Fire-Breathing Drill : 1970s Gas-Powered Rock Crusher In Action !

Описание: A Little Wisdom Helps You Become Smarter !

This footage captures a worker operating a gasoline-driven Internal Combustion Rock Drill (Model 30A), drilling into solid rock. Once a common sight in mines and construction sites from the 1970s–1990s, this machine embodies an era when brute-force engineering conquered remote terrain.

How It Works: No Grid? No Problem.

The Model 30A’s core innovation was its self-contained design:

A 2-stroke gasoline engine directly powers the drill mechanism.

An integrated air leg (pneumatic support column) pushes the drill bit into rock with adjustable force.

Simultaneous air/water injection clears debris while drilling.
Crucially, it operated without electricity or compressors—ideal for roadless mountains or isolated mines.

Raw Power, Real Sacrifice:

This drill got the job done, but demanded toughness:

▶️ High Vibration: Sustained use caused severe hand-arm vibration syndrome (HAVS) in operators.

▶️ Exhaust Fumes: Gas engine emitted thick, toxic smoke in confined tunnels.

▶️ Heavy & Loud: At ~100 lbs (45 kg), it required strength. Noise exceeded 110 dB.

Why It Faded From Work Sites:

Modern hydraulic/electric drills replaced it for three key reasons:

Efficiency: New drills hit 2–3x faster with half the fuel.

Safety: Reduced vibration & zero fumes protect workers.

Precision: Automated feeds allow deeper, straighter holes.

Legacy: Though obsolete, the Model 30A was vital infrastructure in developing regions. Its roar echoing in quarries remains a powerful symbol of human grit reshaping nature—one explosive drill hole at a time.
