【渋谷再開発】渋谷のど真ん中で超巨大クレーンを組み立てる！渋谷スクランブルスクエア建設現場の超巨大350tクレーンに巨大「ウェイト」を装着する【圧巻】4K 60FPS

This is the absolute frontline of construction for the next landmark towers (Central & West Buildings) of Shibuya Scramble Square. Located directly above Shibuya Station—a hub traversed by millions daily—and right alongside active train lines like the JR Yamanote and Saikyo Lines, this is one of Japan's most extremely tight and congested job sites. Within a strictly limited workspace and a schedule managed down to the second, top-tier Japanese craftsmen (heavy rigging specialists and crane operators) take on the breathtaking assembly of a massive crawler crane (SCX3500-3)! 【🎥 Main Highlight】 The critical installation of the "counterweights" (rear weights), an absolute essential for this giant crane to safely lift tens of tons of construction materials. Lifted by an auxiliary all-terrain crane, massive blocks of steel and concrete (counterweights) are seamlessly set onto the rear of the crawler crane as if being sucked into place. The unspoken teamwork and masterful precision of the crew—aligning pins to the millimeter using only hand signals and radio calls from high above—is an absolute must-see! Enjoy the tense atmosphere of the site and the world-class craftsmanship supporting Japan’s infrastructure. 【🏗️ The "Signalman (Eye-Man)" and Hidden Site Rules】 Quietly giving instructions somewhere on screen is the "Signalman" (Rigging Signal Person), the true director of heavy machinery operations. No matter how skilled an operator is, blind spots from the cabin are inevitable. Standing on the ground or elevated platforms, the Signalman serves as the operator’s "second eyes," guiding the crane to the millimeter using radios and distinct hand signals. This high-stakes, extremely challenging job site also follows strict, absolute rules to prevent accidents: ``` "Only One Person Gives Signals" Having multiple people give instructions leads to confusion and catastrophic accidents. Even with dozens of workers on site, only the designated Signalman holds the absolute authority to direct the crane. "Never Stand Under a Suspended Load" To prevent potential falling accidents, the area directly beneath a suspended load is a strict no-entry zone, no matter how securely it is rigged. "Safety Checks via 'Pointing and Calling' (Yoshi!)" Rather than relying solely on unspoken coordination, workers combine visual checks, physical pointing, and vocal confirmation ("Yoshi!" / "All clear!") to reduce human error to zero. ``` 💡 【Bonus Highlight】 Sliding Diagonally!? Rare "Crab Steering" (Latter Half of the Video) Don't miss the second half of the video! 19:20 – Watch a specialized all-terrain crane with four axles per side (8+ wheels total) slide sideways and diagonally across the cramped site (known as "crab steering" or crab walking). This unique maneuver by a multi-axle steering heavy machine is a rare treat, made possible only by Shibuya's ultra-congested site! #ShibuyaRedevelopment #ShibuyaScrambleSquare #MassiveCrane #HeavyMachinery #ConstructionSite #Craftsmanship #Uchimiya #CrawlerCrane #AllTerrainCrane #Rigging #Signalman
