Sling the cathead structure and unbolt it from the slewing assembly. Lower it to the ground.
The auxiliary crane's position and capacity must be calculated to safely lift each component at its maximum radius. Detailed rigging plans should be prepared for each major lift.
Responsible for the overall planning, risk assessment, and execution of the lifting operations. They have the absolute authority to halt operations due to safety concerns.
Take the weight of the empty counter-jib with the assist crane. tower crane dismantling method statement
Responsible for attaching loads and directing the assist crane.
Safe-working platform ladders must be used by erectors to access and remove the connection pins connecting the jib to the tower apex/cathead.
All lifting accessories (slings, shackles, chains) must possess valid thorough examination certificates (e.g., LOLER/OSHA logs) and color-coded tags.
(Approved by the Appointed Person/Lifting Engineer) 3. Roles and Responsibilities Are there any , such as nearby overhead
The assist crane hooks onto the jib at the manufacturer-specified lifting points. Riggers disconnect the jib pins at the tower head.
Swing the main jib slowly away from the tower crane structure using the assist crane, control it via taglines, lower it to the ground, and disassemble it into shipping sections. Step 3: Counter-Jib Removal
The climbing frame, which was used to raise the crane during its operational life, is removed. This component is typically dismantled in sections.
Systematically unbolt and remove tower sections (masts) one by one. If a was used, dismantle and lower it last. 6. Safety & Environmental Controls The auxiliary crane's position and capacity must be
Attach the lifting tackle to the top mast section or climbing frame (if applicable).
Appendix C: Personnel Certifications (CPCS/OSHA or local equivalent cards) Appendix D: Risk Assessment Matrix (RAMS)
Attach the assist crane slings to the designated lifting points on the main jib.
Collect and sort all discarded rags, grease containers, and damaged hardware for disposal in accordance with local environmental regulations. 9. Sign-off and Appendices
Monitor wind speeds continuously. Dismantling must stop if wind speeds exceed the manufacturer’s limit (typically 10–12 m/s) or if visibility is poor.
