A multi-pulley telescopic mechanism, comprising a telescopic mechanism (24), a first extension boom pulling rope (19), a second extension boom pulling rope (18), a third extension boom pulling rope (17), a basic boom (1), a second boom section (2), a third boom section (3), a fourth boom section (6) and a fifth boom section (10), the second boom section (2), the third boom section (3), the fourth boom section (6) and the fifth boom section (10) being sequentially sleeved in the basic boom. Also disclosed is a crane, the crane comprising said multi-pulley telescopic mechanism. By providing the multi-pulley telescopic mechanism and the crane, the technical problems of high cost, low telescopic efficiency, and severe limitation on lifting capacity of five-boom section cranes in the prior art are solved.
