Main Features

1) tower crane is one of the key product of CNBM company, which have 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; The max. attached height can reach 180m.

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.

The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.

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:why are whooping cranes on the endangered species list?: Today okorder / This is a very good website. I hope it helps, and if you liked my answer please leave me postive feedback. Thank You!

Q:Basically what it says on top. Also provide maybe a video to prove it.: I think of myself greater because of the fact the paper plane sort.....going with the breeze and letting it take me the place it is going to. additionally, cranes are no longer very severe-high quality once you get too close to to them and could attempt to %. your face off in case you verify out them humorous.

Q:I need to know exactly how much weight they can lift also how much do they weight?how long is thier life-time?in what temprature they can work?does mosture do any harm to them?for installation , do they need foundation?the exact height and width?: You need to be more specific. The lifting capacities for container cranes varies significantly, as does any other crane. Some of the variation is based purely on load (horsepower) availability; some is based on speed (rpm) for lift/drop portions of the cycle. Cranes like these operate year-round, at ports all over the world. Some ports have average ambient temperatures in the range of 45 C, with highs up to 60 C. Others can be as low an average as 10 C, with a low peak as much as -50 C. Moisture will, over the long haul, harm them - they're metal constructs, and thus are prone to oxidation. Using corrosion-resistant materials and/or coatings will certainly prolong their usable lifespan. The crane drives (electric motors and power electronics) are also susceptible to moisture and other contaminants. All true dockside cranes require some sort of permanent foundation; it's usually part of the pier construction itself. However, there are portable cranes that operate without one. There is also more than one crane manufacturer out there - all will have their trade secrets that will make each look a little different than the rest. It will generally also reflect in their operation parameters, and in their expected life cycle.

Q:well I am making 1000 paper cranes... I am on 18... but how do you string them all together anyone know?: There should be a tiny hole at the bottom. Thread some colorful embroidery floss onto a needle, poke the needle through the hole in the bottom and straight up through the point at the top (on the crane's back). You can string one after another like this. You'll have to just take a guess on the length of the thread that you'll need, and be sure to knot it on the end. I have dozens of strings that I've made and given to friends like this. If you like, you can separate each crane by a colorful glass bead. It looks really cheerful.

Q:how do they take crane off top of building?: Giant crane is used helicopter to lift it up and bring it down from very tall building.

Q:How much should the verticality of a tower crane be controlled? Thank you: No, the wind speed is not more than 3m/s, the independent state tower (or attached state highest attachment point above the tower axis) lateral verticality tolerance is 4/1000, the highest tower axis perpendicularity allowed attachment line below the point of difference is 2/1000.

Q:please help me solve.. i really don't get itttt: 1 horse power = 746 watt. So the work W done by the crane in 15 s is given by W = 8*746*15 J . So the distance, S through which the crane lifted 100 kg, presumably at constant speed is given by 100*9.81*S = 8*746*15 or S = [(8*746*15)/(100*9.81)] = 91.25 m

Q:i have a 100 ton american crawler crane. how do i calculate the psf, for this equipment.: Not sure what you are asking exactly... Are you saying that you have a crane with a capacity of 100 tons and you want to know the pressure on the soil where the crane is positioned? In this case, you take the capacity (in pounds) plus the weight of the crane (in pounds) then divide their sum by the area of the tracks on the crane (in square feet). This will result in pounds per square foot or psf as you wrote above. These are example estimates, they may not be anywhere near the correct answer, this is simply how to do the calculation. Assumed Capacity 100 ton = 200,000 lbs. Assumed Weight 105 ton = 210,000 lbs. Assumed Area of Track = 200 square feet Note: 1 U.S. ton = 2,000 pounds = 2,000 lbs. 410,000 lbs / 200 square feet = 2,050 psf There's a start, now you just need to find out how much it actually weighs and how long and wide the tracks are to get the area of the track on the ground. I hope that answers the question you were asking.

Q:If so, what time of year?: oops, sorry, I had read crane flights. Crane flies - what we call 'cousin' or 'tipule' - are quite common in the Rhone valley, including Lyon though not as common as their dreaded relatives the mosquitos. They usually go dormant in winter as it is quite cold in Lyon during that time. They are harmless to Humans, even if they look terrifying but are a nightmare to gardeners. Edited: Wise Owl, I have lived in Lyon as well and I have seen them often enough to find it usual, though not every day of the week. However I lived near the Tête d'Or Park so the greenery might have had an influence on their presence here.

Q:How to select tower crane type according to the height of building? Seek explanation: Choosing tower cranes is not based on height, but is based on the coverage area. The height is only a reference value. Now high-rise QTZ can be attached to the wall, so height is not a problem. Let's talk about the shape of your building, and the best of the 5
