Protective measures for high-voltage lines of tower cranes?

The crane arm of Building A 1# in this project does not meet the safe distance from the high-voltage line. According to the requirements of electric power bureau, necessary protective facilities must be set up to ensure construction safety.

According to the requirements of electric power bureau, the erection scheme of protective facilities is as follows:

1, the protective frame is not less than 4m away from the high-voltage line, steel pipe double-row scaffolding is used below the high-voltage line, and bamboo and wood are used above the high-voltage line. The height exceeds the upper high-voltage line by not less than 4m. Protective frame should be firm and stable, with wind resistance.

2. Scaffolding interval 1.8m, vertical distance 1.8m, crossbar interval 1.8m, and the top of steel pipe scaffold shall not exceed the minimum high-voltage line. Scaffolding should be set with scissors and transverse braces. And set up 2-3 landing shots in the south. The throwing bracket must be firmly connected with the ground.

3, steel pipe scaffold erection to the bottom of the high voltage line, with bamboo frame erection. Protective frame erection layout as shown in the figure.
