Q: Notice of tower crane: Please refer to the technical regulations for the safety of installation, disassembly and use of tower cranes in construction;The following is copy:3 installation of tower cranes3.1 conditions for installation of tower cranes3.1.1 tower crane installation unit must have the construction administrative departments issued the contracted professional qualification and heavy equipment installation engineering construction enterprises safety production license. Tower crane installation units must be engaged in the installation of tower cranes within the scope of qualification permit.In addition to the professional and technical personnel who have the qualification standard, the installation units of 3.1.2 tower cranes shall also have professional personnel who are in line with the project. The person in charge of the project, the project manager and the full-time safety management personnel shall have the certificate of safety production inspection. Tower cranes, installers, electricians, drivers, signal engineers, cable operators should have special construction operation qualification certificates.3.1.3 construction units shall sign professional contract for installation engineering with the installation units, and make clear the responsibility of both sides for safety in production. In case of general contracting of construction, it shall be signed by the general contractor and the installation unit.

Q: I live in the upper stairs of this apartment with a huge light right next to the front door, and a bunch of Crane Flies kind of hover around it. So whenever we open the door, some of them come in, and it's a big problem. Especially to a someone like me who's deathly afraid of big bugs.So we want to buy the Raid spray, but we don't know if it would work. The Raid: Ant and Cockroach spray didn't work that well, but that's understandable.sooo anyways, has anyone tried the Flying Insect Raid on Crane flies?: Carburetor cleaner will destroy a roach instantly and costs less than Raid.

Q: what is that max torque it can with stand when the max laod it can handle is 811 N?i can NOT get this question, its driving me crazy!HELP????? thank you: I don't know if this is a question you got out of a book, or something you are trying to apply on a jobsite, but I would hate to see you try and use this approach with expensive equipment and innocent lives in the balance. Learn to use the crane charts. They account for many factors, including the weight of the boom, the tipping moment, the strength of the ropes, the engine's power, and the structural integrity of the boom.

Q: Has anyone actually folded 1000 paper cranes? i want some proof: no. But I have read the book sadako and the thousand paper cranes. I was so sad when I read that. I have always wanted to fold A paper crane.

Q: i will like to crane operator?: You made a statement, you will like to crane (an) operator. Which operator is it you are going to like to crane? If you mean would you like to operate a crane, that is up to you. If you mean can you be a crane operator, that is up to an employer. You need to be employed as one, and that probably means training and experience before being allowed to operate cranes for him/ her.

Q: Which one is right? Are there two different kinds? This bird is confusing me.: Whooping crane, largest bird in North America, named so for its call.

Q: how do construction crews put up a crane?: They assemble it on a concrete foundation using a mobile crane. To grow taller, the top unit of the tower crane has a jacking mechanism that lets it raise itself up and insert another tower section.

Q: River? Please give me links. I have seen some videos on youtube about the plane getting lifted out, but none of the crane which is what I was wanting to see.: any news site because the Associated Press carried the story

Q: crane signals?: There are hand signals which are used by men not operating a larger crane for hoisting,lowering,stopping, holding and slow. There are more but you would get a better idea in the link below. Scroll to pictures. 2nd link is a place to purchase placards or magnetic backed visuals.

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.
