Hi, 

Ive been involved with an incident in which a lifting truck over turned, the truck is a compact type that lifts a cage of items up to a mezzanine floor for storage or down for despatch. . it has been determined that it was not a mechanical failing , and was infact incorrect positioning of a containment cage containing items, that took the tuck out of its safety stability triangle .

Riddor states that Collaspse , overturning of failure of load dearing part should be reported , they then go on to say failure in the context referes to componants that suffer mechanical breakdown during normal operation .

As no mechanical failure has occured - is this reportable under RIDDOR ?

I know the standard answer is "report to be covered" , but im just wondering if this is to the letter a "reportable" incident as the investigation has shown the truck to be mechanically sound. 

appreciate any thoughts - thanks
