- Q:How many tons of tower crane QTZ80A lifting?
- Lifting torque = mass * radius of gyration (amplitude). That is to say, the bigger the weight is small.
- Q:A site would be nice...
- For themes, I wrote Fast Rode the Knight, written by Stephen Crane, is a short poem about a knight going into battle, and his forgotten horse. Some themes in this poem are love and devotion, battles in war, the passion that drives the soldiers, or knights, into it, the forgotten aftermath of the battles, and what has to be left behind for such a battle to be fought. The passion of the knight can be found in the lines Ever waving an eager sword/’To save my lady!’. The knight rides at a furious pace, driven by love and a blinding devotion to his love, or perhaps his Ruling Lady. thats just like the beginning, hope it can help you :D It's not nearly finished, but hope it is okay all the same :)
- Q:I was told that this was taking place, so i would like to fax the info to the proper local
- Is it a seeing eye dog?
- Q:Cranes nowadays are MASSIVE! but something that has been bugging me for ages is how do they get the massive crane bit at the top down once they have finished constructing the skyscraper/building?
- After this the crew uses a mobile crane to assemble the jib and the machinery section, and places these horizontal members on an approximately 40 foot mast that consists of two mast sections. The mobile crane then adds the counter weights. The mast which is a large triangulated lattice structure typically 10 feet square then rises from this firm foundation. This triangulated structure gives the mast the strength to remain upright. The tower crane rises to its maximum height by using one mast section at a time, the crew uses a top climber that fits between the slewing unit and the top of the mast. This is done by hanging a weight on the jib to balance the counter weight. The crew then detaches the slewing unit from the top of the mast, this is done by using large hydraulic rams in the top climber to push the slewing unit up to 20 feet. The crane is then used to lift another 20 foot mast section into the gap opened by the climbing frame. Once bolted in place the crane gains a height of 20 feet. This process is reversed once the building is finished and its time to dismantle the crane and as stated earlier a smaller crane is used to dismantle the tower crane except the mast which is dismantled by the crane itself
- Q:Do cranes play major role in Japanese culture? How so? Do cranes live in Japan?
- Red-crowned cranes (also known as Japanese cranes and Manchurian cranes) breed in Siberia and Mongolia during the spring and summer but migrate in flocks to Japan, Korea, Taiwan, China, and other East Asian countries for the winter season. They are the second rarest crane in the world, and it is known as a symbol of good fortune, longevity, and fidelity in these countries. In Japan, they are considered to be a national treasure. They frequently appear in art, literature, and folklore. I remember a tale about a lonely man in winter and finding a crane nearly dead in the snow. He nursed the crane in his home until it was well enough to fly away on its own. The next winter, the crane came back as a beautiful maiden wearing the finest red and gold silks. She promised to live with his man and weave silks for him to sell. The only catch was that he was to never look at her while she was working. They lived happily for a while, until one day he couldn't hold in his curiousity any longer. He took a peek behind the screen and saw a crane weaving silk with its feathers! Naturally, the crane noticed and flew away, never to return. In Japan, cranes are said to have the legendary lifespan of 1,000 years (hence, the folding of 1,000 paper cranes). Cranes are also known to mate for life, making them a popular motif at weddings and anniversaries.
