(57) Abstract :
A brake (42) is tested in an elevator system (10) including a car (12) and a counterweight (14) connected to the car (12) by a rope (16).
The car (12) is positioned at a reference position in the hoistway (HW) adjacent to a hoistway limit switch (23), and the brake (42) is
engaged to hold the car (12) at the reference position. The rotating member (46) is then driven to provide a testing force on the brake
(42) that simulates a load in the elevator car (12) of at least a maximum rated load for the car (12). The brake test is terminated if the
hoistway limit switch (23) is actuated.
