The possibility that a fraction of the dark matter is comprised of massivecompact halo objects (MACHOs) remains unclear, especially in the 20-100$M_{\odot}$ window. MACHOs could make up binaries, whose mergers may bedetected by LIGO as gravitational wave events. On the other hand, thecosmological origin of fast radio burst (FRBs) has been confirmed. Weinvestigate the possibility of detecting fast radio bursts (FRBs) gravitationallensed by MACHO binaries to constrain their properties. Since lensing eventscould generate more than one images, lensing by binaries could causemultiple-peak FRBs. The angular separation between these images is roughly$10^{-3}$ mas, which is too small to be resolved. The typical time intervalbetween different images is roughly 1 millisecond (ms). The flux ratio betweendifferent images is roughly from 10 to $10^3$. With the expected detection rateof $10^4$ FRBs per year by the upcoming experiments, we could expect fivemulti-peak FRBs observed per year with time interval larger than 1 ms and fluxratio less than $10^3$ if the fraction of dark matter in MACHOs is $f\sim0.01$.A null search multiple-peak FRBs for time interval larger than 1 ms and fluxratio less than $10^3$ with $10^4$ FRBs would constrain the fraction $f$ ofdark matter in MACHOs to $f<0.001$.
