The Guy-Lock™ patented solution was developed by Tower Engineering Solutions (TES), a Congruex company, as a way to combat guy anchor corrosion and as a method for adding tower capacity.
“We were concerned with the use of the traditional method of anchor corrosion detection — digging to the block, or down to the foundation. It requires extensive planning and can create an unsafe work environment, increase costs, and take a lot of time,” said Jaime Reyes, Vice President Operations, TES. “In most cases, if corrosion is suspected because of the age of the asset or it’s location in a highly corrosive environment, there is no need to excavate all the way to the block to confirm the suspicion. We have also reviewed sites where the digging to the block improperly has led to the failure of the guyed tower as the anchor failed in the digging process.”
The TES Guy-Lock™ method prevents the need to disconnect guy wires, dig to the block, or install a new anchorage point. This method can also eliminate the need for cathodic protection, resulting in savings up to 25 percent over traditional solutions, according to TES. “The solution not only avoids the risk of other methods, but it also saves the owner the cost of having to lease additional space for the install of another anchor point,” Reyes said.
The TES Guy-Lock™ is a shallow, uniquely shaped concrete structure. “By connecting the new anchor shaft steel to the existing anchor head plate, the work can be done without disconnecting the existing guy wires. All work can be completed safely on the ground by a civil crew, eliminating the need for a tower crew,” Reyes explained. “The TES Guy-Lock™ can be designed to match the capacity of the existing anchors or for additional capacity as needed.” Qualified contractors create a construction (rigging plan) per ANSI/ASSP A10.48 and the qualified engineers can review the plan per ANSI/TIA 322.
As tenants and extra wind loading are added to towers, costly structural reinforcement or complete drop and swaps can be avoided with the Guy-Lock™ solution. “The TES Guy-Lock™ solution continues to result in significant savings for our customers as a much safer approach to addressing guy-anchor corrosion and for increasing guy anchor capacity when needed,” Reyes said.
