Lifting Matters Issue 12 March 2010

  1. 1. READERS LETTERS Dear Sir, I have just read the editorial artical (sic) in the latest edition iof (sic) 'Lifting Matters'. In the second paragraph there is a statement, see below, that is incorrect and misleading; "Under the standard, cranes are required to be checked periodically every three months, with major certification and refurbishment compulsory at 10 years for mechanical and 25 years for structural inspection to assess their suitability for continued safe operation." LIFTING MATTERS I have reproduced the actual wording from Section 7 of AS 2550.1 7.3.5 Major inspection The following cranes shall be subjected to a major inspection to assess their suitability for continued safe operation: Published in the interest of promoting safety in the crane industry (a) Cranes that have reached the end of their design life or, where this is unknown, after 25 years for the structure and 10 years for the mechanical components. NOTES: 1. A crane’s design life may not be the same as its actual life and depends on such factors as its classification, usage and its operating environment. Sharing an d Learnin g As can be seen the limiting factor is the 'Design Life' of the crane not a calendar period. A particular crane may not reach its 'Design Life' for a period exceeding 50 years depending on its usage or conversely a crane that is used in a high intensity application may reach its 'Design Life' before it is 10 years old. It is therefore important, in my view, that crane owners and regulators have a clear understanding of what AS 2550 actually states, not the simplistic statement given in the publication provided, because it could lead to serious accident/s if a crane exceeds its design life and remains in service because of a misunderstanding. This may lead also to an expensive lesson if such a matter proceeded to a prosecution after an accident. Regards Rex Clark Past Chairman of the ME/5 sub-comittee (sic) responsible for development of AS 2550 (Letter shortened due to space consideration—RDP) To err is human; to blame it on somebody else is even more human.” - John Nadeau Colonoscopy All the organs of the body were having a meeting, trying to decide who was the one in charge. "I should be in charge," said the brain , "Because I run all the body's systems, so without me nothing would happen." "I should be in charge," said the blood , "Because I circulate oxygen all over so without me you'd all waste away." "I should be in charge," said the stomach," Because I process food and give all of you energy." "I should be in charge," said the legs, "because I carry the body wherever it needs to go." "I should be in charge," said the eyes, "Because I allow the body to see where it goes." "I should be in charge," said the rectum, "Because I'm responsible for waste removal." All the other body parts laughed at the rectum and insulted him, so in a huff, he shut down tight. Within a few days, the brain had a terrible headache, the stomach was bloated, the legs got wobbly, the eyes got watery, and the blood was toxic. They all decided that the rectum should be the boss. The Moral of the story? Even though the others do all the work.... MARCH 2010 The ass hole is usually in charge ! 12 LIFTING MATTERS March 2010 LIFTING MATTERS March 2010 1

  5. 5. New York Crane owner expected to be charged with manslaughter in 2008 Upper East Side crane Collapse The owner of the city's largest construction crane company is expected to be indicted for manslaughter in the death of two work- ers killed in an upper East Side disaster nearly two years ago, James Lomma, owner of New York Crane and Equipment Co., and a top aide identified only as Tubor, could be charged by Manhattan District Attorney Cyrus Vance as early as Monday, sources familiar with the investigation told The News. Lomma, whose companies have contracts at Ground Zero and dozens of other sites around the city, owned two massive tower cranes that collapsed in 2008 -- one on E. 51st St. on March 15, the other on E. 91st Investigators sift through the devastation for clues in the May St. On May 30 --killing a total of nine people. 30, 2008 crane collapse on E. 91st St. Lomma is being charged only in connection with the deaths of the two workers killed at 333 E. 91st St. disaster, the sources said. The District Attorney's office declined to discuss the case. Lomma is the only person to be prose- cuted so far in connection with the crane disaster deaths. A building inspector, Edward Marquette, was indicted for faking inspection of Lomma's crane on E. 51st St. The dual collapses forced the resignation of Buildings Commissioner Patricia Lancaster and ex- posed bribery, corruption and incompetence in the troubled agency's cranes unit. In the E. 91st St. tragedy, the 30-ton monster crane snapped and crashed in a roar on the street, leaving crane opera- tor Donald Leo, 30, and worker Ramaden Kurtaj, 27, dead in a tangle of steel and broken concrete. Shortly after that collapse, the Manhattan district attorney's office seized records and computers from Lomma's offices and launched a probe into whether the collapse was caused by a shoddy weld that failed, causing the crane cab to shear off from the tower mast. As the district attorney's investi- gation moved forward, the Daily News reported that the Chinese company New York Crane hired to do the welding tried to beg off the project because it was not qualified but ultimately relented when Lomma coughed up more money. The Chinese company agreed to do the job faster and cheaper than responsible competitors. Problems with the doomed crane surfaced a year before the collapse, when workers at a different job site found a crack in its turntable. The city ordered work stopped and the crane dismantled. Beth- any Klein, then head of the Building Department's cranes & derricks unit, revoked the crane's oper- ating papers. But, despite Klein's reservations, the Buildings Department cleared the crane and approved its set up at 91st St. Within weeks of the collapse, Michael Carbone, the inspector who approved the set up, was suspended for neglect of duty. Leo, the crane operator, was set to marry three weeks before he died. His father, Donald Sr., also a crane operator, called Lomma's prosecu- tion "a house of cards that is about to fold." "In answer to the question about how I feel about Jimmy Lomma being taken away in handcuffs, I say it's a start and about time. It will never bring my son back...but it might finally be the beginning of paying real attention to the safety of workers who risk their lives to feed their families." Lomma, who lives in a million-dollar home in Staten Island, was a major force in New York construction and an influential advisor to the city Buildings Department. As a member of the agency's cranes advisory board, he helped draft rules and regulations that gov- erned his own operations and those of his competitors. He has owned contracting businesses in New York, New Jersey, Massachusetts and North Carolina, records show. At the time of the disasters, he owned 11 of the 25 tower cranes in operation in the city. 8 LIFTING MATTERS March 2010 LIFTING MATTERS March 2010 5
