Problems solved by technology

[0002] Most of the rescue devices are used in the fields of industry and fire protection. They are mainly used for high-pressure quick disassembly of some waste products. With the one-piece design, the cutter head of the rescue device cannot be replaced, which has great limitations in practical applications; most of the current market adopts hydraulic rescue devices, which have strong demolition capabilities, but the characteristics of the hydraulic structure are It is large in size and mass, and it is extremely laborious in the process of use. When working in a small area, it is subject to certain limitations.
