The invention discloses a highway heavy truck pantograph. The highway heavy truck pantograph comprises a pantograph arm, the upper end of the pantograph arm is connected with a pantograph head insulator, the pantograph head insulator is connected with a sliding plate, the lower end of the pantograph arm is installed on a bottom box body, and a balance rod is connected between the pantograph head insulator and the bottom box body. The bow arm is of a single bow arm structure, and the balance rod is hidden in the bow arm. The pantograph lifting system comprises a pantograph lifting cylinder, a fixed pulley, a steel wire rope and a pantograph lifting spring. A double-bow-head insulating connecting piece between a positive electrode sliding plate and a negative electrode sliding plate is a flexible connecting piece. The highway heavy truck pantograph has the characteristics of the long service life, high safety, reliable strength and the like, solves the problem that the electric heavy truck stably receives the current and takes electricity from a road contact network to drive the truck, and ensures the safe, reliable and normal operation of the electric truck.
