This elevator brake performance evaluation apparatus comprises: a power supply control unit for controlling the power supply to brakes that stop an elevator car when the power supply is cut off; a travel amount detection unit for detecting the amount traveled by the car; a deceleration-start detection unit for detecting when the car has started to decelerate; and a braking delay distance computation unit for calculating the braking delay distance of the car on the basis of the travel amount detected by the travel amount detection unit from when the power supply control unit cuts off the powersupply to the brakes to when the deceleration-start detection unit detects that the car has started to decelerate. As a result, a brake adjustment point corresponding to the braking delay distance canbe ascertained.
本发明的电梯的制动器性能评价装置具备:电力供给控制部,其控制对制动器的电力供给,该制动器在电力供给被切断时对电梯的轿厢进行制动;移动量检测部,其检测轿厢的移动量;减速开始检测部,其检测轿厢开始减速的情况;以及空走距离运算部,其根据从电力供给控制部切断对制动器的电力供给时起至减速开始检测部检测出轿厢的减速开始时为止的、移动量检测部检测出的移动量来求出轿厢的空走距离,由此,能够掌握与空走距离对应的制动器的调整部位。
