INSTAL® CC Tensionable Cable Bolt is manufactured using 0.6 or 0.7" cable with pre-set housing and wedge and 1-1/8" square drive nut. A threaded stiffener tube with attached shell is set on the cable at the housing end and resin mixing bulbs are incorporated at the opposite end. Bolt rotation engages the shell with the borehole and sets tension on the bolt.
Function
INSTAL CC Cable Bolt is used for primary and secondary support. The CC cable bolt is part of the INSTAL family of tensionable cable bolts and is the only tensionable system approved by MSHA as primary support. It is most commonly used when the primary system is supplemented with cable bolts in the normal bolting pattern. Using CC bolts, the normal primary support can be replaced and no additional secondary bolting is needed. The INSTAL CC Tensionable Cable Bolt is available in a fully grouted cable bolt configuration.
