How do capsule elevators differ from ordinary lifts?
Inorder to understand the concept of capsule lifts; we need to first understand the technical meaning of the word lift. Simply put, a lift is a device which is used to transport people and things vertically up a building between its different floors, levels and decks. It is generally built in the form of a cab within an enclosed space called the shaft. A deeply grooved pulley or sheave is used to roll steel ropes thereby facilitating the upwards and downward movement of the cab within the shaft.
While the basic principle of hoisting the lift remains the same, capsule lifts differ from ordinary lifts in their design. Capsule lifts are generally made of glass panels and may or may not be within a shaft, which even if present is made up of glass panels too. These lifts perform the dual function of both
- Carrying people vertically up and down a building and
- Enhance the beauty and aesthetics of the building where they are built.
The ability to look around and feel the distance from the ground onwards, itself, accounts for an awesome and breadth-taking experience.
Need for capsule lifts
Capsule lifts are generally fitted in residential or commercial high-rises primarily because
- They are compact units and require less space than ordinary lifts,
- They are adaptable enough to be fitted in any place on the building it meets the minimum safety requirements,
- They can be tailor made to suit the requirements of the customer and
- They add beauty and enhance the outlook of a building.
Capsule lifts can either be installed within the building facing the atrium or can be on the outer walls of the building. Those that are installed outside are known as scenic capsule lifts for they provide an outstanding view of the places around the building.
Capacity of capsule lifts
These elevators which enhance the prestige of a building by acting as architectural highlights are made in such a way that they are almost noiseless in their operation. This makes them ideal utilities for carrying people and hence come in varied capacities of 4, 6, 8 or even 20 passengers. In order to facilitate this transfer of up to 20passengers from one level to another, they have to come equipped
- With extremely efficient load bearing capacity,
- Be easy to operate and maintain and
- Be absolutely stable and operate smoothly.
These lifts also have to be made with extra precision as they are specialised devices which can be used for both residential and commercial purposes. Hence glass panels used have to be of superior quality which complies with the international standards and norms in terms of quality.
Operation of the capsule lift
Generally VVVF technology is used to operate capsule lifts. This type of lift drive uses the technology of frequency inverter to regulate the frequency and voltage of the electrical input at all times. Thus when the lift is in operation, it uses much less electricity both during its acceleration and subsequent deceleration. This makes these lifts energy efficient and helps to offset its initial cost of installation which is higher in comparison to that of a regular or ordinary lift.
The control panel used for the successful negotiation of the lift is microprocessor based which is extremely sensitive to touch and very elegant looking. Also the state-of-art technology that is used to enable the proper functioning of these lifts ensures that they remain low maintenance devices thereby further compensating for its initial high cost.
