Tower Crane TC7021 Description:

1.CMAX Tower Crane TC7021  is one of the main product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.

2. Tower Crane TC7021 can adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected.

3. Tower Crane TC7021 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.

4.Tower Crane TC7021  has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter,weightlimiter,circumgyrating limiter,and so on. 

5.Tower Crane TC7021  has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operato.

Tower Crane TC7021 FAQ:

1.What is tower crane?

Tower crane is a modern form of balance crane that consist of the same basic parts. Fixed to the ground on a concrete foundation (and sometimes attached to the sides of structures as well), tower cranes often give the best combination of height and lifting capacity and are used in the construction site.

2. What is the meaning of the tower crane’s code?

Take Tower Crane TC7021 for example, the first two letters “TC” means Tower Crane, “70”means jib length is 70 meter, and the last two letter “21” means the tip load is :2.1 ton.

3. What is the principal to quote the right tower crane to the client?

First, we need to know clients’ requirements,for example, max lifting capacity, height, tip load and jib length.. Second, we need to know what the foundation requirement from the client is and Third if there are special needs. CNBM could suggest proposal according to clear data provided by the clients.

Q:How Much Can the Most Powerful Crane Lift?
First, okorder.com/. This means that at 5 m the capacity is 600 tonnes. Double the radius, half the capacity. A crane located at the foot of the pyramid, will be at 115.2 m from the center. At that radius, the crane could only lift 26 tonnes, so this crane could not lift the greatest stones weighing 80 tonnes. Being the boom only 100m it could'nt even reach the center.
Q:what does a paper crane represent/symbolize?
A fun activity to do when you have nothing else to do!
Q:Does anyone which direction (N,S,E,W) a construction worker will leave a crane facing at the end of the day?
I don't think there is a particular direction unless prevailing winds are a factor. Here in Las Vegas, cranes, when idle don't seem to have a pattern. At least from what I have seen.
Q:What is the worlds heavy-est crane lift?
the lift capacity of the Crane is pretty much dictated by the type of crane it is. The largest Gantry / Bridge type is capeable of 1,500 tons.. the largest tower is 100 tons w. a 100meter turning radius. Tracked lattice boom type is 1,600 tons...........(self contained) there's one that will do 4000 tons with modifications including seperate tracks for counterweights
Q:How much more than m of tower crane jib winch point height should be equipped with anemometer
According to the regulations of JGJ196-2010 for the safety and safety of installation, use and disassembly of tower cranes for construction purposes:
Q:How many tons of tower crane QTZ80A lifting?
How many tons to see installation length of arm frame, different lifting amplitude of corresponding weight is not the same.
Q:What are the working mechanisms and safety devices of tower cranes?
About the structure: Tower cranes are all metal structures, so far there is no wood. About institutions: tower crane working mechanisms are: winding lifting mechanism; luffing mechanism; slewing mechanism; cart moving mechanism; lifting mechanism.
Q:what type of crane cam is this?
Crane SSH-310-NC, hydraulic, rough idle, good midrange hp Intake Open-Close BTDC-ABDC 40-90 Exhaust Open-Close BBDC-ATDC 88-42 Degrees Advertised Duration Int. 310 Exh. 310 Degrees Duration @ .050 Cam Lift Int. 236 Exh. 236 Running Clearance Hot Int .000 Exh. .000 Gross Valve Lift Int. .485 Exh. .485 RPM Range min 3800 max 6800 valve float 7000
Q:how do they make those tall cranes so TALL?
piece by piece.
Q:What are the characteristics of a tower crane?
Four, according to the different installation methods of cranes, can be divided into folding transport, self erection of the rapid erection of tower cranes and the need to use the auxiliary machine assembly and disassembly of tower cranes.Can set up their own fast loading crane are small and medium slewing tower crane, mainly used for short duration, low buildings move frequently, the main advantage is to improve work efficiency, save installation cost, save time and labor and material, disadvantage is the complicated structure, large amount of maintenance.A tower crane that needs to be disassembled and assembled by an auxiliary machine is mainly used in middle and high rise buildings, with large working range and large lifting capacity. It is the main type of construction site at present.Five, according to whether the spire structure, can be divided into flat head tower crane and tower tower crane.Tower crane is a new type of tower crane is developed in recent years, its characteristic is the tower cap and the rod part before and after the cancellation in the structure of the original tower crane on the enhanced structural strength of the arm and balance arm, arm and balance arm is directly connected, the utility model has the advantages of:1 、 the whole machine is small in size, easy to install and safe, reduce transportation and storage costs;2, the boom of tolerance and good performance, uniform stress, small damage on the structure and connection part;3, component design can be standardized, modular and interchangeable, reduce equipment idle, improve investment efficiency.It is in the same type of tower crane tower crane head Zhongping slightly higher prices.
