To provide an elevator that can check the soundness of the standby brake without activating the brake mechanism.SOLUTION: An elevator 10 with a standby brake 30 comprises a brake circuit 41 with a standby brake blocking contactor, a bypass circuit 42 having a standby brake holding contactor connected in parallel with the standby brake blocking contactor; a contact b for standby brake blocking contactor, and a contact b for standby brake holding contactor. A control unit includes brake command means for transmitting a command to the standby brake blocking contactor; bypass command means for transmitting a command to the standby brake holding contactor, and soundness determination means 24 for confirming consistency between the command of the brake command means and the contact b for standby brake blocking contactor and consistency between the command of the bypass command means and the contact b for standby brake holding contactor.SELECTED DRAWING: Figure 2
