Characteristics of TC4808 Tower Crane

 

1) TC4808 have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.

 

2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected; The max. attached height can reach 110m.

 

3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.

The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.

 

4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.

 

5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.

FAQ of TC4804 Tower Crane

 

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 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:How are skyscrapers been build ?no cranes can be that high?
That is a good answer. Ordinary cranes build the steel frame to a height of perhaps 60 feet. The frame is designed so a specially designed crane can climb up the side (like climbing a ladder) to about 50 feet where the climbing crane can complete the frame to about 100 feet, then the crane can climb to the 90 foot level and build the frame to about 150 feet etc. Another method is the floor at about the 60 foot level is completed and extra strong. A crane is assembled on that floor and can complete the steel frame to about 100 feet where another extra strong floor is built. The crane at 60 feet is then dismantled and moved to the floor at the 100 foot level, or perhaps this is a second crane. Repeat until the full height of the building is frame work. As cranes are removed at the lower levels, more floors can be installed and some of the finishing work done. Either way, you can see why very tall buildings are very expensive. Likely both methods are used for some very large and very tall buildings. Neil
Q:How do they get cranes off HUGE buildings when they are finished building them.?
but never have I seen a set of tracks or elevator used...not to say that it isn't possible but I have only worked big buildings in NYC...maybe things are done differently elsewhere in the world
Q:Tower crane 4 how to change the rate of 2 magnification, how to change, say detailed points
There is a magnification pin on the hook group. When the magnification pin is removed, the pulley will automatically slide to the lifting trolley. At this point, the rope will be turned into 2 fold!Some manufacturers produce pulley, also need to be in the car, and then the magnification pulley with pin shaft fixed in the car!
Q:Mosquito Eater (Crane Fly) Problems?
Crane flies will probably be interested in the sunshine of the condo, so decreasing the light subsequent to the structure and what escapes from the home windows can help. They come from floor so it is rough to really do whatever to manipulate them.
Q:Who is the most gruesome Stefano DiMera or Alistar Crane?
Stefano DiMera
Q:What is the power of a tower crane? Five
TC7525-16D switchboard power 80KWTC5610-4 switchboard power 34KW.TC6015A-10E switchboard power 71.5KWThe other two types have not been touched and will not be answered. I'm sorry
Q: why use 'and to also making the cranes', not 'to also make the cranes'?
To also make the cranes is the correct way to say it. To also making the cranes is incorrect.
Q:what does Stephen Crane mean by this ?
This is a very critical and harsh poem. Stephen Crane seems to have a more pessimistic outlook on life than other poems he has written, and nowhere else does that pessimistic outlook come through in his poetry than here. The pattern of the poem affixes a cynical, satirical statement after every statement of War is kind. For example, War is kind, Hoarse booming drums of the regiment, little souls who thirst for fight, these men were born to drill and die. The unexplained glory flies above them. Especially when Crane says the unexplained glory flies above them, he is making a powerful statement by questioning whether all the death and destruction is really worth it. This questioning is very important, because many wars are not really for what they seem to be for. There are exceptions of course, perhaps World War II and the fight to end the holocaust, perhaps the Civil War and the fight to end slavery, but for the most part, wars are usually conflicts between cultures over natural resources and disagreements over cultural values. The glory of war, the patriotism, the nationalism; Crane is trying to state that all of these emotions we associate with most wars are really made up so that generally people will feel better about their actions in the long term. Crane questions whether or not war is ever really worth anything to anybody in this poem. Crane clearly does not think so, considering the level of sarcasm he uses throughout the poem, especially at the end when he powerfully states Mother whose heart hung humble as a button On the bright splendid shroud of your son, Do not weep. War is kind. This is very powerful, and Crane very clearly points out that the glory of war and honor of battle are not worth much to a parent whose son has died, or wife whose husband has died, or child whose father has died. Crane's questioning of warfare is very relevant in today's war when we are as a country in what many people would call a meaningless war.
Q:dynamic force on crane when a load of 37k falls 1',2' 3'or 4'?
Need more information. In general, the answer is that the dynamic load depends on how quickly the payload decelerates. The dynamic load will be the mass of the payload times the peak deceleration rate. In a strength calculation, do not forget to include the static weight component of the load. The deceleration depends on the elasticity of the cables supporting the load. If the crane has a flexible supporting structure, then that could also affect the result. (You didn't say whether the crane is the traveling overhead hoist type usually seen in a factory - which typically has a stiff support - or the cantilevered truss type seen on construction sites - where the support might have a little flexibility.)
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.
