Lower the counter-jib assembly safely to the designated ground zone. Step 5.8: Tower Head and Cabin Removal

Rig the mobile crane lines to the main jib using a balanced two-point or four-point hitch at the manufacturer's specified center-of-gravity points.

The method statement must also include quality assurance steps. Before, during, and after the dismantle, a checklist should be used to inspect all rigging gear (slings, shackles, etc.) for wear or damage. After the crane is fully disassembled, the site should be cleared of all debris and oil, and a final safety inspection conducted to ensure the area is safe for subsequent construction work.

Disconnect the remaining counterweight blocks (if applicable) and lower them. Unfasten the counter-jib tie rods from the tower head. Remove the main pivot pins at the counter-jib root.

This feature is based on common industry best practices (BS 7121, ASME B30.3, and ISO 12480). Always refer to the manufacturer’s specific manual and local regulations before performing crane dismantling.

Most tower cranes grow via an internal climbing cage (a hydraulic frame that slides up the mast). Dismantling reverses this process.

Rig and remove the remaining counterweight blocks from the counter-jib structure following the same safety protocols as Step 5.4. Step 5.7: Counter-Jib Dismantling

Operations must be postponed in cases of heavy rain, lightning, dense fog, or poor visibility. Working at Height

The dismantling of a tower crane at the completion of a construction project is one of the most critical and high-risk operations on a job site. Because tower cranes are massive, heavy, and typically situated in densely populated or heavily trafficked construction areas, taking one down requires precision, extensive preparation, and strict adherence to a .
