Founded in the year of 1996, Yongmao is one of the key suppliers specialized in manufacturing construction machinery and engineering equipment.

We currently offer a variety of tower cranes which are broadly classified under the Topless STT series, the ST series, the Luffing STL series and the Derrick QD series, as well as crawler cranes and modified vehicles.

Yongmao tower cranes have not only been working for various domestic projects like hydroelectric power plants, nuclear power plants, shipyard, wharf, bridge, aerospace etc. but also acting in numerous construction projects all over the world.

Yongmao appreciates the reliance and confidence given by its valuable users all over the world and feels very proud of its ability and capability to contribute value added services to its users both at home and abroad.

Q: How would the environment, habitat, or ecosystem be affected if whooping cranes were extinct?
the whopoping crane is not a part of the food chain. Nothing would happen. 100 birds is not a pencil point in the data. We spend millions on this bird and it's lose would NOT be noticed by anyone. I'll bet not one person on this form has even seen one, can tell us what is food chain function is. A link to a post or wikpedia won't cut it either, I want the exact species that is in the chain both up and down and what the exact effect would be. Since no one can give a specific chapter and versus on the specifics and talk about genaerizations, IMHO, I'm correct. NOW If the question was about the loss of all Raptors in the world, there would be an upset. The Whooping crane in it's self is so small it's impact of lose is zero. I call BS on the poster that says she saw them in FL. NOT ONE SINGLE WEB site lists FL as it's home range. You could at least have gone to Wiki and gotten your facts right and answered my AP question, but you instead tried a red herring act to promote your bias. PS I've been to the AP and know all about them (clue tell us what I meant here and prove you are a player on this subject)
Q: Equipment safety of tower crane
The boom of a tower crane is divided into two types: horizontal and compressed arms. When the movable arm is horizontal, the carrier car runs along the horizontal arm with variable amplitude and amplitude, and the movable arm is longer, but the boom has a larger deadweight. The arm for the strut type when the tractor boom luffing mechanism pitch amplitude, amplitude motion than horizontal smooth, but its relatively small weight.The weight of a tower crane varies with its amplitude. The product of the weight and the amplitude is called the load torque, which is the main technical parameter of the crane. Through the rotary mechanism and slewing tower crane, lifting height, rotation and walking the inertial mass, so it needs to have good control performance, especially the lifting mechanism can fast, slow, heavy and light load installation fretting. In addition to the general use of resistance speed regulation, but also often use eddy current brake, FM, pole change, SCR and mechanical and electrical joint speed regulation. When the crane in the layout to drawing, especially in real estate development area, residential buildings, such as tower crane, but also to consider the safety distance of adjacent tower crane, two in horizontal and vertical direction to ensure the safe distance of not less than 2m, the adjacent tower crane tower crane and interference can not occur. Try to ensure that the tower crane in the wind is too large to be free of rotation. The safe distance between the rear arm of tower crane and adjacent buildings shall be no less than 50cm. The safe distance between tower crane and power line meets the requirement.
Q: Tower crane four limit, two insurance, two insurance what is that?
Four limit: torque, ultra high, variable amplitude, walking limit device. Two insurance: hook insurance and reel safety device.
Q: What is the difference between a crane and a crane in a tower crane?
Informal: hoisting signal worker: refers to the signal flag!Cable man: rope!
Q: I know that there's Tibetan and Fujian but what are all the styles and which is the best one to learn ( in your opinion)
Fujian White Crane is short stances, short hands and close range fighting system. The other white crane is said to be from Tibet but developed in Guang Dong, southern part of China, and Hong Kong. This style emphases on deep stances, long arm movements attacks. Both of them are great styles. Steak and Lobster. which one is the best to eat? Your pick!
Q: Please help me. I have to write and essay about it and i cant find it on the web!! no anywhere i can get it from ONLINE?!?!?! any particular search engines?

Q: a 10 crane is moving across a frictionless surface at 4 m/s. if you wish to bring the crate to a stop, how much work would it need to do to dissipate all the kinetic energy?Physic
If an object with mass 10kg is moving at x m/s it's Kinetic energy is ?mv? =?×10 kgm?/s? = 5x? Joules Example: 10kg @ 4m/s Ke = ? (10kg)× (4m/s)? = 80 Joules
Q: Two Cranes have been sitting on nest for about 50 days. Will these 2 eggs hatch. They will not leave. It is their 3 Clutch. The first one resulted in a baby colt, but it got hit by car. The second never hatched.
What species of crane? Sandhill cranes have an incubation time of around 30 days, do you know the exact day of egg laying? Are you sure they haven't hatched and they are sitting on chicks? If you are getting close enough to the nest to see eggs or chicks, you might be too close and could be interfering with their natural behavior, unless they are captive or you are using a blind. You mentioned their chick being hit by a car, so if they are nesting that close to people, they may be nervous and are flushed from the nest too often to keep the eggs the right temperature. It's hard to say without more information. Edit: Extra cold weather can damage the eggs. It does seem like they've lost this clutch-50 days is long past when they should have hatched. They may be trying to incubate them anyway, I haven't worked directly with sandhills, but other birds that I've conducted nest monitoring studies on have sometimes sat on nests a while past when the eggs should have hatched. Hopefully this is actually their fourth clutch and you missed the removal of the third clutch. Good luck!
Q: How do cranes use geometry?
If your referring to cranes in construction cranes, then it might form a right triangle with the ground implying the use of trigonometry which is a part of geometry.
Q: Two cranes are lifting identical steel beams at the time.One crane is putting out twice as much power as the other assuming friction is neglible, what can you conclude is happening to explain this difference?
One of the cranes has less mechanical advantage then the other. It's a pulley problem.
