A bidirectional braking speed limiter relates to the technical field of elevator braking and comprises a rope wheel driven by a steel wire rope to rotate, an ascending speed detection mechanism and a descending speed detection mechanism which are arranged on the rope wheel, and an ascending clamping mechanism and a descending clamping mechanism which are used for emergently braking the steel wire rope after overspeed. The ascending speed detection mechanism and the descending speed detection mechanism are the same in structure, and the ascending speed detection mechanism and the descending speed detection mechanism are of a central symmetry structure relative to the center shaft of the rope wheel. The lifting clamping mechanism and the descending clamping mechanism are the same in structure, and the lifting clamping mechanism and the descending clamping mechanism are of a central symmetry structure relative to the center shaft of the rope wheel. According to the solution, most of the adopted parts can adopt the original one-way speed governor parts, so that the manufacturing cost can be greatly reduced.
