回収用制動機。 a pair of grooved rollers pivotally supported on the top of the board;
A rotating shaft rotatably supported at the bottom of the board, a lever fixed to one end of the rotating shaft, an arm fixed to the other end of the rotating shaft across the board, and the arm. a braking roller which is pivotally supported at its end so that its rotational resistance can be adjusted, and which is located below the grooved roller and is eccentric with respect to the grooved rollers and is disposed opposite to these so as to be able to clamp the electric wire; The brake roller and the grooved roller are rotated from a certain rotational angular position with a lever that is rotatably locked to the upper part of the substrate, the other end of which is rotatably locked to the middle part of the lever, and leaves the gap between the brake roller and the grooved roller in an open state. A tension spring that urges the brake roller to approach the grooved roller side by a spring force after passing the dead center within the rotation range of the lever that reaches another rotational angle position of the lever to be brought into the approach state, and the substrate and the electric wire. A brake for recovering a suspended object, which is equipped with a rope that connects the suspended object above.
