Minimum mandreldiameter for bends, hooks and loops (see Figure 8.1)
弯曲处的最小心轴直径，鱼钩和圆环形（见图8.1。

In order to avoid damage to the reinforcement the diameter to which the bar is bent (Mandreldiameter) should not be less than.
为了避免损坏钢筋，钢筋最大弯曲处的直径(芯轴直径)最小应不低于。

By test and analysis, the direct reasons leading to failures are the defaults in designing coiler mandreldiameter change and controlling hydraulic system program but not the system parts themselves.
