Challenge
- The equipment is installed outdoors, adjacent to a building wall, and operates up to the rooftop level.
- The site is located in a chemical industrial park, requiring strict explosion-proof and safety compliance.
- No pit excavation was allowed, increasing the complexity of structural and access design.
- Large and heavy materials needed to be transported vertically across two levels, with stable and precise positioning.
- The client required a fully enclosed structure to prevent dust, weather exposure, and safety risks.
