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: How should I go about stringing paper Cranes together??I alreadly know how to make them, its just that I have no clue how to put them together
Depends how you want to string them... but use thread and a needle. If you want to string them vertically, put the needle through the body of the paper crane... I not sure about horizontally. Too keep them in place, place knots below the body of the crane. I hope this helps, but I hope another more experienced person answers this :P
Q: A crane operator must ensure that the load is within load chart ratings for _________ and the __________ of the crane.A. Boom length; CenterpointB. Boom length; Load RadiusC. Center Point, Load RadiusD. Center of Gravity; Load Radius
B. The load radius is the horizontal distance from the center of rotation of the crane to the center of gravity of the load being lifted. The load radius is a critical consideration when determining what size crane is required for most lifts. There is generally a chart that tells what that machine will lift at any boom length,
Q: have you noticed that there has been an exceptionaly high volume of cranes falling over in the U.S.A. this year? 2 cranes went down this week, one in Texas killing a man. seems like there has alot of this lately, what the hell is going on with the cranes? ever night i turn on the news its like a deadly crane accident took place today . thanks.
Accident Reports Received for year 2007: 347 Deaths for 2007: 176 Accident Reports Received for year 2006: 314 Deaths for 2006: 109 Accident Reports Received for year 2005: 231 Deaths for 2005: 127 Accident Reports Received for year 2004: 287 Deaths for 2004: 142 Accident Reports Received for year 2003: 269 Deaths for 2003: 138 Accident Reports Received for year 2002: 171 Deaths for 2002: 96 Accident Reports Received for year 2001: 161 Deaths for 2001: 107 Accident Reports Received for year 2000: 184 Deaths for 2000: 74 (It gets really scary when you look at the increase of deaths in just a few short years.)
Q: i live in cali and these things are really starting to piss me off!!!!!!! I never noticed any before ( when i lived in colorado) but it seems lately that they are all over!!!! every time i open my damn door AT LEAST 5 of them come in! THERE SO GROSS with there big hanging legs! EWWWWW! Anyways, when will they go away and what do i do to keep them from getting in my house?
The crane fly season only last for a month or so. There are years when they can reach almost plague proportions but within another 2-3 years their numbers should return to normal.. They can cause some damage to farm crops but the good news is that they are harmless to us.
Q: If so, would you mind finding me a site that will teach me how to either with a good video or an easy-to-follow explanation because i tried many sites and i just cannot understand clearly enough. I get so far and then i can't tell what is happening in a step, and i can't do it.If you wouldn't mind to find me a site that you know will help, since you can make them, it would be greatly appreciated.Thanks.

Q: What is the minimum radius of a tower crane?
Luffing jib crane luffing mechanism to control the lifting radius, which is lifting and landing boom.At the minimum radius, the boom is angled to the vertical.
Q: I was given a CCRadio and I have no idea what it is or what it does.The guy that gave it to me says it's an Awesome DXing radio (whatever that means). The display doesn't work but other than that the radio works fine and pulls in alot of stations the previous owner said. Can anyone help me understand what a CCRadio is and what it does? Thanks to all that contribute.
C Crane Company sells shortwave receivers. You can use it to listen to shortwave broadcasts, marine weather, NIST time signals, foreign broadcasts, clandestine broadcasts.
Q: I was half way through this book and had to stop reading it because school got in the way. I'm back to reading it and I got to the part where Katniss made a noose and tied it around a dummy and showed it to the Gamemakers. And she wrote 'Seneca Crane'. I don't remember who that was. If it was even a person, I guess it was. But can you just explain who or what 'Seneca Crane' is and why Katniss would do that? Thanks.
I think it's one of the gamemakers, but that's just a guess.
Q: in design of steel structures as per asce2005 or ibc2006 ,what load combinations are to be considered when crane loads and seismic loads are present?
Asd Load Combinations
Q: Since now everyone will know what's coming when you get in the crane kick position, and the element of surprise is gone, has the crane kick become an extinct move? Do martial arts experts not like the Karate Kid for ruining the crane kick in the way magicians don't like other magicians who reveal their secrets?
yeah, because, Okinowan Crane had an unbeatable technique (as Miyagi described it). Anyone with a shred of common sense can see what was coming.
