Identification of the qualified personnel involved, such as the Appointed Person, the lift supervisor, and the specialized dismantling technicians. 2. Planning and Regulatory Compliance
Safety harnesses (with double lanyards), hard hats, hi-vis vests, and steel-toed boots. 5. Step-by-Step Dismantling Procedure Phase 1: Preparation
The assist crane supports the counter-jib while pins are removed. The tower head (apex) is disconnected and lowered. Phase 5: Mast Section Removal
Conduct a comprehensive safety hazard assessment of the affected work area to identify potential hazards and appropriate safety measures. The controlling entity must ensure that tower crane foundations and structural supports are in proper condition before dismantling begins. Assess site and ground bearing conditions to ensure they can support both the crane during disassembly and any auxiliary equipment. tower crane dismantling method statement
Certified wire rope slings, web slings, shackles, and spreader beams with valid third-party test certificates. 3.2 Tools & Personal Protective Equipment (PPE) Impact wrenches, torque wrenches, and pinning hammers. Taglines (minimum two 20-meter nylon ropes).
Take the tension on the mobile crane, remove the retaining pins, and lower the counterweight block to the ground.
Understanding the Tower Crane Dismantling Method Statement Dismantling a tower crane is a complex engineering operation that requires meticulous planning and coordination. Unlike the initial assembly, dismantling often takes place once a project is nearing completion, which means the crane may be surrounded by finished structures, active utilities, or public infrastructure. Identification of the qualified personnel involved, such as
No loose tools permitted at height. All hand tools must be tethered to the worker’s harness. Exclusion zones must be enforced below.
Responsible for the overall planning, risk assessment, and preparation of the method statement. They hold ultimate authority over the operation.
A physical barrier at ground level to prevent unauthorized entry into the "drop zone." Phase 5: Mast Section Removal Conduct a comprehensive
Attach the mobile crane rigging to the designated lifting lugs on the main jib. The rigging must match the center of gravity (CoG) specified in the manual.

Only the slewing power should remain active to facilitate rotation of the upper structure during dismantling, if required.

Workers must wear full-body harnesses with dual lanyards, hooked 100% of the time to certified anchor points or temporary lifelines.
