Mechanical interface
Mounting points, reach, clearance, transport state and movement envelopes define whether equipment can be installed and operated without interference.
Hydraulic interface
Pressure, flow, oil specification, filtration, cooling, hose routing and simultaneous demand determine power-unit sizing and response.
Electrical and control interface
Supply, enclosure, hazardous-area requirements, I/O, communications, command ownership and safety functions determine how equipment coordinates.
Operational interface
People and procedures remain part of the system. The project must define who controls each step, where operators stand and how manual recovery is performed.
One interface matrix
Bringing these items into one review reduces late changes and creates a clearer basis for factory and site acceptance.
