EN 13796-2:2005 (E) 5 1 Scope This European Standard specifies the safety requirements applicable to carriers for cableway installations designed to carry persons. It is appli
27、cable to the various types of installations and takes into account their environment. This European Standard describes the requirements to be met when testing the slipping resistance of grips clamped on the haulage or carrying hauling rope of carriers of monocable or bicable aerial ropeways with fix
28、ed or detachable grips, covered by 7.4 of Part 1 of this standard; on the towing rope of ski-tows with fixed grips, covered by 7.6.2 of Part 1 of this standard. It does not apply to installations for the transportation of goods nor to inclined lifts. 2 Normative references The following referenced d

The test
33、shall be carried out by a laboratory certified according to EN ISO/IEC 17025. The test will make it possible to validate the field of use of the grip proposed by the manufacturer. 6 Parts to be tested The geometry and the materials of the test piece shall be identical to the series-produced componen
34、ts. Their production methods shall be equivalent. In particular, the test piece shall be galvanized if it is planned that the series-produced component will be. 7 Information to be provided by the manufacturer The manufacturer shall supply the following information and documents to the test laborato
35、ry: general description of the grip; production drawings of the grip; descriptions and explanations required to understand the above-mentioned drawings and the mode of operation of the grip; field of use of the grip, including F theo ; declaration of conformity certifying that the grip supplied for
36、the test corresponds to the operating manual specified in EN 13796-1. The test piece shall be identified by a mark. 8 Examination prior to the test The test laboratory shall verify by a visual examination that the test piece complies with the documentation supplied by the manufacturer. The procedure
37、 and the result of the examination shall be included in the test report. 9 Test requirements The test consists of subjecting a grip clamped on a rope to an increasing tensile force until it starts to slip, while recording the change in its resistance to slipping. whatever the field of use of the gri
38、p, the test shall be carried out on a parallel-lay galvanized rope. If the field of use of the grip specifies several nominal machining diameters for the jaws corresponding to as many nominal rope diameters, the test shall be carried out only on the largest diameter; EN 13796-2:2005 (E) 7 the rope s
39、hall be subjected to a tensile force corresponding to 1/6 of its breaking load; the grip shall be attached according to the conditions specified by the manufacturer; the equipment used to transmit the force shall allow controlled and gradual application; the equipment for measuring the slipping resi
40、stance force shall enable a continuous permanent record to be made of the applied force as a function of time; the tensile force on the grip shall be applied so that the resultant of the slipping force coincides with the axis of the rope; the force on the grip shall be applied progressively until sl
41、ipping starts and shall be maintained to cause a minimum slippage of at least 5 mm; the test shall be carried out 10 times. The total slipping length I gtotshall be at least: I gtot rope strands the of in number strands of pitch(m) ( 1 ) These tests may be carried out successively without opening th
42、e grip. 10 Slipping resistance force The slipping resistance force F labis equal to the mean of the maximum values F maxobtained in the 10 tests: F lab= 10 max F( 2 ) 11 Conclusion of the test 11.1 Evaluation of test results The test is regarded as satisfactory if F labis greater than F theoand no m
43、ovement of any wire making up the test rope is observed in the zone affected by the slipping of the grip. 11.2 Test report The procedures and results shall be included in a test report. The test report shall meet the requirements of EN ISO/IEC 17025. EN 13796-2:2005 (E) 8 Annex ZA (informative) Rela
