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:You see cranes on the floor which rise about 50 metres, but sometimes, when building high sky scrapers, I see cranes on the 70th floor or the 80th floor. How do they put the the crane so high up there when it can only go up high around 60-70 metres?
The cranes are built in the elevator shafts and moved up as needed during work progress.
Q:More specifically, do Sandhill Cranes eat squirrels?
They are more likely to eat fish.
Q:or is jason mraz just making up things for lyrics?
No. They are lifted into place in sections by one or more other cranes, the telescopic arm kind, which are either in a nearby street or on the building site. I watched several being built and then dismantled over a period of three years at a large development across the street from my house. However, I saw a TV programme about how they built one on top of a mountain, and there they used helicopters to lower the sections into place.
Q:What Japanese counter word is used for multiple origami objects...such as 1000 cranes?
1,000 cranes is counted using the bird counter (there's one specifically for birds or rabbits) so it's sen-ba-tsuru. It would depend on what you've made in origami. The most general counter would probably be -ko. one origami work ikko two niko three sanko four yonko five goko six rokko seven nanako eight hakko nine kyuuko ten jikko I think you could use it for almost anything that you could make in origami, though, (like senbatsuru) there could be a more specific counter to use depending on what you made, but there are so many counter words. If it's something flat, or you wanted to count origami paper, then it's -mai If it's a long slender work of origami -hon
Q:i am making a wired crane robot to pick and drop a wooden block of about 5*5*10cm dimension. I would like to know wat r the different possible lifting mechanisms by which i can lift the wooden block.Ideas other than the normal claw shaped lifters
There are different attachments that you can put on the end of your crane to pick up this block. You can make a set of forks (like a forklift) that would slide under the block (block would have to be elevated on a skid). You can pick up this block with a suction cup. You can also pick up the block by clamping the sides of the block by replicating a scissor type mechanism.
Q:please tell me thats not what i think it is O_O
It probably is cranes bill unfortunately. You could always contact the manufacturer be sure. They should have a number somewhere on the packaging. Lots of animals are used in cosmetic products. Sharks, whales and other fish are commonly used in lipstick ground beetle shell is used in most kinds of makeup. All you can do is use it up, because if you waste it then that animal died for nothing. If it really creeps you out, give it to someone who would use it. If I were you, I wouldn't buy this primer again... :S Hope this helps xx
Q:How many motors does the ZOOMLION TC6013A-6 tower crane use?
Model: YZRDW225M-4/8 power: 24/24KW speed: 1420/725r/minDirect search {ZOOMLION QTZ80 (tc6013) _ crane Manual Part 1 (Part Two)}, can also be found.
Q:How do I get on the cranes on the Highrise map in MW2?
NO okorder /
Q:don't its wheel provide the same amount of friction?
the capacity of a travelling crane relates to its resistance to tipping, and is dependent upon wheelbase, which can be extended by use of the outriggers, and counterweight (the big boxy thing at the back of the crane). Every lift requires a firm and stable platform which is what the outriggers provide. For every lift (weight) and reach (how far from the slew point), there is a limiting capacity factor. This is required to be posted within the operator's cab. The actual load lifted may be monitored by a load cell on a running rope (or other location), and through a computer control, limit the actual capacity of the crane.
Q:Do they have any symbolic-ness about them? any thing like that is good! THank you!
Cranes are considered sacred birds in many cultures. Volumes are written about their spiritual significance. Google Sacred Cranes.
