[0002] With the continuous expansion of industrial production, the demand for transporting large equipment such as large transformers and heavy machinery is increasing. Traditional transportation methods struggle to meet these requirements due to their bulk and weight. However, hydraulic self-propelled flatbed trucks offer sufficient carrying capacity and stability. For example, in underground production, coal and ore are often transported. Hydraulic self-propelled flatbed trucks are capable of carrying these heavy loads and delivering them stably to their destinations.

In continuous working scenarios, power supply or motor failure may affect work efficiency. In addition, the cost of components such as motors and batteries is relatively high, and a lot of costs are required for maintenance and replacement, resulting in low economic benefits.

[0004] Therefore, it is necessary to propose a hydraulic self-propelled flatbed truck to solve the above problems. Utility Model Content
