- Q:why do whooping cranes migrate? If its because its to cold in the winter then why not stay in the warm weather?
- It is freezing cold in the upper Midwest during the winter. Whooping cranes simply cannot find any food, even if they can endure the cold. During the summer, the upper Midwest has longer daylight hours and slightly cooler temperatures. than their wintering grounds in Florida. The longer hours allow them and their young more time to gather food. Reproduction is very taxing on the female body, even if it is just laying eggs. The young need the extra time and nutrition to grow quickly into adult sized birds. Small birds are more vulnerable to predators.

- Q:What is the theme of the poem A man to the universe by Stephen Crane?
- In the poem “A Man said to the Universe” by Stephen Crane three distinct images appear as the reader relates man and universe as they fit into their cosmic role. The simplicity of the five line poem envelopes man’s perception of his place among the universe, the universe’s perception of its role in the order of life, and the relationship of both man and universe in regards to the enormity of the cosmos. Collectively, these three components create a profound thought on creation. By Folrani Adewale
- Q:How often should the crane be inspected regularly?
- Lifting machines are inspected regularly every two years, and explosion-proof lifting machines shall be inspected regularly every year. Must have the corresponding inspection qualification inspection.
- Q:What is the safe distance of a tower crane to the surrounding buildings?
- The latest specification is that the tower crane is 4M from the proposed building.According to the safety regulations of tower craneRegulation 10.3: the tower crane tail and the surrounding building and its surrounding construction facilities between not less than 0.6m.Article 10.5 stipulates: between the two tower cranes of minimum distance should be erected to ensure that at least 2m in the distance between the tower crane boom end and another tower crane tower; the most part of the high tower crane (hook up to the highest or lowest part of the balance weight) should not be confused with the vertical distance of tower crane at in between the highest position of the components is less than 2m.The latest specification is that the tower crane is 4M from the proposed building.The distance from the tower to the building shall be considered:1, the slewing radius of the tower itself.2. The distance between the double shelf of building and tower crane.3, double shelf and tower crane safe distance.4, according to the specific type of tower crane to determine the specific.
- Q:I already have 864 cranes and I wanna know what kind of wishes can I make? And are there consequences?Can I wish something like my mom won the lottery and we become rich? (Just an example!)And can you wish for death? (Just a question!)
- You can make whatever wishes you want. Just remember that the wishes you make reflects what kind of person you are. So maybe you should make wishes you can be proud of. Also remember, if wishes were horses beggars would ride If you for example would wish that you would have $10, your wish is most likely to be fulfilled if you manage to sell each origami crane for 1 cent... Generally wishes come true if you really work for them, Not by sitting, doing nothing and wishing.
- Q:What is a tower crane without a collector?
- The advantage of the collector is that the tower crane can be turned on one side without any limit, and how many circles can be turned. The tower crane is basically not equipped with collector, because collector generally needs to be located at the center of the tower's turning center, so it is inconvenient for operators to go up and down.
- Q:My relatives and their kids are coming the 28th for our Christmas does any body know where I can get a Brio Crane for a 3 year old? most web sites I checked say sold out. Just wondering.
- Hi okorder . Please visit it and it will satisfy your needs. Best regards, Soma
- Q:Would David have made a better babysitter than a crane driver?
- Well, apparently he was a crap crane driver...
- 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?
- How Do They Grow? Tower cranes arrive at the construction site on 10 to 12 tractor-trailer rigs. The crew uses a mobile crane to assemble the jib and the machinery section, and places these horizontal members on a 40-foot (12-m) mast that consists of two mast sections. The mobile crane then adds the counterweights. The mast rises from this firm foundation. The mast is a large, triangulated lattice structure, typically 10 feet (3.2 meters) square. The triangulated structure gives the mast the strength to remain upright. To rise to its maximum height, the crane grows itself one mast section at a time! The crew uses a top climber or climbing frame that fits between the slewing unit and the top of the mast. Here's the process: The crew hangs a weight on the jib to balance the counterweight. The crew detaches the slewing unit from the top of the mast. Large hydraulic rams in the top climber push the slewing unit up 20 feet (6 m). The crane operator uses the crane to lift another 20-foot mast section into the gap opened by the climbing frame. Once bolted in place, the crane is 20 feet taller! Once the building is finished and it is time for the crane to come down, the process is reversed -- the crane disassembles its own mast and then smaller cranes disassemble the rest.
