Characteristics of Tower Crane
1)This 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 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 material are the Samson & Goliath cranes in Belfast made from?
- They are cranes look at the YouTube video and read up on cranes that's what material they are made of.
- Q: Jon and Paul are folding origami cranes. If Paul works alone he can fold 100 cranes in 5hours. together they can do the same job in 3 hours. how much time would it take for Jon to fold 100 cranes alone? Please show your work. :)
- Paul does 100 cranes in 5 hours So in 1 hour he does 20 cranes In 3 hours he does 60 cranes and balance 40 cranes Jon does Jon = 40 cranes in 3 hours So 100 cranes = 100/40 X 3= 7.5 hours ANSWER
- Q: I am currently in the Air Force reserves as a heavy equipment operator. I really want to learn how to become a tower crane operator. How would I go about doing this? I live in CA.
- Hey Patrick, I was formerly a tower crane erector out of Washington DC. BUt, to yor question, I wold highly recommend you go to your town's Operator engineers Union Hall and inquire as to the qualifications and requirements to enroll in their apprenticeship program. Yes you will have to go thru the apprenticeship program. A tower crane operator is a coveted job among operators... You have to learn to hold your 'P for long periods as well as have great depth perception You coming out of the service, you should be given some preference Good luck
- Q: Denny Crane (played by William Shattner), and Alan Shore (played by James Spader) are partners in a Boston law firm. I would like to know if those those two are father and son in the series,
- SPOILER ALERT So far we have seen Donny Crane in Season 1's in Catch and Release we found that he isnt his son and than again in Season 1's Tourted Souls and Season 2's Squid Pro Quo
- Q: The mobile crane has a weight of 116kip and center of gravity at G1; the boom has a weight of 29kip and center of gravity at G2. Determine the smallest angle of tilt θ of the boom, without causing the crane to overturn if the suspended load is W = 38kip . Neglect the thickness of the tracks at A and B. Determine the smallest angle of tilt θ of the boom, without causing the crane to overturn.
- The key here is to simplify this as much as possible The equation is really: mass 1 x length 1 + mass 2 x length 2 = mass 3 x length 3 G1 * 6 ft = (G2 * X ft) + H3 * X ft) G1 = 116 kip G2 = 29 kip H3 = 38 kip Now it is an equilibrium of torque about the point where the boom pivots: 116 kip * 6 ft = 29 kip * Xft + 38 kip * Xft solve for X feet: X feet = 10.388 ft So the crane is in equilibrium when the load is length1 + length 2 times the mass = mass of motor * length 3 (10.388 ft * 29 kip) + (10.388 ft * 38 kip) = 116 kip * 6 ft The boom forms a triangle with the hypotenuse equals 12ft + 15 ft = 27 ft. The bottom of the triangle is 10.388 ft + 10.388 ft = 20.776ft So we have two sides of the triangle and now just need to find the angle where the triangle forms with those two sides: cosine of angle = adjacent side / hypotenuse cosine of angle = 20.766 / 27 = 0.7691 and the arc cosine of that = 39.7 degrees So rounding it off, angle of crane = 40 degree
- Q: Has anyone ever folded 1000 paper cranes? If so did your wish come true? If it did come true what did you wish for? :) Thanks so much!
- Yes i have. For a college friends wedding. The groom makes at least one crane. She was from Hawaii and it's one of the Philippine traditions. There's a story that goes along with it. In Hi there are companies that will take the flat cranes and form them into another design. like a vase or something that can be framed. I think her wish was just to get them finished within 1 week before the wedding... ;) We DID! That was luck in itself. not sure if her real wish came true.
- Q: In the case of tower crane operation, the operation should be stopped
- In case of six or more gales, heavy rain, heavy fog, heavy snow or tower crane, you should stop working
- Q: I ve read about crane flies and many experts say they do not bite nor sting. Ifor that is the case, what is the little piece of their abdomen that looks like a stinger?
- ovipositor?
- Q: I need to go to a tower crane school inside Las Vegas, where do i go? At least inside Nevada. Not Arizona or Utah or California.
- Statistically, they rank below familiar. The Clark County college District (Las Vegas) is recruiting instructors from out of city, or perhaps in another us of a (ordinarily the Philippines) through fact there's a scarcity. not many human beings flow to Las Vegas to flow into the coaching occupation. it rather is in all threat a marvel to no person. in spite of the fact that, like maximum college districts for the time of that us of a, the solid colleges are frequently in wealthier neighborhoods, and the undesirable colleges are frequently interior the final rich neighborhoods. this is extraordinarily lots comparable to that's in the different city. some colleges are greater valuable than others. In l. a. there's a great distinction between Canoga Park extreme college and Crenshaw extreme college, even although they're interior an identical college district. lots an identical might nicely be reported for the Las Vegas college District. There are solid colleges, familiar colleges, and below familiar colleges. As i discussed, as an entire, the District stories regularly occurring instructor shortages. There are only not that many qualified instructors that flow to the city for that particular occupation. The CCSD is ranked low in custom benchmarks including attempt rankings, instructor to pupil ratio's, etc. Vegas isn't understand for it rather is high quality of education, like say ... Boston. in spite of the fact that, in case you progression to a ideal section including Summerlin or Henderson, your babies will greater or much less attend and familiar suburban extreme college with a common adventure in different cities. in case you progression to North Las Vegas, or the Nellis section, there will be greater gang problems and a loss of inspired instructors through fact of a complicated coaching environment. many mum and dad % their properties here in accordance with which college their babies will attend.
- Q: We see lots of cranes doing some heavy lifting during construction. But how do they get so high up these buildings? And when construction is nearly done, how do they go back down?
- Those type of cranes have a support system that is continuously built as the building gets taller. The crane climbs up on the support system to reach the next level and climbs down to get down
