3. Ways of Application
1) It is used together with 50MPa oil pump. If the stressing tonnage is low, it can aslobe used together with 63 MPa oil pump.
2) It can be used together with limit plate or arm-brace. Put the limit plate in front of the jack.
3) The loose wedge cover can be adjusted by changing the size of expansion of the internal daimeter of thetool wedge which is suitable for the strand to pass through.
4) When stressing, push the limit plate and jack together to the tool anchorage, then it can be stressed with oil supplied by stressing oil.
5) When exiting the jack, the oil will be supplied by the return oil; the tool anchorage will will be opened automatically. At this time, the jack can exit or stress.
ATTENTION: the return oil pressure can't be over 25 MPa.
6) Replace the limit plate with the arm-brace, repeat the above stressing process, then exit the wedge in the working anchorage to eliminate the prestressing force.
1)Whwn stressing,calibrate systematically the jack, pressure meter and the oil pump.
2) It is suggested to use HM46 anti-wear hydraulic oil in the winter, HM32 anti-wear hydraulic oil in summer for the jack. The oil should be kept clean and changed regularly.
3) When stressing, the jack should work within the stroke. It is forbidden to exceed the stroke.
4) After stressing, the the oil mouth cover should be sealed and kept safely.
5) It is not suggested to dismantle the jack; however, if it is necessary to change the oil seal or to pepair, the oil mouth should be dismantleed. If necessary, it should be sent back to the manufacturer to repair.
