Q:My relatives and their kids are coming the 28th for our Christmas does any body know where I can get a Brio Crane for a 3 year old? most web sites I checked say sold out. Just wondering.: Hi okorder . Please visit it and it will satisfy your needs. Best regards, Soma

Q:What are the safety devices in a tower crane?: (1) lift height limit position limiterFor cranes with variable boom angles, the lifting motion must be stopped immediately when the top of the lifting device rises to the 8OOmm at the lower end of the boom.For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately.(2) lifting moment limiter and maximum lift limiter;When the lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped.If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value.When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.(6) lightning protection and anti electromagnetic wave induction device;For the crane whose hinge height is over 50m, the lightning arrester shall be installed according to the actual situation and the electromagnetic interference shall be taken.(7) tower crane shall install limit torque coupling in order to prevent slewing overload.

Q:if i make 1000 origami cranes what does that mean?doesnt it mean that you get a wish or something? cause i heard a story about it a long time ago but i dont remember. im pretty sure that if you make 1000 cranes you get one wish: Yeah, but you'll probably wish that you hadn't spent so much time making that many paper cranes.

Q:Operation points of tower crane (tower crane)?: Slewing bearing: tower crane is one of the most critical components, mainly to bear overturning moment and vertical load. After the failure, the demolition and replacement is extremely difficult, loss of large, so you have to check carefully to do maintenance, each 200H must be a senior grease lubrication from the rotary bearing surface, until now exudation. Slewing bearing adopts high strength bolt connection, if the pretension is not enough, or long-term operation, do not check, not fastening, will cause loose. If the individual bolts loose, will cause the remaining bolts overload, the consequences will be disastrous. The luffing mechanism only moves horizontally, the load is light and the line speed is not high, so it should be easy to master and operate. However, the amplitude involves the change of the lifting torque, and if there is no stopping in time, there will be the possibility of over torque. Therefore, the main requirement of variable amplitude operation is stationary parking and accurate positioning. The tower crane is of great height and the hanger is hung longer, so it is easy to swing the hanger when it is running. This is an objective phenomenon. What is called stabilization hook operation is how to make the swinging hook stop quickly, or how to make the hook move with the movement of the crane as soon as possible, and minimize the operation of the swing. The operation of stabilization hook is the skill that the driver should master.

Q:(Fujian) white crane: U might want to try google. Good luck

Q:It's got to be the most famous of all designs in the art.: NOOOOO! I can't! It frustrates me so much. (Got an origami kit for my b-day) But at least I can make a butterfly... and I used to know how to make a penguin when I was like 7

Q:Please help me. I have to write and essay about it and i cant find it on the web!! no anywhere i can get it from ONLINE?!?!?! any particular search engines?: nicely, on the initiating i grew to become into watching this snippet of Zeigeist while they have been conversing approximately Jesus and faith oftentimes (that's incredibly lots my quest at that element) after which I stumbled upon the the remainder of it... Which grew to become into like, whoa... you'll be able to desire to comprehend... i'm from Malaysia (that's in South East Asia) and that i observed the twin Towers coming down at nighttime on CNN. on the initiating i presumed it grew to become right into a action picture, until eventually my mom advised me this is not. It sparked an obsession with me... I watched CNN day and nighttime almost for the full month, into Iraq and all, searching for updates into the situation. that's why each and every thing clicked into place when I watched Zeitgeist. additionally, being in a Muslim united states has given me an decision view on the full rely being that they teach the brutality of the yank military in Iraq. Yeah, so it makes extremely some experience. i don't comprehend why some human beings discover it so stressful to have self belief. while? Oh... early this year. ;-) i know i'm overdue, yet for an prolonged time I had different issues occupying my ideas (migrating from one united states to a diverse and such). happy to work out extremely some truthers around! in case you may desire to hook up with me, i could better than gladly oblige. =)

Q:ok so i have to us my phone so just give me instructions no links no youtube videos cause my phone cant support them and my phone may not be able to load some of the links: You are asking for a lot but I have seen you request this a number of times, so I will do it...a sucker born. 1. Valley fold the paper in half so it makes a triangle. With the long side held away from you, valley fold the triangle in half again. 2. Lift the top triangle and valley fold it so that its top point meets its bottom point. Unfold the crease you have just made. Put your fingers inside the top triangle, open it up, and flatten it so it forms a square. Turn the paper over and fold and flatten the remaining triangle in the same way. 3. Make sure that the open ends of the paper are pointing down. Valley fold the top layer of both sides in to meet the centre crease. You will now have a kite shape. 4. Valley fold the top point of the kite down and crease well. Unfold the crease you have just made. 5. Open the sides of the kite by unfolding the flaps you made in Step 3. Lift the top layer of the kite's bottom point up so the paper bends at the crease you made in Step 4. Push the outside edges of the paper in to meet the centre line. Then flatten the figure so that you have a long diamond shape. 6. Turn the figure over and fold a kite shape on the remaining side as in Step 3. Repeat Steps 4 and 5 on this side. You will now have a two-sided long diamond. The bottom half of the diamond is split in two. 7. Valley fold the top layer of both bottom edges in to meet in the middle. Turn the figure over and repeat on the other side. 8. To make the crane's neck and tail, valley fold each half of the bottom section out to the sides. Crease well. 9. Unfold the right crease you just made and make an inside reverse fold. Repeat this step on the left side. 10.To form the head, fold down the end of the neck. Unfold this crease and inside reverse fold the head. 11.Hold one of the crane's wings in each hand. Blow hard into the opening on the underside of the figure and gently separate your hands. You crane will puff up and be ready to hang.

Q:The car weights approx 900 kg.Thank you xx: Gravity acts downwards, force = mass x acceleration. Crane acts upwards at same force. As the crane starts to lift the car there is upwards acceleration that causes more force to be generated for a moment.

Q:Is the pink paper crane used to represent Lulu?: i really dont know what i can say to that so ill just shut up
