Q:What is the difference between a tower crane QTZ31.5 and a QTZ40?
Lifting moment, arm length, elevation is not the same ah! Specifically, the maximum lifting weight of QTZ315 is 3 tons, the length of the arm is from 38-42 meters, the elevation is 27-28 meters; the maximum QTZ40 is 4 tons; the length of the arm is 42-48 meters; the elevation is 29-32 meters.
Q:a question about ichabod crane? ten points!?
Here is a simpler way to describe how he looked. tall but exceedingly lank Narrow shoulders long arms and legs hands that dangled a mile out of his sleeves feet that might have served as shovels whole frame loosely hung together head small, flat at top huge ears large green glassy eyes long snipe nose spindle neck (later compared to a grasshopper because of his posture on horseback trying to get away from the headless horseman.) He wasn't exactly ugly. He was full of himself. He thought he was the smartest person in town. He took advantage of people. (all but Katrina, who took advantage of him.) He also believes in all the myths, legends, and tall tales to be taken literally. He is frightened by anything that reminds him of ghosts or demons. That is why he is so frightened by the headless horseman. Hope I helped. I am also reading the legend of sleepy hollow at the moment for school. I have to do an essay on what he looks like and acts like. So I looked it up and found this. Hope it helps you.
Q:How has Stephen Crane influenced authors and writers?
I'd mention his book Red Badge of Courage and how it changed the war novel for American and English writers. You can look at books like Catch-22 , MASH, or Hemingway's war novels and find that personal voice that Crane used.
Q:how many different types of cranes and winches are there?
A bit more information might help. In England there are Winches and then there are winches. As for Cranes are we talking about birds.........actually there are only a few type of each.......but there can be quite a few variations of the basic types. let's say 6 types of cranes and 4 or 5 winches.
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:What is Whooping Crane in French?

Q:Calculate Work Done by a Crane?
The total work done by the crane equals the potential energy gained by the wrecking ball and the cable; the potential energy gained is W = V_final = Mg L + ρ L g L/2 which is the final potential energy of the wrecking ball and the cable added together. In the case of the cable, you take the center of mass of it which is located right at the center (L/2). The result is then W = 3000*32*40 + 10 * 40 * 32 * 40 / 2 = 4096000 ft-lbf = (4096000)*(0.001285067) BTU = 5263.63 BTU
Q:What measures should be taken to make tower cranes stable?
The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3 times of the same structure light steel wire rope (laboratory comparable conditions), not easy to wear and corrosion is not easy to cause the service life of wire rope large amplitude extension. Manganese phosphating is wear resistant phosphating, which can solve the wear problem in the use of wire rope and improve the corrosion resistance. It is for reference only
