Technological Breakthrough: From “Passive Protection” to “Active Safeguarding”

Traditional safety harnesses exhibit significant shortcomings during power tower operations: frequent unhooking is required during climbing, movement is restricted during tasks, and impact forces during a fall may cause secondary injuries. The new fall arrest device employs a “dual-hook alternating protection” design. Operators simply secure the main hook to the tower’s main structure, allowing the secondary hook to move synchronously, achieving “uninterrupted protection throughout the entire process.” The device also features a shock absorber that dissipates fall impact forces, reducing the risk of injury. Data from the National Energy Administration indicates this technology has been piloted in 12 provinces nationwide, cumulatively reducing high-altitude fall accidents by over 80%.

Application Scenarios: Covering the Entire Work Process

The device is suitable for scenarios such as climbing power transmission towers, crossarm operations, and conductor maintenance. For climbing, workers secure the main hook to the tower structure, and the secondary hook automatically switches positions with the body, eliminating manual operation. During crossarm work, the device can be fixed at the crossarm end to provide full-range protection. An employee from Shaoxing Power Supply Company of State Grid Zhejiang Electric Power Co., Ltd. stated: ” After using it, climbing efficiency increased by 30%, operational range doubled, and safety confidence significantly improved.”

Industry Impact: Driving Safety Standard Upgrades

The National Energy Administration has incorporated fall arrest devices into the “Electric Power Safety Work Procedures,” mandating standardized fall protection equipment for new towers. Experts note this technology is poised to become the “standard configuration” for high-altitude work in the power sector, with potential future expansion into construction and telecommunications fields. With intelligent development, future devices may integrate sensors and IoT technology to enable real-time monitoring and early warning.

The widespread adoption of fall arrest devices on power transmission towers signifies a shift in China’s high-altitude work safety from “reactive measures” to “proactive prevention.” This innovation not only safeguards lives but also lays a solid safety foundation for the high-quality development of the power industry.
