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 mobile crane has a weight of 116kip and center of gravity at G1; the boom has a weight of 29kip and center?
The key here is to simplify this as much as possible The equation is really: mass 1 x length 1 + mass 2 x length 2 = mass 3 x length 3 G1 * 6 ft = (G2 * X ft) + H3 * X ft) G1 = 116 kip G2 = 29 kip H3 = 38 kip Now it is an equilibrium of torque about the point where the boom pivots: 116 kip * 6 ft = 29 kip * Xft + 38 kip * Xft solve for X feet: X feet = 10.388 ft So the crane is in equilibrium when the load is length1 + length 2 times the mass = mass of motor * length 3 (10.388 ft * 29 kip) + (10.388 ft * 38 kip) = 116 kip * 6 ft The boom forms a triangle with the hypotenuse equals 12ft + 15 ft = 27 ft. The bottom of the triangle is 10.388 ft + 10.388 ft = 20.776ft So we have two sides of the triangle and now just need to find the angle where the triangle forms with those two sides: cosine of angle = adjacent side / hypotenuse cosine of angle = 20.766 / 27 = 0.7691 and the arc cosine of that = 39.7 degrees So rounding it off, angle of crane = 40 degree
Q:Do cranes only watch water when theres fish?
They also eat bugs and little critters. It could have been looking just outside of the pond, also it could have not known there weren't any fish and thought to give it a try anyhow.
Q:I am a fellon, I made a mistake and I need help getting my crane certifacation. so I can work.?
lol, yeah, how about just flip my burgers.
Q:Any opinions on camera cranes?

Q:why does the power company use helicopters to service the repair lines instead of trucks with tall cranes?
High-tension lines operate at hundreds of thousands, or millions, of volts. At this potential, electricity can jump through several feet of air to reach a path to ground. This pretty much rules out using trucks, because it would be prohibitively expensive or impossible to build a crane out of entirely non-conductive materials. A helicopter is electrically isolated from the ground, so it's less difficult to drop a technician off and let him hang from the line itself while working. (It is still necessary for the technician to use a wand to bring the helicopter to the line's potential before starting work, because of the capacitance of the helicopter's body.) They could of course use a truck to service the lines if the power was disconnected, but the cost of shutting down service to an entire region of the country exceeds the operating cost of a helicopter.
Q:Who do you think would win in a battle between Roger Thorpe and Alistair Crane?
alistair crane has nothing on roger thorpe. it wouldnt be a battle, roger will make alistair look like a clown.
Q:Is there a crane big enough to lift Hillary off the yoga matt when she has finished her yoga?

Q:What would be a nice [short] Qur'an ayat or hadith to put on a paper crane?
Walaikum Salaam, So patiently persevere: for verily the promise of Allah is true: nor let those shake thy firmness, who have (themselves) no certainty of faith. al-Qur'an 30:60 'Never let your enmity for anyone lead you into the sin of deviating from justice. Always be just: that is closest to being God-fearing.’ (al-Ma’idah 5:8) ‘The flesh of sacrificial animals does not reach God and neither their blood; but only godliness from you reaches Him.’ (al-Hajj 22: 37) Hope I helped sis! :)
Q:Demoiselle Crane chick not walking or standing on its legs?
Your baby crane might have stepped on something, But this is nothing like malnutrition, From what ive learned the crane may have a joint dysfunction in the knee but this very common in cranes, I really think you should take an X-ray of the cranes legs because,(and the baby cranes feet will expand over time) This could get worse. This is more than likely a leg dysfunction. Hope this helps.
