QTZ4208 FAQ
Q: What kind of steel used for tower crane?
A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.
Q: What is tower crane?
A: Tower crane is a modern form of balance crane that consist of the same basic parts. Fixed to the ground on a concrete foundation (and sometimes attached to the sides of structures as well), tower cranes often give the best combination of height and lifting capacity and are used in the construction site.
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: What is the function of the monitor?
A: Monitor, namely inspection system (like black box), which could store 10000 tower crane operation reports, and it is recommended to be installed in big cranes more than 16t.
- Q:How do they get the cranes and counterweights down off the top of buildings when finished?
- Dereks, which are built along side of the buildings, actually take themselves apart. There is a jacking system which attaches to the segment that is 2nd from the top. This lifts the bussiness end of the crane off the top segment which can then be unfastened and lowered to the ground. The jacking system then replaces the crane on the new top, travels down one more segement and the process is repeated. It is actually cool to watch.
- Q:Jon and Paul are folding origami cranes. If Paul works alone he can fold 100 cranes in 5hours. together they can do the same job in 3 hours. how much time would it take for Jon to fold 100 cranes alone? Please show your work. :)
- Paul does 100 cranes in 5 hours So in 1 hour he does 20 cranes In 3 hours he does 60 cranes and balance 40 cranes Jon does Jon = 40 cranes in 3 hours So 100 cranes = 100/40 X 3= 7.5 hours ANSWER
- Q:How can you tell the difference between a mosquito and a crane fly?
- Crane flys are much larger than mosquitoes. They look like mosquitoes on steroids.
- Q:How to calculate life span of steel structure? for example, crane?
- this type of calculation is a fatigue life calculation, performed (for example) on aircraft. You will have to know the material, the load spectra and the stresses for this load spectra. It is not an easy, nor exact calculation. Try reading some fatigue topics on the reports suggested on the source site.
- Q:What is the function of the balance valve in the hydraulic jacking system of tower crane?
- The function of the balance valve is to maintain the balance of the oil pressure, the hydraulic oil delivery flow is stable, so that the tower crane jacket and the upper part of the lift, disassembly, standard time, lift and smooth.
- Q:in design of steel structures as per asce2005 or ibc2006 ,what load combinations are to be considered when crane loads and seismic loads are present?
- Asd Load Combinations
- 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:crane operator?
- Ya dude--truck driver---your turn
- Q:the highest ranking American serviceman, at least in the so called prison camp
- Bob Crane did not commit suicide. His head was caved in with a video camera tripod while he was in bed, presumably, asleep. This happened at a time when he was doing dinner theater in Arizona. It is believed that a male friend of his who liked hanging around with Crane did the deed as Crane was seeking to end their friendship. Crane was a chick magnet and very interested in video taping his encounters with women. This friend of Crane's used to pick up the leftovers that Crane didn't sleep with and thus the reason for his being angry when Crane wanted to end the friendship.
- Q:when a tall building is under construction you alwase see cranes on top. well i would like to know 1. how they move them up as the buildung gets taller and 2nd after there done how do they get them down?
- They disassemble them
