Tower Crane Dismantling Method Statement

Introduction

The following method statement outlines the procedures for the safe dismantling of a tower crane. The crane in question is a [insert crane model, e.g., Liebherr 630 EC], with a height of [insert height, e.g., 80 meters] and a lifting capacity of [insert lifting capacity, e.g., 10 tons]. The crane is located at [insert location, e.g., a construction site in downtown city]. The dismantling work will be carried out by a team of experienced personnel from [insert company name, e.g., Crane Solutions Ltd.].

Scope of Work

The scope of work includes the complete dismantling of the tower crane, including the tower, slewing unit, jib, and counter jib. The work will be carried out in accordance with the manufacturer's instructions, relevant industry standards, and applicable regulations.

Pre-Dismantling Checks

Before commencing dismantling work, the following checks will be carried out: A Method Statement for Tower Crane Dismantling is

  1. Weather Conditions: The weather conditions will be checked to ensure that the dismantling work can be carried out safely. No work will be carried out in adverse weather conditions, such as high winds, thunderstorms, or heavy rain.
  2. Crane Condition: The crane will be inspected to ensure that it is in a safe condition for dismantling. This includes checking for any damage, wear, or corrosion on the crane's structural components, as well as ensuring that all electrical and hydraulic systems are functioning properly.
  3. Site Conditions: The site will be inspected to ensure that it is safe for dismantling work. This includes checking for any obstacles, overhead power lines, or other hazards that could interfere with the dismantling work.

Dismantling Sequence

The dismantling work will be carried out in the following sequence:

Step 1: Preparation (Duration: 1 day)

  1. The crane will be secured to prevent any movement during dismantling.
  2. The jib and counter jib will be lowered to the ground and secured.
  3. The slewing unit will be locked in place to prevent any rotation.

Step 2: Removal of Jib and Counter Jib (Duration: 2 days)

  1. The jib and counter jib will be disconnected from the slewing unit.
  2. The jib and counter jib will be lowered to the ground using a mobile crane or a hydraulic crane.
  3. The jib and counter jib will be removed from the site.

Step 3: Dismantling of Slewing Unit (Duration: 2 days)

  1. The slewing unit will be disconnected from the tower.
  2. The slewing unit will be lowered to the ground using a mobile crane or a hydraulic crane.
  3. The slewing unit will be removed from the site.

Step 4: Dismantling of Tower (Duration: 3 days)

  1. The tower will be divided into sections using a hydraulic cutter or a bandsaw.
  2. Each section will be lowered to the ground using a mobile crane or a hydraulic crane.
  3. The tower sections will be removed from the site.

Step 5: Removal of Foundation Equipment (Duration: 1 day)

  1. The foundation equipment, including the foundation bolts and anchorages, will be removed.
  2. The foundation will be made good to its original condition.

Safety Measures

The following safety measures will be implemented during the dismantling work: Weather Conditions : The weather conditions will be

  1. Personal Protective Equipment (PPE): All personnel involved in the dismantling work will wear the required PPE, including hard hats, safety glasses, gloves, and steel-toed boots.
  2. Fall Protection: Fall protection equipment, including harnesses and lanyards, will be used to prevent falls from heights.
  3. Load Control: Load control measures will be implemented to prevent loads from swinging or falling during lifting operations.
  4. Fire Safety: Fire safety equipment, including fire extinguishers, will be on site.

Environmental Considerations

The following environmental considerations will be taken into account during the dismantling work:

  1. Noise Control: Noise control measures will be implemented to minimize noise disturbance to nearby residents and wildlife.
  2. Dust Control: Dust control measures will be implemented to minimize dust generation during dismantling work.
  3. Waste Management: All waste generated during dismantling work will be disposed of in accordance with relevant regulations.

Quality Control

The following quality control measures will be implemented during the dismantling work:

  1. Inspection and Testing: All equipment and tools used during dismantling work will be inspected and tested regularly.
  2. Supervision: The dismantling work will be supervised by experienced personnel.
  3. Documentation: All dismantling work will be documented, including photographs and written records.

Emergency Procedures

The following emergency procedures will be in place during the dismantling work:

  1. First Aid: A first aid kit will be on site, and a first aid trained person will be available.
  2. Fire Emergency: A fire emergency plan will be in place, including evacuation procedures and fire extinguisher locations.
  3. Accident Reporting: All accidents will be reported and investigated in accordance with relevant regulations.

Conclusion

The tower crane dismantling work will be carried out in accordance with the manufacturer's instructions, relevant industry standards, and applicable regulations. The work will be carried out by a team of experienced personnel, and all necessary safety measures will be implemented to ensure a safe and successful dismantling operation.

Step 7: Base Removal

  • Excavate around foundation bolts (if concrete base).
  • Cut anchor bolts with oxy-acetylene torch – require hot work permit.
  • Remove base plate or foundation sections using mobile crane.

Phase 4: Remove the Slewing Unit and Turntable

  • Step 4.1: Disconnect all electrical and hydraulic lines to the slewing ring.
  • Step 4.2: Attach mobile crane to four-point lifting spreader on top of slewing unit.
  • Step 4.3: Remove mast-to-slewing bolts.
  • Step 4.4: Lift the slewing unit clear of the mast stack. Lower to ground.
