- Q: Ever since a few weeks ago, these retarded giant mosquitos thingys keep on flying into my house from somewhere and they always come into my office and bother me, so im wondering what month they come and what month they leave?
- Crane flies tend to live in wooded areas and open fields, but they can live nearly anywhere, including snowy northern climates and desert lands. In order for their eggs to hatch and larvae to grow into adults, they require either water or damp, decaying material in which to lay their eggs, depending on the species. Crane fly larvae and pupae can be found in damp sod or compost piles, or under the decomposing leaves on the banks of rivers, streams, ponds or lakes. Crane fly larvae and pupae feed on decomposing material, grass and the roots of many plants. This makes them a beneficial insect, as they assist in the cycle of decomposition. Once they emerge in late winter or early spring as adults, after maturing over the winter, their primary purpose is to mate and lay eggs.

- Q: More specifically, do Sandhill Cranes eat squirrels?

- Q: I have these sand cranes that always come up to our house and we feed them bread they never were aggressive but now one certain one is getting more aggressive. We have a screened porch and they come up to it and there putting holes in it to get our attention and there making like a noise thats not that normal when they see us. The one certain one is getting more aggressive towards the other birds poking on the them and chasing them. There is a group of four and they always stay together. the other three arent as aggressive as the one. He is bigger then the rest of them and is almost like the boss you could mostly tell he was before. He always let the other eat first while he watched around and when we gave them bread he used to be the last one up there now hes the first one there and literally runs to us when he sees us.
- Sounds like the aggressive is the Dominate male of the herd. I know you like to feed them but that's what started the problem. He is being Dom so he can get more food and be the first to eat. Once they figure out you're not going to feed them they will go back to behaving normal. These are cool to look at, even though they can get loud sometimes. Have you ever seen tourist feed sea-gulls at the beach. Locals don't do it. Sea Gulls will get as aggresive as the Sand Cranes and actually dive bomb people. Imagine what a Sand Crane can do being what 10 times the size
- Q: What is the Tower crane Roadb track laying criteria?????????
- The okorder ) track in the vertical and horizontal direction is not more than 1 / 1000. (we Should use the standard instrument, two tracks, and keep in10m range ,Measuring not less than 3 periods, respectively,taking the average).
- Q: Since now everyone will know what's coming when you get in the crane kick position, and the element of surprise is gone, has the crane kick become an extinct move? Do martial arts experts not like the Karate Kid for ruining the crane kick in the way magicians don't like other magicians who reveal their secrets?
- No. Anyone who poses for any technique like in the movie is going to get hit. Movies are for fun, not for learning to preform a martial art.LOL The Crane kick should come fast and un telegraphed not like in the movie. It is very similar to the Taekwando jump front kick.
- Q: A crew built this huge crane to build an office building next to my house.... There is a huge flag hanging from the top of it.... Why does the construction company do this???
- Wind becomes an issue when lifting large loads with a crane that has a long boom. On some large cranes you may see an anemometer near the end of the crane's boom. The crane operator will usually not make certain heavy lifts if the wind speed is too high. If the crane does not have an anemometer, they may be using a flag to tell them the direction of the wind and to give them a rough estimate of wind's speed.
- Q: total motor kw-100kw,crane class-m6,the crane should be operated on ups as the conventional electric supply is off , back up time require-30 min.
- To account for the inefficiencies, and startup currents, you should have a 200 kW (200 kVA) inverter with peak power of 800 kW. The batteries would have to store and deliver about 150 kW. But lead acid batteries would need to be of a higher capacity to guarantee that power level for 1/2 hour, which calculates to 75 kW-hour. I'd say 100 kW-hour capacity. A large 12 volt battery can store about 100 amp-hours which translates to 1 kW-hour, so you would need 100 of this size batteries connected in series/parallel. I made a lot of guesses, you should get better numbers for the motors, the inverters and batteries for a more accurate calculation. An inverter of the size needed will not be a 12 volt unit, but probably 48 or 96 volts DC. so you need to configure your batteries in series parallel to get that voltage. Altogether, the 100 large batteries make this not a practical solution. There are lots of large cranes in the world, what do they use for backup? And why do you need backup. With no power, the clutches would keep the crane and loads fixed in position, my guess.
