188.8.131.52.4 Driving-Machine Brake(s)
For elevators installed under ASME A17.1-2000/CSA B44-00 and later editions, have the brake setting verified in accordance with the data on the brake marking plate.
Upon completion of the test, the means of adjusting the holding capacity shall be sealed to prevent changing the adjustment without breaking the seal. The seal shall bear or otherwise attach the identification of the person or firm that installed it. (See also 184.108.40.206.2, Periodic Test Record.)
(a) Test with load per Table 220.127.116.11.4. Place the load as shown in Table 18.104.22.168.4 in the car. The driving-machine brake, on its own, shall hold the car with this load. With no load in the car, the driving-machine brake shall hold the empty car at rest, and shall decelerate an empty car traveling in the up direction from governor tripping speed. The driving-machine brake on freight elevators of Class C2 loading, when loaded to their maximum design load, shall hold the elevator car at rest (Item 22.214.171.124).
(1) Any method of verifying conformity of the driving-machine brake with the applicable Code requirements (see 126.96.36.199 and Table 188.8.131.52.4) shall be permitted, including the testing method of the brakes with or without any load in the car, provided that when applied, the method verifies that the brake performs or is capable of performing in compliance with (a).
