QTZ4807    FAQ

Q: What kind of steel used for tower crane?

A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.


Q: What is the meaning of the tower crane’s code?

A: Take TC5013 for example, the first two letters “TC” means Tower Crane, “50” means jib length is 50 meter, and the last two letter “13” means the tip load is :1.3 ton.


Q: What is the function of the monitor?

A: Monitor, namely inspection system (like black box), which could store 10000 tower crane operation reports, and it is recommended to be installed in big cranes more than 16t.

Q:Is a tower crane a fixed type crane? Still can walk? Thank you
It can also be called a fixed crane. But there are many kinds of fixed cranes.
Q:What is the power of a tower crane? Five
TC7525-16D switchboard power 80KWTC5610-4 switchboard power 34KW.TC6015A-10E switchboard power 71.5KWThe other two types have not been touched and will not be answered. I'm sorry
Q:What measures should be taken to make tower cranes stable?
Increase deadweight and weight.Crane wire rope is phosphate coated steel wire, galvanized steel wire, stainless steel wire rope or coated steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment optimization of hot galvanized wire rope - double coating phosphating, phosphating coating to improve the wear resistance and corrosion resistance of steel wire that is not easy to wear and corrosion resistance is to improve the working life of the plain steel wire rope will be completely eliminated.
Q:What does the lifting mechanism mean in a tower crane?
Magnification, in simple terms, refers to several ropes through the hookIf it is one in and out of two wire rope, that is two magnificationSimilarly, two into two out is four magnification
Q:What are the requirements for jack up and plus section of jack up tower crane?
When lifting, a standard section is hoisted on the imported beam or introduced platform. Then open the pins or bolts connecting the standard section with the slewing support. Start the oil pump, so that the cage in the standard section of the outward sliding, until the release of a standard section position, and then imported beam or imported platform on the standard section into the connection. This completes a process.
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:How many tons of tower crane QTZ80A lifting?
Lifting torque = mass * radius of gyration (amplitude). That is to say, the bigger the weight is small.
Q:What is the scope of the installation and disassembly of self lifting tower cranes and the applicable range of the cost and the off-site transportation cost?
The installation and disassembly of the existing self rated tower crane, the first cost and the off-site transportation cost quota are divided by the lifting moment 1000kNm and 2000kNm of the jack up tower crane.
Q:How to improve the stability of tower crane
Phosphating coating of steel wire rope, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just add the last bonderizing process, steel wire, wear resistance and corrosion resistance is greatly improved, the use of the wire without direct phosphating cold twisted steel wire rope.
Q:What does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
