Integration That Works
Grain systems require more than equipment—they require coordination across foundations, structures, electrical, controls, and material handling. Sentry self-performs the critical trades needed to deliver a complete, integrated system. Our Electrical division wires every component. Our Controls & Automation team builds UL-listed panels in-house.
Our Crane Service handles heavy lifts, and our FieldWorks division coordinates foundations and site work. The result is a single-source solution with no finger-pointing and faster commissioning.
Challenges We Solve
- Coordinating multiple trades and vendors for turnkey grain system installations
- Integrating new Brock equipment with existing grain handling infrastructure
- Meeting tight harvest-season deadlines with reliable scheduling and self-performed work
- Ensuring electrical and controls systems are properly designed for grain handling environments
- Finding qualified service and repair support for long-term system maintenance
