Main Features of Tower Crane
Our tower crane is self-erecting and wall-attached tower crane, in addition to it's advanced parameters, reliable performance, well-looking appearance, and excellent quality.
It has characteristica such as long boom, largeworking coverage, hydraulic rising, and tandem mounted tower body.
It's design idea shows advantages including simple structure and good applicability, convenient maintainability, and lower price at the same time to emphasize meeting the requirement from construction units at different levels.
It's lifting height is obviously increased thanks to its self-erecting and wall attached function.

FAQ about Tower Crane
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 about our tower crane warranty?
A: Usually there is one-year quality warranty including main electronic parts (not including consumable parts). There are consumable spare parts together with whole machine and normally they are enough for one year.
Q: What is 3 main mechanism of the tower crane ?
A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.
- Q: Equipment safety of tower crane
- The boom of a tower crane is divided into two types: horizontal and compressed arms. When the movable arm is horizontal, the carrier car runs along the horizontal arm with variable amplitude and amplitude, and the movable arm is longer, but the boom has a larger deadweight. The arm for the strut type when the tractor boom luffing mechanism pitch amplitude, amplitude motion than horizontal smooth, but its relatively small weight.The weight of a tower crane varies with its amplitude. The product of the weight and the amplitude is called the load torque, which is the main technical parameter of the crane. Through the rotary mechanism and slewing tower crane, lifting height, rotation and walking the inertial mass, so it needs to have good control performance, especially the lifting mechanism can fast, slow, heavy and light load installation fretting. In addition to the general use of resistance speed regulation, but also often use eddy current brake, FM, pole change, SCR and mechanical and electrical joint speed regulation. When the crane in the layout to drawing, especially in real estate development area, residential buildings, such as tower crane, but also to consider the safety distance of adjacent tower crane, two in horizontal and vertical direction to ensure the safe distance of not less than 2m, the adjacent tower crane tower crane and interference can not occur. Try to ensure that the tower crane in the wind is too large to be free of rotation. The safe distance between the rear arm of tower crane and adjacent buildings shall be no less than 50cm. The safe distance between tower crane and power line meets the requirement.
- Q: I loved Dr. Crane and his sexy glasses and eyes. Plus, I just love Cillian Murphy, haha. Is his character back in the Dark Knight, I heard he was...but I was wondering if anybody could confirm it?
- Dr Crane Scarecrow
- Q: Plus why the symbiot instead of bringing the dark side of the carrier brought the gay and jerk side?
- 1) Something happened to the crane - it doesn't matter what - it was an excuse to bring out spiderman, What happened isn't important. It was a kind of malfunction anyway - NOTHING to do with any villians 2) Gay and jerk side? He wan't being gay, but because he was a jerk in the first place that is why he didn't really know how to dress up properly and being up himself means he doesn't recognise it - which by the way, was well scripted into the movie. It was a bit of a comic relief. The symbiot brought out the darker side of him but that doesn't mean it KNOWs to make him behave appropriately.
- Q: What is the difference between a tower crane QTZ31.5 and a QTZ40?
- Lifting moment, arm length, elevation is not the same ah! Specifically, the maximum lifting weight of QTZ315 is 3 tons, the length of the arm is from 38-42 meters, the elevation is 27-28 meters; the maximum QTZ40 is 4 tons; the length of the arm is 42-48 meters; the elevation is 29-32 meters.
- Q: Do cranes play major role in Japanese culture? How so? Do cranes live in Japan?
- yea, i think there was this japanese girl, and she was exposed to radiation from that bomb in Hiroshima (i think) so she ended up being diagnosed with cancer and yea, she believed that if she folded enough paper cranes (coz cranes apparently live to very old, so if she could fold 1000 of them, she would live longer), she would get better... so she kept folding them until she died.. TT___TT such a sad story... So now the crane represents peace! yea.. thats all i remember... ^^
- Q: Under what circumstances does a tower crane require third party testing?
- New installation, demolition, close, major transformation, the use of site work committee, the use of factories to the Technical Supervision Bureau
- Q: I'm making 1000 origami paper cranes. I started 2 days ago and have 135 done so far but I was wondering what do to with it after. I don't want to just make them and have them sit in my room forever.
- Well if you don't want to keep them you can look up organizations that wish to use them for a project. There are a lot for Japan, one that was organized recently for the tsunami was accepting cranes for a fundraiser (every crane sent in earned a certain amount of money with the finished collection being placed in an art museum). I know some hospitals accept cranes for the children's ward, that is what my class did in elementary school we made 1000 and the hospital used them as decorations for the Christmas tree. Then there are individual projects that people start online with which they are accepting cranes to fulfill the one thousand mark for people they know who are sick etc. (relates to the story behind the 1000 paper cranes practice). As a side note if you contact the organization you find a lot of the time the shipping is prepaid you just have to drop them off at the post office. Hope this helps.
- Q: what is the meaning of the color red in the book The Red Badge of Courage by stephen crane?
- Wound while in battle is symbol of bravery, hence the blood stain as proof or evidence.
- Q: Do they come all the way down?
- the operator turns the engine off and puts the crane put it into safety mode so it doesnt hurt near by workers and open the door of the crane but before he does anything els he first turns on the alarm on so no one steals the 5 ton crane when the operators in the bathroom taking a crap/piss doing whatever...
