FAQ of Tower Crane
Q: What kinds of tower crane are available now?
A: Four main categories: normal tower crane with cat head, internal climbing tower crane, top less tower crane and luffing 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: Your tower crane is similar to Potain or Liebherr type?
A: We could develop any type of tower crane as per clients’ requirements if the clear information is provided. Originally, our tower crane design is based on Liebherr; but now, we not only introduced Potain design; but also developed special tower crane according to the market needs such as TC5013A with panel mast section. In addition, we also produce some models same as Potain original model, such as F0/23B, H3/36B and etc.
- 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: The role of slewing limiter in tower cranes is limited
- The function of the rotary limiter is to restrict the large arm to stop at a certain setting. Protect from turning to dangerous range so as to avoid collision and other dangerous accidents!The function of the amplitude limiter is to restrict the car to come out or return somewhere to stop and protect the car from or within certain dangerous range.The hook safety device is to prevent the wire rope from falling out of the big hook, so as to avoid falling and other dangerous events!
- Q: What's the difference between QTZ63 and qtz630, isn't it the same kind of tower crane?
- It's the same kind of tower crane, but it's only a unit of rated lifting torque. The former unit is 63 tons. M, the latter is 630 kn m. According to the latest national standard "tower crane", GB/T5031-2008 and QTZ63 are written correctly.
- Q: It's got to be the most famous of all designs in the art.
- Yes okorder
- Q: I have to create a crane to support a dead load for my Engineering Technology class. It can be made out of only 1/8 inch balsa wood and wood glue, and is going to be graded by the ration of weight held to structure weight.Could anybody give me some suggestions as to how to go about designing this thing? I already know most of the basics, but if anybody could give me some specific tips, they would be greatly appreciated.Thanks!
- Is this for a nuclear power station? If 2500 Te and 60m really are the specified loads and span then it is likely that it will be used very seldom. In theory you can design for any load to be lifted but maintenance on a crane system that is used once a year (10 years?) is a real problem. The main items to consider are: Availability of winches and bogies which then dictates running beam and rail sizes. For the spanning beam several alternative sizes needed to be designed and then costed. It will be not just weight but transport costs that determine the most efficient sizes The overall height of the crane will then determine the required roof height assuming that the crane is under cover. For comparison the Harland and Wolf cranes in Belfast called Samson and Goliath can lift 840 Tonnes each. Overall design needs to consider speed of travel, acceleration and deceleration rates and a host of other things.
- Q: How do I get on the cranes on the Highrise map in MW2?
- NO okorder /
- Q: How do cranes get from one construction site to another without hitting streetlights, wires, car, buildings?
- They dodge by the stuff as they fly along. Duhhh
- Q: More than meters of tower cranes must be equipped with red barrier lights at the top
- To see the land of tower crane or floating crane... Basically, however, tower cranes over 30 meters above the tower shall be equipped with red light on the top of the tower and jib.
- Q: This has nothing to do with travel, I'm just curious. I hate it when the news doesn't follow up on stories they focused on earlier. Does anyone have a status update on that crane that was swaying in the wind during Sandy?
- My friend, that is a good question. According to the latest news conference from the Mayor, the crane's boom arm is secured to the structure. However, West 57th Street between Broadway and 7th Avenue is closed until farther noticed. In addition, the 57th Street-7th Avenue subway station on the N, R and Q Line is closed and trains are bypassing the station in both directions, according to the MTA. Good luck Native New Yorker
- Q: Four for crane, two for insurance, two for insurance. What does that mean?
- Refers to the air switch and the electric leakage protector in the electric tray.
