.3. In some certain circumstance it can be used in the working of pushig, jacking and transforming and so on.4. Easy to use with reanosable price.5. Jack is used for prestressing worksFeatures:1. Using the new seals, to synchronous strengthen the seal-ability under great pressure.2. Using special alloy steel with heat treatment process, reducing the cylinder's expansion ratio in the tensioningprocess. So that the life of seals and sealing performance can be improved about 20%.3. In the tensioning the operating process, jacks is easily damaged under overpressure because of the jack-basedpullback clinder, so we added the overpressure valve on the jacks to pressure production. Meanwhile we improvedthe original of commonly used structure by wire disc and flanged disc, to make the bearing capacity for oil pressurestrengthen. So that enormously reduce the possibility of mechanical damage due to improper operation.In the word, the YDC series feed-through jacks' performance is improved, and widely used in pre-stressing andpoststressing construction.Notice: According to users' requirement, YDC through jack can be configuredPicture of post tension jackPicture of pre-tension(pre-stress) jackTechnology data of multi-strands tension hydraulic jack:Item/DimensionsNominalTensionRated OilPressurePullingStrokeArea ofTensioningPistonCenter holeDiameter MinimumWorkingSpaceThe ReservedLengthof StrandOverdimensionKNMpammmm2mmL(mm)E(mm)K(mm)outdiameter(mm)length(mm)YDC60605415011193087459.538770287YDC130130501602592308387739590295YDC2702706118544183088889415105315YDC650650501501301840860145380170288YDC110011005120019792801210184680217330YDC150015005020030257901210230680270330YDC2000200051200398201101296272723320360YDC2500250052200483811271306298728350360YDC3000300052200577271451322336736375380YDC3500350048200734351621322336745415395YDC4000400051200791681621324374745435395YDC4600460051200910281801350420750470410YDC5000500049200969972001340434745495410YDC55005500502001105061981350520800526498YDC6500650049200675442121350550850568538YDC9000900051200786182751400620900680603YDC1200012000512002313002751400620900780603Company Information:
