A crawler crane lost stability on a job site in Durham, UK, last week, and began to overturn. Thankfully the boom landed on part of the building structure close before the crane had tipped beyond the point of no return.
The boom was damaged close to the butt section and we understand from reports that we have received that the near side track also sustained some damage. But most important of all no one was hurt. The crane, a Liebherr LR1100 is reported to be from the Select Plant fleet, and was working on a Sir Robert McAlpine office construction site on an industrial estate.
From information received the cause appears to be a result of overloading, but naturally there is no way that we can be certain of that. This unit is likely to have a recorder installed on the overload system, so an investigation should quickly reveal what actually caused the incident.
Hopefully any lessons learnt from this near miss will be shared widely within the industry, in order to prevent a similar thing happening elsewhere – next time we may not be as fortunate.
