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: why does the power company use helicopters to service the repair lines instead of trucks with tall cranes?
- High-tension lines operate at hundreds of thousands, or millions, of volts. At this potential, electricity can jump through several feet of air to reach a path to ground. This pretty much rules out using trucks, because it would be prohibitively expensive or impossible to build a crane out of entirely non-conductive materials. A helicopter is electrically isolated from the ground, so it's less difficult to drop a technician off and let him hang from the line itself while working. (It is still necessary for the technician to use a wand to bring the helicopter to the line's potential before starting work, because of the capacitance of the helicopter's body.) They could of course use a truck to service the lines if the power was disconnected, but the cost of shutting down service to an entire region of the country exceeds the operating cost of a helicopter.
- Q: how is a tall crane constructed? how can they put the crane on top of its tall body frame?
- They first construct the top of crane on the ground with help from other mobile cranes. This includes the long horizontal part with the operator's cab, and the concrete counterweight. this is then placed on a climber, with which the crane kind of builds and climbs itself to the necessary height. Every vertical section of the crane is placed in the climber. When the piece is in place, the climber climbs to the top of piece from where the next vertical piece is placed and so on. You can see how a crane is constructed in the website I've cited below:
- Q: Probably my favorite of the jumping kicks I practice, and I'm curious what experiences you guys have had with it. I've caught people of guard with it after using a crescent or roundhouse kick in kickboxing, and I've done it with a knee to the chest then the kick to the head in Muay Thai. I've also practiced the ten foot kick (using the initial foot up to propel yourself forward instead of up) and crossed the ring to the opponent before they could move. What are your thoughts? What kind of variations do you practice? Ever had any good/bad results from it?
- Every technique has its purpose. If you have favorites, you are limiting yourself by putting more emphasis on one thing over the other.
- Q: how many different types of cranes and winches are there?
- A bit more information might help. In England there are Winches and then there are winches. As for Cranes are we talking about birds.........actually there are only a few type of each.......but there can be quite a few variations of the basic types. let's say 6 types of cranes and 4 or 5 winches.
- Q: Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
- Standard number: GB/T 5031-2008Standard Name: Tower CraneStandard status: currentAlternatives: instead of GB/T 17806-1999; GB/T 17807-1999; GB/T 5031-1994; GB/T 9462-1999This standard specifies the nomenclature, classification and identification, technical requirements, test methods, inspection rules, information identification, packaging, transportation and storage, installation and climbing, and inspection of tower cranes.
- Q: the highest ranking American serviceman, at least in the so called prison camp
- no, he was brutally murdered
- Q: this wind speed refers to that height of wind speed?
- This is not on the project department climbed to tower crane to measure wind speed, regardless of height, is listening to the local meteorological station forecast, more than five winds, should stop working.
- Q: A family of cranes are at my house they are attacking my ducks and im scared they will kill them
- where do you live
- Q: how do construction crews put up a crane?
- They assemble it on a concrete foundation using a mobile crane. To grow taller, the top unit of the tower crane has a jacking mechanism that lets it raise itself up and insert another tower section.
- Q: A heavy concrete panel is being lifted into position in a building by means of a crane (see figure below). The tension of 1.78 x 10^4 N in the supporting cable produces a torque with respect to point O. (Let L = 46.3 m.)
- The crane contributes a torque of 495,979.8 Newton-meters. 1.78e+4 * 46.3 * cos(53.0) = 495,979.8 ...but this is not the total (net) torque. There is also a torque due to the weight of the concrete slab - torque we are ignoring since we do not know the weight of the slab.
