Q:Military Action movie with bunch of cranes at the end?: Cranes like construction equipment or Cranes like the birds?

Q:What are the safety devices for the horizontal arm self lifting tower cranes?: (3) the amplitude limiting device shall be equipped with a minimum amplitude limiter and a device for preventing the boom of the boom from rebounding after the luffing of the jib. The trolley must be equipped with a trolley switch and a terminal buffer. (4) rail clamping device and walking limit device; track type tower crane must be equipped with rail clamping device. A walking limit device shall be installed at the same time. (5) a crane with wind point at the root of the boom with a height of more than 50m shall be equipped with an anemometer at the top.

Q:River? Please give me links. I have seen some videos on youtube about the plane getting lifted out, but none of the crane which is what I was wanting to see.: The best link I can find is this first one, the second may create more jobs tho...

Q:What should i do to solve tower crane collapse?: tower okorder / to see if whether your trouble is one of those tower crane troubles ?may be you can solve your question under its help.

Q:We would like some ideas from folks who have the cranes coming to their bird feeders. What foods are they attracted to?: Sand Hill Cranes are omnivores which means that they feed on a wide variety of food. Their diet will change depending on the time of year and the habitat. Part of their diet would be rodents, snails, frogs and other small animals. They also will eat the roots of aquatic plants and grains in farm fields. This is where you may be able to draw the cranes to your yard. Spread the bird seed on the ground. Even small piles of seed may help. These birds like to forage through grassy areas and can do some digging with their beaks leaving the ground lumpy, so be sure you want them in your yard.

Q:When the tower crane foundation is found, what should be discontinued?: The settlement, inclination and cracking of tower crane foundation can affect the stability of tower crane and should be stopped

Q:Two cranes are lifting identical steel beams at the time.One crane is putting out twice as much power as the other assuming friction is neglible, what can you conclude is happening to explain this difference?: Mechanical advantage. One boom may be at a lower angle than that of the other causing more force to be required to lift.

Q:I have preliminary data: up to 2 tons of weight; work range of 40 meters; lifting torque 800KNm; lifting height 45m.. I encountered problems in the design, and some of its specific reference, I would like to ask here, for example, how much is the weight of its whole machine, how much is the balance weight, the balance of the radius of gyration? Super boom weight? (it's better to have the approximate weight of each component). And when I design this tower crane, is it necessary to use planetary gear for the gear reducer?Thanks to your advice, Liu is here to thank you: You're welcomeDesign units are different.Our factory is Langfang Design Institute drawings. May refer to the following.Arms 55 meters long.

Q:If anyone can find me a decent video of a Fujian White Crane Kung Fu simple hand block then I will be very grateful! I know sort of how to do it but I would like to get it spot on.Thanks: To get it spot on as you say, it would be best to get it from your instructor. Videos are sometimes good and sometimes bad. In any case they are a bad way to learn something. They simply can't correct things. And that is assuming that the video shows them correctly in the first place. Learn from a competent instructor.

Q:I'm talking about one of the ones where the cabin and the worker is high up in the air. You cant exactly remove a part of the bottom of the cranes structure because it would fall on top of you but you cant remove the cabin because its so high up and what can get up that high to remove it except another crane BUT how did that get built ?Thank you.: A tower crane is usually assembled by a telescopic crane of smaller lifting capacity but greater height and in the case of tower cranes that have risen while constructing very tall skyscrapers, a smaller crane (or derrick) will sometimes be lifted to the roof of the completed tower to dismantle the tower crane afterwards. A self-assembling tower crane lifts itself off the ground using jacks, allowing the next section of the tower to be inserted at ground level.
