Wire rope sling is commonly used in dangerous working environment, so the wire rope sling testing is very important, daily to sling much for inspection maintenance, not be installed on whether regardless, it's easy to cause injury.
From fine twined measurement for diameter wire rope sling available soft white paper bag in the wire rope sling twist into. Wire rope sling out with a pencil in the trace of the shares, then use the scale of the precision measuring tools for fine twined delimit from measurement; A thick specifications of wire rope sling, directly in the wire rope sling to create symbols of measure and measure the length of the period for 5 from twisting, take its uniform value as a measurement results.
Both parties through consultation by the supply and demand, measure should be in no tension cases in wire rope sling with parts of the straight line. Maintenance content is mainly to the wire rope sling appearance, twisting quality system, internal function (especially mechanical function) quality appraisal. China wire rope sling delimit scale. Wire rope sling don't measured the whole rope breakage tension, according to wire break tension total supply, wire rope sling the sum total of the tension that is break the steel wire breakage of tension. Wire rope sling appearance appearance examination content including appearance the thickness of the fat, average sex, color, wire rope sling aperture size, cordless strands of loose, wire core exposed phenomenon, and presence of broken wire, wire cross, bend, damage, and other phenomena and packaging quality inspection.
Mechanical function tests wire rope wire rope mechanical function tests including the whole rope test and open strands of test. Samples are in the good wire rope sling a twist in the clips. The whole rope breakage tension test is tension test pilot of both ends with wire rope sling with the different specifications different fixed fixture application, make fixture can firmly to clip live specimens, will force is applied to the average of the shares.
Don't loose wire rope sling with sexual check the don't loose function should solve wire rope sling check at the end of the tie of the line. Tie line after unlock if stocks and shares in the free state of steel wire not change of fine twined state, not loose wire rope sling with sexual check the don't loose function should solve wire rope sling check at the end of the tie of the line. Tie line after unlock if stocks and shares in the free state of steel wire don't change twisting system state. Not occur spontaneously loose tendency, the wire rope sling is not loose for the wire rope sling appearance and quality check system of twisting generally do not use optical instruments and check with the naked eye, wire rope sling twisting system parameters of measuring tools are defined by scale for measurement.
Diameter measurement wire rope sling diameter with appropriate width mouth clamp with vernier caliper measure, the diameter of this wire rope sling diameter measurement with a proper width clamp mouth vernier caliper for measurement. Measure the diameter of wire rope sling inscribed circle as wire rope sling with the actual diameter. Fine twined in wire rope sling from measure of twisting process and measure in line pressing die and traction round wire rope between sling a long. For wire rope sling nominal tensile strength, MPaK ` for a specified structure wire rope sling minimum breakage tension coefficient. But in the process of making fine twined measure, also can intercept sample measure, are apart from at least 1 m two different direction of the section take 4 a measure point, each point of the tested value, to take even value. Also available in wire rope sling end unlock the corresponding two strands of about two twisting long distance, when the two strands to be twisted wire rope sling to, steel wire in stock hold in situ, shares in the wire rope sling should also came through in a recovery, this case, wire rope sling is not loose for maintenance result is the basis for the product is qualified judgment. Wire rope sling minimum breakage tension should comply with the scale and press the type defined calculation for the wire rope sling minimum breakage tension, kNd for wire rope sling nominal diameter, mmR
The maintenance of inner quality in the laboratory. The appearance of the maintenance of quality and fine twined in commonly produce the wire rope sling manufacturing process.
General staff are using certain means and methods of wire rope sling quality, characteristic and so on each index of detection. Wire rope sling produce of fine twined in the process of system and twist into later. Some special wire rope sling should be tired test, rubber attached function tests, straightness test, etc. The whole rope breakage tension test of wire rope sling the whole rope breakage tension wire rope sling is important mechanical function index. Twisting quality system and fine twined parameters including the inspection system from the wire rope sling with twisting and the diameter of the measurement and don't loose sex is checked.
In order to guarantee the quality of wire rope sling, the whole rope breakage tension test of wire rope sling the whole rope breakage tension wire rope sling is important mechanical function index. Twisting quality system and fine twined parameters including the inspection system from the wire rope sling with twisting and the diameter of the measurement and don't loose sex is checked. This is our workers and firms in order to guarantee the quality of wire rope sling. In addition to scale to wire rope sling overhaul the outside, also according to technical process and manufacture process card to produce the whole process of the process monitoring and quality inspection.
Wire rope sling down stocks of wire rope sling test the single wire, respectively, bend, pull over and over again 360 degrees turn test, everyone can you know wire rope sling down stocks of wire rope sling test the single wire, respectively, bend, pull over and over again 360 degrees turn test. Galvanizing steel wire coating thickness, soundness to average sex test; The above tests were all in accordance with corresponding national scale; Test results should comply with the wire rope sling scale demarcated index. The triangle strands of wire rope sling (see alien strands of wire rope sling) diameter measurement is measured the height of the cross section size.
Steel wire ropes with use correct is important, but checking and maintenance, etc also important, these work not only influence the safety of the operator, still affect the wire rope sling using life.
