Comprehensive Article for Elevator


Elevators or lifts, as they are commonly called, is a form of vertical transport used primarily to mover between multiple floors found in high-rises and skyscrapers. These are used to transport both people and goods from one floor to another. Elevators are also seen in large ships with multiple decks. In fact, today elevators have become a necessary addition to high-rises and other large buildings to make it easier for people with mobility issues to negotiate those using wheelchairs.

Basic principle

The basic principle behind the functioning of an elevator is the synchronized movement of traction cables and a corresponding counterweight system in opposite directions. Thus when the traction cables move up, the counterweights such as a hoist, etc., move in the opposite direction. This whole system is generally powered by either electric motors or a hydraulic fluid pump.

Elevator types

Most people are generally surprised to find that there are several types of elevators present in the market. But depending on the type of hoist mechanism used, elevators can be classified into 5 types which are generally used to meet the requirements of daily life. They are:

Traction elevators

Building Elevator

These elevators are generally used in high-rises and other large establishments, both for transporting people and freights.

These can further be classified into:

  • Geared traction elevators which use worm gears to facilitate and control the mechanical movement of the elevators and
  • Gearless traction elevators that use a drive sheave attached directly to one end of the motor and are generally low-speed elevators.
  • Hydraulic elevators:

These are less complex than the traction elevators and are hence ideal for low traffic or low-rise buildings and establishments. Using a hydraulic system, these elevators push the elevator car upwards against gravity while the car descends under the pull of gravity.

These are again classified into:

  • Conventional ones using an underground hydraulic cylinder to ferry passengers across 2 to 5 story buildings,
  • Hole-less ones which use cylinders placed above the ground and are extremely suitable for cost or environmentally sensitive buildings and
  • Roped ones that use both cylinders placed above the ground and ropes thereby enabling the elevator to travel much farther than the piston are able to move.
  • Climbing elevators: These are self-ascending and use their own propulsion to ascend. This propulsion can either be achieved by combustion or electric engine. These types of elevators are generally used in towers or guyed masts so as to facilitate easy access for the maintenance of different parts of the constructed structure.

Pneumatic elevator

Building Lift

As the name suggests these elevators use a vacuum and a valve to move the car upwards and air in place of the vacuum to move it down. These are, however, low capacity elevators wherein only about 3 passengers with a combined weight of 525pounds can get on it at the same time.

Electromagnetic propulsion elevators:

These cable-free elevators use electromagnetic propulsion to move the car which can mover both horizontally and vertically. They are generally used in high-density high-rises.
The discovery of the elevator was of great advantage to mankind since it enabled the movement of passengers and goods between different levels of a building without incurring any physical strain. It still remains an extremely functional device to date.

The need for Residential Elevator

The primary reason for having a residential elevator system is mobility. But it can also increase the value of your home. For members of the family who have reduced mobility, like the elderly and the physically disabled. Residential elevators render a valuable service by letting them save time or even allowing them to do certain things. That would not have been possible if the home only had stairs as the mode of access to the various floors. Obviously, the more floors your home has, the stronger the need for a residential elevator system.

A Residential Elevator, A Necessity or A Luxury

Commercial Elevators

Many homeowners would hesitate to install a residential elevator system because it is supposedly expensive. However, if there are physically disabled and/or elderly members of the family. Residential elevators are no longer a luxury, but a necessity. For people who are in their golden years, the stairs have also become dangerous for them. Because of the higher possibility for accidental falls. And for the other members of the family, home elevators can make it much easier. More comfortable and more convenient to transport heavy items to other parts of the home.

The Space Required For These Elevators

If you are worried that it will take too much space, think again. Because its size is like that of a closet and there are self-contained units. That does not require a separate machine room, a pit, or hoistway. These kinds of units do not require drastic structural changes to the home, thus minimizing expenses during installation. You can also opt for exterior mount models to further reduce the effect on the home structure.

Investing In A Residential Elevator Sooner Than Later

Commercial Lift

When planning a new home, it may be advisable to consider the possibility of adding a personal elevator either at the onset or later on when the husband and wife enter their golden years. As people age, they become more and more reluctant to climb the stairs. That is why empty nesters often move to the first floor of a multi-story home or even transfer to a single-story home.

  • A single-story house is actually more expensive to build than the two-story house for the same square footage.
  • Young couples often choose a two-story home but shift to a single-story home after their children have married and bought their own houses.
  • This could be avoided by including the possible use of an elevator in the construction plans.

If the couple does not have the budget to purchase it yet, they could use the space allocated for the system as a place for closets or cabinets. And when they attain their golden years, it would be much easier to install with minimal changes to the home structure.

With the provision for the placement of a residential elevator available, elderly couples need not transfer to the first floor or find a single-story home. If you think about it, this particular machine may not be that expensive after all if you consider the benefit of continuing to live in the house that you have learned to love. Aside from that, your home may command a higher price in the market due to an increase in property value.

The hydraulic elevators may be preferable to the conventional hydraulic elevator that requires a pit for the placement of its pair of hydraulic jacks. This arrangement is suitable as a residential elevator for buildings that have two, three, or four floors.
While there are other benefits provided by the hydraulic elevator, it is mainly used for homes where there is a possibility that the soil or groundwater may be contaminated when the conventional design is used.

The Contamination

The reason for the possible contamination is the leakage of oil used in the jacks due to electrolysis and corrosion in the metal parts of the jacks themselves. Thus, if the condition of the soil is such that it allows the seepage of the contaminants, the hydraulic elevator is a possible solution for the home with up to four floors.
If possible contamination is a worry for you then hydraulic elevators might be the solution.

Advantages of Hydraulic Elevator Elevators

Another advantage of a hydraulic elevator for home elevators is that it requires less expensive because there is no need to dig a pit to provide a space for the pair of hydraulic jacks.
Another benefit is that jack replacement is much easier because it is located above ground. Corollary to this, maintenance is also less expensive and easier to perform.

The Roped System

However, for the residential buildings where the number of floors is higher than four, the hydraulic jack design has to be assisted by a rope system. The roped hydraulic elevator is applicable for up to 10 floors. It retains the advantage of the holeless design because the jacks are still above ground.
It has a plunger on both sides of the car and a sheave that is regulated by plunger guides. The ropes are attached to the bottom of the car and to the top parts of the jack stands. For safety, this system slows down a dropping car by using a governor tension sheave and a traction governor.
Meanwhile, residential hydraulic elevators in general offer the advantage of assisting the elderly in their mobility requirements. While these are quite expensive, they are essential for households with members who are either physically disable or are in their golden years.

Hydraulic Elevator Example

However, it is also important to consider less costly alternatives. For example
If the purpose is to aid the elderly in climbing the stairs for a two-story or three-story home. A stairlift, or even used stairlifts, may be less expensive both in the initial outlay and in maintenance.
And if the intention is for lifting objects, such as food and other materials instead of people. A dumbwaiter may be the better choice, again, because of lower expenses.

The Conclusion

The hydraulic elevators are the possible choice for those situations when the soil permits the seepage of the oil from the hydraulic jacks that may result in contamination of groundwater. Of course, there are other alternatives that prevent such contamination.

  1. The pneumatic elevator does not require hydraulic jacks nor does it require a pit.
  2. The gearless or geared traction elevator. Which is power by an electric motor where the safety provision against power failure? Breakage of the cable is a brake that is automatically activated when there is a loss of power.
