Before the card is mainly used for initial tensioning jack and a single anchor tension Anhui 80 tons jack stroke 500, ordinary feedthrough jack main anchor for the group overall tension. When installing anchors and jack jack stroke 300 Hebei 80 tons of straight tendons, should make the line of action of the tensile force and channel centerline coincide with each other in the tensioning process; curve tendons, should be the role of tensile force the end of the center line and pore tangents coincide with each other. Tension anchor tendons pass through from work, limit board, jack in the middle. Tensioning tendons order should meet the design requirements. RSM thin jack main series, complete special tonnage. Light weight, large tonnage, mobile and flexible. Fixed mounting holes make it easy, so the paint surface corrosion-resistant.
