Main Features of Tower Crane

 

1) This kind of crane adopts standard section hydraulic lifting and connecting.The max. height can reach 180m with wall tie ins.

 

2) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.


3)The range-change structure drives the trolley moving on the horizontal crang jib, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.

 

4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..

 

5)The cranehas scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.

Q:A crane is lifting a 500kg payload straight up at a constant speed of 0.7ms-1.?
a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v² = u² + 2as: v² = 0.7² + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
Q:can anyone give me some info on how to become a crane operator?
I agree. There are schools (USA) that teach this kind of thing. You attend, receive a diploma attesting to your success then you can approach prospective employers that hire people with these skills. I wish you the best. :)
Q:what is the load combination with crane load and seismic load according to asce?
Uh, depends on if you're using ASD or LRFD load cases out of ASCE 7-05. I also think IBC 2006 sometimes changes the fine print and also offers their own load cases for ASD and LRFD. A starting point (LRFD case 5 ASCE 7-05) might be 1.2D+1.0E+ L, and for ASD - case 6 - D + 0.75(0.7E) + 0.75L.
Q:Does anyone know where I can order Sugar Crane to grow?
Crane? anyway,, if your store has those little pieces you can buy to eat? or if you know someone with canes,, you strip off the hard outer covering,, this has the seed buds,, plant these in 3 inches of soil and wait,, cane is slow growing!! if you google sugar cane growing or go to wikipedia you will find plenty of info google buy sugar cane seeds you will find sites to order!!
Q:Electromagnetic crane?
www.okorder.com/.. Add a childs toy crane and you have a Electromagnetic crane Ta Da.......
Q:What does a crane symbolise?
The cranes' beauty and their spectacular mating dances have made them highly symbolic birds in many cultures with records dating back to ancient times. Crane mythology is widely spread and can be found in areas such as the Aegean, South Arabia, China, Korea, Japan and in the Native American cultures of North America. In northern Hokkaidō, the women of the Ainu people, whose culture is more Siberian than Japanese, performed a crane dance that was captured in 1908 in a photograph by Arnold Genthe. In Korea, a crane dance has been performed in the courtyard of the Tongdosa Temple since the Silla Dynasty (646 CE). In Mecca, in pre-Islamic South Arabia, the goddesses Allat, Uzza, and Manah, who were believed to be daughters of and intercessors with Allah, were called the three exalted cranes (gharaniq, an obscure word on which 'crane' is the usual gloss). See The Satanic Verses for the best-known story regarding these three goddesses. The Greek for crane is Γερανος (Geranos), which gives us the Cranesbill, or hardy geranium. The crane was a bird of omen. In the tale of Ibycus and the cranes, a thief attacked Ibycus (a poet of the 6th century BCE) and left him for dead. Ibycus called to a flock of passing cranes, who followed the murderer to a theater and hovered over him until, stricken with guilt, he confessed to the crime. Pliny the Elder wrote that cranes would appoint one of their number to stand guard while they slept. The sentry would hold a stone in its claw, so that if it fell asleep it would drop the stone and waken.
Q:I was looking at how to make your own camera crane... I was wounder can you make one from a microphone stand?
It might - but the center of gravity and the tripod might not be able to hold the weight of the jib, camera, counter-weights... and personally, I think it would be a pretty expensive mistake to watch my $2,000 camcorder fall and brake because the camera crane collapsed under the weight. A mic tripod is designed to handle about a pound of weight. A consumer camcorder, the jib and counterweights (and maybe a mic or whatever else you throw on there) can be between 5 pounds and 50 pounds. That's why companies like Kessler make what they make. And that's why the companies that makes lesser camera cranes (Cobra, CameraCranes, and others) never use a mic tripod. They use a heavy duty camera tripod or other LARGE, STRONG, item - not a mic stand.
Q:CAB BE CRANE BOOM EXTENDED AT 0 DEEGREE BOOM ANGLE?
I suppose Tadano is the manufacturer and they make several models most of which are safe at zero degrees with two sections extended. The weight of the extended cable and hook need to be added to the weight being lifted or lowered, so the allowable weight could be zero for a very long cable. Some safety factor is present, so you may choose to push your luck. A cable that breaks suddenly can whip around in a dangerous manner. If you bend the boom replacement will be very costly. If the boom was bent in a previous lift, it is much weaker than an unbent boom and the extending feature may jam. Neil
Q:what year did ichabod crane die?
In the story no years are given, and in fact the end is left open ended. It seems to say that Ichabod Crane was still alive at the end: humiliated he had slipped out of town in the night. Though it does say the townsfolk spread rumors and stories told that he was carried off by the headless horseman. The fictional character of Ichabod Crane was based on the personality of a real person, Jesse Merwin, who died in 1852. (though thirty-two years after the story was published and not in any spooky way) The name, Ichabod Crane, also came from a real person, Colonel Ichabod Crane, who fought in the War of 1812 and died in 1857.
Q:airsoft gun crane stock to full stock switcharoo?
Ok, I can help. The first step is to take the crane stock off. To do so, extend the stock fully. Then, take the tab you use to extend it, and instead of pushing up to extend it, pull it down and slide the stock off. It make take some force. Be careful of any wires and that you don't break them! Next: take the buffer tube out. Take a long phillips head screw driver and stick it down the shaft. Remove the screw. The whole tube should come out. Don't lose the screw! Next: Install your stock. Next: Screw the screw back in to secure the stock. Done! Make sure the wires are still ok and that they are not pinched!
