Main Features of Tower Crane
1) This kind of crane adopts standard section hydraulic lifting and connecting.The max. height can reach 180m with wall tie ins.
2) 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.
3)The range-change structure drives the trolley moving on the horizontal crang jib, 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. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..
5)The cranehas scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.

FAQ about Tower Crane
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 about our tower crane 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: Preferable short poems or phrases in Chinese.
- this one is about cranes We thought they were gulls at first, while they were distant- The two cranes flying out of a natural morning, They circled twice about our house and sank, Their long legs drooping, down over the wood. We saw their wings flash white, Frayed at the black tip, And heard their harsh cry, like a rusty screw.
- 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: I don't know what the difference is. :(
- an egret is any of several herons and several of which develop milky white plumes during the breeding season,some herons are called egrets. Cranes are a family of large, long-legged and long-necked birds Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Cranes’ necks are a shorter than those of heron.Herons curve their necks into an “S” shape and when they are flying they pull them totally back, while cranes necks’ stick straight out. Cranes also have shorter beaks than herons.
- Q: What are the lifting moment requirements for tower cranes?
- 2 tower cranes (tower crane) referred to as tower cranes, also known as tower cranes, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..Has a good safety device
- Q: Please give a scripted answer. Funniest Denny Crane comment and action gets the 10 points
- Did you just fart?
- Q: I just watched hunger games, and in the end Secana Crane was locked in a room with nightlocks, but why did they do that to him? what did he do to get killed?
- The Capitol is a government that rules through absolute control. They're keeping the different areas under control through force, and everybody is too afraid of being killed to stand up to them. The Hunger Games are there to make people afraid of revolting and to give them some hope of one day becoming famous. Crane got killed because he allowed Katniss and Peeta to beat the game. The point of the Hunger Games is that there can only be one victor, but Katniss let them both live. By doing that, she showed that the Capitol couldn't control everyone absolutely, and they could beat the Capitol if they tried. Crane got killed because he let that happen. It also drives home to the reader how brutal Snow can be, and how willing to throw away a life he is.
- Q: LCS , MCS , HCS?
- Lots of good replies already for this question
- Q: I'm not scared of spiders anymore. If I see one than I can kill it easily, but when I see a daddy long legs crane fly, I freak out! Those things are hugeeee. I could never kill one without being freaked out to death. I heard that they don't even bite, but I'm still scared. There's one in my living room and I ran out. So I planned on staying in my room the whole day and just hope it doesn't show up in the bathroom tomorrow morning when I shower! I'm 14 btw?
- This is a selective entomophobia. Basically, you don't fear many insects or spiders, but specific ones trigger your anxiety. Your problem is not the bugs or spiders,(they are harmless) but your fear. This is something 'you' nurture by dwelling on this fear when you see one of these particular critters. I'm glad to hear you no longer fear spiders. you will see the same when you overcome your selective fear. You may even come to realize that the spiders and insects you do fear,are totally harmless, and you may reach a point where you can just ignore these. True, the crane fly is totally harmless and do not bite, sting, or inflict any form of hazard to humans. They can be a nuisance buzzing around your face,as they can be persistent. Adolescent years seem to be when phobias are the most prevalent, but also the easiest time to overcome fears. If you can learn to control your fear, rather than let it control you, you will overcome this. you also need to refrain from dwelling on your fear,as this will only make it worse. Last year, one of my favorite pass times was sitting on the porch watching the sunset. a little orb weaver would come from behind the light and spin her fancy web. Often, I would catch a crane fly that was bothering me and toss it into her web.
- Q: More than meters of tower cranes must be equipped with red barrier lights at the top
- To see the land of tower crane or floating crane... Basically,
- Q: this is a little of a random question but why do you think that we should save the crested cranes of uganda? and what do you know about the crested cranes???
- Why shouldn't we? Where do we draw the line when we're responsible for species after species going extinct. Granted, you shouldn't be expected to physically rebuild their habitat yourself if your not up to it; but a small change here or there isn't to much to ask to help save the world, is it?
