Span: 40m
Place of Origin: China(Mainland)
Model Number: TC4808
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:what can lead tower crane to blank out?
- （1） tower crane has crack; （2）Brake block friction lining wear up to 50% ofRaw material thickness ; （3）Brake wheel surface wear reaches 5mm ~ 2mm （4）Spring has plastic deformation; （5）Lever system, air travelis more than about 10% of its rated trip
- Q:I caught this crane fly in my garage but is almost the size of a dragonfly. It has a 3 inch wingspan. I saved it in a jar because I though no one would believe me. so do they really get this big or is this thing a freak?
- the answer is yes.
- Q:What windproof devices should be set up for crane work?
- 2. torque limiterTorque limiter is an integrated safety protection device for jib cranes.We know that an arm crane represents the load condition from the moment of gravity. The load moment value is made up of product weight, amplitude decision, amplitude value is determined by the product, the boom of the crane arm length and angle cosine so that the crane is overloaded, in fact are the weight, arm length and arm angle limit, while also considering the working conditions and other parameters as well as constraints effect of control is more complex.At present, the widely used microcomputer controlled torque limiter can synthesize various situations and solve this problem better. The torque limiter consists of a load detector, an arm length detector, an angle detector, a work condition selector, and a microcomputer. When the crane to enter the working state, the computer will detect the signal input parameters of the actual working state, after operation, amplifying and processing, and advance into the rated load moment value, and at the same time in the display to display the corresponding actual values. When the actual value reaches the rated value of 90%, it will issue a warning signal when the actual value exceeds the rated load when the alarm signal, at the same time the crane to stop dangerous direction (lifting, boom, arm and rotary movements continue to drop).
- Q:Tower cranes, TC7525-16D, TC5610, TC6015A-10E, ZJ5910, D800-42, the power of these models is how much ah?I hope you can help me. I'm in a hurry!! Thank you！
- 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:These cranes always stay higher than the construction process but I have never seen how they are extended to stay above all of it. They come in two formats, free standing and those attached to the building. The possibilities that I thought of was that maybe they use another crane to lift the housing and the horisontal arm to put in more modules into the vertical part; or that they extend it by some way by putting modules in at the top or bottom and that the crane has some self-lifting mechanism to accommodate the insertion of more modules. However, I have never seen this being done, nor does the construction of these cranes point to its ability to do so. The only other possibility that I could think of was that the crane is set up at the outset to be higher than the completed height of the building, hence there is no need to extend it but this does not explain how they do it for very high buildings where the crane is attached to the building and seems to grow higher with the building.
- The cranes are self erecting. The cranes tower is raised in sections. The lowest section is jacked up to the correct height and then a new section inserted and so on.
- Q:My hubby just passed his crane test yesterday, and I was wondering how much they pay? He was told to ask for 50k a year..that includes crane time where he works. Can we really ask that? He sets trusses for a big lumber company in Missoula Mt. Any help would be great.
- The little that I do know is that it's one of the most dangerous jobs in the construction field including working around them...so it easily pays that much...
- Q:In Stephen Crane's novel The Red Badge of Courage, why is the war itself not even named?
- There are references in the book to events during the Civil War. In addition, the time of publication by this American author left no doubt in any American's mind which war it referred to. The Spanish American war happened after publication and the primary war on everyone's minds was still the Civil War.
- Q:What does a track type tower crane look like? In that case, use?
- With a trolley, it can move in a straight lineSuitable for short range movement
- Q:i have 5 tower cranes outside my window at different construction sites and they all position their cranes the same direction at the end of the day. is there a reason for this.
- It might be that specific company or something. I'm on the Las Vegas strip right now, and there are dozens of cranes pointed every which way.
- Q:A Korean kid at my school made me one in a new kid meeting. Sadly, he made it with my hall pass that needs to be signed with the teacher that organized it. But when she had to sign it she ripped it up and he won't make me another one! How can i make one myself?
- I was going to do that once when I was about eleven... I got to like 156 and then stopped. Too many, and I had other things to do. I'd like to do it again though, maybe see if it's real or not this time... even if it's not, it would be pretty awesome to have that many cranes. I'm not sure if it will really make your wish come true... you have to make your own wish come true, folding paper can't really do that. But maybe it can help some. It's worth giving it a try.
