Emergency engineering (such as post-disaster reconstruction, flood control and disaster relief, emergency road construction) has the characteristics of tight time, heavy task and complex on-site conditions. Mobile crushing stations, with their flexibility, mobility and rapid deployment capacity, have become important equipment for emergency engineering, which can realize on-site crushing and resource recycling of materials.
### Application Advantages in Emergency Engineering
1. Rapid Deployment: Modular design, compact structure, can be quickly transported by trailer and installed on site, and the on-site installation time is less than 8 hours, which can quickly start production and meet the urgent needs of emergency engineering.
2. Flexible Mobility: Crawler-type or wheel-type mobile crushing stations can move freely on complex terrain, such as disaster-stricken areas with damaged roads and muddy slopes, and can reach the working site that fixed crushing equipment cannot reach.
3. Multi-Functional Application: It can process various materials such as construction waste, stone and soil, and produce different specifications of aggregate, which can be used for road base filling, building foundation construction and other emergency projects.
4. Independent Operation: Equipped with diesel-electric dual power supply, it can operate normally without relying on on-site power supply, which is suitable for emergency engineering with insufficient power supply.

### Application Case
In the post-flood reconstruction project in Bangladesh, a crawler mobile crushing station is used for on-site crushing of flood-damaged buildings and stones. The mobile station has a processing capacity of 120TPH, processing construction waste and stones into recycled aggregate, which is reused for emergency road construction and temporary housing foundation filling. The mobile station operates stably, ensuring the progress of the post-disaster reconstruction project, and has been highly recognized by the local government.
