1. Rural infrastructure and field engineering: construction of village roads, water conservancy ditches, small bridges, and biogas digesters, especially suitable for areas without power grid coverage;
2. Remote self built houses/small construction sites: pouring and floor construction of brick and concrete houses in mountainous areas and towns, on-site mixing of small batches of concrete, without relying on commercial mixing;
3. Emergency engineering: Post disaster reconstruction, temporary road repair, rapid operation without power supply restrictions.
