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.

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?

Q:for example, if the crane boom lenght is 40 and radius is 11 meter,the how to know about the angle.?
Boy! You really need to get the angle indicator fixed and calibrated! There are ways to estimate, but they are inaccurate and therefore not safe, if you have not got the expierence to do it. Don't use the crane for any load close to your SWL!!! An addition: unless you want to measure your reach, i.e. the distance from the crane pedestool to your load, then you can calculate the angle, but you don't need to anymore as you now know what the distance of your lift is and therefore you can look up the SWL on your chart. Get it fixed.
Q:Can anybody explain how they assemble a tower crane. How long does it take? How?
Yep, they use a smaller crane that sits on the back of a truck and has a telescopic arm, it only takes a few days. There's a lot of construction going on in my city and I've seen them do it.
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:What are the three different types of Cranes?
Gantry okorder.com
Q:What is the dumbest bird in the aviary community? Is it really the Crane?
great question! I would love an aviary that was half open/half closed. I would love the birds to have the option at all times of choosing the protected surroundings (from weather, sounds, other animals, etc) of inside. Just as convenient would I love their ability to be outside in the fenced aviary so as to choose t heir own environment filled with trees, shrubs, plants, fountains but with enough room for me to observe and enjoy their interaction.
Q:What kind of bodies are tower cranes made of?
First, the working mechanism of tower cranesThe working mechanism of tower crane is usually composed of lifting mechanism, luffing mechanism, slewing mechanism, hydraulic jacking mechanism and running mechanism.The hoisting mechanism to realize heavy vertical up and down movement; luffing mechanism and slewing mechanism to achieve weight moving in two horizontal directions; hydraulic lifting mechanism of standard section, increase or decrease, so as to increase or decrease the tower; range of weights can achieve walking mechanism in tower crane and force of arbitrary space motion.
Q:Can you make an origami crane?
I can actually I made a thousand of them one time I learned in 8th grade and it stuck with me.
Q:What type of tower crane does not include tower crane in variable amplitude mode?
Tower crane, tower crane.Tower crane according to its different types, there are the following classification methods.(1) divided by structure type of fixed tower crane by connecting a fixed tower in the foundation or structure, tower crane lifting operation.
Q:how did charles darwin influence stephen cranes writing?
Influenced by Darwin’s Theory of Evolution, Crane believed that people’s actions were determined by environmental factors rather than by conscious choices on their part. He believed also that conflict was the crucible in which human development occurred, and thus was attracted to the violent and seamy aspects of human experience.
Q:I need help on finding the least amount of steps on how to make an oragami crane.?
Start with a square piece of paper. You got that? Fold the paper corner to corner to get a large right triangle, and fold it corner to corner again to get a smaller triangle. You got that ,or did I lose you. Open the paper, and you will see a big X. Never mind the X. We will come back to it. Now fold the paper side to side to get a rectangle, and fold the two SHORT SIDES to the X fold. Open and do the other two by repeating what you just did. Open the paper FLAT. You can now see a 4 pointed star. Along the four sides of the square, push down on the perimeter of the star to make the star come up. Fold down until you have a flat KITE. Make sure you have 2 flaps on each side. What you are looking at now is one wing, and the other one is in the back. The neck and head are inside the wings. Pull them out half way to expose them. Fold one side at the tip to make a head. If you did everything correctly, and hold under the neck with one hand and pull the tail with the other hand, the crane should flap its wing. Write back if you need more help.
