Features: SeparationHigh separation and light body.  Increase the separation amount and reduce the insertion depth of wedge block into the flange. At the same time of separation, prevent flange dislocation. FrictionNo friction, parallel, smooth movement, no flange damage. Portable, single person operation, suitable for narrow space and high altitude operation, reduce labor intensity. It is widely used, convenient, safe and efficient. The oil cylinder is made of aerospace high strength light alloy material, and the working head is made of special steel. It can provide 210kN slotting force. The system adopts German seal and aviation hydraulic oil. It can work reliably at - 30 ℃ ~ 55 ℃.
