Salvaging, and Restoring the World’s First Caterpillar 797F — 30 Years Lost on the Seafloor

Описание: For 30 years, it lay silent beneath the sea…
the world’s first Caterpillar 797F — a titan of mining — lost to corrosion and pressure.
Now, the impossible recovery begins.
In this cinematic Salvaging, and Restoring episode, we reimagine the deep-sea discovery of the earliest generation 797F haul truck built by Caterpillar Inc. — found buried under steel debris, marine growth, and decades of saltwater damage. What was once the most powerful mining truck on Earth had become an ocean-floor relic.
This documentary-style journey follows every phase of the operation: subsea inspection, structural integrity analysis of the massive frame, heavy-lift planning for ultra-weight recovery, corrosion removal, hydraulic system restoration concepts, engine block reconstruction, chassis reinforcement, and full industrial refinishing.
From rust-eaten suspension arms to restored mechanical giants capable of moving mountains, this project showcases extreme-scale engineering and the limits of heavy machinery restoration.
This isn’t just about rebuilding metal.
It’s about resurrecting industrial history.
