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:Do you find it ironic a crane crashed into Mecca's holiest mosque on 9/11?
Looks like the Karma Bus made a stop in Mecca.
Q:hi, i was just looking for a guide to change a full stock to a crane stock on an m4, (its wired to the back)i dont actually have the gun yet im buying it from a freind, so i havnt had a chance to look at it but the the gg gr16-r4i was wondering if its just a m4 with a stock that is wired to the back, how there is the two long screws that run from the back of the buffer tube to the body, then you just switch it out for a crane stock...anyway anything would be great, thanks

Q:Tower crane 5610 why is it called QTZ63?
QTZ refers to the lifting tower crane, and the 63 is the torque, the unit is tons x meters, generally in accordance with the crane's nominal gravity moment to sub model, which level is close to which model. The latter four numbers, the first two represent larger, the unit is M, and the latter two represent the largest range of maximum lifting weight, the unit is KN
Q:how do you make an electromagnet crane?

Q:What are the safety devices in a tower crane?
(1) lift height limit position limiterFor cranes with variable boom angles, the lifting motion must be stopped immediately when the top of the lifting device rises to the 8OOmm at the lower end of the boom.For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately.(2) lifting moment limiter and maximum lift limiter;When the lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped.If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value.When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.(6) lightning protection and anti electromagnetic wave induction device;For the crane whose hinge height is over 50m, the lightning arrester shall be installed according to the actual situation and the electromagnetic interference shall be taken.(7) tower crane shall install limit torque coupling in order to prevent slewing overload.

Q:are they for camera support
The cranes have the cameras for the panoramic views which are shown throughout the broadcast. There were instances in the past when they also held the camera men.
Q:this wind speed refers to that height of wind speed?
Surface wind speed is greater than 6
Q:The story I'm writing that has Frank Crane in it is here. Is there a better name I could be using for the protagonist?
I agree with the first poster that you are doing something very wrong. Rather than worrying about the name you may want to reconsider the gender.
Q:How do cranes get from one construction site to another without hitting streetlights, wires, car, buildings?
They are disassembled and loaded onto flat bed trailers. The larger the crane the more flat beds.
