Q:Why is there as much evidence of Icabod Crane, as there is of god??
Ichabod Crane is real! He has big feet, just like in the cartoon! And you can't tell me otherwise!

Q:But theres always someone who gets a prize everytime. Its so unfair!lol
I'm usually one of those people who gets the prize - or whoever is with me at the moment LOL. Who needs an excuse to watch Spongebob? I watch it even when my kids aren't around. Its one of those shows you wish you could hate, but its just too funny!
Q:I need it for my English class, not to cheat, but because my literature book only has an excerpt, in which I didn't even know Yukiko's name. And my teacher insists on finding it out for ourselves and I just want to know what the story is about and what the scandal repeatedly implied in the excerpt is.
It's been a while, but I believe the story is about a young girl who gets cancer, and sets about making 1,000 paper cranes for good luck, but she never made to completion. Just google to find info, or see if you can download the book.
Q:dimentions of crane rail, crane beam.
What kind of crane? There are thousands of types.
Q:What windproof devices should be set up for crane work?
Safety protection device and function of crane1. overload limiterIt is a safety guard for cranes to prevent overload, also called a weight limiter. The safety function of the utility model is that when the crane load exceeds the rated value, the lifting action is stopped, so as to avoid overloading. Overload limiters are widely used in bridge type cranes and elevators. Some boom type cranes (such as tower cranes and gantry cranes) use the overload limiter and the torque limiter together. Overload limiter has mechanical, electronic and many types.(1): mechanical drive ram through a lever and a spring cam, etc., when overloaded, hit the switch control rod and the lifting action phase, cut off the power source of hoisting mechanism, control the lifting mechanism to suspend operations.(2) electronic: composed of a sensor, an operational amplifier, to control the actuator and load indicator, display, control and alarm and other security functions in a body. When the crane is loaded, the sensor on the load bearing component is deformed, and the load weight is converted into an electric signal, and the value of the load is indicated by operation amplification. When the load exceeds the rated load, the power source of the lifting mechanism is cut off so that the lifting action of the lifting mechanism can not be realized.
Q:feminists always point to sexism. but Ive found 3 women here - who say they have experienced no sexism, and were pleasantly surprised by how excepting their largely male co-workers have been -
Have you failed at something? A physical for a job? Have you failed a civil engineering exam? Why take the blame yourself. Scream sexism By the way most crane operators don't pee out of the crane. Most urinate into a bag of gelatin that can be disposed of later. There is a special cuff for females to use with the bag
Q:I love Bates Motel but I'm just scratching my head like WTF? I'm not being racist but Marion Crane wasn't black in Psycho but okay I'll take it. I guess they may have to find a black actress for Lily Crane. My goodness I don't mean to sound racist but maybe they should've got Maitland McConnell to play Marion. I don't know maybe it's me.What's is your opinion on this?
I'm alright with it, the Marion Crane character is actually someone Rihanna should play really well, she's a rogue(Marion), and in a modern version, you need to have someone who can do that credibly. Rihanna's more expressive, more aggressive personality will be better than Maitland, Maitland is very much the slasher-bait so far in her movies, Marion Crane has more potential than that.
Q:Tower crane body standard section connection bolt screw upward or downward, why?.
Usually it is worn from top to bottom, so that the nut is loose and the bolt will not fall directly
Q:How come you never see cranes being transported from one site to another?
They are, the big pieces are moved at times of very low traffic. The huge cranes that build skyscrapers are made up of many small pieces, and the main tower is actually part of the building, not the crane.
