The patented Reactionless Cable Anchor (RT Cable Anchor) offers the convenience of a threaded cable installation with the performance and pre-stressing capacity of a barrel and wedge system. The flexible, high yield tendon makes the anchor ideal for use as primary or secondary support in confined installation spaces or where long installation lengths are required.
The self-activating expansion shell prevents the anchor from falling out of the hole during installation and provides full UTS support on insertion of the bolt, before pre-stressing or grouting is performed*. The patented reactionless tensioning system allows for rapid, single pass, hands-free and remote tensioning of the installed bolt from behind the supported line using the specialised tensioning socket. The lightweight, low maintenance tensioning socket uses no consumables and can be powered by a portable pneumatic-hydraulic power pack or can be driven off of alternative power sources such as drill rig hydraulics.
The anchor can be easily grouted to protect against corrosion and to provide full column load carrying capacity. The grouting system is compatible with common cable anchor grouts and offers one-way full column grout indication.
