Q:Breifly explain the brake system in the lifting devices ex. Over head crane?
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:In designing an overhead travelling crane what are the engineering limits on lift capacity .?
Is this for a nuclear power station? If 2500 Te and 60m really are the specified loads and span then it is likely that it will be used very seldom. In theory you can design for any load to be lifted but maintenance on a crane system that is used once a year (10 years?) is a real problem. The main items to consider are: Availability of winches and bogies which then dictates running beam and rail sizes. For the spanning beam several alternative sizes needed to be designed and then costed. It will be not just weight but transport costs that determine the most efficient sizes The overall height of the crane will then determine the required roof height assuming that the crane is under cover. For comparison the Harland and Wolf cranes in Belfast called Samson and Goliath can lift 840 Tonnes each. Overall design needs to consider speed of travel, acceleration and deceleration rates and a host of other things.
Q:What should be included in the disassembly plan of the tower crane?

Q:Crane Style Kung-Fu?
look man to learn the 5 animals stuff, u can't do it by urself !! u need reflex and you can't have it unless some1 teaches you some techniques !! well actually i wanted to learn Kung fu so i started learning it from the internet !! well there is a time i thought that i new almost everythng and was perfect at it ((that was how i saw myself !!)) but when i got into a Kung fu club i coudn't keep up with them !! so if you want to learn the real techniques you should go to a school or something !!!
Q:Tower crane 5610 why call QTZ63 tower crane, 5613 call QTZ806015, call QTZ100
The type of "QTZ100" indicates the hoisting tower crane with nominal lifting torque up to 1000KN.m;5610, 5613, 6015 and so on model meaning is, the first 2 digits indicate effective variable amplitude length, the unit is m, and the latter 2 for the largest amplitude of gravity, the unit is KN.These two models do not have any objections, can be converted, not the latter way of expression is more reasonable, and by the current domestic manufacturers widely used.TC5610 nominal lifting torque to 630KN.m, but not up to 800KN.m, so it should be considered QTZ63 series.TC5613 nominal lifting torque reached 800KN.m, but not 1000KN.m, so divided into the QTZ80 series.TC6015 nominal lifting torque reaches 1000KN.m, so it is divided into QTZ100 series.
Q:How much height should tower crane work at M?
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:How much is an origami crane and other models?
Since the crane is such a basic figure, and anybody who's interested in origami can make it for themselves, you probably couldn't sell them. Maybe you might be able to sell some of the more complicated models, but I can't think you'd get much for them. There's no market.
Q:Blue Heron, Crane, or Egret?
ive seen blue herons here in maine they are garyish with long legs and beeks they stand very still so they can catch there food with long beeks
Q:Hunger Games Question: Why is Seneca Crane important enough to be in the movie?
Seneca Crane was the game maker of the 74th hunger games and let two tributes win aka Katniss and Peeta. Seneca Crane was the executed because of that because the capitol felt like having two tributes win was a defeat for the capitol because it showed that the capitol lost control and therefore can't completely control everything..which was what all districts were used to at the time, or at least until Katniss and Peeta 'rebelled'. From a film aspect, Seneca Crane is important because they might use him to advance the plot and Crane might also be a huge transition piece from the first movie to the next (since he was kind of the reason for fueling the flames of the rebellion). I LOVED Madge too, and I am not entirely sure why they left her out, though she seemed important in the book she really wasn't. She only gave the symbol of the rebellion and helped Katinss here and there, but she wasn't really a plot advancing character...I mean anyone could have helped Katniss and given her the mockingjay...most likely Cina will be giving her the pin in the movie because he is Katniss' stylist. TEAM PEETA RULES!!!!!!!
Q:Is there a crane lifting chart where I can enter info. to determine what size crane I need, if so where?
Sorry, it's not quite that simple.
