Product Description:

FZQ series anchorage luffing-jib tower crane is a sort of large crane applicable for thermal power, hydropower, nuclear power, petroleum, chemical industry, metallurgy, high-rise steel structure and other erection of large-scale construction projects, especially suitable for tower boiler lifting in power station and construction of tall buildings at narrow site.
To meet the requirements in different operating conditions, FZQ series tower crane has been successfully developed such as FZQ1380, FZQ1650, FZQ2200, FZQ2520. This series of products adopt advanced production technology and design concept featuring in high technology content and excellent performance, which keeps pace with international advanced level, and has gained tens of China national patent technology.
The pedestal of this series crane adopts box-type structure resulting in non-concrete foundation, which reduces the foundation treatment cost.
This series tower crane adopts advanced anchoring method and structure that the anchoring location can be flexibly adjusted to a wide application range.
The connection of tower section adopts “HALF” quick-type structure, which simplifies assemble and disassemble process. The standard section and anchoring section can be interchangeable owing to the same geometry dimension.
Boom system is manufactured of fine-grained ultra-high strength alloy steel pipe with significant reduction in weight; the mast is made of high-strength low-alloy steel pipe that provides the crane with compact structure and strong lifting capacity.

The hoisting mechanism adopts international renowned brand gearbox and Lebus drum, which guarantees its good performance; the electric control introduces full frequency conversion to realize fast, stable and non-impact operation.

The crane is equipped with complete safeguard devices to realize multi-protection for safe operation.

Q:how to make a origami crane with flapping wings?
there's a website called origami club that has pretty easy tutorials also tons on youtube.
Q:How can you tell the difference between a mosquito and a crane fly?
Crane flies are about an inch long, sometimes larger - just the body, not including the legs.
Q:What was the mekhane (crane) used for in Greek plays?
For actors playing the gods. The Greeks loved theatre, and just like today, there were cheap productions with little merit or wothiness for remembrance. In these cheaper plays, the creators would try to appeal to the people's religious convictions by having one of the gods (usually Zeus) descending from heaven to resolve the conflict and set things right. To present this in theatre form, the actor would be lowered down to stage on a crane in order to simulate the god descending from heaven. This became such a tired cliche in ancient Greece that the phrase Deus Ex Machina, which translates to God of the Machine, has come to mean An unexpected, artificial, or improbable character, device, or event introduced suddenly in a work of fiction or drama to resolve a situation or untangle a plot.
Q:Boston Legal: Denny Crane Question!?
LOVE him as Denny Crane. He makes me laugh every time!!
Q:Equipment safety of tower crane
Safe distance tower and transmission line is not up to the requirements of the tower frame door frame to design, erection principle to power erection, do not use metal materials, bamboo and other materials can be used. The distance between a bamboo pole and a power line shall not be less than 1m, and a certain degree of stability shall be taken to prevent the wind from blowing. The tower crane height and bottom bearing size ratio is large, and the center of gravity of the tower body, high torque, braking frequency, impact force, in order to increase its stability, we will analysis the main causes of the tilting of the tower crane has the following:Overloading. Different types of cranes usually adopts the lifting torque based control, when the amplitude exceeds the rated load weight increase or the corresponding weights, the overturning moment more than stable moment of it, it may cause the collapse of the tower crane.Two, inclined hanging. Slant weights will increase its overturning moment, the lifting point will produce horizontal force and vertical force on the crane, bottom supporting point will produce an additional overturning moment, and the stability coefficient is reduced, resulting in tower crane collapse.Three, the tower crane foundation is uneven, the ground endurance is insufficient, the perpendicularity error is too big, also can cause the tower crane to overturn the moment to increase, causes the tower crane stability to reduce. Therefore, we should proceed from these key factors to strictly check, check and check, and prevent major equipment personal safety accidents. State explicitly eliminated the model should resolutely prohibit the use of, in disrepair, tower crane in the identification of the repair, to limit the use of load, tower crane for the use of fixed number of years there is no uniform standards, opinions vary, different places have different provisions.
Q:When the tower crane is installed in the fertilizer tank,
There is no standard in the tower crane foundation and building foundation, there is no such provisions.In fact, you can do whatever you can. The only factor that can be said is the Design Institute, to see if they agree.Design Institute to consider this problem, generally disagree, you let the two based on the surface flat, because there is a stress concentration problems. It's like a pebble under your mattress. So, in general they will demand based on the surface in the construction of tower crane foundation floor, the middle 30-50cm gap with soil pad.Of course, no matter which of these two methods you have to use the back belt to enclose the tower crane foundation.
Q:How long would it take to make 1,000,000 paper cranes if making one takes 7 min & 11 sec?
13 years 8 months 2 hours 13 minutes 20 seconds
Q:The arm of a crane at a construction site is 17.0 m long, and it makes an angle of 13.5◦ with the horizantal.?
The easy answer is that the applied torque is the cross product of the radial arm and the force, or in this case T = 811*17*cos(13.5). The hard (it's actually not that hard) answer will depend on the design and material properties of the crane. Since the problem asks for max torque, I'd find the bending stress due to the moment found above (T = 811*17*cos(13.5)) where bending stress = Ty/I. Next, compare this to the yield stress of the crane's material and an appropriate failure criterion.
Q:how can we minimize energy losses of a crane to reduce the impact on the environment?
No hint as to what type or size of crane, so I assume it is a large overhead traveling bridge crane inside an industrial building: Consult the manufacturer for recommendations. Change its power source to something cleaner (from diesel to propane or electric). Properly lubricate and adjust all moving parts. Turn power off when idle. Schedule heavy usage during hours of low demand of electric utility power. Replace motor with a more efficient new one. Replace entire crane with a new efficient one. Replace the large capacity one with one or more smaller units.
Q:How do you hang origami cranes?
TAke a needle threaded with a long piece of black thread, and make a small knot at end of long thread. Push the needle thru the middle of the crane's back and pull the thread all the way thru the hole till the knot catches. pull the needle off the loose end of the thread and make another knot on that end. take a push pin or thumb tack and push the pin thru the knot, then push the pin or tack into the ceiling. FYI, tape never works - I have tried. The black thread lets them flutter a bit, and is invisible most of the time. p.s. ask your parents if you can hang stuff from the ceiling first. they may not want you to do that since it will leave holes in the ceiling when you take them down.
