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:Kindly name the companies.
which okorder / -indian Search engine-quite effective for local searches..
Q:Calculate the work the crane performs.
Crane work = weight to be lifted x 6.95 m Weight to be lifted = 2.75x10^3 N + 1.20 m^3 (2.00 x 10^3 kg/m^3) (9.8) = 2750 + 23520 = 26270 Therefore, Crane work = 26270 x 6.95 = 182576.5 J
Q:im so frustrated because ive tryed everything and im obsessed with this book it would really help if someone could find a way for me to read it for free online. i cant find it at my library.please and thank you:)?
did you ever get to read this book

probably becasue they are proud of their country
Q:why are whooping cranes on the endangered species list?
At one time, a few decades ago, there were only 21 (or 28?) of them alive. There was a significant effort to captive breed some, and save nesting areas for others. Now there are more, but their numbers are low enough that it's not a stable population yet.
Q:Lifting mechanism in tower crane: M5. Luffing mechanism: what does "M4" mean? Seek expert answers
It is the work level of the organization, representing the working hours and load sizes of the institution. See GBT/13752 or GBT/3811 for specific explanations.
Q:ok I found an injured crane what do I feed it?
Cranes are omnivores. But I would feed crane with vegetarian stuff like grain, berries, plants, roots, seeds, stems, bulbs, fruits, nuts. But if you want make it non vegetarian then rodents, fish, amphibians, snakes, rodents, lizards, small fish, frogs, shellfish, mollusks and crustaceans.
Q:How many tons are tower cranes QTZ125?
1 tower crane QTZ125 has 8 tons, also has 10 tons.2, QTZ125 tower crane is Shandong fuiou Co., make full use of group technology, modular design and finite element analysis technology, the "computer design platform for tower crane tool designed for the newest type of hoisting and conveying machinery.The machine is a horizontal boom, trolley luffing and upper slewing hydraulic lifting crane.
Q:What is the difference between a tower crane and a jack up tower crane?
Tower cranes, because there is no running mechanism, so tower crane can not do any movement. Fixed tower crane can be divided into the tower height invariant and Jack up. That is, the jack up tower crane is a kind of fixed tower crane.
Q:Please help me. I have to write and essay about it and i cant find it on the web!! no anywhere i can get it from ONLINE?!?!?! any particular search engines?
