About the Crane Interest Group (CIG)

Crane Interest Group (CIG)


The Crane Interest Group has been in existence for over twenty five years. It is the largest of all the SIGs commanding respect both in the UK and in Europe, where it is represented on ESTA, the European Mobile Crane and Heavy Transport Association.


Members of CIG were heavily involved in the initial drafting of the British Standard 7121- Safe Use of Cranes, which was first published in 1989. They have also been involved in all of the revisions which have subsequently taken place. The British Standard BS 7121 introduced the concept of Contract Lifting, which was a major step forward in the UK lifting industry. CIG helped produce CPA Contract Lifting Services Conditions to be used both for Contract Lifts and machine moving operations. They also helped produce the Supplementary Conditions for crane hire to use in conjunction with the CPA Model Conditions for the Hiring of Plant.


In 2003, new STGO regulations were published which enabled mobile cranes to travel with higher axle loadings and at more realistic road speeds. CIG was heavily involved, with the Department for Transport, in the revision of this order.


CIG has also introduced a series of safety publications, giving guidance both to the crane rental companies and their customers. These include the CPA Best Practice Guide(BPG) for Crane Hire and Contract Lifting, the BPG for the Maintenance Inspection and Thorough Examination of Mobile Cranes, BPG for Work at Height with Mobile Cranes, the BPG for Self Escorting of vehicles,  and the Safe Use of Lorry Loaders. 


There are ongoing discussions revolving around the issue of a roadworthiness test for mobile cranes. In principle, the members are in favour of the removal of the current crane exemption and for the introduction of an annual roadworthiness test, as it is seen as a benefit for reducing road accidents involving cranes. However, members believe that a transition period is required, particularly for cranes over 50 tonnes, in order to provide time for appropriately sized testing facilities to be provided around the country.


In September (2016), the CPA wrote to the Department for Transport announcing that its members are ready to move ahead and introduce a voluntary programme to inspect and test mobile cranes which were on a bespoke chassis for road-worthiness.


CIG members have agreed to form committee to investigate the issues involved and are to seek involvement from the representatives from the Department. It is intended that this initially will be a scheme for CPA members, but should it be accepted as a scheme backed by the Department for Transport, then the scheme could ultimately be used by all mobile crane companies/owners


All of the CPA guidance is available free of charge and can be downloaded from this website.
