"Where demolition meets delicate extraction—watch a construction specialist perform surgical removal of a broken concrete column with custom rigging and calibrated force."This fascinating footage captures a worker manually raising a cylindrical core cutter, then extracting the severed concrete stump with specialized clamps. Witness the perfect balance of primitive leverage and modern material science.
The Extraction Process:
Manual Winching: Hand-cranking the 200kg cutter vertically
Core Clamping: Titanium jaws gripping the fractured edge
Controlled Extraction: 5° rocking motion to break suction
Why This Method Wins:
✔ Zero Structural vibration damage
✔ 100% Reusable cutter blades
✔ 1cm Precision in cut elevation
Operator's Secrets:
⚠ Apply vegetable oil to cutter threads
⚠ Hum at 120Hz to detect hollow spots
⚠ Always extract against the pour grain
Final Thought:
This isn't just debris removal—it's reverse engineering of construction itself, where every action respects the original forming process.
