Product description

The Anti-Spin Cable is an anchor utilising a self-activating expansion shell to allow instant pre-tensioning immediately upon installation prior to grouting.

 

The Anti-Spin Cable is installed using a semi-mechanised process to insert and then tension the cable to 25 to 35 kN. A unique anti-spin mechanism allows tensioning to be achieved without torque and energy being applied into the cable, which would otherwise reduce load bearing capacity. A load  indicator in the grout seat confirms that the correct pre-load had been achieved at  installation. The integrated grouting mechanism ensures the Anti-spin cable is fully encapsulated to maximize load transfer and corrosion protection.
