Product Description:

1、Survey
Thank you for choosing the product of Huaxia Group. Please read the Brief Introduction carefully to know the tower crane well.
The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for 760Kn.m;the maximum hoisting load of 6t and the maximum working radius of 50m.The hoisting height of anchoring tower crane is 40m and that of climbing tower crane is 140m.
The tower crane has ingenious design, beautiful shape and simple structure .It is easy to operate and maintain, and is safe and at a reasonable price .It is an ideal construction machines for construction enterprises. It has hoisting mechanism, swing mechanism, top-rising mechanism and radius mechanism, which can work individually or cooperatively to make a high efficiency. The top-rising mechanism is used to raise or lower tower. The hoisting mechanism has 3-speed electronic motor respectively for high, medium and slow hoisting speeds. It has flexible swing mechanism and radius mechanism and slewing mechanism for vertical and /or horizontal transportation of building materials in one time.
The tower crane has complete and sensitive protection devices such as hoisting weight limiter, hoisting moment limiter, hoisting height limiter, radius limiter and swing limiter to ensure of regular operation. It also has rest platform, guardrail and other protection devices. Driver’s cab is at a side of rib and has big space and wide visual field.
The tower crane has excellent performance and is suitable for hoisting in short civil or industrial buildings or loading or unloading in ports or goods yards
The products of Huaxia Group are your best choices of construction machines

Q:How are skyscrapers been build ?no cranes can be that high?
The cranes hook to the side of the building and climb the steel frame as it is being built. The crane can only reach a few stories so it has to climb each story's steel frame as it is finished.
Q:does it really take a crane to build a crane?
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:I was looking at how to make your own camera crane... I was wounder can you make one from a microphone stand?
It might - but the center of gravity and the tripod might not be able to hold the weight of the jib, camera, counter-weights... and personally, I think it would be a pretty expensive mistake to watch my $2,000 camcorder fall and brake because the camera crane collapsed under the weight. A mic tripod is designed to handle about a pound of weight. A consumer camcorder, the jib and counterweights (and maybe a mic or whatever else you throw on there) can be between 5 pounds and 50 pounds. That's why companies like Kessler make what they make. And that's why the companies that makes lesser camera cranes (Cobra, CameraCranes, and others) never use a mic tripod. They use a heavy duty camera tripod or other LARGE, STRONG, item - not a mic stand.
Q:how do u bring a construction crane down?
That's a perfect application for a sky hook.
Q:HOW TO BUILD A WORKING CRANE?
you are totally just trying to avoid doing this work by yourself. anybody with two eyes can just look up crane on google and learn how it works. they are super simple just go to the library or something. or better yet go look at a real crane.
Q:Overlord 2: need help getting blue minions with crane thing.?
Just Go To The Water Path
Q:a horizontal joist carrying a travelling crane is simply supported over a span of 4m the mass of the crane is 150 kg?
figure shear first Let F be the max. crane load. for a simply supported symmetric load, the reactions at each end support will be half the total load. The reaction loads will also equal the shear load. 3000 N = (F + 150(9.8))/2 F = 4530 N The maximum bending moment will be the shear force times the moment arm of half the joist length 5000 Nm = [(F + 150(9.8))/2] N (2.0 m) 5000 = F + 150(9.8) F = 3530 N The bending moment max load is 1000 N less than the Shear max load so bending is the limiting factor The maximum load allowed is F = 3530 N 3530 / 9.8 = 360 kg As a form of exchange, please remember to vote a Best Answer from your results.
Q:Does anyone know how cranes are put in place?
Big cranes come in peaces ans they use smaller cranes to build it
Q:A crane mounted on truck droped the cargo on the truck itself, Is claim for damage to the truck valid?
The crane and the truck are one and the same vehicle, so I can't see why a claim on fully comp. wouldn't be valid. If this is not the case, then the crane IS the cargo, so surely the claim would go to the insurer of the crane, and not the lorry.
Q:I need help on finding the least amount of steps on how to make an oragami crane.?
Start with a square piece of paper. You got that? Fold the paper corner to corner to get a large right triangle, and fold it corner to corner again to get a smaller triangle. You got that ,or did I lose you. Open the paper, and you will see a big X. Never mind the X. We will come back to it. Now fold the paper side to side to get a rectangle, and fold the two SHORT SIDES to the X fold. Open and do the other two by repeating what you just did. Open the paper FLAT. You can now see a 4 pointed star. Along the four sides of the square, push down on the perimeter of the star to make the star come up. Fold down until you have a flat KITE. Make sure you have 2 flaps on each side. What you are looking at now is one wing, and the other one is in the back. The neck and head are inside the wings. Pull them out half way to expose them. Fold one side at the tip to make a head. If you did everything correctly, and hold under the neck with one hand and pull the tail with the other hand, the crane should flap its wing. Write back if you need more help.
