Tower Crane Dismantling Method Statement ((install)) May 2026
Tower Crane Dismantling Method Statement: A Comprehensive Step-by-Step Guide
4.2 Crane Preparation
- Park the tower crane – jib positioned over the planned lowering area (usually clear of obstacles).
- Remove all loose items – slings, tools, rubbish from operator cab and jib walkway.
- Slew ring lock – Engage mechanical lock to prevent unwanted slewing during manual disconnection.
- Wind check – Use handheld anemometer. If wind > 25 mph (11 m/s) at height → Stop work.
8. Post-Dismantling Close Out
- Inspect all components for damage before transport.
- Update site drawings (crane removed).
- Debrief team: what went well, what to improve.
- Dispose of oils/greases per environmental regulations.

4. Equipment and Tools Required
The method statement must list all equipment to be used, including certification details. tower crane dismantling method statement
- Mobile crane (capacity typically 50–200 tons, depending on tower crane size) – for final jib and mast removal.
- Suitable rigging gear (spreader bars, shackles, slings of correct SWL – Safe Working Load).
- Hand tools (torque wrenches, sledgehammers, pin punches, hydraulic jacks).
- Climbing frame or auxiliary crane (in some internal climbing dismantles).
- Personal Protective Equipment (PPE): Full body harness with double lanyard, hard hat, steel-toe boots, high-vis vest, gloves, and eye protection.
- Communication system: Two-way radios with backup batteries.
Step 1: Remove Wind Vane & Electrical Disconnect
- Turn off main power at distribution box.
- Lock out / tag out (LOTO) the isolator.
- Remove the wind vane (anemometer assembly) and stow safely.

9. Lifting plan and sequence summary (typical)
Assumption: dismantling a luffing or hammerhead tower crane using a mobile crane with fly/jib removal. Follow manufacturer’s sequence if different.
- Pre-check: inspect crane condition, bolts, ladder access; tag out as required. Fit required lifting points and temporary braces.
- Lower jib to horizontal and secure; fit spreader beam to main hook if removing jib as single lift.
- Remove hoist/auxiliary equipment (counterweights, hoist drum, trolley) and lower to ground.
- Detach jib sections / counter-jib in controlled lifts using mobile crane(s); use taglines.
- Remove tower top section and top tie-ins (if tied to a building, disconnect per engineer).
- Sequentially dismantle tower mast sections from top down: rig mast section to mobile crane using spreader beam; lower to ground; ensure controlled rotation and stability.
- Remove cabin and slewing unit if required.
- Dismantle base section and remove foundation bolts or concrete plinth as specified.
- Load components onto transport vehicles; secure as per transport regulations.
- Conduct final site inspection; reinstate area.
Note: Provide a detailed engineered lift plan with load calculations for each lift, crane charts and rigging arrangement for every critical lift — attach as appendices.
