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.

Engineers have more than 20 years' experience in tower crane, ready to solve any of your problems.
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: 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:Can anyone give me a very accurate slow step-by-step video of how to make the prison break crane perfectly?Its hard to follow the directions on a diagram online so I need a good video.
- you okorder and there ou can search prison break crane!!!
- Q:I just made origami cranes and want to hang them up, each by themselves with just a peice of string....how should i go about doing this? how is it usually done?
- TAke a needle threaded with a long piece of black thread, and make a small knot at end of long thread. Push the needle thru the middle of the crane's back and pull the thread all the way thru the hole till the knot catches. pull the needle off the loose end of the thread and make another knot on that end. take a push pin or thumb tack and push the pin thru the knot, then push the pin or tack into the ceiling. FYI, tape never works - I have tried. The black thread lets them flutter a bit, and is invisible most of the time. p.s. ask your parents if you can hang stuff from the ceiling first. they may not want you to do that since it will leave holes in the ceiling when you take them down.
- Q:the lifting capacity of a hydraulic crane is based on two primary design factors what are they?
- The potential lifting force of a hydraulic crane is primarily based on the diameter of the piston and on the pressure of the oil. Everything else is subservient, but necessary.
- Q:How would you argue that Helga Crane does change in Quicksand by Nella Larsen?
- Helga Crane
- Q:Climbing process of an internal climbing tower crane
- Climbing tower crane, usually installed in the elevator shaft building or ad hoc Bay, also can be installed in the cylinder structure, by means of a climbing mechanism increases with the structure increases, generally every building 3~8m, crane climbing a tower, its height is only 20m left and right, lifting height with construction height and.
- Q:How the cranes can stand without any tipping with huge counter weights on its back? If there is no suspended load also the crane is is still stable with huge counter weights on its back. How it can possible? Why crane is not offballencing while we adding extra counter weights on it without any suspended load?
- 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.
- Q:the question is :Two cranes can unload a ship together in 15 hours. The faster crane takes 16 hours less than the slower crane, if each were to unload the same ship alone. How long doesi t take for each crane to unload this ship? I done most of the math but i am stuck with this last part .15+- radical 1185/2
- No. of hours for the slower to unload alone—x: 1/x + 1/(x - 16) = 1/15 (x - 16 + x)/(x? - 16x) = 1/15 15(2x - 16) = x? - 16x 30x - 240 = x? - 16x x? - 46x = - 240 x? - 23x = - 240 + (- 23)? x? - 23x = - 240 + 529 (x - 23)? = 289 x - 23 = 17 x = 40 No. of hours for the faster to unload alone: = 40 - 16 = 24 Answer: slower crane, 40 hrs; faster crane, 24 hrs Check: = 15(1/40 + 1/24) = 15([3 + 5]/120) = 15(8/120) = 15(1/15) = 15/15 or 1
- Q:how to pass a crane practical test?
- Practice make perfect.
- Q:my overhead crane refuse to work transvesely
- Limit switch replacement requires adjustment of the cranes travel limits. The limits are imposed by the manufacturer for the application. This service is normally factory authorized only.
- Q:Or what style? ?
- i aint trained in kungfu but i have studied it... im a karate practitioner and abit of a boxer. one day i was bored and looking up martial arts then i came across kungfu... it was very interesting looking it up. Theres over 300 styles of kungfu. some styles of kungfu represent a animal. For example... you got crane kungfu... if you know what a crane is, its a type of bird... strong on its legs, well balanced... goes with the flow, elegent. Crane kungfu practitioners have strong perfect balance... just like the crane. You got snake kungfu... just like a snake, it looks at there prey and attacks very accurutly... the speed of the snake bite is so fast, you might not even see it coming. So with snake kungfu practitioners... they are swift like a snake, smooth... Theres tiger kungfu... just like a tiger... vicious, focused... they attack there prey, strong... hard. Theres monkey kungfu... not sure about that one. but thats some styles i know... theres other styles like jeet kun do (the way of the intersepting fist)... drunken boxing ect... this is some of what i know... oh yh theres anouther style called the praying mantis... looks very good. so inconclusion... most of the animal styles of kungfu represent the animal in a certain way... which makes kungfu spark out for me. hoped this helped :)
