FAQ
Q: What is the difference between CNBM and CMAX?
A: CNBM stands for China National Building Materials (Group) Corporation, which is established in 1984, is the largest state-owned group corporation of building material & machinery with a total asset of 15 billion USD and a staff of 100000.
CMAX is the brand name of CNBM Group’s construction products, C stands for China and Max stands for Maximum.
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.
Second, we need to know what the foundation requirement from the client is. (Fixed/undercarriage/ undercarriage with traveling system), mast section type (panel/integrated), power supply source (voltage, ampere and frequency), the distance between the machine and power supply……
Third if there are special needs, CNBM could suggest proposal according to clear data provided by the clients. End-user, as construction machinery buyer, knows the site situation well and should make decision, such as the machinery specification, type…….
Q: What about our tower crane's 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.
To Lead The Revoluation of International Trade
- Q: what can lead tower crane to blank out?
- （1） tower crane has crack; （2）Brake block friction lining wear up to 50% ofRaw material thickness ; （3）Brake wheel surface wear reaches 5mm ~ 2mm （4）Spring has plastic deformation; （5）Lever system, air travelis more than about 10% of its rated trip
- Q: There is no CAD map attached to embedded parts of tower crane?
- What size do you want?. Each model is different. For example, the 5010 tower bolt embedded needs 24.
- Q: What are the basic parameters of a tower crane?
- The basic parameters of a tower crane include the length of the crane itself, the weight of the crane as well as the weight of the counterweight! Tower crane lifting mechanism; slewing mechanism; luffing mechanism; motor power;...

- Q: I was wondering if this is possible. The wall we have designed is very close to an existing retaining wall. In order to properly form and waterproof the wall we would have to demo that existing retaining wall. My idea was to build it off site, waterproof it, and then crane it into its location. Is this possible? any similar methods? thanks
- Possible but difficult. You could tell us what the wall is made of? Assuming stone, then you can't lift a stone wall unless you have a steel plate under it, as it will collapse otherwise. That gets complicated. Yes, you could build it with a 1/2 inch steel plate under it, and lift it that way, assuming it is not too long, and crane it into position, but you then have to slide the plate out without cracking the wall, also difficult. The plate is expensive, the crane is expensive. But what do you gain? You still have to demolish the old wall, you still have to build a new one, so what would you gain by building it somewhere else and moving it?
- Q: They like fly on peoples face, i dont know why they come up on the face and it creeps me out, i have no idea why it comes inside of the house in the first place?
- They come inside the house looking for mosquitoes! Crane Flies are great mosquito hunters, in fact we call them skeeter eaters. I'm from the south, plenty of mosquitoes here and we love Crane Flies. They're totally harmless to people or anything else besides mosquitoes, and since mosquitoes are proven carriers of numerous deadly diseases such as malaria, yellow fever, and the dreaded Nile virus, I'd much rather have Crane Flies around me than mosquitoes. Do yourself a favor and learn a bit more about these fascinating and very helpful critters, I'm sure you'll be willing to cut them a little slack if you do. edit Leolupus is correct! It turns out after 40 years I was completely wrong ~ they do *not* eat mosquitoes. I have been informed by an expert (my father-in-law, who is an entomologist at Texas AM and laughed at me when I mentioned this question my answer) that adult Crane Flies eat flower nectar, decaying vegetation, seedling plants, mosquito larva (but not adult mosquitoes) or nothing at all depending on their species. They are, however, harmless to humans since they're totally unable to bite, though they're considered a pest by some farmers due to the habit of some species of dining on young crops. Oh well, sometimes you start out trying to teach someone a lesson and you end up learning one instead. Thanks for bringing up this subject, Bebe :-)
- Q: My Sister gave me a Russian Lacquer box with two flying cranes on it. There is supposed to be a story behind the cranes, but I can't find it online. Does anyone know where I can find this, or happen to know what the story is?
- Cranes are believed to bring good luck to people. So you are double lucky in this case; or perhaps even triple lucky since you have a thoughtful sister who have you such a lovely gift. Russian lacquer is magnificent. Nothing like it in the world.
- Q: In the end of chapter 16 of Catching Fire the 2nd book of the Hunger Games it says the name she wrote in the dummy, was Seneca Crane. Who is that?!,
- Seneca Crane was the man who ran the Hunger Games in the year that Katniss was in it. He was killed in the end because in the time HE ran the games, TWO people were allowed to win, and President Snow had him killed. It effected the Gamemakers when she wrote it on the dummy because they were shocked and reminded about punishments if they run the games wrong.
- Q: A crane lifts a 425 kg steel beam vertically a distance of 117m. How much work does the crane do on the beam if the beam accelerates upward at 1.8 m/s^2? Neglect frictional forces.a.) 3.4 x 10^5 Jb.) 4.0 x 10^5 Jc.) 5.8 x 10^5 Jd.) 4.9 x 10^5 JSolved as W= mgh but obviously that is wrong. Where do I go wrong?
- You have the right idea, the answer is d. EDIT: Well I actually read the rest of the question (sometimes I get an itchy trigger finger!), and the net force should be found first, the net force includes the weight and the tension in the crane's cable (so you need to find the tension): ∑F = ma = T - mg T = m(a + g) = 425kg(1.80m/s? + 9.80m/s?) = 4930N So the net force is the sum of the tension in the cable and the weight of the beam, or: F = T - mg = 4930N - (425kg)(9.80m/s?) = 735N Then, the work done by the crane is: W = FΔy = 735N(117m) = 8.95 x 10^4J Does not match any of your choices, so I am perplexed! Maybe someone will straighten me out. Apologies if I failed to help.
