Product Description:
1. The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.
4. It adopts standard sections (for models of over 12t) of piece assembly structure, split structure stock, and assembled platform, which meet the transport requirements for standard container.
5. The extra-long boom is designed with a rope-supporting trolley, and the speed of which is 1/2 of that of the luffing trolley, which can achieve the most optimum rope-supporting effect. The structure has applied for national patent.
6. The lifting mechanism adopts speed regulation by frequency control or by eddy current brake series resistance, featuring good lifting performance; The slewing system adopts frequency control by torque electric motor or by coil winding type electric motor with hydraulic coupler, featuring smooth operation and small slewing impact.
7. All kinds of safety devices are reliable and easy to adjust; both the safety monitoring control system and traditional safety system are available, the double system ensures safety operation of the tower crane; the hydraulic system adopts low/medium pressure design, featuring higher safety and reliability.

- Q:Calculate the work the crane performs.
- Crane work = weight to be lifted x 6.95 m Weight to be lifted = 2.75x10^3 N + 1.20 m^3 (2.00 x 10^3 kg/m^3) (9.8) = 2750 + 23520 = 26270 Therefore, Crane work = 26270 x 6.95 = 182576.5 J
- Q:In Stephen Crane's novel The Red Badge of Courage, why is the war itself not even named?
- There are references in the book to events during the Civil War. In addition, the time of publication by this American author left no doubt in any American's mind which war it referred to. The Spanish American war happened after publication and the primary war on everyone's minds was still the Civil War.
- Q:Okay Answers community, I need your help. I recently received a thousand paper cranes for my birthday and I want to know, what's the best way to hang them up (like on fishing line etc.)? Also, at the moment I think I'd like to hang them up in my bedroom, in interesting patterns. Any suggestions for how to arrange the cranes, or other ideas for what to do with a thousand paper cranes? Just remember, I'd like to keep the lot!
- Thread them with fishing line as you stated in you question. Depending on how big they are, string them 20 to a string and put them on a dowel with 10 strings ,so you will have 200 cranes per dowel times 5 dowels !000 pieces.
- Q:Is Fireplace Crane a modern term for the swing-out metal arms that hang over a fireplace for cooking? e.g. like in dutch ovens or pots/cauldrons that hang over a fire. It sounds like a more modern term and I need to know if there is an older term. Thanks.
- You would mean one in the hearth, yes. An older term may be to call it a Pot Crane or Chimney Crane. That is most common to what you describe that it is affixed to the chimney and swings about. That does not swing, a lug pole might be from a green wood or iron hung above the fire with chain ... or if a Hearth Crane then a standing legged trestle (stands upon the hearth) and hooks affixed ... some with a pot crane attached. But either. You might also refer to it with it's counterpart, the trammel ... as in crane trammel. The trammel is the device hung from the pole or crane to allow the pot to be adjusted up or down depending on the heat required. In some cases the trammel can be just a series of S-hooks linked together, it can also be a chain with hooks, and is often a specific toothed device wrought by smithy. As a child we used hooks and hooks chain, thoe as a man I owned a sawtoothed trammel but hardly used it as I'd obtained a stew stove. My business partner Ebenezer insisted that a toothed saw trammel was frivolous and kept a chain and hook type in his home.

- Q:I've heard that daddy longlegs aka crane flies contain the most deadly venom of all insects. The only reason they aren't dangerous or deadly is because they have no mouth or 'straw' to inject the venom. But I'm not sure what's correct. Although they cannot harm us humans, is it possible for them to be able to inject the venom into other creatures?Also, I've heard that dragonflies contain deadly venom too, but just like with the crane flies, they cannot transfer the venom any way. Is this true?Any zoology professionals? Note: I may need correcting, and this may even be just an urban myth.Thanks for your time!

- Q:Old used 200 t crawler crane is available for purchase. What are the guidelines/ thumb rules for assessing its cost ?
- Supply vs demand Extreme examples: If the crane is no longer needed anywhere, the cost will be 0; no demand. If the crane still has a unique useable function and there is only one available, it's immediate cost will be very high; no supply. So, assuming that the cranes supply/demand is somewhere in the middle, the methodology for assessing it's cost would be to evaluate the following: * Where is it located with respect to where it is needed? (place value) * How quickly do I need it, and how quickly can I get the crane? (time value) * What alternative solutions are available? * How much do other similar cranes cost? * etc Hope this helps!
- Q:How do cranes get from one construction site to another without hitting streetlights, wires, car, buildings?
- They dodge by the stuff as they fly along. Duhhh
- Q:I would like to get some advice from Martial artists of the training that Crane style Kung Fu go trough especially the balance. I would like to learn how they learn to balance without difficulty and the training they go trough.
- I don't train in Crane style Kung Fu but I can give you some balance training tips. 1. Stand on one leg whenever possible (doing the dishes, waiting in line, etc.) 2. Walk on a Balance Beam (a wall, a line on the floor, a large long block, etc. can all be used as a balance beam), just walk heel to toe and work on staying balanced. When walking becomes too easy try practicing kicks on the beam, then spinning kicks, then jumping kicks (NOTE: if your balance beam is off the floor make sure you have a spotter when you do any jumping or spinning) 3. Practice, practice, practice Ask your instructor for more exersizes internet videos can be good but are unreliable and dangerous in the hands of people who don't know what they are doing.
- Q:What is an attached tower crane?
- Attached tower crane is due to the height of the building is relatively high, a steel connection in order to strengthen the stability of tower crane between tower crane and tower crane building, this form is called the attached tower crane.
