Hi there
looking for some clarification please ? Regards RIDDOR and lifting equiptment is it reportable if a counterweight on a concrete placing boom (not a crane) is struck by a load being lifted by a tower crane causing a counterweight on the placing boom to fall?
the crane, and no load bearing part of the crane, has failed, also the counterweight on the placing boom hasnt failed but has been subject to unexpected damaged which it has not been designed to withstand causing it to fall?
I am unsure where this would stand as it is down to user (crane operator / slinger / banksman) error rather than any failure of lifting equiptment.
many thanks in advance

Shedule 2, part 1 (section 1) of RIDDOR 2013 states that reportable occurrences regarding lifting equipment are ”The collapse, overturning or failure of any load-bearing part of any lifting equipment, other than an accessory for lifting.".
As the crane itself has failed and not a lifting accessory, i would suggest that a RIDDOR is carried out.
Hope this helps
Please see

Hi Thanks , the crane hasnt failed, it was an impact caused by a slinger that collided a load being moved into a counterbalance fixed to a boom rig which itself has counterweights one of which was hit and came off ? would this still be applicable ? the failure was on the part of the operator not the plant although the weight did come off (not the crane)
the rig assembley was not designed to be struck so would this be classed as failure of lifting equiptment?

Exactly,.
Because of the striking incident that led to the failure, (in my opinion) this would be classed as a failure of the lifting equipment.
I would suggest Reporting under RIDDOR.

I would have classed the counter weight as an accessory as it is interchangeable, so not strictly part of the crane. Also, it did not overturn and no load bearing part failed. So I don’t think I would report this, given the information above.

You seem pretty determined to pin the blame on the operator - did they set up the lifting equipment, plan site layout, devise the lifting plan(s)? In the HSE guidance on RIDDOR the line that gets attention is: "Incidents involving cranes must be reported irrespective of the nature of the work being done, and reports must not be restricted to those involving lifting and lowering." Yes there is probability no failure of any load bearing part of the tower crane or the boom rig that was struck occurred but the intention of RIDDOR is to collect information about infrequent events with a high potential to cause death or serious injury - a falling counterweight on a construction site to my mind would fit such curcumstances.
