Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic equipment, in particular to a mobile diesel-powered dual-circuit hydraulic power station. Background Art

[0002] After natural disasters such as earthquakes, floods and typhoons occur, the government will quickly launch rescue operations to save lives and protect citizens' property. During the rescue process, rescuers will frequently use hydraulic tools. The equipment that provides power for rescue tools is the hydraulic power station. The mobile hydraulic power station can be easily transferred to the required usage scenario.

[0003] The commonly used portable power stations on the market currently use internal combustion engines as power sources.

In view of the above-mentioned defects, the creators of the utility model have obtained the utility model after a long period of research and practice. Utility Model Content
