The disclosure relates to an elevator braking device and an elevator system. The elevator braking device is used for performing braking operations on an elevator driving device comprising a brake disc (20) and it has a first state and a second state, and comprises: a body (10), with its interior accommodating at least a part of the brake disc (20), and a support member (30) axially fixed relative to the brake disc (20); a guide member (15) connected to the support member (30), wherein the body (10) is movable relative to the brake disc (20) along the guide member (15); a first friction member (11) and a control portion which are arranged inside the body (10) and adjacent to a first side (21) of the brake disc, wherein a part of the control portion is connected to the body (10), and the first friction member (11) moves along the guide member (15) under control of the control portion to be in contact with the first side (21) to perform a braking operation in a first state, and to be out of contact with the first side (21) in a second state, respectively; and a second friction member (12) arranged inside the body (10) and adjacent to a second side (22) of the brake disc (20), wherein the second friction member (12) is connected to the body (10) and is in contact with the second side (22) to perform a braking operation in the first state, and is out of contact with the second side (22) when the body (10) is moved along the guide member (15) as the first friction member (11) is out of contact with the first side (21) in the second state.
