Inquires QA:
My dear friends, If you need any towercranes, please tell us the below basic parameters:
1. Building height or tower crane workingheight.
2. Max load capacity and tip load capacity.
3. Span or jib length
4. Other Special requirements
Welcome to contact us! Believe will be your best choice
- Q: What are the characteristics of a tower crane?
- Two, according to the structure characteristics of the boom can be divided into the pitching amplitude boom (boom) and trolley jib tower crane (arms).Luffing jib tower crane luffing jib by lifting does not achieve the amplitude, the utility model can give full play to the effective height of the boom, simple mechanism.Trolley jib tower crane is installed on the level of the boom on the track trolley achieve amplitude, the utility model has the advantages of large amplitude range, trolley can near the tower, can load amplitude, the shortcoming is: the boom stress on the structure of complex, high requirements, and the boom and the car must be in the building the upper part of the spire, the installation height should be higher than the roof of buildings 15-20 meters.Three, according to the turret structure, the rotation mode can be divided into lower slewing (turret rotation) and upper slewing (turret not slewing) tower crane.Under the rotary tower crane slewing bearing, balance weight mechanism are arranged on the lower end of the main tower, its advantages are: less bending, low gravity, good stability, convenient installation and maintenance, the disadvantage is the higher requirement to the slewing bearing, installation height is limited.The slewing tower crane is characterized in that the slewing bearing is balanced and the main mechanisms are arranged at the upper end, and the advantage of the utility model is that the lower part of the tower body can be simplified, and the lifting and the adding of the joint can be simplified because the tower body is not turned. The disadvantage is: when the building exceeds the tower height, due to the influence of the balance arm, limit the slewing of the crane, at the same time, the center of gravity is higher, the air pressure increases, the weight increases, so that the total weight of the whole machine increases.
- Q: Safety rules for tower cranes
- Three. Check after shutdown3.1 after the tower crane has stopped operation, it is necessary to select the suitable position of the barrier and the middle of the track when the turret is turned and the arm to stop along the wind, and then lock all the rail clamps.All 3.2 tower crane rotary mechanism with a normally closed or braking device, in the stop after the operation, the driver must remove the handle, release the brake for crane in the wind blowing in under the direction of rotation.3.3, the hook should be lifted to the minimum distance from the lifting wall, not more than 5m position, hanging on the hook is strictly prohibited. Not to take reliable measures, not by any means, limiting the boom rotate with the wind.
- Q: How the cranes can stand without any tipping with huge counter weights on its back? If there is no suspended load also the crane is is still stable with huge counter weights on its back. How it can possible? Why crane is not offballencing while we adding extra counter weights on it without any suspended load?
- Usually the counterweights can move back and forth on an arm. They are moved toward the crane when there is no load and away from the crane when there is a load. If the counterweights can't move, then the crane must be designed to hold (at least) the minimum counterweights in their fixed location. As the crane gets loaded, the net moment decreases, and then increases in the other direction as more and more load gets added. It is still likely that the maximum design moment when loaded far exceeds the moment due to the counterweights on an unloaded crane.
- Q: Our company is responsible for the general contracting construction project foundation pile by Party A but other subcontractor for the construction of pile foundation of a pile foundation the company has quickly completed the construction scheme of the party and the supervision of tower crane foundation now has been reported by the audit Party B must contact us pile pile. We believe that Party A shall bear it at one time. Ask the net friend is this so?
- In fact, in the long run, in a word, what the construction site is finally all party a pay, just clearing the count.
- Q: When making 1000 origami cranes, do all of them have to be the same size? I already made some of varying sizes. Does it matter? I hope not.Thank you.
- i don't get it. who's going to furnish you a desire? The magic crane genie? Buddha? Why no longer attempt praying to God who might have the potential to help you, without going to each and all the artwork and giving your self paper cuts.
- Q: It got me thinking.
- I have not seen the movie, but I think I saw what you're talking about on a preview. I would think that the safeties involved in the control system for a crane would make it highly unlikely to happen. There is no absolute assurance, only probabilities or likelihoods. You just hope that you have enough failsafes in the system so if one part of the system fails, the others will take over, or shut the whole thing down properly.
- Q: Cranes are normally used in construction in most countries.But I saw some photos that show Iranians are hanging criminals in pubic with cranes instead of gallows.Is it more painful to the dying criminals to the last moment?Do you know why?
- they probably didn't have the proper arrangements to carry out the punishment so they used cranes instead of gallows. who knows? but weird really. and it wouldn't be more painful... err... the purpose is to snap the neck... ouch :(
- Q: What does "jack up" tower crane 1000KNm mean?
- 1000KNm means that the rated lifting moment of the tower crane is 1000KNm. That is to say, the 100tm tower crane.
- Q: A crane operator was extended his Tadano crane boom(two section of boom out of five) at almost 0 degree boom angle. My question is-Is it safe to lift any load at 0 degree boom angle.
- The answer is yes. The amount of the lift weight depends on the weight of the counter weights on the back of the crane. There is an indicator (printed or electronic) which indicates the maximum lift based on angle and extension. TexMav
- 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.
