Description of TCD4021
1) CMAX TCD4021 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;
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:how do u build a hydraulic crane using syringes. it's a science project. can u give me websites or if u know details.
- Do okorder
- Q:analysis of jib crane?
- I would suggest that you delete this question and submit a new question with enough details for someone to give you an answer. This is not a question I can give you much help on
- Q:total motor kw-100kw,crane class-m6,the crane should be operated on ups as the conventional electric supply is off , back up time require-30 min.
- To account for the inefficiencies, and startup currents, you should have a 200 kW (200 kVA) inverter with peak power of 800 kW. The batteries would have to store and deliver about 150 kW. But lead acid batteries would need to be of a higher capacity to guarantee that power level for 1/2 hour, which calculates to 75 kW-hour. I'd say 100 kW-hour capacity. A large 12 volt battery can store about 100 amp-hours which translates to 1 kW-hour, so you would need 100 of this size batteries connected in series/parallel. I made a lot of guesses, you should get better numbers for the motors, the inverters and batteries for a more accurate calculation. An inverter of the size needed will not be a 12 volt unit, but probably 48 or 96 volts DC. so you need to configure your batteries in series parallel to get that voltage. Altogether, the 100 large batteries make this not a practical solution. There are lots of large cranes in the world, what do they use for backup? And why do you need backup. With no power, the clutches would keep the crane and loads fixed in position, my guess.
- Q:My science teacher wants to know why cranes make work easier rather than just lifting an object yourself. She refers to the formula of force x distance. So i have to compare (in a way) the work of a human lifting an object and a crane lifting an object. Grrrr.... I hate this project!
- The type of crane she is referring to ia a simple pole with a fulcrum placed between the person operating the crane, and the mass to be lifted. Imagine a weightless pole with a rope tied to one end attached to a mass of weight 224 lbs The pole is 9 feet long Let's say the human weighs 112 lbs, or half of what is to be lifted. Without a crane, it will be difficult to lift that much and swing it around. With the crane, though, let's look at the advantage when a fulcrum is placed under the pole and the person pushes down on the pole to lift the weight. First, note that gravity is in favor of the person to use their weight on the pole. Using physics, with the fulcrum place at x from the mass to be lifted, the downward force of the person is F*(9-x)=224*x or F=224*x/(9-x) now plug in some values for x and compute the force: x F 4.5 224 3.5 143 2.5 86 1.5 45 0.5 13 I started by placing the fulcrum exactly in the middle and then moving the fulcrum in increments of 1 foot closer to the weight to be lifted Notice that the more pole towards the person pressing down, the less force the person has to apply to lift the weight. Also, note that when the fulcrum is in the middle, the person must apply a downward force equal to the weight - which willl be difficult foir a person that weighs 112lbs. However, once the fulcrum is placed 2.5 ft from the weight, the person only need apply 86 lbs of downward pressure. Leverage. j
- Q:im 35 and in august i get my license back and i am going after my childhood dream of being a crane operator and was wondering how i need to go about achieving this?
- I am sorry I do not know where are you from as different country might have different requirement on getting a Crane Operator licence. Anyway, I believe the basic is the same: You need to attend a theory class on crane operations which usually include topics like design theory of cranes, slinging and lifting, signalling. After this, there will be a practical session to test your understanding and practical operations on an actual crane in the training center's facility. Good Luck and May You Attain You Dream :)
- Q:how do they get counter-weights onto high cranes?
- The top section of a tower crane, including the cab, boom, and counterbalance, is erected on the crane's base, using a portable crane. After that, there is a mechanism on the tower crane that jacks up the top and allows another tower section to be inserted under it to increase the crane's height.

- Im assuming it to be a modern Rolex Oyster 1/ it is much heavier than you would expect. 2/ the second hand appears to move in a continuous smooth motion rather than in individual 1 second ticks. 3/hold the face to your ear, you can actually hear the extremely rapid ticking 4/the face glass will not scratch nor break 5/when new it would be supplied in a green box containing rolex wallet etc. and Authentification certificate. My box and contents are in pristine mint condition, only ever opened once to take watch out when new. thus the box alone adds ?200 to value. 6/Any Rolex dealer will check the serial number for you. Also every reported lost/stolen Rolex is listed so dealer can check! 7/ Assume its dodgy, any Rolex dealer would buy it from him either for cash or in part exchange for any other watch! 8/ Rolex dealers all have secondhand watches for sale. 9/Decide if you really want a Rolex, they look superb but are not accurate time keepers! the inside is based on much cheaper Zenith movement. A Cartier is much better watch for the money! 10/ I bought my Rolex new and with hindsight wish Id bought a Cartier, which would have also held its value better. Take it to a Rolex dealer and have it appraised first. if he wont let you then walk away and buy from a real Rolex dealer, who will sell you secondhand for half new price, or less!
- Q:I'm 17 and I was planning on reading it for class, do you think it will be easy to read?
- Stephen Crane, Maggie is fantastic! I read it in school when I was 14 so I have no doubt you will have no problems in reading it. Maggie is the tale of an inevitable fall from grace on the part of a young, innocent girl trapped in the vicious world of New York City's slums. Yearning for acceptance and love, beaten at home by alcoholic parents, Maggie sets out with Pete, a local bartender whose cultured mannerisms elicit great respect from the impressionable young girl. However, when Pete spurns her for another, Maggie is ejected out onto the street, forced into prostitution to make a living. We last see her moving off, a huge, oily fat man in tow, for a darkened corner in the city's seedy underworld. If Upton Sinclair's The Jungle is a torrent of social anger and protest, Crane's Maggie is like a brilliant lightning strike, flashing across our vision and leaving us temporarily blinded. The book--scarcely 70 pages--is succint, brutish, and merciless. Crane allows his readers to form their own opinions regarding the characters. His innovative use of near-phonetic spelling to depict in the reader's ear the local dialect of New York's rough neighborhoods was shocking and difficult to comprehend when the book was first released. It lends Maggie an air of earthy legitimacy. Ultimately, Maggie is a cry for the plight of poor children--the souls we overlook with a callous unease mirrored in Pete's offhand, uncaring rejection of young Maggie's genuine love and affection. It is, without qualification, Stephen Crane's greatest and most moving achievement.
