Brief Description:


Tower crane 4808 is used to lift building material such as concrete, steel bars vertically and horizonally.

All tower cranes consist of the same basic parts:

1. The base is bolted to a large concrete pad that supports the crane.

2. The base connects to the mast (or tower), which gives the tower crane its height.

3. Attached to the top of the mast is the slewing unit (large ring-gear and motor) that allows the

crane to rotate.

4. Attached to the slewing unit is the jib (or boom), the machinery arm, the counterweights

 and, the Operators cabin

Q:in the title. any books that talk about the physics in a tower crane? or any crane in general? or a similar machine to a crane?
Hi, Well, this is an interesting topic about physics and requires to have a basic knowledge, correct? So here we have some books: - Chopra, K. A. Dynamics of Structures: theory and applications to earthquake engineering. - Bostelman, R., et al. “Toward Next-generation Construction Machine,” Proceeding of American Nuclear Society 9th International Topical Meeting on Robotics and Remote Systems. - Gore, Bryson. Trucks, Tractors, And Cranes. - Grote Antonsson, editors. Handbook of Mechanical Engineering. - Seidel, Michael. Tensile Surface Structures. B-) FL ------------- You cannot teach a man anything; you can only help him discover it in himself.” (Galileo Galilei)
Q:How big is the contactor lifting? How big is the car and how big is the turn?
This is not very good answer, the United States originally used Tianshui 213, and then used the Japanese MITSUBISHI, used Schneider, LG, star power, Eaton.How big is the lift? It depends on the size of the motor you use. 24KW motor, the choice is about 100A. 30KW uses 125-150A, 55KW, and 150-180A;Generally 40A contactor is used for turningCar selection of 25A on it.
Q:I'm talking about one of the ones where the cabin and the worker is high up in the air. You cant exactly remove a part of the bottom of the cranes structure because it would fall on top of you but you cant remove the cabin because its so high up and what can get up that high to remove it except another crane BUT how did that get built ?Thank you.
A tower crane is usually assembled by a telescopic crane of smaller lifting capacity but greater height and in the case of tower cranes that have risen while constructing very tall skyscrapers, a smaller crane (or derrick) will sometimes be lifted to the roof of the completed tower to dismantle the tower crane afterwards. A self-assembling tower crane lifts itself off the ground using jacks, allowing the next section of the tower to be inserted at ground level.
Q:3years after I quit a job,I am once again looking toward the same field it's just that in my old job they helped me get a crane license when I left the job they kept my certification .How can i get that info without asking my old work for it,or would i have to take the course over?
There is actually no such thing as a crane operators licence - you should tell your new employer that you had undertaken a course in your previous employment and were authorised by them to operate their cranes. The new employer will most likely then send you on another course and issue you with their operators authorisation. The authorisation from your old employer is not transferable to the new one so not having the certificate is not a major problem. It is however good practice for employees to receive a copy of the certificate for their own records.
Q:Flocks of cranes shout'. Is it right to use the word'shout' here?
No, it's not. First, the collective noun for cranes—its term of venery—is either herd or sedge, not flock. Second, the sound a crane makes is a whoop, or when not a whoop but a rattling sound, it is a bulge, not a shout.
Q:anyone can tell me the common steel tube material using for crane boom, both main chord and lattice boom. thanks !
Most aerial cranes (Erickson Skycrane) are used for tasks such as remote location work or expedious work. It takes awhile to erect a crane for one air conditioner unit to be replaced on top of a 5 story building or to replace a cable on a wire bridge. They are also widely used for fire supression.
Q:who invented them and why do people make them?
in Japanese folklore if you fold a 1000 origami cranes you get are granted a wish, usually concerning health/long life. The peace part comes from the story of Sadako Sasaki a victim of the Hiroshima atomic
Q:In the U.S. please and tell me where and how you got the number.Thanks!!!
There are so many overhead cranes in operation today in the US and around the world. They could be numbering in tens of thousands in industries and other operations. An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of a crane, travels along the bridge. If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane (USA, ASME B30 series) or a goliath crane (UK, BS 466). Unlike mobile or construction cranes, overhead cranes are typically used for either manufacturing or maintenance applications, where efficiency or downtime are critical factors. Have a pleasant day.
Q:my overhead crane refuse to work transvesely
Limit switch replacement requires adjustment of the cranes travel limits. The limits are imposed by the manufacturer for the application. This service is normally factory authorized only.
Q:It got me thinking.
I have not seen the movie, but I think I saw what you're talking about on a preview. I would think that the safeties involved in the control system for a crane would make it highly unlikely to happen. There is no absolute assurance, only probabilities or likelihoods. You just hope that you have enough failsafes in the system so if one part of the system fails, the others will take over, or shut the whole thing down properly.
