Commercial vehicle loading/unloading engineering truck

The invention discloses a commercial vehicle loading/unloading engineering truck which comprises a chassis with wheels, wherein a hydraulic telescopic outrigger is arranged below the chassis; two parallel tippable telescopic ramps are arranged above the chassis; the rear ends of both the two telescopic ramps are rotatably connected with lower cab aprons which are located on longitudinal extension cords of the telescopic ramps; carriage lap plates are arranged at the front ends of both the two telescopic ramps. The commercial vehicle loading/unloading engineering truck has the following benefits: 1, the pavement of the loading/unloading ramps is automatically completed through a series of mechanical operations, so that the working efficiency can be improved, the labor cost and the labor intensity can be reduced; 2, the engineering truck is capable of finishing the loading/unloading work without other auxiliary construction installation equipment and can be flexibly used at different loading/unloading sites; 3, the two telescopic ramps are mutually independent, large in strength and light in weight, and the front ends of the two telescopic ramps are fixedly connected with a commercial vehicle carrier vehicle, so that the stability and the security of a loading/unloading vehicle channel are improved; 4, a laser positioning device is arranged, so that the readiness time before the operation can be greatly shortened and the working efficiency can be improved.
