The right level of supervision must be in place for lifting operations, reflecting the degree of risk and personnel involved in the particular lifting operation. (k) measures to secure safety of persons not involved in the lifting. (j) load chart: boom angle, load radius and lifting capacity and (h) preventing unauthorised movement or use of the crane (g) maintenance and inspection of crane and its equipment (f) thorough examinations, reports and other documents (e) types of lifted load, including rigging technique and component (d) supervision of works by lifting supervisor having the necessary authority (c) provision of competent and sufficient number of workers (supervisor, operator, rigger and signalman) (b) selection, provision and use of a suitable crane and work equipment, including safe slinging and signalling arrangements (a) planning and HIRARC – including site preparation, crane erection and dismantling The method statement should be understood by everyone involved.
The plan should result in a written safe system of work or a method statement. The effects of thorough planning of lifting operations were seen to have positive effects on the efficiency, productivity and safety of the site” Sertyesilisik et al., 2010, An investigation of lifting operations on UK construction sites. “Thorough Planning: The planning of lifting operations is varied, and is conducted differently depending on the crane team’s experiences and knowledge. The plan should ensure that the lifting equipment stays safe for the range of lifting works for which the equipment might be used. So that any lifting work is carried out safely.
(b) the risks identified by a risk assessment
The person appointed to plan the lifting work should have adequate practical and theoretical knowledge and experience of the lifting work being undertaken. All lifting works should be planned, taking into account all foreseeable risks, so they are carried out safely.
