TC4708

TC4708tower crane is a new-style hoisting and transporting machine designed to meet the need of assembling high-level construction equipment. The product is an upper rotary self-lifting kind with horizontal jib, trolley amplitude. The length of the jib is 47m, rated maximum lifting capacity is 4t and rated maximum lifting moment is 400kN.m. The following is the main characteristics.

1. Wide applicability. The applicability is ranging from civil construction in small and medium cities, to high-rise, multi-layered civil construction in big cities. It can also be used in the construction of multi-layered industrial factories, in the slip-form construction of huge chimneys and silos and in goods loading in port or goods yard.

2. Easy to assemble and disassemble.

3. High speed, easy adjustment, stable operation and high efficiency. Low speed with heavy load and high speed with light load can be realized through lifting structure. Two kinds of speed of trolley can meet operational needs. Open stopper is equipped to slewing structure, enabling precise placement and easy assembly of crane.

4. Complete protective and reliable safety devices. The product is equipped with weight limit, moment limit, height limit, trolley limit and slewing limit to ensure normal operation. Besides rest platform, protective railings are also equipped.

5. Driver’s cabin is separately set. It is broad, bright, comfortable, safe and easy to operate.

Q:I'm researchign for this demonstration speech on origami and uncovered a legen that says in the Japenese custom if you fold 1000paper cranes you are granted a wish. Just wondering, has anyoen ever tried this? and the outcome?I'm goign to do it this weekend!: There are many stories of this, who is to say if they are true or not. A young girl dying of cancer folded 1000 paper cranes and she miraculously recovered. I don't think it is like a I really hope Jimmy takes me to the prom!! type wishing though. It is a nice thought nonetheless. . . .

Q:What windproof devices should be set up for crane work?: 2. torque limiterTorque limiter is an integrated safety protection device for jib cranes.We know that an arm crane represents the load condition from the moment of gravity. The load moment value is made up of product weight, amplitude decision, amplitude value is determined by the product, the boom of the crane arm length and angle cosine so that the crane is overloaded, in fact are the weight, arm length and arm angle limit, while also considering the working conditions and other parameters as well as constraints effect of control is more complex.At present, the widely used microcomputer controlled torque limiter can synthesize various situations and solve this problem better. The torque limiter consists of a load detector, an arm length detector, an angle detector, a work condition selector, and a microcomputer. When the crane to enter the working state, the computer will detect the signal input parameters of the actual working state, after operation, amplifying and processing, and advance into the rated load moment value, and at the same time in the display to display the corresponding actual values. When the actual value reaches the rated value of 90%, it will issue a warning signal when the actual value exceeds the rated load when the alarm signal, at the same time the crane to stop dangerous direction (lifting, boom, arm and rotary movements continue to drop).

Q:please be specific! thank u so much: I have no idea Im trying to find that out too!!!

Q:When making 1000 origami cranes, do all of them have to be the same size? I already made some of varying sizes. Does it matter? I hope not.Thank you.: They can be made of anything, and they can vary in size, so you're okay.

Q:i need six colors mentioned in the story and wat each one means thanks :): From: The Open Boat By Stephan Crane. These waves were of the hue of slate... ...save for the tops, which were of foaming white... In the wan light, the faces of the men must have been grey. ...the color of the sea changed from slate to emerald-green... ...wild with lights of emerald and white and amber. ...near patches of brown seaweed... ... at the men with black bead-like eyes. ... marked by dingy clouds, and clouds brick-red, ... Ain't they peaches? A faint yellow tone came into the sky over the low land. ... a small bluish gleam on the edge of the waters. ... with a sky of pure blue...

Q:How much does it cost to build 18, 22, 35, 40, 50, 70, 100, and 120 ton cranes?: You would have to contact the crane manufacturer. Each size would have different cranes that meet that requirement, eg portable versus not portable. That's assuming those are total crane weight numbers? Or are they lifting capacities?

Q:How to choose tower crane in engineering, such as arm length and lifting weight?: 1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.

Q:In the end of chapter 16 of Catching Fire the 2nd book of the Hunger Games it says the name she wrote in the dummy, was Seneca Crane. Who is that?!,: In the first book/movie the head gamemaker, so the guy who chooses what happens every second of the hunger games, was Seneca Crane. He was executed at the end of the first book, by eating nightlock, the berries the star crossed lovers used to kill themselves with (unsuccessfully).

Q:because i have this huge sofa i need to get to 2nd floor but i cant coz the staircase is too small: Talk to a lumber yard that has a boom truck. Ask them how much to do it. A boom truck will cost much less than a crane. A boom truck can reach 45 to 50 feet. In this economy they are looking for anything they can get. They will most likely do it. But when really busy they wont. But things are slow. Builder 30 years. A crane will cost about 250.00 of the first hour. with a one hour min.

Q:I'm researching Stephen Crane for an English project and I need to how Stephen Crane's works effected others. Thanks for the help! xP: I'd mention his book Red Badge of Courage and how it changed the war novel for American and English writers. You can look at books like Catch-22 , MASH, or Hemingway's war novels and find that personal voice that Crane used.
