Crab Nebula, as an active source of high energy gamma-rays, is a common standard source used for calibrating different gamma-ray telescopes and observatories. Since gamma rays with energies above 100 TeV from crab is reported, it is possible to detect gamma rays emitted from this nebula by a suitable ground based detector array. Alborz-I array is designed to study cosmic rays with energies around the knee of cosmic ray spectrum. In this paper, it is shown that the current location and configuration of Alborz-I, makes it impossible to detect Crab gamma rays. Our simulation shows that the average rate of gamma particle detection reaches to something above 1 gamma particle in 2 years, which is very difficult to distinguish from cosmic ray background. Finally some proposals to constructing an array with capability of detecting Crab gamma rays are presented.
