The meanings of the numbers in the wire rope 6×37+1-21.5:
- 6 means that the wire rope is a 6-strand wire rope;
- 37 means that there are 37 steel wires in each steel strand, and they are point-contact strands. The steel wires are arranged according to 1 (center) + 6 (inner layer) + 12 (second outer layer) + 18 (outermost layer); 1 means fiber Rope core; 21.5 means that the nominal diameter of the wire rope is 21.5mm.
- The meaning of each number of 6*19: 6 means that the wire rope is composed of 6 steel strands; 19 means that there are 19 steel wires in each steel strand, and the arrangement of the wires in the steel strand is 1+6+12, which is a point contact wire rope, twisted The stranding process requires 2 twists.
- The meaning of each number of 6*37: 6 means that the steel wire rope is composed of 6 steel strands; 37 means that there are 37 steel wires in each steel strand, and the arrangement of the steel wires in the steel strand is 1+6+12+18, which is a point contact wire rope , The twisting process requires 3 twists.
- The meaning of each number of 6*61: 6 means that the steel wire rope is composed of 6 steel strands; 61 means that there are 61 steel wires in each steel strand, and the arrangement of the steel wires in the steel strand is 1+6+12+18+24, which belongs to the point When contacting the steel wire rope, the twisting process requires 4 twists.
What does parameters 6*37+1-65.0-170 mean?
- 6 means that the outermost layer of the steel wire rope is composed of 6 steel strands, namely 6-strand steel wire rope;
- 37 represents the structure and the number of steel wires in the steel strand, and the steel strand structure is 1+6+12+18=37 steel wires;
- 1 represents the core of steel wire rope;
- 65.0 means that the nominal diameter of the wire rope is 65.0mm;
- 170 indicates that the nominal tensile strength of the wire rope is 170kg;
The wire rope implementation standard is GB1102-1974 wire rope standard, this standard has been eliminated, the effective standard is GB/T 20118-2006 general purpose wire rope;
In crane operations, the commonly used wire ropes are 6×37, 6×19 and other models. Enterprises should pay attention to the maintenance of the wire ropes during the use of cranes.
