2. Tower Crane TC6520  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 TC6520 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 TC6520  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 TC6520  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 TC6520 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 TC6520 for example, the first two letters “TC” means Tower Crane, “65”means jib length is 65meter, and the last two letter “20” means the tip load is :2 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:Why are there extra placards attached to the tower crane tower?
Because the span of the base is short, the tower is efficient, and the billboard is easy to cause the tower to overturn or bend.
Q:How to explain and classify the types of tower cranes? What do QTZ80 and Q5510 mean?
This is only the tower crane in different periods of different naming:QTZ---- is the general saying in 80s of last century, Q means steel material (usually Q235), T is tower crane (mostly tower top type), Z indicates heightening method is self lifting,PT------ is the naming method in recent years.
Q:What is the torque limiter of the tower crane A: the lift is stopped when the lifting torque is exceeded. B: over gravity
The torque limiter acts as follows: (a)In lifting process, when the weight of the lifting object moves ahead of the trolley when the lever force exceeds the moment limiter, the hook rises, the motor and the trolley forward motor are stopped at the same time, and the utility model has the safety function.
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:How to install the jack up tower crane 30How to install the jack up tower crane?
It is required from the upper plus height, then the crane through the motor (hydraulic is not I don't know if not carefully studied to estimate almost) slowly up, because the installation of crane is a separate Union, only the crane is fixed on the top, and is connected to the lower die width ratio some long, above there are for the installation of people stay small table, but also it can open from the opening above the dead ground fill and then fix it by bolt, and then put the live up to OK
Q:Examples of filling and acceptance forms for tower cranes and examples of filling in.
3 no or no inspection items are completed". In the absence of such or part of the sub - item, it shall be drawn on its serial number".
Q:How to improve the stability of tower crane
The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3 times of the same structure light steel wire rope (laboratory comparable conditions), not easy to wear and corrosion is not easy to cause the service life of wire rope large amplitude extension. Manganese phosphating is wear resistant phosphating, which can solve the wear problem in the use of wire rope and improve the corrosion resistance. It is for reference only
Q:In the case of tower crane operation, the operation should be stopped
In case of six or more gales, heavy rain, heavy fog, heavy snow or tower crane, you should stop working
Q:Do self lifting tower cranes allow a small swing of the boom in jacking operation?
The upper working structure of the attached tower crane is connected with the jacking sleeve frame, and a jack jack is mounted on the top lifting jacket frame. The upper crossbeam of the jack is connected with the jacking frame, and the lower cross beam is provided with a movable claw, and the lower supporting point can fall on the step of the standard section of the tower body. During lifting, first trim jib and balance arm, unlock the top are connected with a lifting sleeve frame with the standard section, start lifting system, lifting jack will superstructure.
Q:What does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
