    INCIDENT: COLLAPSED TOWER CRANES

    Cranes brought down in storm winds were the same model

    It has been reported (30th Oct 2013) by Construction News that the two cranes which collaspse during high winds in London on Monday 28th October were same model of crane on different projects.

    Both cranes are reported to be Jost 158 luffing cranes.  CN states one crane (owned by City Lifting) collapsed on the Cabinet Office in Westminster. The second crane (owned by Delta Tower Cranes) came down on a  site on the Old Kent Road.

    City Lifting managing director Trevor Jepson told Construction News

    “We believe the two incidents most likely happened due to a locked slewing brake which prevented both cranes from slewing in the wind. Everything was done as per the crane manual.

    We only had one of that model of crane, but we have five other Jost cranes. We will be looking at whether we need to increase the out-of-service radius of those cranes beyond the guidelines.”

    Jost spokesman said:

    “Looking at the nature of similar damages, we believe the two incidents most likely happened due to a locked slewing brake, which prevented both cranes from slewing in the wind. 

    The out-of-service radius is completely correct and has been okay for all the 110-plus units of this kind of Jost cranes in the UK [in] past years. This is all we can say at the moment since the investigations are ongoing.”

    No injuries were reported on either site and damage is understood to be minimal.
