Videos and pictures, with dates and times of inspection can be helpful over time.** - [FAQs](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#main-content) - [Plant Construction (Hydromechanical Equipment / Lock & Dam)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#plant-construction-hydromechanical-equipment-lock-dam) - [Buildings (Movable Bridges, Locks, Wedges)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#buildings-movable-bridges-locks-wedges) - [Automotive (Hexapod, 6-axis machines, Sheet Metal Press Machinery)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#automotive-hexapod-6-axis-machines-sheet-metal-press-machinery) - [Material Handling (Bulk Handling / Coal Conveyor, Diverters, Snow Plows)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#material-handling-bulk-handling-coal-conveyor-diverters-snow-plows) - [Energy (Power Plants, Renewable Energy Control)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#energy-power-plants-renewable-energy-control) - [Food (Processing Plant Conveyors, Steering Actuators)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#food-processing-plant-conveyors-steering-actuators) - [Iron & Steel (Cold Rolling Mills, Tube Mills, Shear Applications)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#iron-steel-cold-rolling-mills-tube-mills-shear-applications) - [Cranes & Lifters (Lifting, Storm Pins, Grabbers)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#cranes-lifters-lifting-storm-pins-grabbers) - [Transportation (Rail, Heavy Equipment)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#transportation-rail-heavy-equipment) - [Machinery (Industrial, Material Positioning)](https://info.racointernational.com/en-us/knowledge-base/faqs?hsLang=en-us#machinery-industrial-material-positioning) - [General](https://info.racointernational.com/en-us/knowledge-base/general?hsLang=en-us) - [Compact Engineering Charts](https://info.racointernational.com/en-us/knowledge-base/compact-engineering-charts?hsLang=en-us) - [MA Engineering Charts](https://info.racointernational.com/en-us/knowledge-base/ma-engineering-charts?hsLang=en-us) [![RACO International L.P.](https://info.racointernational.com/hs-fs/hubfs/RACO-2.png?width=240&height=240&name=RACO-2.png "RACO International L.P.")](http://racointernational.com) 3350 Industrial Blvd | Bethel Park | PA | 15102 [mailto:raco@racointernational.com](mailto:raco@racointernational.com) Copyright © 2025, RACO International L.P.
