Q:Recently, it seems that any time my front door is open for any period of time, crane flies start migrating inside. I would like to find a way to keep them out when the door is open. Are crane flies attracted to electric bug zappers?
It is much easier to eliminate the reason crane flies occur around your house. They occur in moist areas with decaying vegetation. Unless you live in a swamp you should let the soils around your house dry out. You can also spray the area around your door with an insecticide to keep them from gathering there.
Q:What are the special operators of tower cranes?
The tower has special operations personnel of heavy machinery refers to the construction site in the tower crane division signal cable, installation and disassembly, the driver, and the demolition work of gondola installation, may cause serious harm to themselves, others and the surrounding facilities operations personnel.
Q:Any difference?
The crane part can be identical, but the vehicle part differs: in the former case it's a road-going (even multi-axle) truck, in the latter case it's an off-road vehicle with oversize all-terrain tires and appropriate traction and transmission capabilities. In either case, the vehicle must be stabilized on adjustable hydraulic struts before hoisting.
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:I know it sounds like a silly question but I just wanted to know what kind of crane he is because I've never seen a crane with black feathers.
Red-crowned Crane is a large crane and is the second rarest crane in the world. In East Asia, it is known as a symbol of luck and fidelity
Q:What are the three different types of Cranes?
Whooping crane Crane your neck. Bob Crane from Hogan's Heroes.
Q:Grade 4 build a working crane Help!?
I would use about a 2 foot piece of broomstick pinned through a hole in one end. Maybe 2 to 3 inches away, a larger clearance hole with a 1/4-20 nut glued under. Use a lo-o-ong 1/4-20 bolt as a driver. (1/4-20 is 1/4 inch diameter with 20 threads per inch.) I leave the mounts and string up to you as to encourage your participation and creativity.
Q:the red badge of courage, a novel about the civil war, the verb wrote is A) transitiveB) intransitive
Transitive - because it has an object The Red Badge of Courage. . Generally, if you can put the word something after a verb, it is transitive. Stephen Crane wrote something .
Q:if the crane starts out at ground level and the skyscraper is being built next to it, how does the crane get moved to the top of the building once the skyscraper has been built to the level of the top of the crane? (eg: the crane can reach a height of 30 stories but the building being const. is 100 stories)
it takes two cranes
Q:How to calculate life span of steel structure? for example, crane?
To calculate it, you would need to know all of it's dimensions, the average loads that will be applied to it daily, the natural conditions which the structure is exposed to, the carbon content of the steel as well as the manner in which the raw steel was produced AND the manner in which the crane was assembled. Even with this data it would still be an extremely generalized calculation.
