FAQ of Tower Crane TC7021

 

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, we 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: could someone give me a good summary on the red badge of courage, and yes i did read the book and i have trouble understanding, and help would be good thanks!!
A kid, full of beans, runs off to join the army to annoy his mum, but on the eve of battle suddenly becomes paranoid that he'll do something to disgrace himself through cowardice. (That's actually as far as I got in the book so far.) I am given to understand, though, that in his own mind at least he does disgrace himself and endeavours for the rest of the book to redeem his manliness. In that sense the story arc, or at least the character arc, is not dissimilar to The Four Feathers. The point of the story is to counterpoint the myths of warrior gung-ho and daring-do, and to analyse the inner anxieties and motivations of the individual, volunteer-citizen soldier, and by extension the expectations of society. The novel also presents the battlefield with an unprecedented realism; that is to say, Crane presents the actual fog of war that authors have always set out to clear.
Q: Tower crane 10-5-20 is 6T, and 10-5-21 is 8T. What do you mean by tons?
6T/8T refers to the maximum lifting capacity of a tower crane. It doesn't matter what 10-5-20 has to do with it. Maybe your list of numbers is serial number.
Q: how does a crane operator's knowledge of where the centroid is generally located for most uniform objects help them perform their job more safely?
If an object is uniform, it's a fair bet the centre of mass will be at the centre of the shape. If lifting with slings, he will have them placed equidistant from centre, at an angle to each other not exceeding 60 degrees. He will then lift a little, and can tell by the angles from vertical of each sling whether or not the CM is under the centre of the crane cable. If not, he will lower the load, and have someone adjust the sling positions. Having slings equally loaded ensures a level load when lifting, and when a load is level it is a much safer lift than when it tilts one way or the other. A tilt would mean greater force in the sling on the low end. The load could slip out, or the excess force could break the sling.
Q: When the tower crane foundation is found, what should be discontinued?
The settlement, inclination and cracking of tower crane foundation can affect the stability of tower crane and should be stopped
Q: how long do i have to work as a yardhand in oilfeild to become a crane operator?
You need to get licensed or certified to operate the crane. make sure you are qualified before you start complaining about not getting more challenging work. The world needs ditch diggers to so get back to work.
Q: If anyone can find me a decent video of a Fujian White Crane Kung Fu simple hand block then I will be very grateful! I know sort of how to do it but I would like to get it spot on.Thanks
Not sure if there is a video but if you check out Analysis of Shaolin Chin Na by Dr. Yang Jwing-Ming you might find something.
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 need to know exactly how much weight they can lift also how much do they weight?how long is thier life-time?in what temprature they can work?does mosture do any harm to them?for installation , do they need foundation?the exact height and width?
You need to be more specific. The lifting capacities for container cranes varies significantly, as does any other crane. Some of the variation is based purely on load (horsepower) availability; some is based on speed (rpm) for lift/drop portions of the cycle. Cranes like these operate year-round, at ports all over the world. Some ports have average ambient temperatures in the range of 45 C, with highs up to 60 C. Others can be as low an average as 10 C, with a low peak as much as -50 C. Moisture will, over the long haul, harm them - they're metal constructs, and thus are prone to oxidation. Using corrosion-resistant materials and/or coatings will certainly prolong their usable lifespan. The crane drives (electric motors and power electronics) are also susceptible to moisture and other contaminants. All true dockside cranes require some sort of permanent foundation; it's usually part of the pier construction itself. However, there are portable cranes that operate without one. There is also more than one crane manufacturer out there - all will have their trade secrets that will make each look a little different than the rest. It will generally also reflect in their operation parameters, and in their expected life cycle.
Q: a/ Calculate the lift workb/ What is the power used by the crane when the efficiency is 60%? (Can you explain for me what efficiency means)c/ What will the kinetic energy of the load be when it hits the ground, if it falls from the height 8.5 meters, g=9.81 m/s^2Thank you.
The work done (W)= Force*Distance. Force is 9.81*3000kg. So W = 9.81*3000*8.5 = 250,155 J Power (P)= Work(W)/Time(t) = 250,155/15 = 16,677 W 60% efficiency means that the lift is only using 60% of its maximum amount of power output. So to find 100% (lets call it x) of the crane's efficiency, consider the following: x * 0.6 = 16,677 x = 16,677 / 0.6 = 27,795 W Total mechanical energy in a system remains constant, so the kinetic energy the moment it hits the ground equals the potential energy when it is still hanging in the air. Potential energy = mgh = 3000x9.81x8.5 = 250,155 J You know this is correct, because it is the same amount of work the crane performed on the object to lift it.
Q: how do they erect those large tower cranes you see on big building projects?
with another crane. assemble the tower first in sections, assemble the jib on the ground then lift it into place
