The Riggers’ Forum is aimed at working riggers who rarely have an opportunity to discuss their opinions outside the workplace. In keeping with the tried and tested programme, a short topical presentation will be followed by an open forum for riggers to discuss the issues of the day. It’s free to attend and a great opportunity for the rigging community to meet and network. This year, the forum will begin with a presentation on the following topic:
Despite advances in technology, updated codes of practice and establishing rigging qualifications there remains a weakness between your rigging and the load you’re lifting - and it's often your truss. It can be a mechanical weakness and, if the engineering in this session is understood, it will help you to become more confident in the use of trusses to lift and support equipment. Topics include:
- If it’s OK to pick up from just the top chords
- When bracing patterns are important
- Understanding exactly what happens at mid-point pickups – ‘indeterminate suspension’.
