Bailong Elevator is the highest and heaviest outdoor elevator in the world...

In the 1800's, new iron and steel production processes revolutionized the world of construction. With sturdy metal beams as their building blocks, architects and engineers could erect monumental skyscrapers hundreds of feet in the air.
But these towers would have been basically unusable if it weren't for another technological innovation that came along around the same time. Modern elevators are the crucial element that makes it practical to live and work dozens of stories above ground. High-rise cities like New York absolutely depend on elevators. Even in smaller Multistory buildings, elevators are essential for making offices and apartments accessible to handicapped people.
In this article, we'll find out how these ubiquitous machines move you from floor to floor. We'll also look at the control systems that decide where the elevator goes and the safety systems that prevent catastrophes.

Types of Elevator: 


Conventional Hydraulic Passenger Elevator : 
An in-ground jack lifts a platform that is guided by rails. The hole is usually drilled before the building is erected. Inside drilling can be arranged for special situations. Mechanically, this is the most balanced hydraulic elevator configuration since the lifting point is centered on the load of the elevator car. 



Holeless Hydraulic Passenger Elevator : 
A cantilevered platform is lifted by a jack that runs between the guide rails. This configuration cannot have rear entrances. 



Holeless Dual Cylinder Passenger Elevator : 
Two cylinders situated beside the rails lift a platform guided on the rails. This configuration can have front and rear entrances. The maximum travel is 4500 mm. Oil noise is greater than an in-ground 



Roped Hydraulic Passenger Elevator : 
A cantilevered platform is lifted by ropes that pass over a sheave fastened to the top of a hydraulic jack. This configuration cannot have rear entrances. 



Geared Traction Passenger Elevator : 
A conventional overhead geared machine with the car attached to cables that are counter-weighted over the drive sheave. The motor size and power consumption is significantly lower than hydraulic elevators, but the elevator and building costs are higher. 



Enclosed Vertical Wheelchair Lifts (Accessibility Lift): 
A budget-priced lift that meets all applicable codes. It is available is several different cab configurations and cab colours. 



Conventional Hydraulic Freight Elevator : 
An in-ground hydraulic jack lifts a platform that is guided by rails. These durable units stand up well to rough loading conditions including forklifts and tow motors. Most freight elevator sizes are custom designed to suit the loads being lifted. 



Freight Platform Lift (FPL) (Material Lift) : 
A more economical way to move freight (5000 mm maximum). These lifts can only penetrate one floor and may carry only one operator. The swing door systems are typically not as durable as in freight elevators.





The Bailong Elevator - The Bailong Elevator (literally Hundred Dragons Elevator) is a glass elevator built onto the side of a huge cliff in the Wulingyuan area of Zhangjiajie, China that is 1,070 feet (330 m) high. It is claimed to be the highest and heaviest outdoor elevator in the world.
