Product Description:


On the basis of absorbing advanced foreign technology, our company developed the JXD trolley luffing mechanism independently for small and medium-sized tower cranes.

This series of trolley mechanism consists of electromagnetic double-speed change-pole motor, semi-concealed planetary reducer, drum, frame and other components.Its characteristics include compact sturcture, high driving efficiency, and low noise, safe and reliable braking, accurate positioning, pleasing in appearance and so on. When users have higher requirements to the trolley running, variable- frequency speed regulation motor with the same interface and relevant electric contol system may be changed to form the variable-frenquency speed regulation trolley mechanism.

Q:What is the email address for the cartoonist Brian Crane?
Try comics and animation.
Q:What is the improvement of Overhead Crane in Shipbuilding?
Hello, 1. Modularity: You can build ships (larger ships) in modular sections and have the crane lift these modular sections and put them into place for final assembly. This is one major advantage that was not available back in the day
Q:How are those really tall construction cranes assembled ???
I assume you are talking about a tower crane. From a distance, it looks like a T with one side shorter than the other. First, you need a good foundation for the crane to sit on. Next, you have a large mobile crane. With the mobile crane, you construct the tower (metal framing going up), the cab (where the operator sits and the motors), the boom (the mast out front) and the counter-weights (on the side opposite the boom). For the most part, this will get you a tower crane that will be about 200 feet above the ground. Most tower cranes today are self-jumping. Once you are ready to jump the tower crame (i.e. insert another section of the metal frame) there are hyraulics that lift the boom, cap and counterwieghts. This will create a gap in the metal frame. The tower crane will then pick up a section of frame and hoist it up and the ironworkers will slide it into place. The top section will be lowered down onto the new frame piece. The hydraulic jacks then get re-attached higher up to continue the jumping process. That is how you get a crane to build a 50+ soty building. By the way, once the crane is about 700 feet in the air, (if you have the stomach for it), it is a blast to ride out to the end of the boom.
Q:Best structural crane design?
Balsa Wood Crane
Q:In Stephen Crane's novel The Red Badge of Courage, why is the war itself not even named?
There are references in the book to events during the Civil War. In addition, the time of publication by this American author left no doubt in any American's mind which war it referred to. The Spanish American war happened after publication and the primary war on everyone's minds was still the Civil War.
Q:Can anyone help me with my irrational fear of crane flies, wasps, and moths?
There is a reason you fear these, you allow it. Moths and crane flies are totally harmlees, and really nothing more than a nuisance. Over time you develop a fear of them touching you, and eventually even being near them. Because you dwell on this instead of completely ignoring them, you literally brainwash yourself into fearing them. You need to change the way you think about these critters, preferably, not thinking about them at all. At times when they are a nuisance, just deal with them. I had a moth last night fluttering around my lamp, and it finally landed on the curtain. I grabbed it and tossed it out the door. no more moth. I like to sit on my porch at sunset, sometimes I'll watch a little barn spider come out from behind the lamp and spin her web. Often a pesty crane fly will want to buzz in my face,and I just shoo it away. If it gets persistent, I grab them and toss them into the spider web.No more crane fly. (I get those pretty little green lacewing flies too) It is really a matter of learning how to just ignore them, and deal with them when they are a pest. Sounds like you pretty much ignore spiders, try the same with the moths and crane flies.
Q:i have a knife with either 2 flamingos or cranes on the blade does anyone know the maker?
Sounds of the Asian descent,
Q:Is tower crane a tower crane?
It is tower crane, tower crane, commonly known as tower crane, tower crane --- tower crane. Ha ha, hope to adopt.
Q:Origami Cranes, 999 or 1000?
It is susposed to be 1000 cranes. You string them in 10 sets of 10 cranes. [thats how I remember!]Can you send me your way of folding them? I can't find one that works right for me, they always turn out a little wrong. :[
Q:Hunger Games Question: Why is Seneca Crane important enough to be in the movie?
(Well Seneca Crane plays a big part in Mockingjay (Book 3). He's also the one that saves Katniss in the end of Catching Fire (Book 2). If you haven't read the last 2 books yet I would seriously recommend it before you see the movie. But yeah I'M SO EXCITED FOR THE MOVIE! XD) WAIT! Sorry scratch that. Seneca Crane was executed for letting both Peeta and Katniss live. Yeah that's right. Don't listen to what I wrote above. It's late and I'm tired... XD
