- Q: how is a tall crane constructed? how can they put the crane on top of its tall body frame?
- They first construct the top of crane on the ground with help from other mobile cranes. This includes the long horizontal part with the operator's cab, and the concrete counterweight. this is then placed on a climber, with which the crane kind of builds and climbs itself to the necessary height. Every vertical section of the crane is placed in the climber. When the piece is in place, the climber climbs to the top of piece from where the next vertical piece is placed and so on. You can see how a crane is constructed in the website I've cited below:
- Q: For those of you who know about the tradition where you make origami cranes and can make a wish, is it 999 cranes or 1,000 cranes? Cuz I just finished making 999, but I'm not sure if it's actually supposed to be a thousand instead.
- It is susposed to be 1000 cranes. You string them in 10 sets of 10 cranes. [thats how I remember!]Can you send me your way of folding them? I can't find one that works right for me, they always turn out a little wrong. :[
- Q: [tower crane] and [tower crane] what is the difference between, how to distinguish?
- To put it plainly is a great name.A nickname is.
- Q: How the cranes can stand without any tipping with huge counter weights on its back? If there is no suspended load also the crane is is still stable with huge counter weights on its back. How it can possible? Why crane is not offballencing while we adding extra counter weights on it without any suspended load?
- Usually the counterweights can move back and forth on an arm. They are moved toward the crane when there is no load and away from the crane when there is a load. If the counterweights can't move, then the crane must be designed to hold (at least) the minimum counterweights in their fixed location. As the crane gets loaded, the net moment decreases, and then increases in the other direction as more and more load gets added. It is still likely that the maximum design moment when loaded far exceeds the moment due to the counterweights on an unloaded crane.
- Q: I'm looking for estimate including installation, vertical support beams, and bus bars. Details: rectangular shaped building 500 ft long split lengthwise into two sections. 500ft X 4lengths of craneways is 2000ft. The crane runways are bolted to building frame but are self supporting on I-beams (104 vertical supporting beams X 24ft. height). The crane runways can support 10ton hoists. The bus bars (electrical conductor assembly) run along all (2000ft) of crane runways.
- the only 5'6 girl I know of who did runway was Devon Aoki. Everyone else is at least 5'9+ except Kate Moss who is 5'7.5. The average height for runway is 5'10
- Q: Do large semi-submersible crane vessels such as the SSCV Thialf propel themselves to work sites or are they carried on heavy-lift ships. I understand they have propulsion systems but the just seem so bulky, inefficient, and slow to move across oceans on their own.
- Very large capacity crane vessels have propulsion machinery for manoeuvring when on station. The most modern designs of semi-submersible vessel use them to achieve 'dynamic positioning'. Older designs used the propulsion systems to assist when deploying the anchors in the correct pattern. The vessels are towed by tugs when making deep sea passages. First generation crane vessels had much smaller lifting capacities and were either constructed on conventional hulls or were converted from existing ships. These types were capable of making ocean passages using their own propelling machinery.
- Q: He is one of my favorite poets. I want to read more of his work.
- How about my favorite poem about Hart Crane? AT HART CRANE’S TOMB by Glenn Robert Swetman In his mind’s dark, he spoke a frivolous age where marriage of the like was spring, where vitelline worlds of virgin instinct were crushed in the obscene cleanliness of a raccoon’s paw. Did he imagine that his great sun could come trailing yellow handkerchiefs of light, like a queer comet? No, there is something out there that commands, and not worlds of perfect clipping will turn these rotund hedges into maypoles—and live. That’s why the green expands as it reaches. He must have seen this finally. His leap Into the green sea was, aesthetically, clean.
- Q: Ty Crane is the star basketball player for st.francis, what is he doing now? Where is he? Why is he not in the NBA?
- Ty Crane was played by Sidney Faison full-time basketball player and part-time actor. When I last heard of him he was playing for the Magic Johnson Travelling All-Stars
- 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: Brief introduction of ten no hanging criterion for tower crane operation
- 4, buried objects do not pull the crane; 5, cable-stayed holding objects not hanging 6, the slings and objects; rickety bundle does not meet the safety requirements to crane; 7, vehicle weight hanging directly processed when not hanging;
