Demolition of cranes, covering the technical aspects, hazards, and practical considerations involved in the process.
Providing practical insights for professionals involved in demolition engineering and construction site management, particularly those tasked with managing or overseeing the removal of large, fixed lifting structures.
Speakers: David Stevens and Maximillian Ferard
Webinar Overview
Led by Max and Dave, the session begins with an overview of the different types of cranes that may require demolition, such as gantry cranes, overhead cranes, tower cranes, and portal cranes.
Each type presents unique structural characteristics and challenges that influence planning and execution.
The team then discuss key factors to consider before beginning demolition work.
This includes understanding the structure the crane is built into or attached to, its condition, weight, method of construction, and access constraints.
Importance is placed on thorough planning, risk assessment, and understanding the original build process, especially for cranes integrated into buildings or positioned in restricted environments.
A significant portion of the session is dedicated to highlighting the primary hazards associated with crane demolition.
These include instability during dismantling, working at height, access limitations, structural collapse, and the potential for uncontrolled movement or failure of lifting equipment.
The need for specialist equipment and techniques is noted, particularly where cranes are located in live environments or constrained sites.
Crane Demolition Case Studies
The second half of the webinar features four case studies that illustrate a range of real-world scenarios.
- Greenock Container Crane Dismantling
- Devonport Crane Dismantling
- A & P Tyne – 40-tonne dock crane
- Willesden Gantry Crane Pull Down
The session ends by looking at the importance of experience, preparation, and a clear understanding of both the crane and its environment.
