- Q: (a)What is the power output of the crane. (ignoring losses)?(b)If it takes the cran2 2 minutes to raise the payload to its final height, how far above the ground is this?(c)If the cable were to break as the payload reaches its final height, how fast would it be traveling as it hit the ground?
- 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 v? = u? + 2as: v? = 0.7? + 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: What is the function of the balance valve in the hydraulic jacking system of tower crane?
- The function of the balance valve is to maintain the balance of the oil pressure, the hydraulic oil delivery flow is stable, so that the tower crane jacket and the upper part of the lift, disassembly, standard time, lift and smooth.
- Q: I've always wondered, how do they lift cranes? Bigger cranes? What do you think/know?
- they build it peice by peice.
- Q: What is the difference between a crane and a crane in a tower crane?
- There are the following differences between crane crane and Signal Engineer in tower crane:1, lifting signals refers to those who signal flags in the works.2, the engineer referred to the engineer who tied the rope in the works.
- Q: What is the minimum radius of a tower crane?
- Luffing jib crane luffing mechanism to control the lifting radius, which is lifting and landing boom.At the minimum radius, the boom is angled to the vertical.
- Q: My boyfriend's a little sick right now, and he's going to have a surgery over summer. I'm in the process of folding him 1000 cranes (like the Japanese legend), and in every crane I wrote a message. I have a list of all the messages so far. I'm not sure how to give it to him, though. 1000 cranes is a lot of cranes... and I don't want to make him carry a big heavy box or anything. I also want him to be able to read the messages... something I didn't think of much when I decided to write them on the paper I folded the cranes with...Anyway, I was thinking about a scrapbook or something. But that would be a really big scrapbook. And I'd have to probably write out all 1000 messages again in it... Plus, I'm not sure if I can find a scrapbook with enough pages.Any ideas?
- A clear Glass vase would be cool, the colors of the cranes would make it decorative, and he could reach in to read one whenever he needs a pick me up. It is especially a good idea for the hospital, since they sometimes frown on flowers for allergy reasons. I also love the idea of a mobile, but that would be huge and time consuming, also the messages would be hard to read. But perhaps you could take 20 and turn those into a mobile, tie them to a stick with sewing thread, and plant the stick in the jar or vase you use to display the others.
- Q: What are the safety devices for tower cranes?
- (3) the lifting height limiter, lifting height limiter is used to restrict access to the hook jib head or trolley before, or is dropped to the lowest point (ground or below ground Ruoganmi) before the lifting mechanism of automatic power-off and stop working, to avoid lifting hook over hoisting device touch the boom and the bad.(4) the amplitude limiting device is used to limit the boom does not exceed the limit position in the pitch. An alarm is sounded when the lifting pitch reaches a certain limit, and the power is automatically cut off when the limit position is reached.(5) stroke limiter of car stroke limiter: a trolley type jib head and root, to cut off the circuit car traction mechanism, prevent car offside. Cart travel limiter: used to prevent the crane from derailing.
- Q: What company makes a good engine crane I can order online?
- I would suggest going to Harbor Freight or Oreilley's auto parts... they both should have them at at very reasonable price...if you order online it wouldnt be cost effective due to the shipping and handling added on to the price.
- Q: What are the differences between the tower crane and the lift?
- they are nothing alike
- 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.
