The invention discloses a hoisting system for a novel large-tonnage bridging machine. The hoisting system includes guiding pulley assemblies, a hoisting crown block longitudinal beam, fixed pulley assemblies, a hosting trolley running mechanism, movable pulley assemblies, a hoisting assembly, a hoisting cart frame, a hoisting cart running mechanism, a left platform, a right platform, a left winch, a right winch and a longitudinal movement driving mechanism, wherein a single hoisting assembly and/or two hoisting assemblies are connected to the bottom of each two sets of movable pulley assembles. The hoisting system for the novel large-tonnage bridging machine is compact, concise and reliable in structure, and greatly reduced in whole weight; the new stringing mode also meets the requirement of the winch on winding a rope for two layers while meeting the deflection requirements of the rope, so that the service life of the steel wire rope is improved, and uniform stress of each hoisting rod on the hoisting assembly is ensured. Under the premise of usage technical requirement, the size of the support leg carrier roller box can be minimal, and the manufacture cost of the bridging machine is reduced.
