Q:National standards for tower cranes
Tower crane GB/T5031 - 2008 has been implemented since February 1, 2009. In accordance with the new standards promulgated, chief editor -- China Academy of Building Research Institute of building mechanization of Langfang, Beijing and Hebei respectively in Hangzhou, Nanning held the new standards xuanguan.

Q:what's with a folkfore story about cranes used to deliver babies from house to house?
Well, the story was used to explain where babies come from to smaller children, but it was storks, not cranes, and Im sure it ticked Mother Goose off _ But, the the myth originated in greek mythology see: In Greek mythology, Gerana was an Æthiope, the enemy of Hera, who changed her into a stork, a punishment Hera also inflicted on Antigone, daughter of Laomedon of Troy (Ovid, Metamorphoses 6.93). Stork-Gerana tried to abduct her child, Mopsus. This accounted, for the Greeks, for the mythic theme of the war between the pygmies and the storks. In popular Western culture, there is a common image of a stork bearing an infant wrapped in cloths held in its beak; the stork, rather than absconding with the child Mopsus, is pictured as delivering the infant, an image of childbirth.

Q:a horizontal joist carrying a travelling crane is simply supported over a span of 4m the mass of the crane is 150 kg?
figure shear first Let F be the max. crane load. for a simply supported symmetric load, the reactions at each end support will be half the total load. The reaction loads will also equal the shear load. 3000 N = (F + 150(9.8))/2 F = 4530 N The maximum bending moment will be the shear force times the moment arm of half the joist length 5000 Nm = [(F + 150(9.8))/2] N (2.0 m) 5000 = F + 150(9.8) F = 3530 N The bending moment max load is 1000 N less than the Shear max load so bending is the limiting factor The maximum load allowed is F = 3530 N 3530 / 9.8 = 360 kg As a form of exchange, please remember to vote a Best Answer from your results.
