摘要： A fall protection device includes a frame, a rotatable member, a safety belt, a braking plate, and at least one braking part, wherein a side surface of the frame has at least one stopper protruding therefrom. A stopper integrally protrudes from two adjacent side walls of a hole as a monolithic unit and extends in an arc shape. The rotatable member is rotatably and pivotally disposed on the frame. The safety belt winds around the rotatable member. The braking plate is coaxially connected to the rotatable member, whereby the braking plate rotates coaxially along with the rotatable member. The braking part is pivotally connected to an inner surface of the braking plate. When the braking plate rotates, the braking part is driven to pivot from a restoring position to a locking position to abut against the stopper, thereby to restrict the rotatable member from rotating.

摘要： A fall arrester includes holder, rotating drum, and braking module. The rotating drum is pivotally installed on the holder, and includes main body and pawl which has first abutting portion and is pivotally provided on setting part. The braking module is fixed to holder, and includes cover, friction plate, and ratchet plate, being coaxially set in order. The ratchet plate has second abutting portion on its periphery. When rotating drum rotates at speed greater than or equal to predetermined rotating speed, and first abutting portion moves to second position to abut against second abutting portion, the cover and ratchet plate rotate relative to friction plate, driven by rotating drum. Additionally, the cover and ratchet plate generate frictional resistance with friction plate respectively to stop the rotating drum. Thus, the braking module of the fall arrester can be replaced thereby enabling provision of a new braking module as an initial condition.

摘要： A fall arrester includes a holder, rotating drum, braking device, and dust cover. The rotating drum is pivotally provided on and within the holder, and includes a main body and at least one pawl; the main body has an accommodating part to be wound by a cable and a setting part. The pawl is pivotally provided on the setting part, and the braking device is fixed to the holder and between the holder and the setting part. When the rotating drum rotates quickly by pull of the cable, the pawl would pivot and make a part thereof abut against a part of the braking device to stop the rotating drum. The dust cover is fixed to the setting part, and thereby prevents dust from affecting the pawl and the braking device located therein, and thus to enhance safe use thereof.

摘要： A fall arrest device includes a braking device, a frame, and a rotating member connected to the frame. The rotating member includes a main body and a plurality of pawls which are pivotally connected to a mounting portion of the main body. Each of the pawls has an abutting portion, a pivot, and a body portion. The braking device has a plurality of abutted portions. When a rotation speed of the rotating member is greater than or equal to a predetermined rotation speed, the abutting portions abut against the abutted portions to stop a rotation of the rotating member. When the rotation speed of the rotating member is smaller than the predetermined rotation speed, the body portion of each of the pawls touches a periphery of the abutted portions and swings as an outer diameter of the abutted portions of the braking device changes.

摘要： A rope based fall protection device including a rotation unit, a brake unit, and a rope. A first end of the rope is connected to the rotation unit. The rope includes a first rope loop and a second rope loop that are wound around the rotation unit. A first retaining portion of a retaining ring is sleeved on the first rope loop and a second retaining portion thereof is sleeved on the second rope loop, such that the rope forms a rope section which has a fixed length between the second retaining portion and the first end and is wound around the rotation unit. When a free end of the rope is pulled by an external force to release the rope wound around the rotation unit in a direction away from the rotation unit, the retaining ring is broken to release the rope section of the rope. The external force is greater than or equal to a pulling force generated by a user's free fall. By releasing the rope section of the rope, the rotation unit rotates and simultaneously drives the brake unit to rotate to slow down or stop the rotation of the rotation unit.

摘要： A fall protection device includes a frame, a rotatable member being pivotally connected to the frame, a safety belt winding around the rotatable member, a braking plate, and a plurality of braking parts. A side surface of the frame has a connecting hole located on a center of the frame and a plurality of stoppers. The braking plate has a driven shaft passing through the connecting hole to be coaxially connected to the rotatable member. A number of the braking parts is the same as a number of the stoppers. The braking parts are pivotally connected to an inner surface of a plate body of the braking plate. When the braking parts are located at a locking position, an abutting portion of each of the braking parts is located at a position corresponding to one of the stoppers and abuts against one of the stoppers at the same time.
