1. Safety Inspection Before Operation
Before adjustment, ensure the equipment is off or powered off to prevent accidental start-up and potential danger.
Inspect all guy cables for broken strands, rust, deformation, or loosening. Replace or repair any problematic cables before adjusting the tension.
2. Ensure the Tower is Vertical and Stable
Use a level or plumb line to check the tower's verticality. The direction of tilt will guide the adjustment priority.
The working surface must be firm and level. Avoid operating on soft, sloping, or waterlogged areas to prevent ground stakes from being pulled out and causing instability.
3. Diagonal Synchronous Adjustment to Avoid Unilateral Stress
Adjust both guy cables diagonally simultaneously (e.g., northeast-southwest, northwest-southeast) to prevent the tower from twisting or deforming due to excessive stress on one side.
When adjusting, use a wrench to slowly rotate the turnbuckle. Tighten clockwise to increase tension and loosen counterclockwise. The movement should be even and gradual.
4. Measure Tension Using Professional Tools
Use a tension meter to measure the tension of each guy wire, ensuring the tension difference between wires does not exceed 10% to guarantee balanced overall stress.
Refer to the manufacturer's recommended initial tension range (usually 300-500N). Under special operating conditions, this can be increased to 1.2 times.
5. Anti-Loosening Treatment and Verticality Check
After adjustment, immediately tighten the anti-loosening nuts on the turnbuckles to prevent tension from loosening due to vibration during equipment operation.
Recheck that the tower body has returned to verticality. Make minor adjustments if necessary to ensure structural stability.
6. Additional Precautions in Special Environments
After extreme weather events such as strong winds (above level 6), heavy rain, or blizzards, an immediate inspection and readjustment of the tension is necessary.
For long-term operation on high-frequency vibration or soft ground, it is recommended to shorten the inspection cycle to once a month.
7. Record and Traceability Management
A maintenance record form should be filled out after each adjustment, including tension value, environmental conditions, operator, and date, to facilitate subsequent traceability and accountability management.
