Description of our Tower Crane
1) TC60/10 tower crane is one of the key product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.
2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected
3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.
5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.
Advantage of our tower crane
1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.
2, suitable for the group of tower cross homework.
3, boom stability is good, combination amplitude range.
4, suitable for height have special requirements occasions construction.
5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

- Q: Does anyone know of any companies that sell mobile cranes suited for extreme cold? I'm aware of Liebherr and Havator's harbor cranes, but I can't find much else.Thanks
- this is not my area of study but i will give you something to consider. if you are looking for a large capacity crane for use on permafrost, you wont find one. the pressure placed on the permafrost by large weights will cause it to melt. anything that is heavy, like a house, will sink in the tundra just like it will in a swamp. for houses they excavate the foundation a build a giant wooden raft that the hose floats on. in ST Petersburg, Russians preferred a mix of reeds and slave laborers corpses's to build the raft. as long as the ground is not frozen there is somebody how makes what you want. if the ground is frozen, you will only find small machinery. best of luck ps dont look to hard. lots of diesel engines work great at sub-subfreezing temps.
- Q: I need to do a report on how cranes topple, moment (physics) and there correlation (relasionship).I am an idiot and have forgotten what moment is. so please explian that, how cranes topple and why they dont topple, and the correltion between the two!thank you
- First of all, let's think of a crane like a giant see-saw, where the plank itself doesn't have any weight. Now cranes have big weights on one side of the pivot, which they can move along (I think, I may be wrong). These cause what is called a 'turning moment'. The further out from the 'pivot' they are, the greater the moment. The other consideration with a crane is it's load. Generally, this is carried a lot further out from the pivot point, on the opposite side from the weights. Now consider this. If you have a small child sitting on the end of a see-saw, you will be able to balance them with a larger person sat closer to the pivot. This is the principle on which cranes work. The moment is the force times the distance from the pivot, and it must be balanced turning each way for the see-saw/crane not to topple. This is somewhat of a simplification, but hope it helps.
- Q: the cable of Crane I creates and angle of 30 degree angle from the horizontal and the cable of Crane II creates an angle of 45 degrees from the horizontal.-draw a figure that gives a visual representation of the problem-write a vector to represent the tension on the cable of Crane I-write a vector to represent the tension on the cable of Crane II-write a vector to represent the 20000 lb cargo container being lifted -calculate the tension on both cables. Justify your answer.....please help me!!! thank you!!!!:)
- So I can't tell whether the cargo container is one ton (2000 lbs.) or ten tons (20,000 lbs.). For doing the problem, I'm using 2000 lbs., so you might have to multiply the answers by 10. Also, I'll use A and B for the cranes instead of I and II. (Vertical): A sin 30° + B sin 45° = 2000 == A + √2 B = 4000 (Horizontal): -A cos 30° + B cos 45° = 0 == -√3 A + √2 B = 0 Solve those equations simultaneously to get A = 4000/(1+√3) = 1464 lbs. and B = √(3/2) A = 1793 lbs. (Answers) The vectors are: A = 1464 (-i cos 30° + j sin 30° = -1268i + 732j (Answer) B = 1793 (i cos 45°i + j sin 45°) = 1268i + 1268j (Answer)
- Q: How do they get big cranes up on skyscrapers for renovation? and how do they bring it down? And where they keep the cranes after done?
- with other cranes and lift systems. When done, they move on to the next project.
- Q: Cranes nowadays are MASSIVE! but something that has been bugging me for ages is how do they get the massive crane bit at the top down once they have finished constructing the skyscraper/building?
- A okorder /
- Q: is was about making this game where this guy knows crane style
- Like Sensei Scandal wrote, crane style is very rooted. No flips or crazy jumps so it is not acrobatic in that respect. Posture and balance is extremely important to the power generating methods crane style utilizes. The clips Scandal provided are very good and do demonstrate the posture well. If you look closely you can see quite a bit of modern karate in them.
- Q: I got the crane gold 1.6 roller rocker I'm trying to install on my 95 z28 w/ an lt1 and it doesn't seem like they are installing quite right. I got the tall black nuts that hold the rocker down around the stud and the pushrods, that's it. Do I need to use those things that go below the rockers themselves (the things that slide over the stud and the rocker goes over it from the original rockers) or do I just install how I already am with just the crane rockers, black nuts and pushrods?
- Lt1 Roller Rockers
- Q: any1??
- forces for cranes are dynamic , so u'll have repeated cycles of compression tension ( i assume it's a trussed crane). but generaly for a cantilever , the main forces are -ve Bending Moment +ve shear which changes the rft. bars position if dealing with R.Concrete for example
- Q: i have a female Doberman 4months old. running here n there, we spend time with her morning and night, four days per week we go to a big ground and walking with her more than a hour per day, is it adequate? she seems very happy and waiting for us on every evening (me and my wife) also i need an advice on her crane? i have put her in some what big (5ft 4ft) place beside my front door, not fully covered but well sheltered by the house roof/. is it ok to have an open crane like that?
- NO!! bl
- Q: Whenever a vista shot of London comes up, there are a ridiculous amount of cranes. What's up? Are they always building something?
- Cranes are used in the construction of buildings. It is the Storks that bring the Babies
