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.

Q: the lenght of beam is 4.5mmaterial of beam is ASTM Gr60
Not enough information. What is the load weight? What is the size? How do you plan to attach to the machine. What size is the beam cross section? Capacity of the cranes? And so on. It sounds like you might need an engineer to supervise instead of relying on Yahoo Answers for an answer to a potentially deadly if not expensive way to fail.
Q: How to choose tower crane in engineering, such as arm length and lifting weight?
1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.
Q: How do you win something from those crane machines in stores?????
You dont!! Most times as said its luck. The toys and goodies weight alot so its hard for the claws to lock on to them.
Q: Tower cranes sometimes have very long booms, but seem to usually have fixed counter-weights at fixed positions behind the cab. Why doesn't it flip backwards when there is no load, or flip forwards when a load is way at the far outward end of the boom? It seems to be a very large range of moment arms given that the counter-weight has a fixed one.
I think the counter weights are connected to a pully system that directly interacts with the boom and hook movement. This way it can put more or less pull on the weights according to the amount of weight or position of the weight on the crane.
Q: Examples of filling and acceptance forms for tower cranes and examples of filling in.
The 1 conclusion is "qualified" project, fill out the "tick".2, the conclusion is "unqualified" project, fill in "x"". Part of the "unqualified" sub item should also be painted on its number *".

Q: I have to create a crane to support a dead load for my Engineering Technology class. It can be made out of only 1/8 inch balsa wood and wood glue, and is going to be graded by the ration of weight held to structure weight.Could anybody give me some suggestions as to how to go about designing this thing? I already know most of the basics, but if anybody could give me some specific tips, they would be greatly appreciated.Thanks!
Balsa Wood Crane
Q: First Summary gets best answer...thanks!
The City is covering itself by shifting the blame form a negligent city inspector to the crane company by charging its owner with Manslaughter Charges. This is typical of civil service personal who forget who they work for (We the People).
Q: Is the crane a metaphor for the woman? Or does it transform into one? OR does the guy marry a bird? I've been listening to this all week and cannot discern which is right...maybe that was Colin's intention? A little help here?
It's a story about a peasant living in, I assume, rural Japan, it being a Japanese folk tale. He finds a wounded crane on the road as he's walking one night. It has an arrow in its wing, and he pulls out the arrow and revives the crane. A couple of days later this mysterious woman shows up at his door and he brings her in. Eventually, they fall in love and are married. Although they're poor-- she's a seamstress, a weaver-- she suggests that she can make this cloth that he could sell and make money. But the one condition is that when she's weaving he can't look into the room at her weaving. This goes on for awhile, until eventually the peasant's curiosity gets the best of him and he looks in. It turns out that the woman is a crane, and she's pulling feathers from her wings and putting them into the cloth, which is what makes it so beautiful and soft. Apparently, having looked in at her breaks the spell and she turns permanently back into a crane and flies away.
