Product Description:

QTZ63C(TC5009A) tower crane is a fixed, self-erecting and wall-attached tower crane. In addition to its advanced parameters, reliable performance, well-looking appearance, and excellent quality, it has characteristics such as long boom, larger working coverage, hydraulic rising, and tandem mounted tower body. Its design idea shows advantages including simple structure and good applicability, convenient maintainability, and lower price at the same time to emphasize meeting the requirement from construction units at different levels. Its lifting height is obviously increased thanks to its self-erecting and wall attached function. It is applicable for construction of different industrial, commercial, office, and civil building lower than 160m, and thus becomes an ideal service-building machine at home.

Q:ichabod crane?
Maybe he drank a lot of absinthe and smoked a lot of opium!
Q:Flocks of cranes shout'. Is it right to use the word'shout' here?
If that's what it sounds like, sure.
Q:How do concrete blocks get to the top of cranes? I know why they're there but how do they get up there?
Construction cranes are erected on site. They are usually assembled on the ground with small cranes, then lift themselves up. The erection sequence is carefully figured, so minimal other equipment is needed. For conventional cranes that are permanent and thus only assembled once, portable cranes are used to erect them. Still, generally pretty much on the ground. Some have counterbalances that are permanently fixed, others have a rail type mechanism that moves in and out.
Q:how can i calculate size of battery and how can i design ups system to operate eot cranes which have 100 kw to?
To account for the inefficiencies, and startup currents, you should have a 200 kW (200 kVA) inverter with peak power of 800 kW. The batteries would have to store and deliver about 150 kW. But lead acid batteries would need to be of a higher capacity to guarantee that power level for 1/2 hour, which calculates to 75 kW-hour. I'd say 100 kW-hour capacity. A large 12 volt battery can store about 100 amp-hours which translates to 1 kW-hour, so you would need 100 of this size batteries connected in series/parallel. I made a lot of guesses, you should get better numbers for the motors, the inverters and batteries for a more accurate calculation. An inverter of the size needed will not be a 12 volt unit, but probably 48 or 96 volts DC. so you need to configure your batteries in series parallel to get that voltage. Altogether, the 100 large batteries make this not a practical solution. There are lots of large cranes in the world, what do they use for backup? And why do you need backup. With no power, the clutches would keep the crane and loads fixed in position, my guess.
Q:How are those really tall construction cranes assembled ???
I saw one erected once - it was fascinating. They started out with a big mobile crane - then they added piece by piece until they finished it.
Q:What is the work done on the beam by the crane? What is the work done by the force of gravity on the beam?
the work done on the beam by the crane = 1265 * 9.81 * 26 + 1265 * 9.81 * 0 = 322651 J answer work done by the force of gravity on the beam = 1265 * 9.81 * 26 + 1265 * 9.81 * 0 = 322651 J answer
Q:How do tower cranes stay balanced when they have very long booms and very heavy loads moved inward and out?
I think the counter weights are connected to a pully system that directly interacts with the boom and hook movement. This way it can put more or less pull on the weights according to the amount of weight or position of the weight on the crane.
Q:what is the common material using for crane boom?
Steel, like you said, do you want an exact specification? That will vary by whether it is a very long and slender tall crane or a shorter heavy duty for considerable loads. It may even vary depending on whether the manufacturer has as a goal an extra light weight unit using more expensive stronger steel or is willing to use thicker walls to use more ordinary steel. That is what engineers are for.
Q:Can Ichabod Crane defeat the Headless Undocumented Worker before he prunes someone's bushes into hedges?
It's people like you who are the reason the governor of our state had to declare a STATE OF EMERGENCY to get federal help to stop these people from coming here. You do not understand the problem because you ARE the problem.
Q:would someone who study both white crane kung-fu & ninjutsu be called a mixed martial artist?
Not by most MMAists. Strictly speaking, studying two martial arts is just cross training. To be MMA, the elements of the two would have to be blended together and trained in a realistic way (sparring), with equal attention being paid to the stand-up, clinch, and ground-fighting phases of combat.
