Q:Military Action movie with bunch of cranes at the end?
Cranes like construction equipment or Cranes like the birds?
Q:How often should the crane be inspected regularly?
Crane safety supervision regulations twenty-fourth in lifting machinery safety regular supervision and inspection cycle for two years, elevator and manned elevator safety regular supervision, inspection cycle for a year.Eighteenth lifting machines should check the lifting machines regularly, including annual inspection, monthly inspection and daily inspection:I. at least one full inspection shall be carried out annually on the lifting machinery used.The load test can be carried out by lifting the heavy load which is equivalent to the lifting weight, and checking the safety performance of the mechanism such as lifting, running, turning and amplitude according to the rated speed.Lifting machines which have not been used for more than one year should be examined comprehensively before use.Crane in case of four or more earthquakes or major equipment accidents, outdoor work crane after more than nine winds, should be used before a comprehensive inspection.
Q:Could bird cranes resemble angels in appearence?
Hi, I really don`t see how,Angels do not always appear having wings nor do they always have a solid appearance,sometimes they appear ethereal, I think that if you ever saw an Angel you would instantly know its reality.
Q:Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
the requirement for selecting the steel quality group based on the results of brittle fracture evaluation of steel is increased;Environmental requirements and nondestructive testing requirements for welds are increased;- increased the number of institutional requirements;- increased the type and requirements of some of the units;- - increased technical data requirements that manufacturers should provide;- added some information labeling requirements;- mounting and climbing requirements are increased;The inspection requirements of tower crane are described in detail.
Q:Any difference?
The crane part can be identical, but the vehicle part differs: in the former case it's a road-going (even multi-axle) truck, in the latter case it's an off-road vehicle with oversize all-terrain tires and appropriate traction and transmission capabilities. In either case, the vehicle must be stabilized on adjustable hydraulic struts before hoisting.

must be sble to left one in half times weight
Q:Question says it all. On the Yahoo homepage, there is a breaking story that you can not click on, stating the NY fire department are responding to a building collapse, but when you try searching it, only a story about a crane comes up in Yahoo search engine. Anyone know if it's 2 different stories or the same thing?
Yes there was a fire on a 4 story buildilng 8th and 14th St. The outer facade of the building collapsed. The fire dept was fighting the fire. Then they've got a crane on a highrise that is dangling. They said they have to get inspectors to climb the 74 stories of stairs to go inspect it. Now they are also saying it's an extra tropical storm with a cold core which turned it into a super storm. Everyone thinks the eye came in but no it reformed and eye has not come in yet the weather service said. If it combines with all that cold arctic air more people are going to get blizzard like conditions.
Q:Hi friendsI need some sketches of automotive crane?In which site or web log I can find it?
I'm not sure what you mean by an automotive crane: a tow truck, a crane for lifting car engines, or a crane for lifting cars. Anyway, try google images. Search for automotive crane and see what it turns up.
