TOWER CRANE QTZ4 hydraulic tower crane with swing top, horizontal jib and mobile trolley

Q:Secured to a concrete floor with 12 30mm bolts: That can only be answered by analizing it. A crane as you are supposed to know has different loads and directions of impact due to the moving bridge, the trolley, and break loads. So what it can lift depend on the whole structure. Besides depends as much on the type of crane

Q:I've only read Hunger Games and watched the movie and noticed a large presence of Seneca Crane in the movie.However, I don't recall him being mentioned in the Hunger Games? Is he even mentioned in the Hunger Games? If so, please provide pages.I know he is definitely mentioned in Catching Fire but I haven't read that yet.: Crane and Snow get some extra screen time vs. the book. This helps to explain the HG universe to people that had not read the books. It also sets the stage for the changes to the Games / head gamemaker in the next film. I'm pretty sure Katniss does not find out his name until the next book.

Q:So I have this teacher for almost 4 years and I didn't very much liked her style of teaching. During my sophomore year I was getting fed up with having her in my favorite class. Unfortunately she got ovarian cancer. Now that I think for what she has done and not acknowledging her, I feel really bad. To make things up I wanted to give her I guess the 1000 cranes before I leave for college.Is it okay to give it to her? If so, what do you do once you have all 1000 of them folded?: You string them in combination in order that they nest in combination in a protracted garland, after which fold the garland smartly in a field. It might definitely be ok to ship them--in particular for the period of a excursion for decorations-- despite the fact that the special location you might ship it might differ from location to location. I might additionally advise drawing near the media, your loved ones, peers and colleagues and asking them to sponsor cranes, in order that you're sending cash at the side of your thousand cranes. I'm folding cranes for charity. You can sponsor one for 5 greenbacks. Would do the trick, and it might upload to a symbolic gesture.

Q:Does anyone know where I can locate a print or lithograph of the chromolithograph done in the 1850's of William John WIlgus' Ichabod Crane and the Headless Horseman?: Ichabod Crane, Respectfully Dedicated to Washington Irving. by William J. Wilgus, artist chromolithograph, c.

Q:I know that you have to unfold the origami paper crane, but how do you find the surface area of it???????????????????????????/ please help...........: Do you remember the formula for determining area? For a flat object (like your paper) the formula is Length X Width = Area. or LW=A So unfold your paper, and measure the length and the width, and simply multiply the two numbers. The resulting number will be your area. Of course, that is the area of the unfolded paper. Your crane in it's folded form will have a much different, and harder to find, surface area value.

Q:single shard pls need awnser quick 8th grade lit test: Crane-man is a kindly old man with a crippled and useless leg. Crane-man takes care of Tree-ear and loves him very much. Crane-man can only walk around with crutches, but he still had the upper body strength of a young man. Sadly, at the end of the story, Crane-man dies of a heart attack when he falls into the river next to the bridge and the freezing water kills him. Crane-man outlived all of his family and friends, and unable to work, he was forced to sell all of his possessions, and eventually he ran out of money and came to live under the bridge. A crane, besides standing on one leg, is also a symbol of long life, and this is how Crane-man got his name. Throughout the story, Crane-man displays his generosity and kindness towards Tree-ear, Min, Min’s wife, and other villagers. the link below provides a full synopsis of the book

Q:Are Crane Flies Venomous?: Crane flies are non-venomous and non-biting .It is a common myth that the daddy long-legs would be the most poisonous animal if only it knew how to use its poison, but this is false. There are 300 species in Britain with the commonest being the entirely harmless, if annoying, Tipula Paludosa. They are completely harmless and only live for around three days as adults.

Q:A crane operator was extended his Tadano crane boom(two section of boom out of five) at almost 0 degree boom angle. My question is-Is it safe to lift any load at 0 degree boom angle.: I suppose Tadano is the manufacturer and they make several models most of which are safe at zero degrees with two sections extended. The weight of the extended cable and hook need to be added to the weight being lifted or lowered, so the allowable weight could be zero for a very long cable. Some safety factor is present, so you may choose to push your luck. A cable that breaks suddenly can whip around in a dangerous manner. If you bend the boom replacement will be very costly. If the boom was bent in a previous lift, it is much weaker than an unbent boom and the extending feature may jam. Neil

Q:Absolutely bs. I hope a crane falls on ALL these effin construction workers and their families and the building executives' heads. Let THEM have family members die or get hurt from these accidents - then they will get what's coming to them. They should all burn in hell. Total greed total total greed. They will pay: It's not really the construction workers fault. It's the city inspectors!! They take short cuts, sign off on inspections that never happened, all because of greed! Then they can say they inspected them and go home early. Unfortunately it's the innocent residents of these buildings and the construction workers that die while they are at home all snug in their beds!!! That first crane accident should have taught them all a lesson, but evidently it did not. I think whoever was in charge of inspecting that crane should be arrested for manslaughter. The first guy got in trouble, I'm not sure to what extent but it obviously didn't make an impression on the rest of those lazy a**holes!
