In some embodiments of the present invention, the working platform 120 is connected to the engineering truck body 110 through driving members at both sides of the Y direction. Optionally, the driving member is a hydraulic cylinder 150.
Therefore, the displacement detection sensor 130 and the controller 140 can detect the expansion and contraction amounts of the two hydraulic cylinders 150 in real time, and timely adjust the expansion and contraction amounts of the two hydraulic cylinders 150, so that risks of breakage and the like of the hydraulic cylinders 150 caused by inconsistent expansion and contraction amounts of the hydraulic cylinders 150 at two sides are avoided, and the operation safety of operators is improved.

Alternatively, the displacement detection sensor 130 may be a laser displacement sensor, a pull-wire displacement sensor, an inductive displacement sensor, or a magnetic grating ruler displacement sensor.
In some embodiments of the present invention, as shown in fig. 5, each displacement detection sensor 130 is provided in a corresponding hydraulic cylinder 150 to detect the displacement amount of the piston of the hydraulic cylinder 150. That is, the displacement detection sensor 130 is installed in a built-in manner, and the displacement detection sensor 130 can directly detect the displacement of the piston of the hydraulic cylinder 150, so that the displacement detection sensor 130 is not affected by the external environment, and the reliability is high, and the detected displacement is more accurate.

In some embodiments of the present invention, an electrically controlled proportional valve 160 is disposed between the controller 140 and each driving member, and the electrically controlled proportional valve 160 receives signals from the controller 140 to adjust the amount of telescoping of the driving member. Therefore, the two driving parts can be conveniently adjusted, and the two driving parts are ensured to have the same expansion and contraction amount.
