1、Crane Work Needs More Technique Abstract Crane work needs more technology. Construction of tower cranes are the main vertical transportation equipment and also a measure of construction companies and equipment strength of the important logo, in todays increasingly competitive construction market, to
2、 meet the construction needs of many construction companies have bought the tower crane. With the tower crane at the construction site of the widely used by the tower crane accident also caused more and more to peoples lives and property brought about great losses. According to national statistics,
3、the departments concerned, the tower crane accident rate reached 2.77 percent. Its security problem is still the urgency of the construction Loose training, testing and oversight requirements for the people who work around construction cranes have fostered a false sense of security in our industry.
4、The recent deadly tower-crane collapse at a congested New York City building site should be a wake-up call for us to question and step up our current safety practices. Training and testing is king when it comes to safety. But the construction industry is putting unqualified personnel in the seats of
5、 construction cranes, even with todays testing. In many places, no experience is necessary after passing a standardized test. One week of study will give some people enough knowledge to pass a certification examination, and then they can jump into the cab of a crane. Imagine that a commercial airlin
6、e pilot had the same training as a certified crane operator. How would you feel the next time you decided to fly? In California, it takes more hours of training to wield a pair of scissors in a hair salon than to operate potentially dangerous lifting machinery. How does this make sense? Riggers and
7、signal persons also need standard training and testing to ensure safety under the hook. Employers usually allow any craft to signal a crane on a jobsite, despite best practices that require only qualified people do so. How is it then that uncertified and untrained people are allowed to signal and ri
8、g under the hook of a licensed or certified operator? Tower cranes are particularly risky as urban sites become more congested, and the risk of a catastrophic event is very high during climbing operations. Yet most tower-crane climbing crews are trained in a non-traditional manner, via secondhand kn
9、owledge that has been passed down over time. The problem with this type of hand-me-down knowledge is that it changes over the years, leaving out small-but-important details along the way. This “osmosis“ of knowledge leads crews to develop their own tricks for climbing cranes, often forsaking basic s
10、afety in an attempt to save time and energy.In many cases, there are no safety devices or alarms to warn of a serious problem. Climbing crews are subjected to pressures that affect safety-critical decision-making. It is not uncommon for climbs to continue with damaged or leaking hydraulic systems, o
11、ut-of-adjustment or jammed guide rollers, often working in the dark and for extended hours. This “MacGyver“ method of climbing, where every jump becomes a new adventure, should not be the norm. Climbing-frame designs vary among manufacturers, but the operational steps are similar in principle. The c
12、limbing process is relatively straightforward, with a mixture of physical work and technical procedure. It is not complex; it is more about knowing the proper sequence of what needs to be done and then following the steps, one by one, making sure each step has been successfully completed before movi
13、ng onto the next. It is essential that everyone know exactly what is going on and what the dangers are at every stage. Thats why the industry needs standardized training, testing and oversight for this work, including a practical assessment of competence. Technicians should have model-specific train
14、ing directly from the manufacturer, along with a level of practical experience. Inspectors, too, should be required to have specific technical training. They should be independent from all aspects of installation and maintenance to allow for objective decisions. Key personnel on erection crews shoul
15、d have standard training and testing. When these needs are satisfied, crane operations should be carried out in strict accordance with the manufacturers instructions, engineering principals and governmental laws. But industry stakeholders and lawmakers need to step up their lax standards to protect
16、the public. New York City residents, who have seen their homes turned into dust and debris, would be shocked at the way the industry deals with these issues. 起重机的工作需要更多的科学技术 摘要塔式起重机是建筑施工垂直运输的主要设备，也是衡量一个建筑施工企业装备 实力的重要标识，在当今竞争日益激烈的建筑市场，为满足施工需要，很多施 工企业都购置了塔式起重机。随着塔式起重机在施工现场的广泛使用，由塔式 起重机引发的伤亡事故也越来越多，给人民的生命财产带来重大损失。据国内 有关部门统计资料表明，塔式起重机的事故率已达 2.77%。其安全问题仍然是 建筑施工中的忧患起重机的工作需要更多的科学技术松散的培训，测试和监督的要求, 周围的建筑起重机给这些工作的人树立了一 种虚假的安全感，在我们的行业。最近塔式起重机倒塌
