Specifically, in the embodiment, the height difference between the bottom of the front cylinder 21 and the bottom of the rear cylinder 23 is 200mm, and compared with the height difference in the related art, the height difference between the front cylinder 21 and the rear cylinder 23 in the tank 2 is greatly increased, specifically increased by 100 mm.
The saddle is mounted below the front barrel 21 for cooperation with a tractor. The saddle is installed below the tank 2 in this embodiment, so that the height from the ground is reduced, specifically to 1180mm, compared to the height from the ground in the related art. Therefore, the stability of the whole transportation tank car is improved, and the anti-side-tipping capability of the transportation tank car is improved.
