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: What are the "2 magnification" and "4 magnification" mentioned in the lifting characteristics table of tower cranes?
Popular saying: "car to hook this section of vertical distance, you see 4 wire rope is 4 magnification, you see 2 wire rope is 2 magnification.".
Q: Describe how a bottleneck event reduces genetic diversity in a population, and specifically how this has affected the current population of whooping cranes in the U.S
Well, a bottleneck reduces the number of organisms in a population or species down to a much smaller number than previously existed. In the case of the whooping crane, the species underwent a bottlenck event (although what it is I'm not sure), leaving us with less than 12 individual birds. The more widely accepted number of 6-8 birds has given rise to the several hundred whooping cranes alive today. Since only half a dozen sets of genes were used to create the several hundred, there is not much genetic variability.
Q: i have an echo-1 m8a4 cqb it has a crane stock that fits a 9.6 1500mah battery but it wont fit a 2000mah so i want to switch to a full stock but im haveing trouble figuring out how to switch them. does anyone own this gun and know how to do it?
Ok, I can help. The first step is to take the crane stock off. To do so, extend the stock fully. Then, take the tab you use to extend it, and instead of pushing up to extend it, pull it down and slide the stock off. It make take some force. Be careful of any wires and that you don't break them! Next: take the buffer tube out. Take a long phillips head screw driver and stick it down the shaft. Remove the screw. The whole tube should come out. Don't lose the screw! Next: Install your stock. Next: Screw the screw back in to secure the stock. Done! Make sure the wires are still ok and that they are not pinched!
Q: I have recently mounted a Meiller MK 40 R / 2 crane on my truck and I wonder if my truck's hydraulic pump can support it without problems. I have a Mercedes-Benz 813 truck of 1987 and the crane is more or less the same years by the way. Should I change my truck's pump?

Q: What is the difference between a crane and a crane in a tower crane?
There are the following differences between crane crane and Signal Engineer in tower crane:1, lifting signals refers to those who signal flags in the works.2, the engineer referred to the engineer who tied the rope in the works.
Q: I know that an ancient Japanese legend promises that anyone who folds a thousand origami cranes will be granted a wish by a crane, such as long life or recovery from illness or injury. This summation, or something like it comes up in every search I do for the legend. Is there a full story that goes with the original legend? If so I would very much like to read it. Wikipedia doesn't have it. Also, while Sadako's story is very touching, it is not the one I'm looking for.
It okorder / I'll keep looking and see if I can find out an origin and add a bit more later.
Q: What are the impacts of construction cranes on the human society?
construction cranes enabled the building of multiple story buildings which fostered urbanism. It changed the village oriented way of life in America, for good and bad. We became more boadly oriented in our business ventures which increased the stanting of the U.S. in world affairs, but it decreased the degree of brotherhood people felt for each other as they left their roots and dwelt amongst relative strangers.
Q: What role does the tower crane torque limiter play?
The overload protection of tower crane is protected by two equipment, lifting load limiter and torque limiter. The latter generally in the big arm root 4-5 meters to the front of the large arm, overloading (Chao Liju) work, it is more important, basically, the scope of work is torque limiter plays a protective role. While the former is the weight limiter function in the arm root within 4-5 meters, because the tower crane is a jib type crane, each allowing weight lifting position corresponding to the different (CAB load curve). For example, such as 63KN.M, the big arm root 2 meters lifting, the theory is 23 tons, while the torque limiter is not over, but in fact, the tower crane at early crouched down, so the weight limiter in this work.
Q: heres a picture of one
they are put up section by section with another crane
Q: Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?
Use trigonometry, it's a triangle of forces.
