This utility model discloses a simple, electrically adjustable engineering vehicle, comprising: a U-shaped base, an electrical control box, electrically adjustable columns, and a testing machine connecting assembly. The lower end of the U-shaped base is equipped with several casters, and the electrical control box is located at the upper end of the U-shaped base. Two electrically adjustable columns are positioned on either side of the U-shaped base, with one column positioned close to the electrical control box. The testing machine connecting assembly is mounted on the two electrically adjustable columns. By applying this utility model, a simple, electrically adjustable engineering vehicle is proposed. The electrical control box controls the raising and lowering of the electrically adjustable columns, enabling electric adjustment of the testing machine's height. This improves operator comfort and operational accuracy, allowing operators of different heights to quickly adjust the testing machine height according to their needs. Furthermore, by embedding the casters within the U-shaped base, the distance between the U-shaped base and the ground is reduced, improving the overall passability of the engineering vehicle.
