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 today's increasingly competitive construction market, to 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 people's lives and property brought about great losses. According to national statistics, 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 instry. 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 instry is putting unqualified personnel in the seats of construction cranes, even with today's 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 airline 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 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 rig 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 ring climbing operations. Yet most tower-crane climbing crews are trained in a non-traditional manner, via secondhand knowledge 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 safety 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, out-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 climbing process is relatively straightforward, with a mixture of physical work and technical procere. 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 moving onto the next. It is essential that everyone know exactly what is going on and what the dangers are at every stage.
That's why the instry needs standardized training, testing and oversight for this work, including a practical assessment of competence. Technicians should have model-specific training 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 should 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 instry stakeholders and lawmakers need to step up their lax standards to protect the public. New York City residents, who have seen their homes turned into st and debris, would be shocked at the way the instry deals with these issues.
起重機的工作需要更多的科學技術
摘要

塔式起重機是建築施工垂直運輸的主要設備，也是衡量一個建築施工企業裝備實力的重要標識，在當今競爭日益激烈的建築市場，為滿足施工需要，很多施工企業都購置了塔式起重機。隨著塔式起重機在施工現場的廣泛使用，由塔式起重機引發的傷亡事故也越來越多，給人民的生命財產帶來重大損失。據國內有關部門統計資料表明，塔式起重機的事故率已達2.77%。其安全問題仍然是建築施工中的憂患……

起重機的工作需要更多的科學技術

鬆散的培訓，測試和監督的要求, 周圍的建築起重機給這些工作的人樹立了一種虛假的安全感，在我們的行業。最近塔式起重機倒塌在一個繁忙的紐約市建築地盤應敲響警鍾，提醒我們問題的存在，並加強我們目前安全的做法。
當談到安全問題時，訓練和測試是關鍵。不過，建造業是把不合格人員放在建築起重機的駕駛位上，甚至沒有通過今天的測試。在許多地方，沒有任何經驗必須合格的通過標准化的測試。一周的學習將給予一些人足夠的知識足以通過認證考試，然後他們可以跳轉到的起重機的駕駛室。
想像一下一個商業航空公司飛行員和一個認證的起重機操作員有相同的訓練。你會如何感覺，下一次你決定要坐飛機？在加利福尼亞州，掌握一對剪刀在頭發沙龍比操作有潛在危險的起重機械需要更多的時間訓練。如何，這是否合理？
裝配工人和發信號的人也需要標準的培訓和測試，以確保安全下鉤。僱主通常允許任何工人發信號指揮起重機上工地 ，盡管最佳做法是需要合格的人這樣做。怎麼能允許那麼無證和未受過訓練的人來代替有工作證或經核證的操作者呢？
塔式起重機是特別危險的，尤其是在市區用地變得更加擁擠時。攀登行動更是一個風險的行動，其災難性非常高。然而，大多數塔式起重機攀登員的訓練，在一個非傳統的方式，通過二手知識已流傳一段時間。問題與這種類型的現成的知識是，多年來，留下來的非常少，但最重要的細節卻丟失了。這種「滲透」的知識，導致操作者只能發展自己的技巧攀登起重機，往往放棄基本的安全，企圖以節省時間和能源.
在許多情況下沒有安全裝置或警報來提醒嚴重的問題的存在。攀登人員容易遭受到影響安全性至關重要的決策所帶來的壓力。攀登時，使用損壞或泄漏的液壓系統，沒有任何的調整，這並不鮮見。在黑暗中工作和延長工作時間是時有發生的。這種攀登方法，其中的每一次攀登都會成為新的冒險，不應該作為規范被採納。
攀爬架的設計，在製造商之間存在不同，但設計的步驟在原則上是相似的。攀登過程中是相對比較明了的，配合著的體力勞動和技術程序。這是並不復雜，它是更多地了解知道正確的序列需要做什麼，然後按照下列步驟，一個又一個，確保每一步在做下一步前成功完成。這是十分重要，每個人都清楚的知道事情進展的怎麼樣，在每一個階段存在什麼樣的危險。
這就是為什麼業界需要規范的培訓，測試和監督，其中包括一個實際的評估能力。技術人員應該隨著實際經驗的提升，直接從製造商哪裡獲得標准訓練。視察員同樣也也須有具體的技術培訓。他們應獨立於安裝和維修的各方面，這由客觀決定。架設的關鍵人員應該有標準的訓練和測試.
當這些需要得到滿足，起重機作業應進行嚴格按照有關製造商的指示，工程原則和政府的法律。但業內人士和國會議員，要加強他們的寬松標准，以保障公眾利益。看到自己的家園變成了塵埃和碎片的紐約市居民，會對處理這些問題的方式感到震驚。

❺ 想看看機械設計方面英文的書，有沒有好點的，主要學學機械英語，最好是外國的機械設計教材，請推薦一本

可以選擇這本《 Design of Machine Elements and Machines Collins》

以下為其簡介：
Taking a failure prevention perspective, this book provides engineers with a balance between analysis and design. The new edition presents a more thorough treatment of stress analysis and fatigue. It integrates the use of computer tools to provide a more current view of the field. Photos or images are included next to descriptions of the types and uses of common materials. The book has been updated with the most comprehensive coverage of possible failure modes and how to design with each in mind. Engineers will also benefit from the consistent approach to problem solving that will help them apply the material on the job.

Lower and Higher Pairs Connections between rigid bodies consist of lower and higher pairs of elements. The two elements of a lower pair have theoretical surface with one another,while the two elementsof a higher pair have theoretical point or line contact(if wo disregard deflections).
Kinematic Chain
A kinematic chain is an assembly of links and pairs(joints).Each link in a closed-loop kinematic chain is connected to two or more other links.A linkage failing to meet the closed-loop criterion is an open-loop kinematic chain.
剛體間低副和高副連接是由低副和高副元素組成的。低副的兩個元素有相互間的理論接觸面，高副的兩個元素則有理論點或線接觸（如果不考慮偏離）。
運動鏈
一個運動鏈是環節和節點（接合點）的組合。閉式運動鏈中的每一個環節是鏈接到兩個或更多個其他的環節上的。一個未能滿足閉式標準的鏈系是開式運動鏈。

這是關於運動鏈組成的一些基本知識。為了多了解一些關於運動鏈知識的英文資料，你也可以看一下

❽ 《機械設計》英文教材 哪個比較好

同樣跪著等

❾ 有沒有什麼類似高教的《機械設計》、《機械原理》這樣的英文教材求在美國的學長學姐推薦！

根據你的情況，我想到一本我看過的書，叫《機械工程導論》是美國人Jonathan Wickert寫的機械專業學生入門教材，在國內能買到西安交通大學出版社的影印版，很便宜。
本書入門性地介紹了機械工程領域所涉及的一些基本知識和分析問題、解決問題的方法。全書共8章，主要內容有：解決問題能力的訓練；機械零件與機床；結構與流體力學；材料和應力；熱和能量系統；機械的運動和機械設計。各章後有多種類型習題供生思考、練習，篇幅適當，適合我國高等學校機械、能源、動力工程等相關專業的本科一、二年級學生使用。
它的特點：1.涵蓋機械工程主要研究內容；2.英文原版，用詞用語專業地道；3.深度不深，適宜基礎一般者；4.語言生動人性，易於理解且與工程實際緊密結合。
實在是難得的機械專業學生入門的英文好書。
