在达拉斯的一个暴风雨周日下午,阵风为70英里 /小时。塔架绑在一个新的公寓楼框架上,砸碎了其后面的一个完整的停车结构。其他部分通过一座完整的公寓楼撕裂,杀死了29岁的基尔森·西蒙森·史密斯(Kiersten Symone Smith)。

6月9日,起重机事故的糟糕一年变得更加严重。4月27日,一次塔式生气故障杀死了西雅图的两名铁工和两个路人。该事故仍在调查中,重点是拆除程序。

最新的事故可能会将更多注意力集中在塔 - 强化风能弹性上。媒体媒体采访的起重机专家和调查人员谈到了将Tower Cranes无烤制并在大风中自由吹制风雨的重要性。2018年10月,来自职业安全与健康管理局的联邦调查人员报告说,SK-315 Hammerhead起重机在迈阿密飓风Irma期间的吉布斯摔倒了,可能是由于动荡的风向猛烈的向上而施加了猛烈的副部队。

Exactly what model of tower crane fell in Dallas, and what wind loads it was subject to, are unclear. An attorney for Bigge Crane and Rigging Co., which supplied the crane and its operator to the project as an equipment rental provider, confirmed in a statement that the crane was not being operated when the storm hit. But the San Leandro-based company did not release any additional information about the crane model or its condition. The attorney said that the fallen crane sections, which remained embedded in the partially destroyed building sections and had forced the evacuation of the apartment residents, would remain where they fell until OSHA completed its work at the jobsite.

Greystar, the developer of the new building and the owner of the existing ones, could not be reached for comment on the tragedy or the aftermath for the project team.
