Product Description:

Characteristics of Tower Crane

1)This tower crane is one of the key 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) This kind of crane 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; The max. attached height can reach 180m.

3) It 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.

The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.

4) The crane has complete set 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, weight limiter, circumgyrating limiter, etc.

5)The machine 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 operator.

Q:How to build a basic electric magnetic crane.?
To push an object away, you need equipment that is low to the ground when it applies the force. Bulldozers are designed to push objects. Electromagentic cranes are designed to deal with vertical forces, so they are used to lift and drop metal objects. They use electricity to flow through coils wrapped around a metal core to generate a strong magnetic field. Trying to use them to push things could cause a crane to tip over since they are not designed to deal with horizontal forces. Even if you could get the electromagnet wired to repel metal objects, when you bring the electromagnet near the object, it would repel away in an unwieldy manner because of friction and interference with the ground. And trying to direct a large electromagnet at the end of a long chain would be difficult.
Q:On the wing chun T-shirts they got i print of a crane and a snake what do they mean and the yin and yang?
Wing Chun was developed from the five Shaolin animal styles, tiger, snake, crane, panther and monkey. The popular (incorrect) belief is that the style contains more of the crane and snake styles than of the other animal styles, hence why it is sometimes referred to as a crane and snake style. The crane, in the Shaolin system, is evasive, protective and gentle, using flowing techniques that redirect the attacker's energy, rather than fighting strength with strength. The snake is a very fast, straightforward style, protecting the centreline and attacking along straight lines with quick thrusting finger attacks. These two principals are, admittedly, very prominent in Wing Chun's use of the centre and central lines, the use of chisao (feeling) in techniques, and the use of straight, stretching techniques like the finger-strikes. (The bit that some people don't realise is that Wing Chun contains elements of all 5 styles, including tiger, panther and monkey, as well as some elements from non-Shaolin styles, such as elements of tai chi, shuai jiao (Chinese wrestling), dim mak (pressure point striking), chin na (joint manipulation) and others.) The yin-yang symbol comes from Taoism, and represents the equality of opposites, such as night and day, sun and moon, hard and gentle, forward and backward. Wing Chun, and indeed all Chinese martial arts, contain Taoist philosophies and strategies that can be explained by the use of this symbol.
Q:Meaning of Japanese origami crane family kamon?

Q:how long do i have to work as a yardhand in oilfeild to become a crane operator?
You need to get licensed or certified to operate the crane. make sure you are qualified before you start complaining about not getting more challenging work. The world needs ditch diggers to so get back to work.
Q:What is the allowable range of vertical deviation for tower cranes?
Independent height 4/1000, attachment height 2/1000 under top wall!
Q:can someone please explain how a crane is lifted from floor to floor while building a High rise?
It's lifted in sections I believe. Once they're at their intended vertical height they then start to construct horizontally. Bit like big boys Mechano (not sure if I spelled that correctly).
Q:can u have a small dog w/u when u are operating a crane?
I can't imagine any employer allowing that condition to exist. A crane operator's attention must be on the job at all times. If the dog were to do something unexpected at a critical time, the operator may be distracted and lose control of the load.
Q:Is there anything similar to the traditon where you fold 1000 origami cranes and you get a wish?
The 1000 paper cranes thing really only became popular after the 2nd world war- a girl in Japan was told she woudl have a wish granted if she did it in a lifetime. She had been a victim of hiroshima (or nagasaki, i forget), so she gave it a shot but ended up dying young from the illness before she reached her quota. The point is, if it does exist in other cultures, it'll likely only be a surface similarity, I'd imagine. I remember reading in a children's book once that every leaf you catch from a tree in the fall before it touches the ground counts as a day's good luck... but i dont know if that's an actual superstition or one made up for the story. I can't remember the name of it either...
