Q: How would the environment, habitat, or ecosystem be affected if whooping cranes were extinct?: Whooping cranes ARE a part of the food chain..every animal on the planet is....Nata has NO clue what they are talking about. And I HAVE seen a whooping crane before..in the wild while working in Florida. Only 6 existed on the refuge I was working on and I was lucky enough to see 4 of them. It is something I will never forget! If we lost this bird, the animals it feeds on may increase in numbers causing plagues, and other birds that may live and feed in similar habitats may become too plentiful as well since they would have no competition from the cranes. Those birds could in turn wipe out other species. There are also many changes that might take place that we could not even guess at...until it actually happened. This is often the case as we still do not have a great understanding of how one species affects another. But all species DO affect one another, think of each species as a link in a chain, or a strand in a spider web. If you start snipping strands in a web, or damaging or breaking links, what do you think will happen. They will weaken and collapse and eventually fall apart.

Q: What is the scope of the installation and disassembly of self lifting tower cranes and the applicable range of the cost and the off-site transportation cost?: The installation and disassembly of the existing self rated tower crane, the first cost and the off-site transportation cost quota are divided by the lifting moment 1000kNm and 2000kNm of the jack up tower crane.

Q: How do they erect those giant cranes used for constructing tall buildings?: They hire the Egyptians that are on lay off from building pyramids to build the cranes.

Q: I have a crane fly in my room. I know they don't bite but do they bother people or tend to completely avoid them? I can't find it and I'm going to sleep soon.: ANY type of bug bothers me. Especially the creepy crawlies. *shudders*. I wouldn't go to sleep if i knew i had a type of bug in my room. I guess you'll have to deal with them. Sorry. Good luck finding it.

Q: What does a track type tower crane look like? In that case, use?: The rail type multi characteristic tower crane consists of track, door frame, main arm, auxiliary arm, hook and so on. Its features are: A, crane through the door frame (2), supported on a track (1); B, the door frame (2) is provided with a rotary bearing (3); C (3) is arranged on the rotary supporting all kinds of machinery and equipment (4), and balance weight (8); D, the main arm (5) the jib (6) through the bearing cable (7) is installed on the rotary support (3); E, the main arm (5) side arm (6) and Russo (7) can have a variety of length combination; F, a main arm, jib all tube truss structure; G, hook pulley h, equipped with a variety of rate; the torque limiter (10) and amplitude detection device (11); I, operating room in slewing bearing (3); J, self moving use winch is luffing winch main arm, mounted on a rotary support (3).Track type multi characteristic tower crane. The utility model is especially suitable for power construction and hoisting operation. The slewing support on the track type door frame is provided with a main and an auxiliary arm frame, and various variants can be formed through different combinations. Its maximum torque of 3360 tons meters, the maximum lifting capacity of 140 tons, the maximum working range of 60 meters, the maximum rise of 120 meters. The utility model can be carried in the lifting, and the work is smooth and safe. The main and auxiliary arms are all truss structures, light in weight. The electronic torque limiter and other safety devices are adopted, and the 130 meter high machine can be installed by itself. This machine can also be used in petroleum, chemical, metallurgical and other large projects.

Q: What kinds of concrete are there in construction crane? Mainly for the construction of this area ~ ~ ~!There is no lifting machinery issued by the state what ~ ~ which detailed description of the construction machinery lifting what?: National and trade standards for construction and lifting machineryStandard number, building lifting machinery, national and trade standard nameGB 6974.9-1986 lifting machines -- Nomenclature: Tower CranesGB 6974.1-1986 lifting machinery terminology - lifting machinery typeGB 6974.2-1986 lifting machinery terms - main parametersGB 6974.3-1986 lifting machines - Terminology - General conceptsGB 6974.4-1986 lifting machinery terms - bodies and other componentsGB - 6974.5-1986 lifting machines - Terminology - safety indicating devicesGB 6974.6-1986 lifting machines -- Terminology -- mobile cranesGB 6974.7-1986 lifting machines -- Terminology -- Railway CranesCranes; cranes; GB; 6974.8-1986; terminology; floating cranesGB 6974.9-1986 lifting machines -- Nomenclature: Tower CranesGB 6974.10-1986 lifting machinery terms - portal cranesCranes; cranes; cranes; GB; 6974.11-1986; terminologyCranes; cranes; GB; 6974.12-1986; terminology; bridge cranesGB 6974.13-1986 lifting machines -- Terminology -- gantry cranesGB 6974.14-1986 lifting machines -- Terminology -- cable cranes

Q: i need to know:how long is the stock (extended and non-extended)how wide is the stockand how thick is the stockthanks.: I believe it is pretty difficult to tell and searching the schematics of the crane stock will be as well. Best way is to check out your local gun range and the folks there that shoot guns with crane stocks installed. Also, though I am not too sure about this one, check if the crane stock is compatible for mil-spec buffer tubes and commercial spec buffer tubes. Otherwise, I am very much inaccurate in any of this response.

Q: I am 15 years old and into urban exploration. The only thing I haven t done yet is climb a crane. I don t want a big lecture on the dangers because I am fully aware of how dangerous it is and am also fully confident in my abilities. I am also ready to take full responsibility if I were caught. Although I know its Illegal, I don t know how Illegal it is and I would like to know the following...1. Will Crane Climbing get me charged with criminal trespassing?2. Will I get time in Juvenile?3. Is it possible that I could accidentally activate/deactivate something that would endanger the workers?4. What would happen if a worker got ahold of me?And again I feel like I need to mention that I don t want a Bull **** lecture on it not being safe. :): Trespassing is illegal. How illegal? LOL... illegal is illegal. I'm not going to look up the possible fines for you.

Q: Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?: Use trigonometry, it's a triangle of forces.
