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.

    Providing all-embraced warranty of products quality, worksite installation guidance

    Providing ample spare parts and training of operation and maintenance

    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: How would the environment, habitat, or ecosystem be affected if whooping cranes were extinct?
There would be no more whooping cranes for one thing. There would be a gap in the food chain and whet ever feeds off of them could go extinct if they have to have them. What ever the cranes ate might over breed if not held in check and if they are harmful might cause an epidemic that could upset the balance of power in the ecosystem of Florida. All this is speculation but anytime any species disappears it is gone forever and anything can happen.
Q: need a 5 ton jib crane design with drawing please help, boom 12ft hub 16ft?
Hello, okorder /
Q: its dead im so scared if thes so called flys i tired to kill it but wen ever i get some thing to kill it its hideing
Crane flies, also known as mosquito eaters or mosquito hawks, are harmless. There is no reason to fear them. They do not bite or feed on anything and only live a short time, maybe 24 to 48 hours. I have them in my house quite frequently during March and April. They fly really slowly and don't try to fly away if you want to smack it with a flyswatter. They are big and ugly but that's about it. They seem to be more active at night and are attracted to light, kind of like moths. Maybe you could lure yours out of your room by leaving a light in the hall and other rooms dark.
Q: It's better if the explanation is not complicated.TQ
Hello, 1. Modularity: You can build ships (larger ships) in modular sections and have the crane lift these modular sections and put them into place for final assembly. This is one major advantage that was not available back in the day
Q: Is the working load of a crane the maximum weight it is able to lift?
generally the safe working load (SWL) is the max weight a crane can lift in regular operation . but for testing purpose the crane may be loaded more (1.5 times SWL or 2.00 times swl) further it depends on application of the crane. The reason being if you test the crane for higher values, it means it is safe to use within the SWL But the higher value must not cross beyond structure design load
Q: How did Romans make columns in roman times Without cranes?
They simply lay the stone down, chiseled out the column, then stood it up via an A frame, however the Romans did have cranes, (not the massive things of today) but mobile wooden ones with counter weights at the back that operated on a system of pulleys (they even had cranes that operated on water)
Q: how much does a crane operator make ?
don't know
Q: Form the movie Dreamer, daughter of Ben Crane
It was Dakota Fanning that played Cale Crane, daughter of Ben Crane in the film Dreamer: Inspired by a True Story. She's a good little actress. I love to watch her films.
Q: Type and specification of tower crane,
Big Han tower QTZ63 series mainly produces 5010, 5013 and 55105010 arm length 50 meters, arm tip bearing 1 tons, the basic height of 30 meters, standard section specifications: 16*2.5, 5013 arm long 50 meters, arm tip bearing 1.3 tons, basic
Q: Are sandhill cranes edible?
Most living creatures are edible. That being said, it doesn't mean that A) It will taste good or B) you will like it. However, there is an old saying that says, Just because you can doesn't mean you should. Now, if a person needed to eat one in order to survive a dire situation that's one thing. However, just to kill it and eat it out of curiosity is another thing. My suggestion...eat chicken (haha) besides most mystery meat is always said that it tastes like chicken. Another thing is that if you choose to mess around with wild birds, there's no guarantee that they don't have diseases like Avian bird flu. Farm raised animals at least get tested. Also, are sandhill cranes considered endangered for that matter? Just stuff to think about. You might want to talk to a Game Warden.
