Elevator wire rope Technical Reference: 5241 Elevator wire rope should be pre-deformation and deformation after 5242 elevator ropes twisting uniform deformation of loose wire strands and other irregularities cord size should have sufficient support so that the package twist the shares uniformly twisting in case of no-load, open-book elevator ropes shall wavy 5243 elevator wire rope does not allow loose 5244 wire connector application of the butt welded wire diameter not greater than 040mm can also be used to plug the 525 pre-tensioning load limit, such as supply elevator rope according to the demand side requirements required by the Pre-tensioned to avoid elevator rope damage in the pre-tensioning process process applied the maximum load should not exceed elevator rope minimum breaking tension of 55% Note loads can be static or dynamic way carried 526 elevator wire rope lubricant demand side, such as elevator wire rope coated with lubricant other requirements by the supply and demand of the agreement and 527 steel wire zinc coating weight specified in the contract can not be used in the lubrication of lubricating last together all strands rope stranding process should be consistent with GB / T 8919 - 1996 in Class B galvanized steel wire requires 528 mechanical properties of 5281 elevator wire rope minimum breaking force the elevator wire rope minimum breaking force should be consistent with the provisions of the normative Appendix A Appendix Table A.1 to A.5 5282 elevator stock split the wire in the wire rope testing a tensile strength of at least 95% of the test wire should be consistent with the low value wire tensile strength tensile strength range specified in the standards listed in Table 3 to reduce the value shall not be greater than 50 MPa demand side as special requirements should be executed agreement between
