All personnel working at heights must wear safety harnesses and be hooked to certified anchor points. 6. Emergency Procedures A rescue plan for workers at height must be in place.
Before commencing work, all equipment must be inspected, color-coded, and certified fit for use. Primary Lifting Equipment
A mobile crane with adequate lifting capacity and radius must be selected based on the heaviest component to be removed (usually the counter-jib or mast section).
For large tower cranes, an entire sequence of controlled lifts is executed to dismantle the crane piece by piece: climbing frame, cab assembly, and tower sections. tower crane dismantling method statement

A is a legally required safety document that outlines the exact steps, equipment, and responsibilities needed to execute this task without incident. This comprehensive guide serves as an industry-standard blueprint for engineering teams and safety officers to develop a site-specific tower crane dismantling method statement. 1. Project Overview & Scope of Work
Note: This sequence assumes the use of an external mobile crane for dismantling. If the crane uses a climbing cage to lower itself first, the self-climbing steps must precede this sequence. All personnel working at heights must wear safety
All small hand tools, pins, and wrenches must be secured via lanyards to the rigger's tool belt. No loose items are permitted on the crane structure during disassembly. Emergency Response Plan
Lift the assembly clear of the mast, control its orientation with tag lines, and lower it directly onto a flatbed transport trailer. Step 5.5: Mast Section Disassembly
Using the auxiliary mobile crane.
[Insert Specification, e.g., 300-Ton All-Terrain Mobile Crane] with sufficient boom length and radius capacity to reach the tower crane's highest components.
