QTZ80(TC5513A) tower crane

QTZ50(4810B) tower crane is hoisting and conveying machinery which is designed by Shandong Fuyou Co., Ltd. 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 48m and the maximum lifting moment of 544kN•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 24.9kW, 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.

2. Lifting Technical Performance
2.1 Lifting Performance Table and Lifting Performance Curve
(1) 4-magnification Lifting Performance Table

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: How to calculate the pouring and maintenance of tower crane concrete in valuation?: Valuation, tower crane concrete foundation pouring and maintenance costs are included in the tower crane rental costs, not separately assessed.

Q: Please help me on this question, I can't seem to find it anywhere on the internet! :(: No animals depend on Siberian crane but they are a source of food to carnivores in the wild.They are usually secondary source because there are mroe source of food that carnivores could eat.SO if they are extinct,it would not be a problem...its only destroying natures beauty!

Q: Plus why the symbiot instead of bringing the dark side of the carrier brought the gay and jerk side?: what is with the gay?? Do you have an obsession with men or something?? Are you sure your not the one who is gay? Since when is sensitivity a sign of being gay?? who taught you that? You should really have a talk with yourself about your sexuallity.

Q: why do siberian crane migrate in india?: Would you spend a winter in Siberia if you could fly south?

Q: Tower crane four limit, two insurance, two insurance what is that?: Refers to the air switch and the electric leakage protector in the electric tray.

Q: It got me thinking.: I have not seen the movie, but I think I saw what you're talking about on a preview. I would think that the safeties involved in the control system for a crane would make it highly unlikely to happen. There is no absolute assurance, only probabilities or likelihoods. You just hope that you have enough failsafes in the system so if one part of the system fails, the others will take over, or shut the whole thing down properly.

Q: Tower crane demolition safety technical disclosure, how to write?: Baidu search:Tower crane removing and lowering joint safety technical disclosure.

Q: What role does the tower crane torque limiter play?: The torque limiter has two kinds of electronic type and mechanical type, electronic type: can show the torque, radius and load, near the tower crane permit torque, there will be a warning signal, although easy to use, the working conditions of cutting has been greatly affected, but not very reliable, easy to damage, the maintenance of trouble. Mechanical type: Although there is no display and can not alarm, but the work of the letter, the structure is simple, not easy to damage, suitable for construction site conditions.

Q: In Batman Begins, what was Dr. Crane/ Scarecrow (Cillian Murphy) after? What did he get in return with working with them and why did he work with them? He doesn't strike me as the kind to work with groups, he seems like a guy who rather work alone.: Only Crane did. Falcone was merely the top dog crime boss at the time. Ra#x27;s al Ghul is a self proclaimed savior of the world, a person who thinks he can cleanse the world of crime, but actually an extremist who just wants to watch civilizations reach their pinnacle then see them destroyed. Here#x27;s a quote from Batman Begins: Gotham#x27;s time has come. Like Constantinople or Rome before it the city has become a breeding ground for suffering and injustice. It is beyond saving and must be allowed to die. This is the most important function of the League of Shadows. It is one we#x27;ve performed for centuries. Gotham... must be destroyed. Get the idea? Crane helped create a fear toxin in Batman Begins but Batman foiled it. Bane came to Gotham to wreak havoc and become Gotham#x27;s Reckoning but Batman foiled him and Ra#x27;s daughter, Talia#x27;s plans. Both plans were to spread fear and both were foiled. One last thing about Ra#x27;s: He#x27;s the immortal Devil of the D.C. Universe.
