Correct use of safety ropes and seat belts

How to use seatbelts correctly during construction?

Seat belts are personal protective equipment for high-risk workers to prevent falling accidents and are widely regarded as life-saving belts by construction workers. The safety belt is made up of belts, ropes and metal fittings. The seat belts are collectively called safety belts.

The correct use of seat belts : In the absence of protective facilities on the high cliffs, steep slope construction, must be fastened seat belts. Seat belts should be high and low, taking care to prevent swing collisions. If the seatbelt is worn high, once it falls, it will increase the impact and bring danger. The length of the safety rope is limited to 1.5~2.0m, and the buffer should be added to the long rope with 3m or more. Do not use the rope knotted, nor use the hook directly on the safety rope. Use it on the connecting ring. The various components on the seat belt must not be arbitrarily removed, and should be checked once every 2 years or more. Suspended seat belts should be subjected to impact tests with a 100 kg weight for free fall test. If not, the safety belts can be used continuously. Frequently used ropes should always undergo visual inspections. When abnormalities are found, they should be scrapped in advance. Newly used seat belts must have a product inspection certificate and no proof of use.

The safety rope for aerial work should be flattened during use, and should not be distorted. The three-point lumbar seatbelt should be tied as low as possible, preferably on the hips, not on the waist; shoulder harnesses should not be placed under the arm and should be slung Chest.

How to use the horizontal safety rope correctly?

The hand-horizontal safety ropes are set at special places in high places, such as suspended steel beams, frame-linked beams, etc. After the crane is in place, the construction personnel must walk on it to prevent the fall of the person's balance of gravity.

There are the following aspects in the setting and use requirements for the hand-held horizontal safety rope :

1. The horizontal safety ropes for hand-holding should adopt 6*37+1 steel cords with plastic sheaths, whose technical performance should meet the requirements of GB11 “Circular Strand Wire Rope”, and have product production license and product ex-factory certificate.

2. The two ends of the steel wire rope should be fixed on a firm and reliable frame, and the winding on the frame should not be less than 2 turns. When contacting with the corners of the frame, it should be cushioned.

3, the end of the wire rope fixed connection should use a rope card (also called wire rope clamp), rope card pressure plate should be at the end of the long wire rope, the number of rope card should be not less than 3, the rope spacing should not be less than the diameter of the wire rope 6 Times; safety chuck installed about 500 mm from the last chuck, the rope should be released after a safe corner and then clamped with the master rope.

4. The fixed height of the wire rope should be 1.1-1.4m; a fixed support point should be set for every 2m interval; the arc-sag should be 10-30mm after the wire rope is fixed.

5, walking horizontal safety rope only as a high work under special circumstances, for the operator when walking the rope, is strictly prohibited for the use of a belt suspension point. Should always check whether the fixed end or the fixed point is loose, whether the steel wire rope has been damaged and corroded or broken.
