Tower Crane Dismantling Method Statement

The following sequence outlines the standard engineering workflow for a standard top-slewing tower crane. The exact sequence must mirror the manufacturer's reverse-erection manual.

Attach the lifting rigging to the crane cabin and apex/tower head. Disconnect and lower them. Rig the slewing ring and drive assembly.

: A well-developed method statement is the single most important safety document. Invest time in its preparation.

A is a critical, detailed document that outlines the safe and systematic procedure for taking down a tower crane after project completion. Dismantling is often considered more hazardous than erection due to the fatigue of the team, potential changes in site conditions, and the need to manage loose or worn components. tower crane dismantling method statement

Inspect all slings, chains, and shackles—the 3-3-3 rule suggests taking 3 seconds to inspect before every lift. Tower Crane Dismantling Procedure | PDF - Scribd

Note: Actual sequence depends on crane type (top-slewing, self-erecting, luffing jib). This example is for a typical crane.

[Insert Capacity, e.g., 250-Ton All-Terrain Mobile Crane] equipped with sufficient boom length and counterweights. Disconnect and lower them

Dismantling a tower crane is a high-risk operation that requires precision engineering, strict regulatory compliance, and a highly coordinated team. This method statement outlines the safe, systematic sequence for decommissioning and lowering a tower crane from a construction site.

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.

| Role | Responsibility | |------|----------------| | Assembly/Dismantling (A/D) Director | Supervises the entire operation, addresses all specified hazards, and ensures compliance with the method statement | | Crane Operator | Operates the crane during dismantling (as applicable) | | Riggers and Signalers | Handle load attachment and provide clear communication | | Ground Crew | Manage landing zones and component handling | | Safety Supervisor | Monitor compliance and intervene if unsafe conditions arise | Invest time in its preparation

A larger mobile crane (e.g., 150T or 160T) is often used to lower heavy sections like the jib and counter jib.

Finally, sling and lower the telescoping/climbing cage itself once the mast has been reduced to its minimal height. Step 5.11: Base Section / Fixings Removal

If a pin is seized or a bolt cannot be removed, do not apply excessive force using the assist crane. Use hydraulic splitters or penetrants while the load remains fully supported.

The general sequence for dismantling a tower crane using a mobile crane is essentially the reverse of its assembly. The following steps are typical in a method statement:
