Inside a High-Risk Tunnel Rehabilitation. Mega Construction & Heavy Machinery Free Documentary

Описание: Step inside the world of mega construction and precision industry: from a 20-meter ITER excavation and CAT 385CL mud loading, to installing a massive precast clamshell box culvert in Ontario. Watch Germany’s Autobahn A9 rebuilt in two 48-hour windows with milling trains and Vögele pavers, then see AAC block walls rise with thin-bed mortar and smart service chases. We also cover cold-applied alligator crack repair, Swiss tunnel rehabilitation, 3D stringless slipform curb work, giant precast pontoons and air-lifted propane tank roofs, shipyard repairs, compact mini cranes, crawler crane assembly, ultra-large container ships, rail ballast cleaning, heavy transport, machining, forging, and automated valve production. Packed with real workflows, tolerances, logistics, and the calm control behind extreme loads.
