Introduction
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: Does anyone know how to make an origami crane ring out of a single dollar bill? I know it's possible, because I've seen a picture.
- Sorry I can't give you the specific information you want. This site might link you up to a site that is more helpful. members.
- Q: Do they have to be taken apart... if so, how are they taken apart... by another crane? - but how did that one get there etc etc
- it depends on the crane over the road mobile cranes drive them selfs to the job site and they have a dolly for the conter weights and then on the larger ones a semi brings in the conter weights. Then on a latise boom crawler crane it depends on the size of the crane if its a small one say a 150 ton crane the body and tracks can usally be moved together on a semi and the lattice boom will come on a seperate truck and is usally assembled with a all terrain fork lift. Then say on a larger crawler crane like a 500 tonner the body and tracks and carrige all come in seperate peices and are ussally put togther with a RT crane(more on the latter) and these cranes are held together with massive pins i saw a crew build a 400 ton manitowac crane with 150 feet of stick in less then a day. Now if they have to add more stick like say 200 feet of main stick and 150 feet of luffing jib they will build it all on the ground and then another crane will help lift the stick up Then there are RT cranes or rough terrain cranes they are moved on a semi to and from the job site and usally require no assebley thats all i know about i cant say how a tower crane is build iv never see one build hope this helps
- Q: Is there a crane lifting chart where I can enter info. to determine what size crane I need, if so where?
- Sorry, it's not quite that simple.
- Q: how do they take crane off top of building?
- Depends on the building. Either a taller crane is brought in to lift them, or they're lifted by helicopter. And sometimes a building effectively builds itself, and the crane moves up with the construction platform after being constructed at ground level. Will still need a helicopter to remove it of course.
- Q: Or would it be better to custom order for my applications?
- Crane was good before they went out of biz. Howards Lunati Crower Reed cams was great before going out of biz. Comp does alot of custom grinds but I never been a big fan of comp. Core Hardness probs in past
- Q: I have a Manfrotto/Bogen 055XB tripod that says it supports up to about 15lbs. The crane I'm looking into getting is the Glidecam Camcrane 200 which says it has a payload of up to 30lbs. depending on the height. What would happen if I were to use this crane with my tripod?
- Please let me know where you will be so I can capture the video of your camera crashing to the ground. Because you overloaded the tripod, there will be no warranty coverage for anything. Yes, they can tell. ++++++++++++ I realized I had not provided an alternative... the crane specs also specify Camcrane 200 mounts on the 3/8 standard bolt found on the majority of medium and heavy duty tripods an
- Q: I need help to find the meaning of Chinese proverb A crane standing amidst a flock of chickens.
- Probably similar to, 'it stands out like a sore thumb.'
- Q: If you make 1000 origami cranes is it true that you will get a wish or good luck. This is based on a Japanese myth
- That depends on your wish. If your wish is to have 1000 origami cranes or your wish is that you become really good in folding origami cranes I would think it will come true. But maybe you could also wish for a smile from every stranger you give an origami crane to as a present, you might not even have to wait until you've made 1000.
- Q: when do i start bernie cranes missions gta 4?
- You have to have progress enough to be in Algonquin (the second island) and yo have to complete the Hostile Negotiation and No Way on the Subway missions before you encounter Bernie and are able to take mission from him.
- Q: We see lots of cranes doing some heavy lifting during construction. But how do they get so high up these buildings? And when construction is nearly done, how do they go back down?
- Those type of cranes have a support system that is continuously built as the building gets taller. The crane climbs up on the support system to reach the next level and climbs down to get down
