Product Description:

Brief Introduction:

 

1.Overall haulage with only a 5t vehicle for whole machine transportation. Haulage size can smoothly pass all standard bridge and culvert.
2.After quick erection, it can start working normally within one hour.

 

3.Correctly-positioned mechanism kinematics spacing.
4.High precision and reliable load moment limiter and load lifting limiter.
5.Special system: wheelbarrow persist axis break
6.Two purpose: arm-brace fixing and orbit walking
7.Overall haulage bridge can be easily altered into a transport tow (10t)
8.35m height and could be used 30 degree higher up

 

9.Crane body locked automatically, crane jib docked automatically, pulley at jib point positioned automatically. There is no artificial high-altitude operation through the whole erection and dismantling process.

Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
1. Tower crane consists of three parts: metal structure, working mechanism and electrical system. The three main technical parameters are lifting moment, lifting weight and working speed. Lifting moment refers to the boom as the basic arm length maximum amplitude corresponding to the rated lifting weight of product, product or maximum weight with the corresponding inflection point.
Q:What should we do after folding the 1,000 cranes?
I've only heard of putting them up on strings and you could give them as gifts .. Oh and you could also frame them by laying them flat
Q:what batteries fit in the JG 614 crane stock version can i have links to buy i do not like airsoft megastore?
I would suggest that you replace your sub C batteries to lipoly batteries. This will fit your crane stock perfectly and still has room.
Q:in the short story open boat by stephen crane how does he define Fate?
Without doing your work for you, Crane is a naturalist. They believe nature works at random, and is completely unsympathetic to man's plight in the process. Hence, the oiler dies. He was probably the strongest one in the boat. So, how does that translate into the concept of fate?
Q:Should I give my boyfriend an origami crane?
let the whole origami thing be his thing big mistake to give him the crane
Q:How do they erect HUGE cranes without a crane?
They use Hydraulics. I don't know if you have any understanding of Fluid power but a hydraulics system can lift up to 400% of its weight multiplyed by its density. There are other factors to consider such as cylinder size, flow, and pressure but these are usualy constants. For example: If the hydraulic fluid used weighs 5 lbs. per gallon and its density is .9 gram per cubic centimeter then 1 gallon of this fluid could lift 53.1441 lbs. A jack system is hydraulic
Q:Air Hogs Fly crane wont fly?

Q:What is the worlds heavy-est crane lift?
the lift capacity of the Crane is pretty much dictated by the type of crane it is. The largest Gantry / Bridge type is capeable of 1,500 tons.. the largest tower is 100 tons w. a 100meter turning radius. Tracked lattice boom type is 1,600 tons...........(self contained) there's one that will do 4000 tons with modifications including seperate tracks for counterweights
Q:how do they erect those huge cranes for constuction?
As described above, but the crane that is being used in our plant arrived in 80 semi truck loads!
Q:How crane can hold huge counter weights? Why CG is not changing while adding counter weight on cranes?
Usually the counterweights can move back and forth on an arm. They are moved toward the crane when there is no load and away from the crane when there is a load. If the counterweights can't move, then the crane must be designed to hold (at least) the minimum counterweights in their fixed location. As the crane gets loaded, the net moment decreases, and then increases in the other direction as more and more load gets added. It is still likely that the maximum design moment when loaded far exceeds the moment due to the counterweights on an unloaded crane.
