The invention discloses an electric heavy truck and a frame assembly thereof, and belongs to the technical field of vehicle bearing systems. The frame assembly comprises two longitudinal beams arranged oppositely and a plurality of cross beams connected between the two longitudinal beams in a crossing mode. Wherein the longitudinal beams are integral beams, and the cross beams are arranged at intervals in the extending direction of the two longitudinal beams; the battery frame is connected with at least two cross beams arranged at intervals through connecting pieces, the battery frame is of a frame structure defined by a first rod body extending in the X direction, a second rod body extending in the Y direction and a third rod body extending in the Z direction, the X direction is the front-back direction of the frame, the Y direction is the left-right direction of the frame, and the Z direction is the up-down direction of the frame; the at least two second rod bodies of the battery frame are located under the cross beams connected with the second rod bodies; a closed ring beam structure is defined by the cross beams, the connecting pieces and the battery frame. The design requirements for rigidity and light weight can be met.
