| Abstract: | To expound the mechanism of wire rope structure extension.The advantges and disadvantages between continuous and intermittence pretension are compared.The property characteristics of the intermittence wire rope pretension equipment made at home are introduced.The production control requirements of wire rope needing pretension are put forward.The structure extension of wire rope is examined practically,and the result shows that the total extension of the 6×19+FC-37-1 670 MPa wire rope is 0.858% when it is pretensioned with 441 kN force,and the structure extension can be eliminated after extension,which can meet the practical use. |
