Abstract:
1. A system for determining the speed at which an overspeed device is activated, the overspeed device having at least a brake pinion and a centrifugal weight, the system comprising: a testing apparatus comprising: a test pinion configured to engage with the brake pinion; a test shaft coupled to the test pinion such that the test pinion rotates when the test shaft is rotated; a motor coupled to the test shaft to rotate the test shaft; a motor controller coupled to the motor, wherein said motor controller controls the operation and speed of the motor; and a mounting bracket configured to hold the overspeed device for the test pinion to engage the brake pinion; and a recording apparatus comprising: a detector configured to detect when the centrifugal weight has been displaced and to determine the speed of the motor at the time the centrifugal weight is displaced.
