Q: I had this dream where I was watching a flock of Sandhill Cranes on a road. Cars were swerving to avoid them, but one sporty red car lost control and smashed into a brick wall, killing some of the birds. The rest of the cranes started freaking out, flapping their wings and coming towards me. They were so frightened that they started to defecate too. Soon though, there was so much bird poop that it became like a river ready to engulf me. It was like a glowing white too (really weird, I know).Then, their legs turned into human legs, and the cranes turned into tall, beautiful humans with wings - angels, I think. These beings radiated power and filled me with terror as they approached. They must have been 8 feet tall and they towered over me. One red-headed angel looked at me when he passed, and I was so terrified that I woke up.Any ideas about what this could mean? It's one of the most powerful dreams I've ever had.
First of all, to see a crane in your dream, represents happiness, maternal love, and your gestures of good will. You look out for those who are near and dear to you. Alternatively, a crane signifies tact, immortality or vigilance. Furthermore, dreaming of an angel can mean two things. Purity, protection, comfort and consolation. Pay careful attention to the message that the angels are trying to convey. These messages serve as a guide toward greater fulfillment and happiness. Alternatively, it signifies an unusual disturbance in your soul. Angels may appear in your dream as a result of your wicked and mean-hearted activities.
Q: have you noticed that there has been an exceptionaly high volume of cranes falling over in the U.S.A. this year? 2 cranes went down this week, one in Texas killing a man. seems like there has alot of this lately, what the hell is going on with the cranes? ever night i turn on the news its like a deadly crane accident took place today . thanks.
My brother is a crane driver, and its scary when you hear about these accidents. Last week a man was killed in a quarry when the crane he was in touched an electric wire
Q: what type of hydraulic oil does a 2007 liebherr LTM 1160 5.1 crane take?
You're telling me you've been entrusted the control of a crane capable of reaching 565 feet up an you don't know what hydraulic oil it takes?? Jesus Christ mighty... First off, it's in the owners manual, second off it's probably on the resivoir cap.... If you couldn't figure that out you shouldn't be allowed near the damn thing...
Q: For starters im nine and i dont know how to win the claw game ive tried like a million times (exagerating) and i never get it! Can someone be kind and tell me plz! I have seen prizes that i really want and most of them are animals! I am an animal lover and ive seen dolphins or puppy stuffed animals and i never can get them! :( plz help any one if u can i would really appreciate it!
Is this a video or online game?
Q: my class is supposed to start reading poems/short stories by Stephen Crane.why should i look forward to his work?
Well, you know he lived in the late 1800s, so you probably have an idea of what his poetry will sound like. Then you read some of it, and the effect is sort of like walking into what you think is going to be a prissy hair salon and being whacked over the head with a bunch of bananas wielded by a glow-in-the-dark green monkey from Jupiter. Crane's stuff is that weird. And I mean that in a good way.
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)
The Tibetan style is based on the Tibetan White Ape and is a separate style having no relation to the Fujian style. The Fujian style from Yong Chun Village (aka Wing Chun Village)is the Original White Crane. Shouting, Feeding, Shaking, Leaping and Ancestral Crane styles which are practiced in Taiwan are based on Yong Chun White Crane. Edit: Shaolin white crane is Fujian White Crane. It is not a Shaolin Style but it has roots in the Shaolin 18 Lohan Style. emei white crane? There is no Crane Style in the Omei branch of CMA.
Q: I have a Manfrotto/Bogen 055XB tripod that says it supports up to about 15lbs. The crane I'm looking into getting is the Glidecam Camcrane 200 which says it has a payload of up to 30lbs. depending on the height. What would happen if I were to use this crane with my tripod?
Please let me know where you will be so I can capture the video of your camera crashing to the ground. Because you overloaded the tripod, there will be no warranty coverage for anything. Yes, they can tell. ++++++++++++ I realized I had not provided an alternative... the crane specs also specify Camcrane 200 mounts on the 3/8 standard bolt found on the majority of medium and heavy duty tripods an
Q: Emergency treatment of interrupted electricity during lifting of tower crane
When the power supply fails, you should first remove the things that are stuck in the gear!
Q: What is the wall radius of a qtz50 tower crane?
The working radius is usually 50 meters. There are also 48, 49 meters. For example, 4810, 4910, and 5010, belong to 50 tons of tower cranes.Qtz50 resolves to:Q: crane;T: Tower type;Z: Jack up;50: lifting torque of 50 tons meters.
Q: i was wondering
There is a legend that if a person makes 1000 cranes then they get one wish. Cranes are a sign of longevity in Japan and children often make cranes and bring them to a famous shrine in Japan. Not sure if its true or not. I'm testing it out now actually. Just 900 something more cranes to go.
