在双线索道凹陷侧型设计中,承载索在支架上的最小折角(以下称空索角),其数值为负,当有载情况下,承载索在支架上的弯挠角为正值的设计,称为负角设计法.实际生产中,索道运转均处于均荷载条件下运行,承载索是在有荷载作用下工作的,因此,凹陷地形的负角设计法更显得有实际意 In the lateral design of two-lane cableway depression, the minimum bending angle of the supporting cable on the bracket (hereinafter referred to as the empty cable angle) is negative, and the bending angle of the supporting cable on the bracket is positive when the cable is loaded Design, known as the negative angle design method.In actual production, the cableway are running under average load conditions, the load cable is under the action of a load, therefore, the negative angle of the concave terrain design method even more practical
