The invention relates to an elevator speed limiting tester. The elevator speed limiting tester comprises a tachometer wheel, an encoder and a tachometer wheel mounting mechanism. The tachometer wheelcomprises a tachometer wheel disc and a rotary shaft fixedly connected with the tachometer wheel disc. The tachometer wheel disc makes contact with the outer edge of a rope wheel, the encoder is connected with the rotary shaft, and the tachometer wheel is mounted on the tachometer wheel mounting mechanism. The tachometer wheel disc is a magnetic tachometer wheel disc. Compared with the prior art,the elevator speed limiting tester has the beneficial effects that the structure is simple, use is convenient, measured data are accurate, the measuring efficiency is high, and disassembly is facilitated.
