Spin-Lock Rock Anchor Case Histories:
Radio Tower Guy Anchor, Branson MO

Unique engineering solutions were standard practice for a troublesome guy anchor on a US Dept. of Energy Radio Tower near Table Rock Dam, just outside of Branson, MO. The engineering and project management responsibilities were handled by Houston's Gem Engineering. Normal guy line anchoring was uneconomical due to severe excavation costs associated with digging a deadman anchor capable of 110 kips. Tahsin Gupinar and David Glasco of Gem engineering chose Williams' 2" Dia. Hollow-Core Rock bolt for their anchor solution. Williams' Spin-Lock anchors can be utilized with a hollow bar for superior grout performance and can be pre-stressed to the design load of the anchor. By pre-stressing the anchor the bolt will resist cyclic loading associated with wind loads, enabling the anchor to resist steel fatigue

Main Reason They Chose Williams
