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:Is boom truck a crane truck? Are they the same or two different kind of truck?
A 'boom' is attached to a flat-bed truck and is used to unload a heavy delivery (usually building supplies and materials) to a specific location. A 'crane' is similar except that it doesn't unload things. It is attached to a truck and is used for moving heavy objects and materials from one place on another on the same property.
Q:Does anyone know where I can order Sugar Crane to grow?
Crane? anyway,, if your store has those little pieces you can buy to eat? or if you know someone with canes,, you strip off the hard outer covering,, this has the seed buds,, plant these in 3 inches of soil and wait,, cane is slow growing!! if you google sugar cane growing or go to wikipedia you will find plenty of info google buy sugar cane seeds you will find sites to order!!
Q:1000 japenese paper cranes ?
you make your wish once your done cause you only get the wish if you have 1000 cranes right so saying your wish when you only have 6 won't do anything. it can come true the next day till the next year or ten years it not something definite. I've never made 1000 but I think I will.

Not sure if there is a video but if you check out Analysis of Shaolin Chin Na by Dr. Yang Jwing-Ming you might find something.
Q:How many meters is the tower crane installed on the edge of the deep foundation pit?
Tower crane foundation, if set up in the foundation pit, the foundation is to pile other, general tower crane is to support the wall.Therefore, how far away from the foundation pit is determined by the distance from the retaining wall.According to the industry standard "technical specification for concrete foundation of tower crane tower crane foundation installation" (JGJ/T187-2009), the installation of tower crane foundation concrete should reach more than 80% of design strength, the tower crane foundation concrete design strength should reach 100%.
Q:How do you build a crane? (it is for a school project)?
Do you need to build it so it can pick stuff up, cause thats gonna require, magnets and alot of other stuff, that I don't feel like talking about, bye:(
Q:Equipment safety of tower crane
The boom of a tower crane is divided into two types: horizontal and compressed arms. When the movable arm is horizontal, the carrier car runs along the horizontal arm with variable amplitude and amplitude, and the movable arm is longer, but the boom has a larger deadweight. The arm for the strut type when the tractor boom luffing mechanism pitch amplitude, amplitude motion than horizontal smooth, but its relatively small weight.The weight of a tower crane varies with its amplitude. The product of the weight and the amplitude is called the load torque, which is the main technical parameter of the crane. Through the rotary mechanism and slewing tower crane, lifting height, rotation and walking the inertial mass, so it needs to have good control performance, especially the lifting mechanism can fast, slow, heavy and light load installation fretting. In addition to the general use of resistance speed regulation, but also often use eddy current brake, FM, pole change, SCR and mechanical and electrical joint speed regulation. When the crane in the layout to drawing, especially in real estate development area, residential buildings, such as tower crane, but also to consider the safety distance of adjacent tower crane, two in horizontal and vertical direction to ensure the safe distance of not less than 2m, the adjacent tower crane tower crane and interference can not occur. Try to ensure that the tower crane in the wind is too large to be free of rotation. The safe distance between the rear arm of tower crane and adjacent buildings shall be no less than 50cm. The safe distance between tower crane and power line meets the requirement.
Q:Are steam cranes still used to clear train derailments?
No, they don't. They have to use road cranes - think of the accident at Grayrigg some while back. They had terrible trouble clearing the line as heavy lifting equipment had to be brought quite a distance over muddy fields. I seem to remember special temporary roads had to be laid. Similarly with the freight accident in Scotland a few weeks back, roads were closed, again whilst wreckage was cleared.
