Q:how to become a mobile or tower crane operator?
You have to be able to do simple trig to figure what your crane is capable of. You will have to become a member of the crane workers union. Someone may have to die to make a space for you. You may have to take jobs that are just fork lift qualified, if you are lucky, you might find work at seaports unloading cargo ships.You may have to work your way up through the ranks as a wrecking ball operator. The very lucky will make 50-60K +. The really good ones will make more only after many years.
Q:what is so ironic about the open boat by stephen crane?
What is ironic is nature. This is a correspondent who has covered wars etc. and now his enemy is the sea - nature. What is also ironic is that nature has no regard for class. We know people on this boat come from very distinctly different classes. And yet, the ocean threatens to kill them all, just the same. Kind of like on the Titanic. Rich and poor alike lost their lives. The answer is that nature is the ultimate foe, and when it wants to, it always wins or sure tries hard enough to win. That is what makes this story a beautiful example of American Romanticism. Pax-C
Q:Who invented the tower crane, please?
Tower crane originated in Western europe. The first patent on tower cranes for construction was issued in 1900. In 1905, a crane with a boom was fixed in the tower. In 1923, a prototype of modern tower crane was built. The first relatively complete modern tower crane appeared in the same year. Our tower crane started from Shanghai in 1950.
Q:What is the difference between Fujian White Crane Kung Fu and Wing Chun Kung Fu?
White Crane Kung Fu
Q:Are sandhill cranes edible?
yeah, but they are a little tough and taste sort of like Mexican Spotted Owl
Q:What is the significance of the white doves and the crane in the book Sadako?
Anyone who folded a thousand paper cranes would be granted a wish. Sadako wished to healthy again so that she could run and play like before, and she pursued her goal with such determination that, although she died of her disease, she succeeded in transforming the paper crane into a symbol of peace for children all over the world.
Q:How much more than m of tower crane jib winch point height should be equipped with anemometer
According to the regulations of JGJ196-2010 for the safety and safety of installation, use and disassembly of tower cranes for construction purposes:The use of 4.0.15 tower crane height of more than 30m should be equipped with obstacle lights, jib root hinge height of more than 50m should be equipped with anemometer.
Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?
As for the reasons, the main consideration is the actual needs.
Q:Two cranes can unload a ship together in 8 hours. The faster crane takes 12 hours less than the slower crane,?
Fast Crane = A unload x /hour Slow Crane = B unload y /hour A + B = 8 hours x /hour + y /hour = 8 hours (average rate) average rate = (x + y) / 2 so 8 hours = (x + y) / 2 and x + y = 16 since the slow crane is 12 hours longer, x must be 2 hours, since they will both take 2 hours and the slower crane will take 2 hours plus 12 hours equalling 14 hours. The rate of crane A is 2 hours to unload and the rate of crane B is 14 hours to unload. The average rate for both to unload is 8 hours. There were certain assumptions made to solve this puzzle and it is not clear how they actually operate on the ship while unloading. ~~ The most practical way to unload the ship is *NOT* to use the slower crane since it takes longer for them to work combined, than for the faster crane to work alone !! A tricky but fun question !! :-b
Q:How does a climbing or tower crane work?
They add extra stages from the bottom. A tower crane is erected from a boom assembly, first and second tower sections of different cross section, and a base in a sequence of steps in which the boom assembly is mounted on a hollow climbing section dimensioned to be received in each of the larger second tower sections and defining a cavity dimensioned to receive each of the first tower sections. One of the latter is secured on a base in upright position, and the upright section is received in the cavity of the climbing section which is then raised relative to the first section and enveloped by one of the second sections. The enveloping section is secured to the base and the raised climbing section for supporting the climbing section whereupon the first tower section may be released from the base, raised, and secured to the second tower section. The climbing section may then be raised relative to the first tower section to permit the installation of another second section, and the procedure repeated, until all second or larger tower sections are superimposed on each other, the one first section being ultimately attached to the topmost second section. When the climbing section is raised relative to the attached first section, another first section may be superimposed on the one first section and the procedure repeated until the slimmer portion of the tower is assembled from superimposed first sections. Ultimately, the boom assembly is attached to the topmost first tower section, and the climbing section may be removed or stored for further use on the wider, lower tower portion.
