- Q:Emergency treatment of interrupted electricity during lifting of tower crane
- It is very dangerous to stop the electricity during the lifting of tower crane. Because the slewing brake is missing, the tower crane is very dangerous because the wind rotates.
- Q:What do the words neck-craning and neck-straining mean in the sentence below?Sports cars are often designed to make a statement, and many of the newest models do that with neck-craning styling and neck-straining performance.
- 'Neck-craning' in this context I think means to crane your neck around to see all angles of the presumably beautiful styling. Neck-Straining in this context I imagine refers to the G-Force experienced from acceleration provided by the high-performance sports-car.
- Q:I was wondering if Steam Cranes are still used to clear train derailments or are the all mothballed now? What do they use to clear derailments now days if the not the Steam Cranes? Also way are there 2 types of hooks on the crane anyway? Thanks
- No, they don't. They have to use road cranes - think of the accident at Grayrigg some while back. They had terrible trouble clearing the line as heavy lifting equipment had to be brought quite a distance over muddy fields. I seem to remember special temporary roads had to be laid. Similarly with the freight accident in Scotland a few weeks back, roads were closed, again whilst wreckage was cleared.
- Q:Please help. I need real answers.
- About Ichabod Crane, the school master, Washington Irving writes in A Legend of Sleepy Hollow: He was, in fact an odd mixture of small shrewdness and simple credultiy. His appetite for the marvellous, and his powers of digesting it, were equally extraordinary; and both had been increased by his residence in this spellbound region. Ichabod Crane digests Cotton Mather's (a Puritan preacher) History of New England Witchcraft, a book in which he firmly and most potently believes. He spends many hours reading Mather's work, and fluttered by his excited imagination he believes that he is struck with a witch's token at times. To drive away the evil spirits, he sings psalm tunes. Nevertheless, Crane still delights in the supernatural, so he spends winter evening with the old Dutch wives who exchange tales of ghosts and goblins around the fire. In turn, Ichabod entertains them with Mathers's reports on witchcraft, as well as predicting what the sounds in the winter air portend.

- We start using by defining mechanical Power: = P=Work/time What is the work here? We lift the box a given distance. Work=mgh Since we know the power of the crane, we can simply plug in the values and solve for t: t=mgh/P This is only true if the crane has a constant power, which seems to be the case LeSmartOne
