The invention discloses an elevator brake device with a trigger mechanism. The elevator brake device comprises a brake mechanism and the trigger mechanism. The brake mechanism comprises a caliper and a fixed part; the caliper can move up and down relative to the fixed part. When an elevator is under maintenance, the trigger mechanism extends out; when a car of the elevator or its counterweight descends or ascends to a maintenance allowed limit position or exceeds the same, the trigger mechanism triggers the brake mechanism to move, and the caliper of the brake mechanism engages in friction with the fixed part so that the car or the counterweight slows down to descend or ascend and stops; after moving, the brake mechanism brakes the car or the counterweight in the height range, and the trigger mechanism keeps the caliper of the brake mechanism and the fixed part thereof attached; when the elevator runs normally, the trigger mechanism is collected, and the elevator runs normally in the travel range. By limiting the area which the car or the counterweight can reach during maintenance, staff on the top of the car or in a bottom pit can be provided with sufficient safety space when the elevator is under maintenance.
