1. the shock attenuation unit of an elevator is characterized in that, has damping arrangement, speed detection means and calculation portion, described damping arrangement be set at the cab chamber and cab frame that this cab chamber is supported between, can change extinguishing coefficient;

  • Described speed detection means detects the moving velocity of this elevator cage;

    The moving velocity that described calculation portion will be detected by above-mentioned speed detection means is as input, calculating is at the control signal of above-mentioned damping arrangement, the line output of going forward side by side, if moving velocity surpasses specified value, then above-mentioned calculation portion controls above-mentioned damping arrangement, and the extinguishing coefficient that makes above-mentioned damping arrangement is bigger during smaller or equal to the situation of specified value than moving velocity.
