Types of Elevator
An elevator or a lift is a type of vertical transport device that efficiently moves goods or passengers between floors of home or office buildings, hospitals, commercial and industrial places, airports, vessels, schools and other constructions. Many kind of elevators can be used in all over the world for different purpose.
Elevator types are divided into four;
2. Traction Elevators;
3. Pneumatic Elevators;
4. Climbing elevators.
In today’s world, traction and hydraulic elevators are used more than the other two. Elevators have different dimensions and drive units according to building type and number of passenger or load of goods in it. Increasing the load weight increase the cabin weight and area. The most widely used lift type is machine-roomless. This type of elevator is more economical and more useful for vertical transport.
Hydraulic elevators can be used in places up to about 1-3 stories because of their lower setup cost. Geared Traction Elevators can be preferred for Mid-Rise buildings up to about 4 to 11 stories. For places up to about 12 or more than 12 stories (High-Rise buildings), Gear-Less Traction Elevators are preferred. In some of the lift project like as for luxury hotels, speed of the elevator is the most important expectation. Increasing the speed of the lift increase the cost of the elevator. Moreover, stairways elevators are used for disability people both inside and outside the home. They can be work in an around a curved stairway or straight line and they run on a rail up and down. The other solution for disability passengers used wheelchair is wheelchair elevators. This type of elevators generally works from 1 to 2 meters. Vertical wheelchair elevators work with a platform can easily be installed when space is limited. As a result, all kinds of elevators are designed by engineers to make life easier for people.
