The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for400Kn.m;the maximum hoisting load of 4t and the maximum working radius of 48m.The hoisting height of anchoring tower crane is 29.7m and that of climbing tower crane is 90m.
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

- Q:A 3000-lb wrecking ball hangs from a 40-ft cable of density 10 lb/ft attached to a crane. Calculate the work done if the crane lifts the ball from ground level to 40 ft in the air by drawing in the cable.
- The total work done by the crane equals the potential energy gained by the wrecking ball and the cable; the potential energy gained is W = V_final = Mg L + ρ L g L/2 which is the final potential energy of the wrecking ball and the cable added together. In the case of the cable, you take the center of mass of it which is located right at the center (L/2). The result is then W = 3000*32*40 + 10 * 40 * 32 * 40 / 2 = 4096000 ft-lbf = (4096000)*(0.001285067) BTU = 5263.63 BTU
- Q:I have skills in my craft, I need finatial help for a n.c.c.c.o. certifacation.
- lol, yeah, how about just flip my burgers.
- Q:my 7 year old son swears that a crane jumper is a type of animal...any one heard of this??
- I googled crane jumper and came up with nothing. Not to say there isn't such a creature, that could be a regional name for it, it might be called something else.
- Q:Hello! My question was a when will type of question, and the results yielded a bird that looked like a crane, egret, or heron standing on one leg and one leg bent. I ve looked at online tea leaf reading symbol dictionaries for heron, egret, and crane but only found two meanings, and I m not sure if they are reputable sources or not, and how they would relate to time.This is a picture that resembled it closely, except the bird I saw is facing the exact opposite direction.Thanks for your help!
- Cranes are an extremely ancient symbol, there are folkdances based on their courtship display in many parts of the world, and evidence of this in prehistory too. Excavations at the ancient city of Catal Hayuk in Turkey uncovered the wings of a crane which seemed to have been part of a dancer's costume (google crane dance). Herons and cranes stand around waiting patiently for fish to come along and then move swiftly
- Q:Which kind is better, gantry crane or tower crane?
- Each has advantages, the use of different conditions, the use of different cranes, tower cranes can not move, but the lifting height can be very high, the door machine has tracks can be vertical and horizontal movements, lifting height, tower crane is not high.
- Q:i was reading this chapter in the book Catching fire (part of the Hunger Games Series) and this one part said she wrote Seneca Crane on the dummy with mud,, who is Seneca Crane?
- Oh, yeah! Ha ha, I got lost on that part too. It's hard to catch. Seneca Crane was actually the old producer so to say of the games. Katniss is calling them out, because she knows Seneca was punished due to the fact he came up with the fact to pretend two tributes could get out alive. The capitol blamed him for their failure to contain Katniss and Peeta.
- Q:Any difference?
- The crane part can be identical, but the vehicle part differs: in the former case it's a road-going (even multi-axle) truck, in the latter case it's an off-road vehicle with oversize all-terrain tires and appropriate traction and transmission capabilities. In either case, the vehicle must be stabilized on adjustable hydraulic struts before hoisting.
- Q:Two cranes can unload a ship together in 8 hours. The faster crane takes 12 hours less than the slower crane, if each were to unload the same ship alone. How long does it take for each crane to unload this ship?
- If an answer of -4 hours is expected, pl. excuse. The practical difficulties of the faster cranes are constraints - the loading to / unloading from any crane is tricky, time consuming are with practical problems. The ship. yard where it is angered, the type of the cargo also decide the swiftness of unloading ; so it is not simple ratio !
- Q:how do you think the auther of the legend of the sleepy hollow developed the charactor ichabod crane?
- I hope this will help you.
- Q:You know those machines you pay and get like 15 seconds to operate the fricken metal hand?Can you give me some tips?
- make sure you find something that isn't trapped by anything else in the pit.. line up the crane one the front, then move over to the side and line it up... these machines used to be a lot easier 20 years ago, but now the arm doesn't apply much pressure.. it has to be lined up just right or you will never get anything...
