Q: I am doing uni coursework to design an ergonomic layout for an operator cab for a tower crane and so I need to list the required operator controls.Thanks!
There are only two control levers that are on a tower crane.There is one on either side of the seat called joy sticks the right side joy stick controls the hoist cable to go up and down pushed forward to go down and pulled back to hoist up.The left has four functions it controls the swing of the crane and also the boom of the crane to control the swing you push the lever to the left to swing left and push the lever right to swing right.You pull the lever back to boom up and puh it forward to boom down.
Q: I was half way through this book and had to stop reading it because school got in the way. I'm back to reading it and I got to the part where Katniss made a noose and tied it around a dummy and showed it to the Gamemakers. And she wrote 'Seneca Crane'. I don't remember who that was. If it was even a person, I guess it was. But can you just explain who or what 'Seneca Crane' is and why Katniss would do that? Thanks.
He was the previous head gamemaker, and President Snow basically declared that he had Seneca Crane executed. Crane allowed Peeta and Katniss to live and cut off the final moment of the berries, which to Snow was an act of defiance. I think Katniss hanging the doll was just a symbolic act, implying that the gamemakers are really all just puppets under the Capitol.
Q: Cranes are normally used in construction in most countries.But I saw some photos that show Iranians are hanging criminals in pubic with cranes instead of gallows.Is it more painful to the dying criminals to the last moment?Do you know why?
they probably didn't have the proper arrangements to carry out the punishment so they used cranes instead of gallows. who knows? but weird really. and it wouldn't be more painful... err... the purpose is to snap the neck... ouch :(
Q: i read this comment on youtube about people making 1000 paper cranes for japan is this a real thing like can i make paper cranes and mail them to some place if anyone knows the details you would be helping me out because i already started making paper cranes and its such a small but beautiful thing plz help
nicely first of all, i notably advise that purchase some Anti-Pope spray basically in case you have jesus christ knocking at your door. Then i opt to advise which you're making a cake. ideally , a banana, because it quite is my typical. And deliver it to me in the mail. via now, i'll bless you that your place and family individuals besides as acquaintances, are all wanted nicely and which you're no longer killed from one in each of your paper cranes stabbing you in the attention. I additionally advise getting life coverage. God purely is familiar with how sharp paper is and it rly rly hurts. Then devour some poultry, Avacado Sushi via fact each physique is familiar with it quite is techniques nutrition. I end off via commending you and via saying. See you on monday.
Q: I was wondering how those guys/gals get up to their posts. Is there some type of elevator or do they climb up everyday? I'm talking about those big cranes on contruction sites. the huge ones.
There are ladders leading up there. Crane operators are fit enough to do the climb at least twice a day. I climbed cranes on weekends as a hobby photographer to take panoramic shots from that nice position up there. It was quite a climb to get up more than 200ft (60m)
Q: What was the mekhane (crane) used for in Greek plays?To remove scenery between actsTo lift the king and his court to their viewing boxFor actors playing the godsIt was only used in building and tearing down the set
For actors playing the gods. The Greeks loved theatre, and just like today, there were cheap productions with little merit or wothiness for remembrance. In these cheaper plays, the creators would try to appeal to the people's religious convictions by having one of the gods (usually Zeus) descending from heaven to resolve the conflict and set things right. To present this in theatre form, the actor would be lowered down to stage on a crane in order to simulate the god descending from heaven. This became such a tired cliche in ancient Greece that the phrase Deus Ex Machina, which translates to God of the Machine, has come to mean An unexpected, artificial, or improbable character, device, or event introduced suddenly in a work of fiction or drama to resolve a situation or untangle a plot.
Q: do they start with the crane house and keep adding sections underneath it? Or do they build they tower and then somehow top it with the actual crane?
As described above, but the crane that is being used in our plant arrived in 80 semi truck loads!
Q: If you make 1000 origami cranes is it true that you will get a wish or good luck. This is based on a Japanese myth
It's like asking: If you make a wish on a shooting star, will it come true? Although both are nice gestures, no it will not come true. Origami cranes are simply pieces of paper that are folded to resemble birds; no matter how many you make, they will not take on supernatural abilities such as wish-granting.
Q: In Catching Fire Katniss hangs a dummy with the words Seneca Crane on it. Who is that? It sounds familiar...
The Games maker for the 74th Hunger Games.
Q: Which one is a better investment? I can get both for 200dollars
Hi JAY ... Neither is a large investment compared to the time and work using them involves. Lifting an engine requires a lot of work getting stuff disconnected and , even worse, reconnected when put back. Of the two, I believe the crane would more useful. When considering such projects, you should take into account all your work and time the project will take. Whatever, I wish you the best.
