Tower cranes are a vital element in the construction process. There are around 1500 cranes in the UK and at any time around 1000 are in use. Tower cranes are often in use on construction sites in urban areas and, although rare in the UK, any collapse of the crane is likely to result in injury to members of the public outside the boundaries of the site as well as personnel working inside the site. Collapse of tower cranes also presents a risk to adjacent railways and roads. This guidance aims to bring together important practical and design issues that impact on health and safety and to present a current understanding of best practice based on the experience of a wide cross-section of the industry. The document is intended to promote the safe design of foundations for, and use of, tower cranes through an improved understanding of temporary works design and health and safety issues.
