Recyclable mining bolt(factory)
The lever body part can be recycled to reduce costs,This is our patent product
Installation method
1.Optional. Seam situation ø42, ø43, ø44 drill drilling drilling depth appropriate to the length of the metal rod can also be adjusted according to the situation hole depth.
2.The S = 3 the block trap into the threaded end of the metal rod with a retaining ring points, penetrate plastic expansion sleeve and then screwed into the plastic cone (cone Note nut screwed into the head of the metal rod thread 2-3 buckle expansion sets are not inflation open appropriate), the last end of the penetration of wood pad, metal tray, screw nut, the rod is pushed to the bottom of the borehole, fastened to the need to maintain a distance of 1-2 cm between the nut and the tray, so that the expansion sets inflation opened.
3.The assembled complete bolt penetration has been drilled and clean up clean drilling push in the end, with bolt rig with metal rod connected sets connected the the top tight metal rod and push hard Roofbolter, the rotation rig to stop drilling rig rotating action is appropriate. So immediately can make the the expansion sets swelling, completed the initial anchor. Tighten the nut again, and maximum torque is 100-120Nm. So as to reach the overall anchoring to complete the installation of the anchor.
The recovery of the metal rod
Remove the fastening nut with a wrench, then screw the metal rod body and tail, reverse screwing the metal rod from the adhesive sets, remove the tray, to recover metal rod and push the plate.
Storage, routine maintenance
Storage must be clean, dry, ventilation, maintaining the temperature of -3 to 40 ° C, 10cm high off the ground.Stacking height of 5 layers, avoid sunlight.Composite material portion non external impact to affect their physical properties such as crack, fracture, the metal rod to be vertically or horizontally, but must be fully in contact on the horizontal bracket or pad and prevent it from bending effects installation.
