QTZ4808 FAQ
Q: What is the brand for the tower crane converter?
A: Normally, more than 10t series tower crane is equipped with converter. The selected converter includes SCHNEIDER, SIMENS, YASKAWA…it could be selected as per clients’ request.
Q: What is tower crane?
A: Tower crane is a modern form of balance crane that consist of the same basic parts. Fixed to the ground on a concrete foundation (and sometimes attached to the sides of structures as well), tower cranes often give the best combination of height and lifting capacity and are used in the construction site.
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 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 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: How to choose tower crane in engineering, such as arm length and lifting weight?
- 1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.
- Q: what are the number meanings for paper cranes?
- Hey Mary, Don't let the web site name fool you, it does discuss the deeper meaning behind paper cranes. Steeped in ancient myths and carrying resonant cultural meanings, the crane occupies a central role in the Asian imagination. Anyone who has witnessed cranes flying through the early morning mist over shimmering green rice paddies will readily understand how the mysterious beauty of the crane has captivated Asian life and art for centuries. Like the dragon, tiger, and phoenix, the crane ranks among the favorite motifs for Asian artwork because of its rich meaning and history. Read more at the web sites.
- Q: If I have one week, is that enough time?
- It all depends on how fast you can make one paper crane and how many hours you have available each day. If you made 15 an hour for 10 hours each day (150 cranes a day) for 7 days you would have 1050 cranes. You will probably find that you begin to go faster, the more cranes you make. However, after 2 or 3 days you will get sore hands and this will slow you down again. It's easier when you work as a team.
- Q: The rated lifting capacity of a tower crane refers to what is allowed and what is allowed to be divided by the crane
- The total quality of the crane rated liftingweightincludes the lifting load and the hook and rope a simplified example, such as the rated lifting weight of 100 tons, the quality of the hook and spreader for 5 tons, the actual quality of the goods can lift 95 tons.
- Q: What are the four major moving mechanisms of a tower crane?
- Tower crane refers to the fuselage for the tower frame, can walk along the track, a crane equipped with rotary arm. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system.
- 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.
- Q: Two Cranes have been sitting on nest for about 50 days. Will these 2 eggs hatch. They will not leave. It is their 3 Clutch. The first one resulted in a baby colt, but it got hit by car. The second never hatched.
- What species of crane? Sandhill cranes have an incubation time of around 30 days, do you know the exact day of egg laying? Are you sure they haven't hatched and they are sitting on chicks? If you are getting close enough to the nest to see eggs or chicks, you might be too close and could be interfering with their natural behavior, unless they are captive or you are using a blind. You mentioned their chick being hit by a car, so if they are nesting that close to people, they may be nervous and are flushed from the nest too often to keep the eggs the right temperature. It's hard to say without more information. Edit: Extra cold weather can damage the eggs. It does seem like they've lost this clutch-50 days is long past when they should have hatched. They may be trying to incubate them anyway, I haven't worked directly with sandhills, but other birds that I've conducted nest monitoring studies on have sometimes sat on nests a while past when the eggs should have hatched. Hopefully this is actually their fourth clutch and you missed the removal of the third clutch. Good luck!
- Q: my sister would like to know this for some strange and bizzar reasion
- It depends on how many people are making them. Depending on skill it takes about 2-5 minutes to make a crane. If you dedicate 5 hours a day that makes 7-50 days if one person is making them. Cranes are often made for memorial. It is a Japanese tradition, especially for Hiroshima. You make 1000 cranes as a memorial for the lost lives. She should definitely get her friends to help.
- Q: You know those big cranes that sometimes hang above constructed buildings. I usually thought a crane is used to build that crane but then how is that first crane that built the crane get there in the first place?
- from the ground up
- Q: Answer please~
- You know what? I thought they did but I just went through my copy again and I can't find any mention of him by name. I apologize for the incorrect answer I gave earlier.
