Design Features of Bridge Girder Launching Gantry Truss Girder for Bridge Construction
1. Reliable performance
a) Apply the latest separate pinned structure of triangular space truss to main girder, so as to improve the stiffness and strength of whole crane.
b) Main girder is made of Q345 high strength steel, and melt into the latest design to ensure the main girder can work under high strength mode safely.
c) Modern crane brand launching crane is pioneering in continuous one time operation during bridge launching progress in China. It is of the most complete function launching crane for single machine domestically.
d) Compared with similar products from other supplier, Moderncrane brand launching crane have its unique design concept to the most difficult hole-span during bridge erection, in the way of laying side beam. So, it is safer to operate under high difficult and risk condition.
e) Powerful front, middle beam and three transom crane connect together to ensure transverse stability during bridge erection fully.
f) There is separate stroke switch control to each traveling mechanism, so as to decrease mutual collision between each traveling mechanism.
g) Overload resistance system: there is high performance weight limiter on two sets of trolleys, so if the lifting girder is overloading, the weight limiter will stop it at once.
h) There are normally three legs from other supplier. But we have four legs, including one front leg, one middle leg, one rear leg and one temporary leg.
i) Apply inner shrink leg to one time erect side beam in position and have more safety.
2. More powerful corrosion resistance
a) Strictly execute standard painting process to ensure blasting and painting quality.
b) Apply H steel enclosed section for main girder chord. Web chord is made by customized square tube to realize enclosed welding, which can avoid inner rust.
3. Higher working efficiency
a) There is traveling rail together with main girder, trolley and longitudinal crane. So, it is no need to lay traveling rail more. In this way, a lot of auxiliary materials are saved and production time is also saved.
b) Modern crane launching crane has higher working efficiency, with 6~8 pieces girder erection every day, based on enough concrete plate supplying, skilled operator and good condition at site.
4. More flexibility
a) It is symmetrically designed. Two way girder erections can be realized without split and slewing at original place.
b) Use one meter of hydraulic jack for front leg and rear leg. This design improves working efficiency, safety and flexibility largely.
c) Erect skew bridge by inclined way. Apply rotary face flange to connect each mechanism and structure, to erect 0~45°skew bridge. Side beam can be positioned one time for over 320m curve radius bridge.
5. Easier assembly and disassembly
a) Each structure is connected by pins and bolts to facilitate assembly.
b) Normally one set of launching crane can be assembled within 7days.
- Q:Kindly help me out, I prefer sanskrit. but elese english would goes
- Try okorder /... and look at the other posts. Good Luck
- Q:Im trying to start a buisness building wind turbines.
- It will be easier for you to buy it. Carbon fibers are made several ways. One is making polyacrylonitrile fibers, then coking them; the nitrogen runs off with the hydrogens. You can also make fibers from pitch and coke them. Coking the fibers is NOT simple or easy. Also, carbon fibers are a real pain because they short electric equipment
- Q:Thus increased unemployment. Would these changes in unemployment be considered increases in full employment underemployment or recessions? If you said the former, which sector of unemployment (frictional, structural, cyclical) increased?
- This would be an increase in structural unemployment. It cannot be recessionary, because it says nothing about a decrease in output below full-employment level. It is not frictional, which relates only to the time delay between when someone is unemployed and when they get a job that is available and that they are qualified for. It would be structural, as the structure of the economy has changed. The people have skills for jobs that are no longer available, but not for the jobs that replaced them: jobs relating to the production and distribution of the new farm machinery. In the sense that there are fewer of these new jobs than there were of the old jobs, then the natural rate of employment would decrease by the difference in available jobs.
- Q:Do you enjoy operating heavy machinery?
- I got to drive a forklift the other day.. i dont think thats heavy machinery (i couldn't pick it up so i guess its heavy) But that was heapsa fun because of the turning circle forklifts have. When i was younger my dad would let me operate the big backo's (digger thingies) that was fun 2, but scary.
- Q:High oil costs makes the consumers cry,....low oil prices makes the refineries cry too...who suffers most?
- even the cars that use alternate fuel use oil how else are the parts gonna get lubricated? so it wont be that bad for them
- Q:I personally believe it is in little ways. 1.) Advertisements are continually cheapening human interaction. Example: the man who is talking about finding his queen and we think he is talking about a woman but no he is talking about a sofa. 2.) Face to face interaction has become less and less important in society. We are all on our phones, watching TV or on our computers sending text messages or on facebook. 3.) Everywhere you look people are not looking at the person they are talking to, they are too busy with gadgets. I mean who here has been annoyed becuase the person they were talking to was texting?So basically my question is, Do you think technology is good or bad for humans?
- Yes actually I believe it is also. I went from calling my mother like 6 times a day to sending her and my little sister IM's on Yahoo Messenger, and hitting up their myspace's. We do it more and more since she moved from where I am in Massachusetts to Georgia. Also, I Google everything. A Dictionary, Thesaurus, Phone Book, even Bible I can look up all the information online.
- Q:Why is the paint of the construction machinery yellow?
- Construction machinery yellow is the majority of enterprises to choose the color of the product, Caterpillar in many yellow paint products stand out and apply for a patent. Not sure whether other companies imitate Caterpillar or because yellow has a warning role, I personally tend to believe that other manufacturers imitate Carter. Why do you want to imitate Caterpillar? Because Caterpillar construction machinery industry undisputed boss.
