Claims

[Scope of utility model registration request]

In a safety device for lifting and lowering that is used in a fall prevention device based on a wire rope, the main body is provided with a connecting fitting and a contact plate on the upper side, and an arm portion from which a part of the main body extends downward, and the arm portion. A movable part is provided which cooperates with the wire rope to engage and disengage the wire rope.
Although the rotation is restricted by the stopper, it is loosely fitted into the main body, and cam parts are provided at both ends, and when the rotation is made, it collides with the contact plate and presses the contact plate towards the wire rope side. As it is supposed to be displaced,
The movable part is hinged to the main body so as to be openable and closable, and the free end side is fixed to the distal end of the arm part by a locking means so as to join the hands of the arm part, and the movable part is attached to the inner side of the arm part. 1. A safety device for lifting and lowering, characterized in that a semicircular recess is provided in the recess, and a wire rope is slidably inserted into the recess.
