Here is a picture that we recently took in the field. Another contractor tried to use a standard anchor to attach heavy x-ray imaging equipment overhead to a precast concrete (hollow core or flexacore) deck. The cone shaped hole is a sign that the anchor selected was not appropriate due to the weight of the equipment and the construction methods used to create the concrete deck. This anchor failure and resulting accident could have, and should have been avoided. Fortunately, no one was hurt.
