Q:How many meters of cranes should be in accordance with the anemometer?

Tower crane type test items, technical requirements and test methods provides that: Boom root hinge point height of greater than 50m tower crane, should be equipped with anemometer. When the wind speed is greater than the working limit wind speed, the alarm can be issued to stop the operation. The anemometer shall be installed at the top of the tower without the wind.In fact, this is also the requirements of the type test rules for tower cranes and the safety technical specifications for crane overload protection devices.The answer is recommended dogmatism, mainly because the standard setters do not understand the actual situation of the construction, and not the outdoor crane need, need only part of crawler crane and tower crane installation, as the case may be other.Welcome to the emperor student - lifting expert Sina blog, my blog is committed to the dissemination of hoisting safety and professional knowledge.

Q:Since a crane has to extend outriggers while performing lifting operation , is it ok to allow a crane to transfer materials by carrying without extending outriggers and lifting and carrying load to different location especially in construction industry for safety reasons?

It would work but there's the danger of the load swinging damaging the crane or other vehicles or losing it's centre of gravity toppling etc. when it's moving. For most lifts the outriggers are required to stabilise the crane itself - not the load. You're dead right - the on-site safety protocols that are in place these days demand that everything is done absolutely the right way. If anything goes wrong there's be hell to pay for anyone involved even if they've done their best to get things right.

Q:anyone know of any Crane Kung fu teachers in MN twin cities area?

Sorry, I don't. have you checked the Yellow Pages for that area?

Q:explain thoroughly please

Sure. Let's say that a crane needs to hoist a load of 10 tons, and that because it needs to reach over some obstacles, needs to lift at a horizontal distance of 50 feet away. That creates a torque about the base of the crane of 500 ton·ft. By positioning a counterweight on the opposite side of the tower, the magnitude of the moment can be mitigated. For instance, let's say a counterweight of 10 tons is positioned at 25 ft on the other side of the tower. The moment produced by the counterweight is 250 ton·ft, so the net moment at the base is 250 ton·ft. Furthermore, when the 10 ton load is positioned and release, there is still a 250 ton·ft moment at the base of the tower; it has simply switched direction (say from rotating the crane to the right, to rotating it to the left).

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.
