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:With hi-rise buildings being constructed left and right, i was just wondering, how do they raise cranes? this has really been bugging me for a time now..
- Tower cranes are usually erected in one of two ways. You could lift the parts into place with a mobile crane with a telescopic boom which is taller than the crane being built. Some people ask why you dont just use the mobile crane all the time, but the tower crane has higher lifting capacity, longer reach and is cheaper. Some tower cranes are assembled at ground level. The long boom, cab and counter weight are assembled and then jacked up off the ground. A small bit of tower is then sliped in beneath the assembly and attached. The crane is the jacked up again and another portion of the tower sliped in. This is repeated until the desired height is reached. The first method is the most common.
- Q:For anyone who has read/studied Stephen Crane - do you know of any connecting theme within his most famous short stories (the open boat, the blue hotel, the bride comes to yellow sky, the monster)?I was think naturalism b/c it is so prevalent in the open boat but is really the only short story naturalism is in
- sorry, i haven't read any Crane short stories, but i'm a HUGE fan of his poetry. it's some of the most bleak, raw, yet honest poetry i've ever read.
- Q:Like those huge cranes on the top of buildings that are being constructed - how do they get them up there???
- With more massive cranes. Sometimes, they will put them up in pieces - and assemble them on top of the building.
- Q:Why do tower cranes need to be fabricated?
- The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3-4 times the same structure light steel wire rope (laboratory comparable conditions) with the research on the wear resistance of phosphating, and greatly enhance the possibility of. Manganese phosphating is bonderizing, can solve the wear problems of wire rope used in the process, according to the current market situation of wire rope, manganese phosphating coating of steel wire rope price is higher than that of plain steel wire rope, and prolonging the service life of much higher than the rate of price increase, so the phosphating coating steel wire rope daily use fee is only plain steel wire 30-45% rope, the use of lower cost, higher cost, smooth steel wire rope is eliminated. For reference only
- Q:What is the difference between a tower crane and a jack up tower crane?
- The jack up tower crane is a tower crane (that is an internal climbing tower crane) that is added and reduced by its own special device, namely, the standard section of the tower (that is, the attached tower crane) or the whole climbing tower itself.
- Q:How do they erect HUGE cranes without a crane?
- They use Hydraulics. I don't know if you have any understanding of Fluid power but a hydraulics system can lift up to 400% of its weight multiplyed by its density. There are other factors to consider such as cylinder size, flow, and pressure but these are usualy constants. For example: If the hydraulic fluid used weighs 5 lbs. per gallon and its density is .9 gram per cubic centimeter then 1 gallon of this fluid could lift 53.1441 lbs. A jack system is hydraulic
- Q:How many tons of tower crane QTZ80A lifting?
- QTZ80A 80 refers to the lifting torque of 80 tons after lifting meters.
- Q:What are the "2 magnification" and "4 magnification" mentioned in the lifting characteristics table of tower cranes?
- Popular saying: "car to hook this section of vertical distance, you see 4 wire rope is 4 magnification, you see 2 wire rope is 2 magnification.".
- Q:I read on wikipedia that in recent years, it has become less popular, but they do not mention why. I understand the philosophy of the art and it seems like Machida and Anderson Silva use similar styles. These are 2 of the best fighters in MMA. Can anyone shed some light on this?
- I can't comment on the people you mentioned. What I can say is that White Crane is a good style. BUT, it was never as popular as arts like Goju-ryu, Shotokan, Shito-ryu, and many others. It is curious that Wikipedia would say something like the style is less popular. But then I have always taken what I see on the internet with a grain of salt. Anyone can post any thing they want on the net. That does not make it true.
- Q:This has nothing to do with travel, I'm just curious. I hate it when the news doesn't follow up on stories they focused on earlier. Does anyone have a status update on that crane that was swaying in the wind during Sandy?
- My friend, that is a good question. According to the latest news conference from the Mayor, the crane's boom arm is secured to the structure. However, West 57th Street between Broadway and 7th Avenue is closed until farther noticed. In addition, the 57th Street-7th Avenue subway station on the N, R and Q Line is closed and trains are bypassing the station in both directions, according to the MTA. Good luck Native New Yorker
