Today safety rope of a wide variety, style a variety, then grasp certain certain methods to buy and choose safety rope is very useful, today I lead the big guys to master the following how to choose to fit the safety rope.
First of all, we have to grasp the basic characteristics of certain security rope. For example.
① webbing type security rope should choose high toughness, high strength fiber silk line and other materials, such as nylon, polyester, polymer, etc..
② fiber rope type security rope if the rope is multi-stranded rope, the number of strands should not be less than 3 strands.
③ wire rope type security rope should be made of high strength steel wire twisting, and twisting system is proportional, close, not loose; chain type security rope should reach the requirements of Gb/T20946.
Second, take into account the performance parameters of the security rope.
For the different material safety rope, in a variety of places below have must reach the performance parameters.
en standard requirements.
1. the total length of the safety rope which is the connecting part can not exceed 2m, in which the buffer and other accessories are included.
2. safety rope without buffer can not be used as a fall brake. 3.
3. webbing type, fiber type safety rope of the minimum static damage tensile strength of 22kN, metal material type safety rope of the minimum static damage tensile strength of 15kN.
And the national standard about static damage tensile strength in the en standard based on the different work carried out the classification.
① The work with the security rope and the area limited with the security rope to a variety of security rope requirements must be in 15kN static tension below to ensure no tear and breakage.
②Fall suspension security rope is a clear material different from the static tension value.
③ webbing and fiber rope safety rope requirements in 22kN static tension below to ensure that no tear and breakage.
④ wire rope type and chain type safety rope requirement is 15kN.
Because the textile material is more easily damaged than the metal material, so used as a fall suspension of webbing type, fiber type safety rope than wire rope type, chain type safety rope must be very large test test force.
Other, in the purchase of security rope, it is recommended that you should purchase a well-known brand.
The third step, watch the outer light of the security rope
In the safety rope’s outer light place, oneself precisely to use the visual side to try to test the test. Webbing type, fiber type safety rope can not have cut and tear, can not have line needle loose off, can not be due to chemical corrosion, can not change color and so on. Wire rope type, chain type safety rope can not have fatigue scratch, can not have rust traces.
In addition, pay special attention to the safety rope certain national mark. Reach this requirement finally, one can make the selection.
