1) JL4210A tower crane has competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.
2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected;
3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.
5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator

- Q:What is the scope of the installation and disassembly of self lifting tower cranes and the applicable range of the cost and the off-site transportation cost?
- The installation and disassembly of the existing self rated tower crane, the first cost and the off-site transportation cost quota are divided by the lifting moment 1000kNm and 2000kNm of the jack up tower crane.
- Q:Can the tower crane personnel install the construction elevator?
- As for the hoisting equipment, the licensed crane erection worker can install the construction elevator.
- Q:Why are there extra placards attached to the tower crane tower?
- 2. after adding the placard, it will increase the windward area of the tower crane and increase the wind load of the tower crane, so that it will deviate from the calculation load when the tower crane is designed, and will affect the safe use of tower crane.
- 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:The war is during 1899, and it's not the Spanish-American war.This isn't assignment, I'm just curious to know.
- Crane was a war correspondent, and had reported on both the Greco-Turkish and the Spanish-American wars. I am surprised you are so sure this poem isn't about the Spanish-American war; I suspect it is about war in general - certainly including the two wars Crane had seen most copiously.
- Q:Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?
- Use trigonometry, it's a triangle of forces.
- Q:As a building gets taller, the crane is raised. How is this done? And when the building is done, how do they get the crane back down?
- Sometimes the structure of the crane is built onto using the crane itself, building itself into a box. Then the crane lifts itself to the higher level. This can be done many times.
- Q:Mother, whose heart hung humble as a button the bright splendid shroud of your son,Do not weep. War is kind. Please help thanks for reading
- This is a very critical and harsh poem. Stephen Crane seems to have a more pessimistic outlook on life than other poems he has written, and nowhere else does that pessimistic outlook come through in his poetry than here. The pattern of the poem affixes a cynical, satirical statement after every statement of War is kind. For example, War is kind, Hoarse booming drums of the regiment, little souls who thirst for fight, these men were born to drill and die. The unexplained glory flies above them. Especially when Crane says the unexplained glory flies above them, he is making a powerful statement by questioning whether all the death and destruction is really worth it. This questioning is very important, because many wars are not really for what they seem to be for. There are exceptions of course, perhaps World War II and the fight to end the holocaust, perhaps the Civil War and the fight to end slavery, but for the most part, wars are usually conflicts between cultures over natural resources and disagreements over cultural values. The glory of war, the patriotism, the nationalism; Crane is trying to state that all of these emotions we associate with most wars are really made up so that generally people will feel better about their actions in the long term. Crane questions whether or not war is ever really worth anything to anybody in this poem. Crane clearly does not think so, considering the level of sarcasm he uses throughout the poem, especially at the end when he powerfully states Mother whose heart hung humble as a button On the bright splendid shroud of your son, Do not weep. War is kind. This is very powerful, and Crane very clearly points out that the glory of war and honor of battle are not worth much to a parent whose son has died, or wife whose husband has died, or child whose father has died. Crane's questioning of warfare is very relevant in today's war when we are as a country in what many people would call a meaningless war.
- Q:I've been wondering and haven't been able to find any information on it. Where does the sky crane go after it drops off Curiosity? You see it fly off in all of the videos, but no information is given on where it goes? Does anyone know?
- It was programmed to fly off to the side well away from Curiosity's landing spot, and then crash. NASA doesn't like to say much about it, because it dumped a mess of nuclear fuel! One of the 2004 rovers actually travelled to where its heat shield fell, and was able to photograph it.
- Q:How can you tell the difference between a mosquito and a crane fly?
- Crane flies are about an inch long, sometimes larger - just the body, not including the legs.
