Kone Roped Hydraulic Glass Elevator at High Museum Atlanta

[stealthstahl]

In the trade these are often called a holeless hydro, because there's nothing that extends below the pit structure. In San Diego there's a sternwheeler at the Bahia Resort that has a holeless hydro in it. With a conventional hydro the piston would have to extend through the hull below the elevator.

Nice elevator. Btw, the Renzo Piano addition was built in 2002. One of our Wentworth graduates actually worked with Renzo Piano on this project. The original structure was by Richard Meier. Both are absolutely stunning examples of post-modernist architecture.They couldn't have picked a better architect to match Meier's masterpiece.

not sure!

Not a bed retake.

boring you geek

[musicfreakcc]

Well, I guess our interests differ. If you find my videos boring, don't watch them.

Hydraulic elevators use hydraulic fluids, a motor/pump, pistons and jacks. In a classic in-ground, the motor pumps the fluid out of a resevior and into the cylindar raising the car. Hole-less elevators do this aswell, except the piston is above ground. Roped hydraulics work by having a piston and jack above ground move a pulley upwards, therefore lifting/lowering the elevator. It does this in a 2/1 ration, so for every foot the piston moves, the car moves 2.

musicfreakcc is right. do some research on google and you will see what we are talking about.

Sorry but what is the differents between tracion and hydronic

[musicfreakcc]

Google it.

Hydraulic elevators use 1 of 4 methods: Holed hydraulic, roped holeless hydraulic, holeless hydraulic and telescoping holeless hydraulic. In a hydraulic elevator, it pumps hydraulic oil into the hydraulic jacks and makes it go up. On the down trip, the hydraulic oil is released back into the pump to make it go down. Holed hydraulic are very pollutive because the oil can leak into the environment. That big pole on the bottom of the car is the hydraulic ram.

A traction elevator on the other hand does not used hydraulics. There are 3 methods for this: gearless traction, geared traction and MRL gearless traction. MRL stands for Machine-Room-Less. Instead, a small closet for the controller is placed at the top landing. A traction elevator uses cables and a counterweight that is equivalent to 40% of the elevator's capacity. It doesn't use hydraulics. A geared traction uses a gearbox and has speeds for up to 500 feet per minute and rises up to 27 floors.

[Baytrail]

A gearless traction does not use a gearbox that weighs the elevator down and has speeds above 500 FPM and up to 1600 and beyond. An MRL elevator is always gearless and runs at speeds of up to 500 FPM. They are beginning to become cheaper than hydraulics and will eventually replace them. So you might be wondering: If gearboxes weigh elevators down, why do they used them? My answer: It's weird, but I have NO clue. So there you have it ahocknul04.

Traction elevators use a motor and ropes basically, a pulley system. The most common types are gearless, geared, and bottom drive.

@ahocknul04 Hydraulic is a type of elevator that has something below it, which means it pushes it up, and pulls down. Traction is a type of elevator that runs on cables.

Very stylish.

[Neuroth52489]

It sounded like the Fire Alarm Was on.

[Baytrail]

Musicfreakcc, sorry for giving you a little extra work, but I wanted to respond with a video, but I linked it to the wrong one. It's starts with, "? Elevator...". Disprove the first link, and accept the second.

[escalatorgeek881]

Where was the alarm from on SR?

[musicfreakcc]

That was a car alarm.

[Neuroth52489]

Well it appears its beutiful in atlanta BUT NOT HERE! :(

[Ih8escalators]

Cause I know a fire alarm panel that sounds like that.

[Ih8escalators]

Did i hear a fire alarm panel on SR?

[musicfreakcc]

That was a car alarm.

I didn't know Kone made roped hydraulic elevators, but it's sad to see even the above ground holeless & roped elevators be discontinued. However, I like traction elevators more, since they're energy efficient, use no oil, travel faster, and are more reliable.

[musicfreakcc]

Yep - those ones were made right before Kone stopped making hydraulic elevators,

[CaptainElevator42189]

I know, but I like traction elevators more.
