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:Were the anti-gravity machines used to build the pyramids levers, winches and cranes?
Levers winches and cranes all use a counter balance. Its weight that helps move weight in different ways. There is no such thing as an anti-gravity machine.
Q:Im hearing this like every day theres more going down..why is it happening? A terrorist plot perhaps? I say we send some troops to stand guard and prevent another tragedy!
These are dangerous peices of equipment, they endure high stress and are at times pushed to the physical limits. I have on occassion worked with and under them and always had a lot of respect and always felt safer when away from them. Construction cranes in particular are more dangerous because they are forever changing in height,position, amount and type of load. Cranes in permanent installations are ususlly carrying same or similar loads. Construction sites are hazardous due to many factors but just about everything on site gets handled by the crane at one time or another. Inspection,inspection, and re-inspection with concurrent correction/adjustment are the only preventative measure availble beside the assurance of competency of the operator. There are plenty of laws about them already but this is not to say new ones might be justified as new hazards become apparent. Most terrorists are too dumb or lazy to get involved with cranes--why bother when so many easy targets are out there !!!!!!!!
Q:the lenght of beam is 4.5mmaterial of beam is ASTM Gr60
difficult question
Q:how do they get counter-weights onto high cranes?
The top section of a tower crane, including the cab, boom, and counterbalance, is erected on the crane's base, using a portable crane. After that, there is a mechanism on the tower crane that jacks up the top and allows another tower section to be inserted under it to increase the crane's height.
Q:Hi guys, I am doing a project for school on blue cranes, and i can't find much on what their diet is like? Does anyone know?
Blue cranes? You mean great blue heron. They eat fish, frogs, snakes, anything smallish that lives in shallow waters.
Q:There is no CAD map attached to embedded parts of tower crane?
What size do you want?. Each model is different. For example, the 5010 tower bolt embedded needs 24.
Q:Two cranes can unload a ship together in 8 hours. The faster crane takes 12 hours less than the slower crane, if each were to unload the same ship alone. How long does it take for each crane to unload this ship?
If an answer of -4 hours is expected, pl. excuse. The practical difficulties of the faster cranes are constraints - the loading to / unloading from any crane is tricky, time consuming are with practical problems. The ship. yard where it is angered, the type of the cargo also decide the swiftness of unloading ; so it is not simple ratio !
Q:What are the parts of a tower crane? What are their main functions?
The tower crane is mainly composed of a tower body, door frame, tower, tower cap, boom, arm and other metal structure and balance hoisting, luffing, slewing mechanism operation, composition and electrical system and safety device etc.!
Q:Tower cranes should stop working when the wind speed is greater than the magnitude.
Tower crane work is strictly prohibited at grade 4 or above
Q:how to pass a crane practical test?
you get a crane and operate it...not hard if you know how....
