    Engineers have more than 20 years' experience in tower crane, ready to solve any of your  problems.

 

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: Can you equip with light on  tower crane  jib, monitor, remote control and anemometer?

A: Sure. All of these could be provided with extra cost upon the clients' requirements. But according to general practice, remote control is not suggested because most of the operator feedback operation in the cabin will provide a wide working view.


Q:Why are there extra placards attached to the tower crane tower?
2. after adding the placard, it will increase the windward area of the tower crane and increase the wind load of the tower crane, so that it will deviate from the calculation load when the tower crane is designed, and will affect the safe use of tower crane.
Q:Ever since a few weeks ago, these retarded giant mosquitos thingys keep on flying into my house from somewhere and they always come into my office and bother me, so im wondering what month they come and what month they leave?
Crane flies tend to live in wooded areas and open fields, but they can live nearly anywhere, including snowy northern climates and desert lands. In order for their eggs to hatch and larvae to grow into adults, they require either water or damp, decaying material in which to lay their eggs, depending on the species. Crane fly larvae and pupae can be found in damp sod or compost piles, or under the decomposing leaves on the banks of rivers, streams, ponds or lakes. Crane fly larvae and pupae feed on decomposing material, grass and the roots of many plants. This makes them a beneficial insect, as they assist in the cycle of decomposition. Once they emerge in late winter or early spring as adults, after maturing over the winter, their primary purpose is to mate and lay eggs.
Q:I'm just curious about it, and i need it for a fan fiction story i'm writing. thanks ^__^
Yes. It is genetically coded into japanese children before birth. As soon as they are born they know how to fold paper cranes. But it takes a couple of years for them to develop the hand coordination to actually do it.
Q:What should i do to solve tower crane collapse?
tower okorder / to see if whether your trouble is one of those tower crane troubles ?may be you can solve your question under its help.
Q:Is there a certain direction and reason a construction worker will leave a crane facing a certain direction.
They would generally try to point the boom (the longer part of the crane) away from the prevailing winds. This reduces stress on the tower - but it's not really a big deal.
Q:How high the tower crane needs to be installed with the wall pole. How is it stipulated in the national standard?
Beyond the maximum independent height of the tower crane design, a wall attaching rod shall be installed

Fujian White Crane is also known as Yung Chun Pey Hok in the Fujian dialect. I will standardise the Chinese terms in Mandarin. So, Fujian White Crane is Yung Chun Bai He(r) It is a Lan Pai (nam-pai) chuan. The 'nam pai chuan' that you refers to is a synthesised competitive form with elements from a few well-known Lan-Pai styles, like Hung Chia. Lan pai refers to all Chinese Martial Arts originating south of the Yellow River. So, Fujian White Crane is a lan-pai, JKD is also a lan-pai as it draws techniques from Yung Chun (Wing Chun in Cantonese) which itself is a lan pai, being originating in Foshan, Guangzhou. Fujian White Crane is a complete martial arts system in the 'lan-pai' sense. Except for the movies, it has all that the asker is looking for. As in most cases, Fujian White Crane is a general name of a family of White Cranes with each style closely resembling to each other yet with different emphasis in attack and defence techniques. I think that there are about three types of Fujian White Cranes. Why in the lan-pai sense? Comparatively speaking, between the Northern (bei) and Southern (lan) martial arts, the latter do not have wrestling. To the Northern martial arts, bei-pai, Mongolian wrestling is part of the syllabus and that completes the wholeness of Chinese martial arts.
Q:It's got to be the most famous of all designs in the art.
I can actually I made a thousand of them one time I learned in 8th grade and it stuck with me.
Q:ok so i have to us my phone so just give me instructions no links no youtube videos cause my phone cant support them and my phone may not be able to load some of the links
You are asking for a lot but I have seen you request this a number of times, so I will do it...a sucker born. 1. Valley fold the paper in half so it makes a triangle. With the long side held away from you, valley fold the triangle in half again. 2. Lift the top triangle and valley fold it so that its top point meets its bottom point. Unfold the crease you have just made. Put your fingers inside the top triangle, open it up, and flatten it so it forms a square. Turn the paper over and fold and flatten the remaining triangle in the same way. 3. Make sure that the open ends of the paper are pointing down. Valley fold the top layer of both sides in to meet the centre crease. You will now have a kite shape. 4. Valley fold the top point of the kite down and crease well. Unfold the crease you have just made. 5. Open the sides of the kite by unfolding the flaps you made in Step 3. Lift the top layer of the kite's bottom point up so the paper bends at the crease you made in Step 4. Push the outside edges of the paper in to meet the centre line. Then flatten the figure so that you have a long diamond shape. 6. Turn the figure over and fold a kite shape on the remaining side as in Step 3. Repeat Steps 4 and 5 on this side. You will now have a two-sided long diamond. The bottom half of the diamond is split in two. 7. Valley fold the top layer of both bottom edges in to meet in the middle. Turn the figure over and repeat on the other side. 8. To make the crane's neck and tail, valley fold each half of the bottom section out to the sides. Crease well. 9. Unfold the right crease you just made and make an inside reverse fold. Repeat this step on the left side. 10.To form the head, fold down the end of the neck. Unfold this crease and inside reverse fold the head. 11.Hold one of the crane's wings in each hand. Blow hard into the opening on the underside of the figure and gently separate your hands. You crane will puff up and be ready to hang.
Q:Is a crane a type of pulley?
No. A crane is a machine to lift heavy things. It usually uses a pulley. A pulley is part of the crane.
