70RCS25 Series Hoisting Mechanism
Introduction
Such production are independently developed and manufactured by our company based on mature technologies of French Potain Company with rated hoisting weight of 8t,10t,12t and 16t.Horizontal and vertical motor mounting types and different rope capacity are available for users. Such products adopt two winding 3-phase asynchronous motors and series excitation speed regulation circuit which realize interactive effects via gear assembly to constitute speed regulating system with features of wide range of speed regulation, high-speeding hoisting, low-speed positioning, stable speed change and high working efficiency. The mechanism adopts L-shap in overall layout and employs winding drum of Lebus grooves with large rope capacity, which can prevent disorder in case of multilayer winding of wirerope and satisfy wide use demands of high-rise building construction, hoisting of large equipment & construction member, etc.

- Q: My great grandparents' kamon was the crane and I was thinking of getting it as a tattoo for a symbol of my family.However, I'm not sure which it is. I've bought a book on Japanese Crests especially for this, and saw a couple of crane crests but was wondering if there's an origami crane kamon? And if there is, what is the meaning of it?Thank you very much for the help in advance!
- Crane Family Crest
- Q: is this normal? I mean VERY VERY afraid. I mean i won't scream but if i see a someone (except other guys) i will hug them tightly and beg for them to kill them... and how can i change this?

- Q: What does a track type tower crane look like? In that case, use?
- The rail type multi characteristic tower crane consists of track, door frame, main arm, auxiliary arm, hook and so on. Its features are: A, crane through the door frame (2), supported on a track (1); B, the door frame (2) is provided with a rotary bearing (3); C (3) is arranged on the rotary supporting all kinds of machinery and equipment (4), and balance weight (8); D, the main arm (5) the jib (6) through the bearing cable (7) is installed on the rotary support (3); E, the main arm (5) side arm (6) and Russo (7) can have a variety of length combination; F, a main arm, jib all tube truss structure; G, hook pulley h, equipped with a variety of rate; the torque limiter (10) and amplitude detection device (11); I, operating room in slewing bearing (3); J, self moving use winch is luffing winch main arm, mounted on a rotary support (3).Track type multi characteristic tower crane. The utility model is especially suitable for power construction and hoisting operation. The slewing support on the track type door frame is provided with a main and an auxiliary arm frame, and various variants can be formed through different combinations. Its maximum torque of 3360 tons meters, the maximum lifting capacity of 140 tons, the maximum working range of 60 meters, the maximum rise of 120 meters. The utility model can be carried in the lifting, and the work is smooth and safe. The main and auxiliary arms are all truss structures, light in weight. The electronic torque limiter and other safety devices are adopted, and the 130 meter high machine can be installed by itself. This machine can also be used in petroleum, chemical, metallurgical and other large projects.
- Q: determine the maximum load the crane can support in kg if the bending moment on the beam is not to exceed 5000 Nm and the shear force is not to exceed 3KN when the crane is positioned at mid span
- figure shear first Let F be the max. crane load. for a simply supported symmetric load, the reactions at each end support will be half the total load. The reaction loads will also equal the shear load. 3000 N = (F + 150(9.8))/2 F = 4530 N The maximum bending moment will be the shear force times the moment arm of half the joist length 5000 Nm = [(F + 150(9.8))/2] N (2.0 m) 5000 = F + 150(9.8) F = 3530 N The bending moment max load is 1000 N less than the Shear max load so bending is the limiting factor The maximum load allowed is F = 3530 N 3530 / 9.8 = 360 kg As a form of exchange, please remember to vote a Best Answer from your results.
- Q: I was wondering how those guys/gals get up to their posts. Is there some type of elevator or do they climb up everyday? I'm talking about those big cranes on contruction sites. the huge ones.
- There are ladders leading up there. Crane operators are fit enough to do the climb at least twice a day. I climbed cranes on weekends as a hobby photographer to take panoramic shots from that nice position up there. It was quite a climb to get up more than 200ft (60m)
- 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: what are the effects of fiction in cranes?
- Uh.... Do you mean fRiction? And cranes... as in the machine or the bird..... Try to be specific.....
- Q: In stephen Crane's The Open Boat does the correspondent change from the beginning of the story to the end?
- Wow. I haven't read this in years but I loved this shortstory. Yes, the narrator (or corespondent) definitely changes and the nature of this change is made explicit in the closing passages of the story where, if I recall correctly, he says that he feels as if he has become an interpreter of nature.
- Q: Which one is a better investment? I can get both for 200dollars
- Hi JAY ... Neither is a large investment compared to the time and work using them involves. Lifting an engine requires a lot of work getting stuff disconnected and , even worse, reconnected when put back. Of the two, I believe the crane would more useful. When considering such projects, you should take into account all your work and time the project will take. Whatever, I wish you the best.
