In the process of frame installation, pipe gallery installation, grid plate installation and pipeline construction, when there is no scaffolding work platform or inconvenient to install the work platform, life ropes (horizontal ropes, safety ropes) shall be set up for the operator to hang the seat belts. Pull the safety net below the work surface.

The horizontal rope should be made of wire rope with a diameter of not less than 12mm. When pulling the horizontal rope, the five-point seat belt and the corresponding labor protection products must be worn. There must be a temporary corridor when crossing the beam, and the guardian guards the ground. .

The height of the horizontal rope is determined according to the specific conditions. When the steel structure is used as the fixed point, the steel wire rope must be wound around the column for more than one turn, and the sharp edge of the column should be avoided to damage the horizontal rope, and the horizontal rope should be straightened. Not less than three saddle cards lock the wire rope head.

Safety net protection should be provided when working in a pipe gallery with a falling height of 4 meters or more.

The seat belt must be hung on a firm member above the construction work and should not be hung in a location with sharp edges and corners. There should be enough clearance under the seat belt hanging point. Seat belts should be low-hanging (system) low-use, and should not be used below the waist level.

Use and maintenance

1. To ensure safety, the activity clip should be fastened when worn, and should not be used at temperatures above 120 °C. Visual inspection is performed first every day, and it is found to be damaged and immediately stopped using.

2. The seat belt should be used with high hanging to prevent swinging collision. It is not allowed to tie the rope or directly hang on the safety rope. It should be hung on the connecting ring and should not be used when the body is under heavy load.

4. After one year of use of the seat belt, check the quantity by purchase. The fence is subjected to a static load test. The 225 kg pull is pulled for one minute. The seat belt is hung for impact test. The weight is 80 kg, and the free fall test is not broken. The batch can continue to be used. Do not use the sampled sample.
