The invention relates to a double-front-axle structure with a lifting axle for a heavy truck. The double-front-axle structure comprises a first front axle, a second front axle, a first front-axle steering pull rod assembly, steering-machine steering knuckle arms, first front-axle steel plate springs, second front-axle lifting air bags, air-bag springs, second front-axle lifting brackets, second front-axle lifting cables and second front-axle steel plate springs. According to the double-front-axle structure disclosed by the invention, through the structural design of the second front-axle lifting air bags, the second front-axle lifting brackets and the second front-axle lifting cables, and through the lifting of the second front-axle lifting air bags, second front-axle tires are separated from a road surface, and the abrasion of the tires is reduced. When the heavy truck turns, the first front axle and the second front axle simultaneously turn, so that the phenomenon that because a second front axle cannot turn, sliding abrasion is caused is avoided. Through the structural design of the first front-axle steel plate springs, the second front-axle steel plate springs and the air-bag springs, the dead weight of the vehicle is effectively reduced.
