Spin-Lock Rock Anchors
Spin-Lock Rock AnchorsWilliams Spin-Lock anchors were first used in the 1950’s for rock/roof bolting in projects such as NORAD and Australia’s SnowyMountain power facility. Since then many engineers, contractors and owners have seen the advantages of the Spin-Locks on dams, locks, water/waste treatment facilities and many other large scale civil projects. Williams Spin-Lock anchors provide the advantage of immediate anchorage for pre-stressing and require shorter embedments than traditional grout bond anchor systems.
The Spin-Lock has been job-proven, time and time again to meet all bolting requirements in any strata which can be bolted.
To comply with the need for bolts which will satisfactorily anchor a broad range of variable rock formations, Williams has developed a complete family of rock bolts with a simple and efficient system of installation. Williams offers a complete line of rental equipment for installing, testing and grouting of Spin-Lock anchors.
Before proceeding with your next project, consult with a design agency familiar with Williams Rock Bolting. Williams would be pleased to recommend an ideal system for you.
