Crane Dismantling Method Statement | Tower

Note: This sequence assumes the use of an external mobile crane for dismantling. If the crane uses a climbing cage to lower itself first, the self-climbing steps must precede this sequence.

Lift the section away. Repeat this process sequentially for all remaining mast sections.

Before dismantling the tower crane, the following activities will be carried out:

To safely decommission and remove the tower crane using a mobile assist crane. 2. Personnel & Responsibilities

All method statements must incorporate stringent safety protocols, as the dismantling phase accounts for the majority of tower crane accidents. tower crane dismantling method statement

The dismantling of a tower crane is a complex process that requires careful planning and execution. This method statement outlines the steps and procedures for safely dismantling a tower crane. By following this method statement, the risk of accidents and injuries can be minimized, and the dismantling process can be completed efficiently and effectively.

Attach multi-leg wire rope slings or heavy-duty synthetic slings from the assist crane to the specific balance lifting points designated on the main jib.

Disconnect the jib tie rods/pendant bars from the tower top/A-frame.

Check the 48-hour localized weather forecast. Dismantling operations must cease if wind speeds exceed 10 m/s (approx. 22 mph) or if there is a threat of lightning or poor visibility. Note: This sequence assumes the use of an

With the jib removed, the remaining counterweights and the counter-jib assembly can be dismantled. This section typically contains the hoist machinery and electrical equipment.

: Conduct post-dismantling reviews to capture lessons learned and improve future procedures. Repeat this process sequentially for all remaining mast

For cranes anchored into the building floor slabs, the structural engineer must provide a patching and reinforcement repair method statement to fill the voids safely.
