Q: I'm curious: It's lifted in sections I believe. Once they're at their intended vertical height they then start to construct horizontally. Bit like big boys Mechano (not sure if I spelled that correctly).

Q: I am doing uni coursework to design an ergonomic layout for an operator cab for a tower crane and so I need to list the required operator controls.Thanks!: There are only two control levers that are on a tower crane.There is one on either side of the seat called joy sticks the right side joy stick controls the hoist cable to go up and down pushed forward to go down and pulled back to hoist up.The left has four functions it controls the swing of the crane and also the boom of the crane to control the swing you push the lever to the left to swing left and push the lever right to swing right.You pull the lever back to boom up and puh it forward to boom down.

Q: when a tall building is under construction you alwase see cranes on top. well i would like to know 1. how they move them up as the buildung gets taller and 2nd after there done how do they get them down?: bigger cranes

Q: im so frustrated because ive tryed everything and im obsessed with this book it would really help if someone could find a way for me to read it for free online. i cant find it at my library.please and thank you:)?: Shelly Crane is not giving the book away for free so any online site that has it, has stolen intellectual property.

Q: We need to purchase spare parts. If there are any supplier in the ASEAN region as possible. We are in urgent need . We are from Viet NamThank you.Email : tuanhuynh62@yahoo,com: they claim to have what you need. Good luck, I bet it's near impossable to get parts over there. You have a lot of work?

Q: Which style of Kung Fu has an animal system besides Shaolin? Which one has the Tiger, Monkey, Mantis, Snake, and Crane animals (not Shaolin because Shaolin has Dragon, Tiger, Leopard, Snake, and Crane.): Monkey Vs Snake

Q: Form the movie Dreamer, daughter of Ben Crane: It was Dakota Fanning that played Cale Crane, daughter of Ben Crane in the film Dreamer: Inspired by a True Story. She's a good little actress. I love to watch her films.

Q: Construction tower crane driver (T) Ben can be used as construction crane driver (S)?: Building crane driver (T); tower crane driverConstruction crane drivers (S); construction elevator drivers; neither is common.

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: Emergency treatment of interrupted electricity during lifting of tower crane: It is very dangerous to stop the electricity during the lifting of tower crane. Because the slewing brake is missing, the tower crane is very dangerous because the wind rotates.
