Article 3.2.1 The selection of load-bearing ropes shall meet the following requirements: 1. The load-bearing rope shall be a sealed steel wire rope, and its nominal tensile strength shall not be less than 1170MPa.
2. The initial tension at the tightening end of the load-bearing rope shall be calculated as follows: 608m\, a bottom-dump truck should be selected. Fourth, under the same transportation capacity conditions, a truck with larger load capacity and volume should be selected.
Fifth, the effective volume utilization coefficient of a tipping truck should be 1.0 when transporting non-adhesive materials and 0.8~0.9 when transporting adhesive materials; Sixth, the ratio of the upper width of the cargo box to the maximum block size of the transported material should not be less than 8 when a rotary loader is used, not less than 4 when a gravity loading device is used, and not less than 2.5 when a forced loading device is used. The design of the truck in case 3.1.2 should meet the following requirements: 1. The load capacity of the truck should be 1.0, 2.0 and 3.2t, and the volume of the truck should be 0.5, 0.63, 0.8, 1.0, 1.25.1.6, 2.0 and 2.5m2.
3. The running speed of the truck should be 1.6, 2.0, 2.5, 2.8, 3, 15, 3.6 and 4.0 m/s.
4. The length of the hanger should be checked according to the condition that the truck shall not touch any part of the bracket when the truck swings 20% longitudinally and transversely on the bracket with the largest inclination angle of the load-bearing cable.
The cargo box should have a removable locking device. 6. The wheels should be equipped with cast nylon wheel linings or other soft wear-resistant wheel linings. Article 3.1.3 For cableways with automatic cornering or automatic relocation stations, the maximum running speed of the truck should comply with the provisions of Table 3.1.3. Maximum running speed of the truck when the automatic cornering or automatic relocation is set The curvature radius of the horizontal ferry group (m)
Appropriate reversing wheel diameter (m)
