SURELOCK® spin anchors are flexible high tensile steel strands of specific lengths, resin anchored inside a drilled hole with an innovative locking-off unit called the ‘SURELOCK® swivel barrel’ at the collar. The advantages of utilising this locking-off device is that once the required prestressed load is achieved, the shear ring shears on the barrel into a positive visual indicator with an audible knock.
SURELOCK® spin anchors are made to requirements as specified by the end user. These anchors are designed to give immediate support and are normally post-grouted after being pre-stressed.
These anchors are easily installed using trained support installation crews
The cable anchors are manufactured to the required specifications of the customer e.g. the cut length of the strand, specified load at which the shear ring activates, number of bulbs
All spin anchors are tensioned to the required loads as specified by the customer, with hydraulic equipment approved by the supplier
The spin anchors can be installed in incompetent rock
All spin anchors may be grouted either before or after pre-stressing the anchors.
Duraset provide ‘on the job’ training and certificates are presented to individuals who successfully complete the anchor training.
