Q:What kind of force acting in the brake system which encounter the lifting material force and to maintain its level.
Cranes work using hydraulics and cables. The cables are wrapped around pulleys and the pulley is turned using hydraulic power. The brake system is simply stopping the pulley from turning by reducing power. The hydraulic system typically will turn a series of gears which in turn spins the pulley that the cable is wrapped around. It's different than a brake system say on a car where when you hit the brakes, pads squeeze on the interior of the wheel rim slowing it down. Cranes you just reduce power and stop the pulley from turning. They also have emergency stops. Older cranes have wedges that would be released onto the cable and then the wedges would grab the cable and slip into a ring. The narrow end of the wedges would slip into the ring first and then as the wedges increased in diameter the grip on the cable would get tighter and then stop the cable from moving. They also have systems on the pulleys to stop the pulley from spinning. They essentially work the same way as a car break. When the emergency brake is triggered, pads will squeeze on the rim of the pulley to stop it. These mechanisms work by friction. They could also have holes around the pulley and a steel pin would be pushed into one of the holes to stop it from spinning. Of course if the force of the weight exceeded the strength of the pin, it would shear.
Q:My dad has some old tools and he is wondering if the company is still around, or what happened to it. A yahoo search revealed little.
Found on - www.lathes .uk/boicecrane/ Boice-Crane - USA Boice-Crane (Wilton Division) made various types of power tools, including a selection of wood lathes intended for amateur and educational use, and in the 1940s and early 1950 their range included, amongst others, the two amateur and one professional or educational machines illustrated below. The more robust lathe of the amateur pair had a 50 inch long bed with 10 swing and able to take 34 between centres; the 4-step V pulley in the headstock could be driven from either from the rear, or underneath. The bed, which had a gap able to swing 14, was internally ribbed and machined on its top surface. The No. 1 Morse taper tailstock was fitted with self eject for the centre. The double-ended spindle was 1.25 inches in diameter and ran on ball bearings - whilst the single faceplate contained two different diameter, left and right-hand threads so that it could be screwed onto either end. The lathe weighed 115 lbs, so, despite an insubstantial appearance, must have been a reasonably robust machine. The other bench lathe had a bed built from two steel channel sections - with the most elementary type of headstock and tailstock. The capacity was 10 x 30, the weight 30 lbs and the headstock spindle carried a 4-step, overhung, V-belt pulley. The company are now: Gothenburg Manufacturing Co., P.O.

Q:Write a fully developed paragraph that contrasts the effects of war in two of the following works: Cranes, Thoughts of Hanoi, and Tokyo.
I could not find Tokyo on the internet...I will look for it later because the first two selections were so good. I did find and read Cranes and Thoughts of Hanoi. The thing that struck me most was that they both had in the back of their minds, in their memories, the thoughts of childhood in their home countries, all its mysteries and beauties...and as well all the regular, daily life going-ons of the communities. It was all still alive to them in their mind, and indeed, in real life. Those same trees they climbed as children still grew. farmers still grew crops. Birds were still birds, wild and free, or caught and sold. War is so awful, so much death, I think you are astonished to find that life still goes on. Much changes yet much remains unchanged. The great wheel of life turns.
Q:Since a crane has to extend outriggers while performing lifting operation , is it ok to allow a crane to transfer materials by carrying without extending outriggers and lifting and carrying load to different location especially in construction industry for safety reasons?
Yes, this is not only possible, it is done by cranes that are designed to operate without outriggers. There is a company called Lampson that has a whole product line of these cranes (see link). I have personally witnessed a number of lifts where an outrigger-less mobile Lampson crane moved a load in the multi-hundreds of tons during construction of a nuclear power plant.
Q:Trying to find an estimated weight for a mobiles crane with a 5 tonne capacity ?
It is not the weight of the crane alone that matters. But to some extend if the crane is light, this could create a torque when carrying a heavy load and the crane could collapse. Therefore I am speculating that inorder to lift 5Tonnes, the crane must be more than 5 tonnes to balance out the moments resulting in a torque The internal structure of bolts and trusses must be able to handle heavy loads and their are several calculations done to find each forces acting on the members of a truss. For eg: By using Pin Joint Analysis
Q:Hi! I'm only going into 9th grade, but I'm getting a head start on chooising a college. I am absaloutley positive I want to be a musician. Hopefully a singer/songwriter, but my plan B is music production. So, I'm going to put Juliard aside (lol)and here are my choices right now:Crane School of Music,Fredonia School of Music,and Berklee School of Musicplease give me your opinion on those schools, and if you could suggest any others, please do. I need all the information I can get...Ive been doing alot of research but now I need other people's opinions. thanks :)
Fredonia School Of Music
Q:I am looking for what the breeding season is for sandhill cranes?
Mid-April to mid-June is breeding season for Florida Sandhill cranes lasts from December-June. For most other cranes, like those here in the midwestern U.S., the breeding season is March and April. I'm fortunate enough to live not too far from the Jasper Pulaski Fish and Wildlife Area where the Sandhill Cranes migrate every spring and fall. I always go to see this spectacular event.
Q:You know those machines you pay and get like 15 seconds to operate the fricken metal hand?Can you give me some tips?
make sure you find something that isn't trapped by anything else in the pit.. line up the crane one the front, then move over to the side and line it up... these machines used to be a lot easier 20 years ago, but now the arm doesn't apply much pressure.. it has to be lined up just right or you will never get anything...
Q:WHAT IS A WADDLE CRANE?
Well okorder / but I couldn't find any reference to them being called waddle cranes. While the W on a key board is close to the S, you'd have to miss the TR for waddle to be misspelling of straddle, so I have no idea, sorry.
Q:Which is the main basis for the disassembly and assembly process planning of tower cranes?
.0.11 tower cranes should be prepared before the installation of special construction program, and should include the following contents:1 project overview;2 installation location, plane and elevation;3 types of tower cranes and technical parameters of performance;4 basic and attachment device settings;5, climbing conditions and adhesion nodes detail;6 installation sequence and safety quality requirements;7 weight and suspension position of main mounting parts;8 installation of auxiliary equipment type, performance and layout;9 power settings;10 construction personnel allocation;11 rigging and special tools;
