Abstract
The invention relates to lifting equipment, in particular, to designs of elevator speed limiting devices. The objective of the invention is simplifying the limiting device design, improving its reliability, reducing labor-intensity of its maintenance. The speed limiting device comprises vertical walls (2, 3) rigidly mounted on the base (1), a wheel hub (5) between them with a pulley (6) rigidly fixed on it. The pulley 6 is enveloped by a flexible member. The limiting device is equipped also with the pulley (6) braking mechanism, a mechanism for remote actuation of the speed limiting device and a safety switch (16) with a reset device. The mechanism for remote actuation of the speed limiting device includes a clamp (13) rigidly connected to a stabilizer (14) and to a bidirectional actuating unit (15). The stabilizer (14) is equipped with an elastic member (18). When the bidirectional actuating unit (15) is turned on, the clamp (13) is capable of interacting with a member (8) of the pulley (6) braking mechanism or with the safety switch (16), depending on the direction of actuation of the bidirectional actuating unit (15).
