QTZ50(5010A) tower crane is hoisting and conveying machinery which is designed by fully utilizing the group technology, the combinational design technology and the finite element analysis technology and taking the tower crane microcomputer design platform as a tool and has excellent performance.

The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the effective amplitude of 50m and the maximum lifting moment of 500kN•m. The tower crane has the lifting height of 30m and the adhesion lifting height of 120m (2 magnification) during independent use.
All the speed indexes of the crane meet or surpass national standards.
The crane has the total installed capacity of 25.5kW, features advanced parameters, excellent and reliable properties, attractive appearance, high quality, simple and practical structures, advanced safety devices, convenient maintenance, safe usage and reasonable prices, and is ideal construction machinery for many medium-small construction enterprises.

The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

Q:Firstly I know there is a very good club near me which does 5 lessons a week, just to let you know.Firstly could you please tell me how much of white crane is actually fun and how much percentage is kicks and how much punches.I'm a very althletic boy age 15 and I don't know much about this style. Is it fairly exciting and what I might enjoy?Thanks for you help.
There are two types of White Crane one is Tibetan which is called HOP GAR or Bak hok it has both high and low kicks with long arm movements Fujian white crane has lower kicks and shorter arm/hand movements...At your age both will be fine
Q:I was wondering if anyone knows what period this book is set in? I know that it's set in the slums of New York and the story was published in 1893. But what time period does the story actually take place?
hah ha i'm in your class too :) This project sucks... and I still haven't done it! I have to tonight..
Q:Yeah, I think I know what cranes are used for. But in the context of building an apartment and so on, what is the role derricks there. And why is called cranes and derricks - What is the correlation between them.
Cranes are used for lifting heavy equipment. Derricks are used to drill for oil. They are two different things.
Q:Because they look a lot alike. Such as if you reinforced the design a little bit will it work?
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:I read this book recently and i got emotional over it. It relates so much to my life and i think maybe i know what my dad was thinking before he died. I was just wondering what was your reaction after reading this short story?
Sniff Sniff. 'tears rolling down my cheaks.
Q:Im looking for more information on Overhead Cranes!?
Advantages of Overhead Crane for Professionals When large materials have to be handled in the building, construction and mining industries, there are several types of equipment that would be used. One of such equipment is the overhead crane, and because of its size, it is conspicuously seen at construction or mining sites. Not only does it have a domineering figure but it is also a very versatile equipment for moving heavy materials from one point to the other. This equipment occurs in many forms and the various forms it has, makes it adaptable to many environments. There are other types of equipment that are available for lifting, but a crane is the preferred choice of many people. I got most of this information from www.hoistandwinch .uk There are several reasons people in the construction and mining industries would choose a crane over other equipment that are used for lifting. With overhead cranes, there would be absolutely no need to clear aisles before materials can be moved. Forklifts or fork trucks could have their paths blocked and a lot of time and energy would have to be diverted to clear an aisle. Obstructions that could even make you suspend important projects are irrelevant to overhead cranes because they would easily make it around them without any form of difficulty. It is therefore possible to arrange your plant floor the way you would want it to be for your business, without thinking about obstructions to the lifting and movements of materials with cranes to do all the task for you.
Q:i have a 100 ton american crawler crane. how do i calculate the psf, for this equipment.
Not sure what you are asking exactly... Are you saying that you have a crane with a capacity of 100 tons and you want to know the pressure on the soil where the crane is positioned? In this case, you take the capacity (in pounds) plus the weight of the crane (in pounds) then divide their sum by the area of the tracks on the crane (in square feet). This will result in pounds per square foot or psf as you wrote above. These are example estimates, they may not be anywhere near the correct answer, this is simply how to do the calculation. Assumed Capacity 100 ton = 200,000 lbs. Assumed Weight 105 ton = 210,000 lbs. Assumed Area of Track = 200 square feet Note: 1 U.S. ton = 2,000 pounds = 2,000 lbs. 410,000 lbs / 200 square feet = 2,050 psf There's a start, now you just need to find out how much it actually weighs and how long and wide the tracks are to get the area of the track on the ground. I hope that answers the question you were asking.
Q:I have to read this book for an AP class next year. I did read the book and i don't understand how i can discuss the setting and its possible relationship to the theme. I looked stuff up on the internet and I've asked other people who have read the book and they're just as confused as I am. I need help!
I can't tell you what to write or what you see as the theme but one of the themes in the book is man versus nature. Maybe you could discuss the setting as part of nature and what Crane seems to be saying about it. One thing that might help is a poem Crane wrote which explains how he sees things. Maybe you already know it. It's titled A man said to the universe A man said to the universe, Sir, I exist! However, replied the universe the fact has not created in me a sense of obligation. An indifferent universe. Not unlike how Thomas Hardy saw things.
Q:i was wondering
it would be better if you tried it. :P Ive never heard the story but this is actually wishing magick. so I would vote true on it, but i think there are better wishing methods that won't require that much time and won't kill trees. Blessings, Shadow
Q:Can someone tell me the difference betweem safe working load and capacity of a crane?If possible, please provide reference along with tour answer.thanks for the help!!!
What sort of crane? If it is an industrial crane in a factory, the maximum rating for the crane is always lower than the true maximum to allow for a safety cushion. If the crane states it cane lift say 1 ton, it can safely lift 2000lbs. It will lift up to 2300 lbs if needed though.
