The slewing assembly is usually the heaviest single lift in the operation.
Maximum permissible wind speeds for dismantling must be verified against the manufacturer’s manual (typically or 72 km/h , though lower thresholds apply to specific components like the jib). tower crane dismantling method statement
Standard PPE: Hard hat with chin strap, hi-vis vest, steel-toe boots, and safety glasses.
Dismantling a tower crane requires a meticulous, top-down sequence—involving hook block removal, counterweight reduction, and jib disassembly—to maintain structural balance. Key safety requirements include comprehensive risk assessments, strict adherence to manufacturer manuals, and mandatory site exclusion zones. Read the full method statement at Scribd .

| Hazard | Control | |--------|---------| | | Full body harness, double lanyard, and static line at all above 2m. Guardrails on temporary platforms. | | Crane collapse | Never exceed mobile crane’s load chart. Use load indicators. Do not dismantle out of sequence. | | Crushing between sections | “No hands in pinch points” rule. Use taglines and push-pull sticks. | | Electrocution | Survey for power lines before starting. Maintain minimum approach distances (10 ft for 50kV, more for higher). | | Sudden wind gust | Anemometer with audible alarm at 20 mph. Pre-planned tie-down for partially dismantled jib. | | Dropped objects | Tool lanyards, toe-boards on work platforms, exclusion zone below. |
