- Q:my father is owning a crane manufacturing business I hav given my ssc wat should I study after ssc IT, mechanical engg., design engg. and others (plz. specify) ?
- Without being too critical, the first thing you need to do is improve your English so that you will be a huge help in the company whether in engineering or sales. Cranes require lots of engineering in weight handling (mechanical), automation and controls including instrumentation (electrical) and a tertiary field in engineering is in stopping and starting (clutches and brakes) which can be mechanical or hydraulic engineering. A new filed is metalurgy which is concerned with the way metals perform (stress), lighter,stronger, etc. Take your choice. Mpho
- Q:how do they make those tall cranes so TALL?
- They come in sections. First few are fitted with a smaller crane anthe rest fit onto the side of the assembled base and are lifted up via the internal lifting mechanism then they just slot themselves into place forming another level containing a lift for the next piece and so on until the right height is achieved. I'm sure that's how it works. either that or it's magic
- Q:The question is: A crane has a power of 500watts, and is pulling a 142kg. What is the velocity of the pulling of the crane?Please help and thanks!
- I don't remember ever doing a problem like this, but I will try to solve it. P = W/Δt, P = Fd/Δt P = Fv Force required to lift the 142 kg object; F = 142 * 9.8 F = 1391.6 N Therefore; P = Fv 500 = 1391.6*v v = 0.359 m/s So velocity of the crane is 0.359 m/s. Is that right?
- Q:Hi,I am looking for study for Design, Calculation and selection of Overhead Crane supporting Columns. (Not the Crane runner way beams ) Could you please suggest me the suitable references on internet?Thank You !

- Q:Calculate the tower crane gantry crane
- It's a gantry crane, not a tower crane
- 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:Who do you think was better and who would've won if they faced.
- Gotta go with Willie. The only match I ever saw Mosconi play was in Chicago back in 1964. He was down 46 to 14 going to 150. When he got to the table he ran 136 and out for the win. It was incredible. I never saw Crane in person and saw only one film of him. He ran 150 and out on Cowboy Jimmy Moore. A good friend of mine was telling me a story about the time he was in Johnston City, Illinois. Richie Lawrence was at the table. My friend was seated in front of Crane. As Richie was shooting, Irving Crane was telling his friend what Richie should be shooting every shot. Richie did just the opposite every time. The neat part about it was... Richie ran 150 and out... and never shot the right ball. Gotta give Willie the edge. Good question.
- Q:How do cranes use geometry?
- If your referring to cranes in construction cranes, then it might form a right triangle with the ground implying the use of trigonometry which is a part of geometry.
- Q:Equipment safety of tower crane
- The boom of a tower crane is divided into two types: horizontal and compressed arms. When the movable arm is horizontal, the carrier car runs along the horizontal arm with variable amplitude and amplitude, and the movable arm is longer, but the boom has a larger deadweight. The arm for the strut type when the tractor boom luffing mechanism pitch amplitude, amplitude motion than horizontal smooth, but its relatively small weight.The weight of a tower crane varies with its amplitude. The product of the weight and the amplitude is called the load torque, which is the main technical parameter of the crane. Through the rotary mechanism and slewing tower crane, lifting height, rotation and walking the inertial mass, so it needs to have good control performance, especially the lifting mechanism can fast, slow, heavy and light load installation fretting. In addition to the general use of resistance speed regulation, but also often use eddy current brake, FM, pole change, SCR and mechanical and electrical joint speed regulation. When the crane in the layout to drawing, especially in real estate development area, residential buildings, such as tower crane, but also to consider the safety distance of adjacent tower crane, two in horizontal and vertical direction to ensure the safe distance of not less than 2m, the adjacent tower crane tower crane and interference can not occur. Try to ensure that the tower crane in the wind is too large to be free of rotation. The safe distance between the rear arm of tower crane and adjacent buildings shall be no less than 50cm. The safe distance between tower crane and power line meets the requirement.
- Q:are crane flies the most venomous insect in the world,or is this just an urban myth?
- This one is definitely a myth, one that has been applied to both crane flies and the arachnids known as daddy longlegs (more properly known as Opilionids, or harvestmen). A simple fact of their biology can put this to bed: the adults of many species of crane fly don't even have mouth parts--the adult form is used soley for reproduction, with no time for food acquisition. Essentially, they mate and die. Production of a highly toxic venom is extremely energetically costly, and when they have no ability to inject it into anything (not even for self defense), it makes no sense for a life strategy. Common sense and simple observation will also tell you that this isn't true. There are stories all the time telling of people who have died from killer bees, or snake bites, or black widows, but when's the last time you saw a news bit on a crane fly fatality? I mean, news outlets, not to mention Discovery Channel and Animal Planet, *live* on stuff like this--yet I've yet to see a special entitled Crane Flies: Nature's Perfect Assassin. ;)
