Tower Crane Dismantling Method Statement -

At a critical height—usually when the tower crane’s remaining top is 15–20 meters above the roof—the method statement triggers a handover. The tower crane is now too short to lift its own mast sections without the jib striking the building.

Now the mobile crane takes command.

This phase is the highest risk: two cranes interact within metres of each other. The method statement mandates an exclusion zone and a single signalman with absolute authority. tower crane dismantling method statement

Critical: Never stand under the jib during pin removal. Use tag lines. This phase is the highest risk: two cranes

This method statement covers the safe dismantling of a [Insert Crane Model] tower crane from a [Insert Site Address] construction site. The objective is to reduce the crane to manageable components using a mobile assist crane (or climbing crane/jib crane method) with zero incidents.

Before any bolt is loosened or section lifted, a thorough pre-dismantling audit must be completed and documented.

For practical use, a tower crane dismantling method statement should include this table format on the first page:
