The vehicle frame 100 is a bottom frame of a forklift truck in the prior art, which is composed of two bottom plates and an intermediate body connected between the two bottom plates. The two sets of dynamic balance structures 200 are arranged in a width direction on the vehicle frame 100, and are used to form a load bearing surface for carrying the cylindrical material, so as to be suitable for the material with a certain axial length. The two sets of clamping structures 300 are arranged at two ends of the dynamic balance structure 200, and are used to fix the cylindrical material on the dynamic balance structure 200.
