    • An anchoring device for use in a rock-crevice defined by a first rock wall and an opposing second rock wall. The anchoring device comprises an axle member having a longitudinal axis. A first cam is rotatable about the longitudinal axis of the axle member and contactable with the first rock wall with the first cam having a first side wall and a second side wall. A second cam is rotatable about the longitudinal axis of the axle member and contactable with the second rock wall with the second cam having a first side wall and a second side wall. The first side wall of the first cam is aligned with the first side wall of the second cam and the second side wall of the first cam is aligned with the second side wall of the second cam. Upon a first force being applied to the first cam by the first rock wall and a second force being applied to the second cam by the second rock wall in a direction generally toward the longitudinal axis, the axle member is free from any created moment.
    • 一种用于由第一岩壁和相对的第二岩壁限定的岩缝中的锚定装置。 锚固装置包括具有纵向轴线的轴构件。 第一凸轮可围绕轴构件的纵向轴线旋转并且可与第一岩壁接触,第一凸轮具有第一侧壁和第二侧壁。 第二凸轮可围绕轴构件的纵向轴线旋转并且可与第二岩壁接触,第二凸轮具有第一侧壁和第二侧壁。 第一凸轮的第一侧壁与第二凸轮的第一侧壁对准,并且第一凸轮的第二侧壁与第二凸轮的第二侧壁对准。 当第一力由第一岩壁施加到第一凸轮时,并且第二力由第二岩壁沿大致朝向纵向轴线的方向施加到第二凸轮时,轴构件没有任何产生的力矩。
