About the Tower Crane Interest Group (TCIG)

The Tower Crane Interest Group (TCIG) is a well-established group, formed in April 2003. The group is made up of tower crane owners, tower crane manufacturers, major contractors, training organisations and representatives from HSE.


The TCIG have published a number of Good Practice Guide documents including the Safe Use of Top Slew Tower Crane; Maintenance, Inspection and Thorough Examination of Tower Cranes; Safe Use of Self Erecting Tower Cranes; and the Climbing of Tower Cranes. In addition there is also a Tower Crane Climbing Safety DVD which can be obtained from the CPA, free of charge.


The group have currently published 46 Technical Information Notes (TIN’s) which can be downloaded free-of-charge from the TCIG publications page. The majority the TIN’s and all the Best Practice Guides have been badged by the HSE with their logo.


A major issue for both tower crane suppliers and users was the introduction of the European Harmonised Standard for tower cranes – EN 14439:2006. The standard specifies that tower cranes should be designed to take account of the out-of-service wind speeds laid down in the FEM standards 1.005. The HSE have advised that all tower cranes, regardless of age, must use the out of service wind speeds and calculation requirements laid down in the FEM 1.005, when providing out of service wind loadings for the base design.


CIRIA (The Construction Industry Research and Information Association) have updated their guidance document C654 on “Tower Crane Stability" with members of the TCIG being part of the team revising the document. Members of the TCIG and HSE staff further worked with the management of Network Rail (High Speed) to produce a new document covering requirements for tower cranes that are working within the collapse area of Network Rail property and was published in June 2014. The document can be downloaded free-of-charge from the TCIG publications page.
