QTZ40(TC4808) FAQ
Q: What is the principal to quote the right tower crane to the client?
A: First, we need to know clients’ requirements. Normally the following information should be clarified by the client: max lifting capacity, height (height under hook), tip load and jib length.
Q: What is 3 main mechanism of the tower crane?
A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.
Q: What is the principal to quote the right tower crane to the client?
A: First, we need to know clients’ requirements. Normally the following information should be clarified by the client: max lifting capacity, height (height under hook), tip load and jib length.
Q: What can we do for the clients in the market and after-sale service?
A: There is branch office for us in the kingdom and she could provide any commercial assistance for the clients; our exclusive agent would fully represent lifting machinery for business communication and rapid & professional technical support.
- Q: Is there an effective utility for estimating the required size of a crane? I’m an estimator for a mechanical contractor, and it seems we never allow enough money for crane rental. How can I effectively adjust my estimates?
- The only effective way to estimate the size of a crane when needed is to know, without a doubt the weight of the heaviest thing that you have to lift, and allow at least a 20% margin for safety. This is standard practice in building bridges, in particular - the weight of EVERYTHING is clearly marked, or just generally known. If there are bridge segments to load on a barge, for example and the heaviest segments are 220 tons, then a 300 ton crane is used. Always err on the side of safety.
- Q: A. Designated operatorsB. All construction site personnelC. InspectorsD. All of the above
- Crane are extremely dangerous and complicated machinery , the operators need intensive education and training , they have to pass the required tests to be certified . Now even the signal guy on the ground who helps the crane operator needs to be certified . So your answer is A.
- Q: determine the maximum load the crane can support in kg if the bending moment on the beam is not to exceed 5000 Nm and the shear force is not to exceed 3KN when the crane is positioned at mid span
- figure shear first Let F be the max. crane load. for a simply supported symmetric load, the reactions at each end support will be half the total load. The reaction loads will also equal the shear load. 3000 N = (F + 150(9.8))/2 F = 4530 N The maximum bending moment will be the shear force times the moment arm of half the joist length 5000 Nm = [(F + 150(9.8))/2] N (2.0 m) 5000 = F + 150(9.8) F = 3530 N The bending moment max load is 1000 N less than the Shear max load so bending is the limiting factor The maximum load allowed is F = 3530 N 3530 / 9.8 = 360 kg As a form of exchange, please remember to vote a Best Answer from your results.
- Q: What is the difference between a tower crane and a jack up tower crane?
- The fixed tower crane means lifting the foundation of the tower body on the foundation or structure through the connecting piece.
- Q: I'm into urban exploration and basically the one thing I haven't done is climb a crane. I don't actually know where one is that I could climb, but I definitely will do it someday. I'm just wondering how illegal it would be? Also, don't give me any it's not safe bull, I'm perfectly confident in my abilities and ready to accept the consequences if I get caught.
- Not at all if you don't get caught. However cranes are private property, you'll get your a.ss handed to you if you get caught.
- Q: Can the attached arm of the tower crane be welded?
- The attached arm of a tower crane can not be welded and can only be bolted.Adhesion calculation of tower craneTower crane attachment (anchor) device structure, internal force and installation requirements in the use of narrative instructions so in the tower crane installation and use, the use of units can be executed according to the requirements, do not need to calculate, only when the tower crane installation position to the building from the over manual provisions, to increase attached rod (Zhi Chenggan) two, spacing or attached rod connected with a building when changing to attached calculation.
- Q: how do you make an electromagnet crane?
- Well I guess you would need a big electromagnet, a large power source and a crane. You would need to wind a huge coil around an iron bar, feed it with lots of direct current and stick it on a crane.
- Q: explain thoroughly please
- Sure. Let's say that a crane needs to hoist a load of 10 tons, and that because it needs to reach over some obstacles, needs to lift at a horizontal distance of 50 feet away. That creates a torque about the base of the crane of 500 ton·ft. By positioning a counterweight on the opposite side of the tower, the magnitude of the moment can be mitigated. For instance, let's say a counterweight of 10 tons is positioned at 25 ft on the other side of the tower. The moment produced by the counterweight is 250 ton·ft, so the net moment at the base is 250 ton·ft. Furthermore, when the 10 ton load is positioned and release, there is still a 250 ton·ft moment at the base of the tower; it has simply switched direction (say from rotating the crane to the right, to rotating it to the left). If you find this helpful, please award Best Answer!
- Q: what does a paper crane represent/symbolize?
- A fun activity to do when you have nothing else to do!
- Q: Is there a world record for making paper cranes?
- Yes! To commemorate the fiftieth anniversary of the dropping of the atom bomb on Hiroshima, two hundred thousand folded paper cranes were completed by December 15th 1995. Each crane had someone's name and peace message written on it. The intention is to preserve them to hand on to the 21st century. The event was sponsored by the Hiroshima International Cultural Foundation. There are other cool facts at the website below like the world's largest paper crane, most cranes in one hour, etc.
