起重机崩溃：它可以再次发生吗？

由于咆哮的风带，最后一颗叶子和强大的阵风送垃圾桶滚动，所有这些建筑起重机将如何在哈利法克斯天际线票价？

在热带风暴后坠入街市的公寓里，起重机的回忆是人们的思想。在散落于哈利法克斯地区市政府的建筑地点，他们正在紧张的回忆，考虑到大约有26只塔式起重机“吹风”。

幸运的是，2019年的68吨吨起重机的崩溃发生在野外和暴风雨周六下午，当大多数人在家里亨克拉德和它的建筑物倒在占用的建筑物上时，所以没有人受伤。

The province paid out $2 million to clean up the mess, while the lawsuits brought by businesses and individuals whose lives were disrupted continue to wind through the courts.

虽然预计Winds将在两年前达到97公里，但是起重机建造了一个小时，以承受160公里的风。预计不会在邻近的13层级的公寓楼内失败，并由WM Fares Ltd.正在建设中抵消

起重机的凹陷和堕落的原因 - 如BMR结构工程为劳动部开展的报告中所识别的 - 在起重机下部有缺陷焊接，底部6-9米。在塔中也识别出其他缺陷的焊缝。

Despite that finding, BMR determined the crane was properly prepared for the storm and that it was set in what’s referred to as “weather-vaning mode,” where the brakes come off and it rotates according to the direction of the wind.

调查发现，经营起重机的公司已遵守加拿大标准协会和NS劳工处所要求的检验和程序。

In the conclusion, the Labour Department promised to review the findings with crane operators and “engage industry to develop and implement an industry-leading code of practice or standard for enhanced tower crane mast and boom weld inspection, testing, and maintenance in Nova Scotia.”

Walking the talk?

周一联系Nova Scotia劳工处揭示了没有为检查繁荣和桅杆焊接的“实践守则”。

The report’s findings were reviewed with crane operators, according to Khalehla Perrault, spokesperson for the Department of Labour. Perreault said; “requirements for cleaning, inspecting, maintaining and repairing tower cranes were communicated”, and, “a third meeting is to take place before the end of the calendar year.”

Perrault says the Canadian Standards Association will release a revised safety code for tower cranes next year. Don Ehler, the Chief Inspector of Crane Operators for Nova Scotia, has a seat on the CSA’s Technical Committee for Tower Cranes (a first for this province).

哈利法克斯审查员询问劳工处采取的行动，以确保在周一晚上在周一晚上的风雨预测之前检查和安全地保护起重机。佩鲁尔表示，NS劳工处有36名职业健康和安全官员，所有这些都是忙着联系全省的建筑工地 - 有没有起重机的人 - “确保所有起重机，设备和碎片都安全和安全。”

In an email, Perrault also set out the process crane operators are supposed to follow on construction sites. She said before a tower crane can be placed in service, all structural elements must undergo a non-destructive test as well as a load test. “An engineer is required to certify the crane for use based on these tests,” she wrote. “After the crane goes into service, it must be inspecteddaily（审查员的斜体）。所有结构组件必须由合格人员每月检查。例如，由劳工处的技术安全部门许可的起重机运营商。工程师必须每年证明起重机。“

在过去的12个月里，佩鲁尔表示，劳工处已向起重机公司发出两项罚款，以符合不合规。
