Post tension cable bolts has three forms according the requirements : PTCB, PTYCB-I, PTYCB-II

TECHNICAL MERITS :
  • Birdcage is for better resin mixing, centralizing the cable in the drill hole, ensuring the pull load
  • The birdcages are made to fit the drill hole size
  • PTCB is the common post tension cable bolts
  • PTYCB-I is a yieldable Cable bolts. It is widely used in impact pressure and large deformation conditions
  • PTYCB-II is ayieldable and load indicating cable bolts. It is widely used in impact pressure and large deformation conditions
