Hemmat Engineering specializes in designing material handling systems, facilities and machines from concept development to installation and commissioning. We have extensive above ground and underground experience in electrical power systems, conveyors and human machine interface. In one project, we designed a complete electrical power and control system for a new coal stack tube storage, reclaim system consisting of primary power system study and voltage profiling, secondary substation design, motor control and lighting. The project used Allen Bradley PLC 5/40 with a hot backup processor and Controlview Operator's Interface.
In another project, we designed a fully automated material handling, tripper and crushing operation for a centrally controlled storage facility. The project involved a complete replacement of the existing control system with a PLC and computer based process monitoring and graphics system. The Square D Symax and Computer Technology ScreenWare packages were used on this project.
