The full dataset (1989-2000) of the EAS-TOP scintillator array has been exploited to search for γ-ray emission from the Crab Nebula at primary energies exceeding the typical ones of Cerenkov light detectors. Different selection criteria have been applied to the data in order to select different primary energies, i.e., Etyp 1 = 20 TeV and Etyp 2 = 100 TeV. The total ON-source time is 12925 hours, and the number of ON-source events are N1 = 1.2 · 107 and N2 = 1.3 · 105 (in angular windows ˜ 1 ≈ 2 · 10-2 sr and ˜ 2 ≈ 3 · 10-3 sr, respectively). No D.C. emission has been detected: the 90% c.l. limits are Φ(> 20TeV) < 2.6 · 10-13 cm-2 s-1 , and Φ(> 100TeV) < 3.9 · 10-14 cm-2 s-1 . Using a power-law index of the Crab energy differential spectrum γ = 2.5 (as reported by Cerenkov light detectors), the obtained 90% c.l. differential flux limits are: dΦ dE < 1.9 · 10-14 cm-2 s-1 TeV-1 , at 20 TeV, and dΦ dE < 5.9 · 10-16 cm-2 s-1 TeV-1 , at 100 TeV.
