Abstract
A method of testing elevator car braking distance includes verifying that an elevator car is empty. The method also includes initiating a test procedure. The method further includes triggering a safety actuation device to actuate at least one safety brake to stop an elevator car. The method yet further includes recording braking data during a braking period. The method also includes recording braking data with at least one piece of elevator car equipment. The method further includes generating a braking data report that includes at least one of braking distance and braking deceleration of the elevator car.

A method of testing elevator car braking distance comprising:
- verifying that an elevator car is empty;
- initiating a test procedure;
- triggering a safety actuation device to actuate at least one safety brake to stop an elevator car;
- recording braking data during a braking period;
- recording braking data with at least one piece of elevator car equipment;
- and
- generating a braking data report that includes at least one of braking distance and braking deceleration of the elevator car.
A method of automated testing of elevator car braking distance comprising:
- initiating a test procedure with a device;
- triggering an electronic safety actuator to actuate at least one safety brake to stop an elevator car;
- recording braking data with at least one piece of elevator car equipment;
- and
- generating a braking data report that includes at least one of a braking distance and braking deceleration of the elevator car.
An elevator brake testing system comprising:
- an electronic safety actuator coupled to an elevator car for actuating a safety brake, the electronic safety actuator detecting braking data during a brake test;
- a controller in operative communication with the electronic safety actuator for transferring the braking data;
- a remote device;
- a camera operatively coupled to the elevator car, the camera positioned to capture an image of brake marks on a guide rail left by the safety brake;
- and
- a network wirelessly connecting the camera to the controller, and the controller to the remote device, the remote device remotely initiating an automated test of the elevator brake testing system by triggering the electronic safety actuator, the controller communicating an elevator car braking distance to the remote device.
