After the wire is tense enough, tightening the wire rope clamps will help ensure the structure stays at optimal tension levels. To tighten guy wires on an erected structure, professionals should attach the come-along to a wire-pulling grip and use this mechanical combination to draw in slack. To keep each wire at optimal tension, check and adjust them as needed throughout the process until the structure is entirely in position. Guy wires secure the gin pole to the ground, and raising or lowering the gin pole raises and lowers the structure it carries.Īs the team raises or lowers the structure, some of the gin pole's anchoring guy wires will tighten, while others will loosen. A gin pole is a common tool professionals use to raise and lower guy wire structures. When ready to begin the installation, first confirm all wires and hardware are secure on the structure the crew is lifting. Harsh weather can make guy wire installation difficult and cause safety hazards. Weather: Only install guy wires on dry days without wind when there's no chance of rain or electrical storms.They should also wear proper personal protection equipment, including hardhats, rubber-soled boots and protective sleeves. When working in the vicinity of any electrical wires, installers should always note any live wires that could pose a safety risk. Safety: Crew safety should be everyone's top priority in any situations involving tensioned guy wires.Find a professional you trust to follow these parameters: Installers use them to determine when a guy wire reaches its target load.Īs with any guy wire procedures, professionals should follow all proper steps and safety procedures. Dynamometer: Dynamometers measure guy wire tension with built-in analog load cells or digital scales.Come-along: A come-along is a hand-operated wire lifting device that helps adjust guy wire tension by pulling wire in or letting it out.Wire-pulling grips: Wire-pulling grips create temporary tension on guy wires until the team tightens or loosens them to ideal levels.End sleeves: When tensioning guy wire with big grip dead ends, end sleeves attach on the ends of the wires to prevent unraveling while the wires are at high tension.You'll also need wire rope clips, which are specialized fittings that clamp the loose ends of the guy wires to secure eye loops. Big grip dead ends, for instance, are one-time use guy wire tensioners you can use during initial wire installation and reapply during new installations and re-tensioning. Guy assembly: The guy wire and all attachment hardware make up the general guy assembly.Key guy wire tensioning equipment includes: Once you have your guy wire, you'll need additional hardware to attach it to your structure with the correct tension. If you want to learn how to tension guy wire, your first step is to gather the correct equipment for safe maintenance. Routinely check on your guy wires' tensions to ensure your commercial structures are as stable as possible, and adjust the tension as needed.Įquipment Needed to Tension Guy Wires Safely Loose guy wires also raise the risk of mechanical failure and fatigue damage and can even cause structural insecurities.įor best tension results, only use high-quality products, and always enlist the help of a professional. Wires that are too loose can gallop, meaning they'll move with the wind and other weather events, which can become an issue if they contact nearby objects or if the excessive movement places stress on the structure's operating components. High tension can also make the wires vibrate during heavy wind or earthquakes, inducing excessive wear and tear on wire and structure components. Wires that are too tight may cause compression failure in a structure, causing it to buckle and even collapse from too much pressure. Since guy wires stabilize structures and transfer their weight, installing them at the proper tension is crucial. The entire wire setup creates a diagonal line that helps secure the structure from the foundation all the way up. One end of the wire connects to a high point on the structure, while the other anchors into the ground. Guy wires transfer some of a tall structure's weight to the ground off to the side through their stress.
