    Don't think this was the case.

    There were 8 attachment points to the slab, and they were all fixed to the spreader without any sheaves or chance to
    equalize the load on them as the slab tilted up.

    This is why one of the uppermost attachment points failed, it was taking all the load once the slab was near to 90 degrees.
    This was a rigging error I believe. Two of those cables, shackles, and re-bar links could not be expected to hold the entire
    thing up, when vertical.

    The upper bridles ride on a set of sheaves as do the lowers. The pick points are installed so that the wall will naturally tilt vertical as it's lifted. The cable itself failed at the uppermost right side attach area according to the info released so far.

    Been watching some warehouses with bigger panels go up on my daily commute. Almost every job I've been by, is using cranes with 100-150' booms to minimize moving the cranes between section picks.

    That is so sad that Heavy Machinery like crane collapse and takes life of People. Sometimes useless heavy Machinery equipment become the reason. One must limit the risk of accidents and use crane overload indicator. You may order the multipurpose i4000 crane load indicator systems from Crane Warning systems Atlanta.

    Plain ignorant when someone uses a tragedy to try to sell a product. Pay for your advertising!! You will catch negative advertising spamming the forum

    Trying to sell a 14,000 lb. load indicator. Not even relevant. Boycott the product. .

    But that crane was able to lift many previous walls, I think a shackle snapped, caused the overload.
