The remaining counter-weight is left to balance the crane while the jib is shortened. Step 3: Shortening or Removing the Jib

The main jib is typically removed as a complete unit or in pre-determined sections if space is constrained.

High-tensile mast bolts must never be forced or cut. Pins must be removed using non-sparking brass drifts. Bolted joints must be loosened systematically following structural loading principles. tower crane dismantling method statement

Supervises the entire dismantling process. Mobile Crane Operator: Certified operator.

Harnesses, helmets, high-visibility clothing, and safety shoes. 5. Dismantling Sequence (Typical Top-Slewing Crane)
