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 serice you could provide?

A: Providing timely delivery, standby engineers are ready to slove any of your problem

    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: don't its wheel provide the same amount of friction?
the capacity of a travelling crane relates to its resistance to tipping, and is dependent upon wheelbase, which can be extended by use of the outriggers, and counterweight (the big boxy thing at the back of the crane). Every lift requires a firm and stable platform which is what the outriggers provide. For every lift (weight) and reach (how far from the slew point), there is a limiting capacity factor. This is required to be posted within the operator's cab. The actual load lifted may be monitored by a load cell on a running rope (or other location), and through a computer control, limit the actual capacity of the crane.
Q: I am NCCCO certified here in the US and would like to know how to be able to work as an operator in France.
Me too(NCCCO) how long for you? What do you run? I run a Terrex/demag a/c 140, Grove TMS 870, and a little national 40 ton. Anyway, sorry I don't have an answer but the other day just for kicks I was looking around to see what's going on and searching crane operator+job and there's a huge worldwide company, slips my mind but they kept coming up all over hiring operators all over the world. Give that a try, if I was single I'd be going everywhere, and getting PAID to do it but my wife and kids mean too much to be away. Try this.... search crane service+france email some crane outfits and ask around, it can't hurt.
Q: I'm researchign for this demonstration speech on origami and uncovered a legen that says in the Japenese custom if you fold 1000paper cranes you are granted a wish. Just wondering, has anyoen ever tried this? and the outcome?I'm goign to do it this weekend!
my daughter's art club did this for a hospital not to long ago...they made 1300 paper cranes and hung them from the ceiling in one of the hospital wings. I don't know about being granted one wish, but it made the patients happy and smile no matter how sick they were. I've heard the paper crane was some how connected with leukemia, so she made one for a friend of mine's son (he is only 7 and has battled this disease for 2 years) and it made him happy to know that someone who doesn't know him would make something like that for him.
Q: In Scottsdale AZ I have never noticed them before this year. They are on the walls all around our doors.
Crane FLIES not cranes. The winter crane fly has an abundant hatch--well, during early spring or late winter. In this they are just everywhere--this species just does this sort of thing. Typically crane flies are a rather rare sight, such as during the summer months, usually of an entirely different species. There's really not much to explain their abundance.
Q: ok, so if chad is a crane then why doesnt he stay in the mansion? he is a crane right?
Chad is a Crane, for those who are saying that he isn't. He is Alister's son with Eve's adopted sister Liz (Eve and Liz aren't blood related). He was living at the studio for the longest and I guess he got adjusted to it. I would think Chad doesn't want to be involved in what goes on in the mansion. Fox is a Crane too, and he doesn't live in the mansion. He lives with Kay at Tabitha's house. Sheridan doesn't live in the mansion, but yes, she lives on the premises in the cottage.
Q: Where are cranes mostly found in the world?
East Asia has the most species of cranes in the world, 8 (Chinese cranes) followed by Africa with 5.
Q: How do you calculate ground bearing pressure for cranes?
Crane Ground Bearing Pressure Calculator
Q: I need a answers to these questions for a school project.These questions are:-How and when did it occur when the Siberian White Crane got threatened and critically endangered?What are the causes of this environmental issue?What are the effects of this environmental issue?What has or is being done to prevent such and environmental issue occurring again?Thanks, it will really help me with my final mark.
Check okorder . There is some very interesting information at this site.
Q: i really need help
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.
