Introduction

The JXL trolley mechanism is a self-designed new product based on the advanced foreign technology, and got the national utility mode patents.

The JXL trolley mechanism constitutes torque motor, half built-in planetary reduction gear wound roll, rack, and other components, which has advantages of smooth shift from the brake, transmission efficency, low noise, compact structure, and brakeing safe, reliable, accruate positioning, pleasing in appearance, and other characteristics.

After changing variable-frequency speed regulation motor and electronic system, the institutions can be changed to JXF trolley mechanism, which has the advantages of zero velocity brake, starting speed more stable and is more suitable to large tower crane and the trolley running on a demanding place.

Q:lifting a machine by two crane?
Not enough information. What is the load weight? What is the size? How do you plan to attach to the machine. What size is the beam cross section? Capacity of the cranes? And so on. It sounds like you might need an engineer to supervise instead of relying on Yahoo Answers for an answer to a potentially deadly if not expensive way to fail.
Q:What time period did Stephen Crane write?
Crane was from the late Victorian era, timewise. His prose writing was American realism or naturalism, but his poetry was more modernistic. The Edwardian era began just after his death in 1900. Although his most famous work was The Red Badge of Courage, he was not even born during the Civil War.
Q:How do tower cranes stay balanced when they have very long booms and very heavy loads moved inward and out?
I think the counter weights are connected to a pully system that directly interacts with the boom and hook movement. This way it can put more or less pull on the weights according to the amount of weight or position of the weight on the crane.
Q:I am a fellon, I made a mistake and I need help getting my crane certifacation. so I can work.?
Without okorder.com/
Q:can someone please explain how a crane is lifted from floor to floor while building a High rise?
Ever seen a Chinese acrobat build a stack of chairs? Hydraulic jacks, just under the operator's cabin, lift it a few feet, so that more support structure can be built around the top. Then, the jacks are retracted and reattached to the new section. When needed, the process is repeated.
Q:How do they erect the construction cranes?
How do they erect the construction cranes? Not very well according to the news of them toppling down of late. Seriously, the cranes are lifted upward one or two floors at a time as the building progresses upward - this is usually accomplished by pulling them up into place with heavy cables and powered winches.
Q:why are tower cranes positioned the way they are when they are shut down for the day?
It might be that specific company or something. I'm on the Las Vegas strip right now, and there are dozens of cranes pointed every which way.
Q:Where can I find the short story Cranes on the internet?
If okorder.com In the search bar there, select the books category, then type the title of the story into the bar, and click go. You will be linked to the page where you can purchase the book very cheaply -- about $5.00. Also, there is a review of the story describing its plot. Additionally, you can type into the search bar of your computer: short story Sadako and the Thousand Paper Cranes; on the page you receive will be a link to Wikipedia where the plot is explained. If you are looking for a story simply titled Cranes, I was unable to discover that one. Sorry!
Q:Blue Heron, Crane, or Egret?
Blue Herons are (surprise) bluish gray, long legged long necked birds found in fresh water marshes and lakes, ponds. They are found though most of the US. There are several kinds of egrets, but I assume you are thinking of the great egret which is similar in size and shape to Blue Heron but is all white. They are found more around the coast from the Southern mid Atlanatic to Texas. They tend to be more in salt water locations or in rivers near the coast. There are several kinds of cranes, 2 inhabit the lower 48. One is a whooping crane and incredibly rare , nearly extinct species that breeds in the Arkansas/Texas area. Most likely any crane you would see is as sandhill crane tht inhabits various habitats in the interior of the country. It is smaller than the heron or egret, is grayish in color and has a red crest on its head.
Q:why arent there more female crane operators?
Have you failed at something? A physical for a job? Have you failed a civil engineering exam? Why take the blame yourself. Scream sexism By the way most crane operators don't pee out of the crane. Most urinate into a bag of gelatin that can be disposed of later. There is a special cuff for females to use with the bag
