How does a home elevator cost?

Generally speaking,there are three main types of elevators.
The first is hydraulic. It takes up quite a bit of space in your home and requires a machine room for the equipment that runs the elevator. If your home is a new construction, then it is a little easier to plan the space needed for that type of home elevator. 

I like the way the designer used paneling and a gorgeous wood door to blend this elevator in with the home's decor. A modern convenience doesn't have to look out of place in a traditional space.

The second type of elevator is referred to as a traction elevator or machine roomless elevator,  and as the name implies, it does not need a separate machine room. It works by sliding up and down a track with a counterweight. If you are retrofitting, then this type is a better bet. It still needs additional space above the top of the elevator to house the equipment that runs it.

Although you don't have to build a shaft, so this is a pretty easy thing to install, you do need to have wide enough doorways to get the tube into your house. It requires a 39-inch-wide opening to go through, and most doorways are about 36 inches or less.

So how much does an home elevator cost? 

Well, that's a tricky question. As you can see there are a few kinds, and it makes a difference if you are putting one in during new construction or if you are retrofitting an existing space. The actual elevator itself can run $15,000 to $25,000, which doesn't include the cost of building a shaft or a machine room or running electrical.
The cost is also affected by the number of floors served and the options you choose. You could go with a very small, simple style, as in the photo above, or ...... you can opt for rich wood paneling, stone, mosaic, mirrors, grab bars oh, and let's not forget elevator music. Yes, some of these come with the ability to pipe in music. 


Another important add-on is a telephone. Since we don't always carry our cell phones around with us when we are at home, I think any elevator should include a phone for emergencies.

Elevator Design

Elevator Design

Some people argue that elevators as simple rope or chain hoists.

An elevator is essentially a platform that is either pulled or pushed up by a mechanical means. A modern commercial elevator consists of a cab (also called a "cage", "carriage" or "car") mounted on a platform within an enclosed space called a shaft or sometimes a "Hoist way". In the past, elevator drive mechanisms were powered by steam and water hydraulic pistons or by hand. In a "traction" elevator, cars are pulled up by means of rolling steel ropes over a deeply grooved pulley, commonly called a sheave in the industry. The weight of the car is balanced by a counterweight. Sometimes two elevators are built so that their cars always move synchronously in opposite directions, and are each others counterweight.
The friction between the ropes and the pulley furnishes the traction which gives this type of elevator its name.


Hydraulic elevators use the principles of hydraulics (in the sense of hydraulic power) to pressurize an above ground or in-ground piston to raise and lower the car . Roped hydraulics use a combination of both ropes and hydraulic power to raise and lower cars. Recent innovations include permanent magnet motors, machine room-less rail mounted gear less machines, and microprocessor controls.

The technology used in new installations depends on a variety of factors. Hydraulic elevators are cheaper, but installing cylinders greater than a certain length becomes impractical for very-high lift hoist-way. For buildings of much over seven floors, traction elevators must be employed instead. Hydraulic elevators are usually slower than traction elevators.

Elevators are a candidate for mass customization. How about one normal elevator cost?There are economies to be made from mass production of the components, but each building comes with its own requirements like different number of floors, dimensions of the well and usage patterns.So the elevator cost will be different,based on all the sizes and elevator design.

Elevator doors

Elevator doors protect riders from falling into the shaft. The most common configuration is to have two panels that meet in the middle, and slide open laterally. In a cascading telescopic configuration (potentially allowing wider entryways within limited space), the doors roll on independent tracks so that while open, they are tucked behind one another, and while closed, they form cascading layers on one side. This can be configured so that two sets of such cascading doors operate like the center opening doors described above, allowing for a very wide elevator cab. In less expensive installations the elevator can also use one large "slab" door: a single panel door the width of the doorway that opens to the left or right laterally. Some buildings have elevators with the single door on the shaft way, and double cascading doors on the cab.


Machine room-less (MRL) elevators

The entire drive system is in the hoist-way.
Machine roomless elevators are designed so that most of the components fit within the shaft containing the elevator car; and a small cabinet houses the elevator controller. Other than the machinery being in the hoist way, the equipment is similar to a normal traction or hole-less hydraulic elevator. The benefits are:
1.Creates more usable space
2.Use less energy (70-80% less than standard hydraulic elevators)
3.Uses no oil (assuming it is a traction elevator)
4.All components are above ground similar to roped hydraulic type elevators (this takes away the environmental concern that was created by the hydraulic cylinder on direct hydraulic type elevators being stored underground)
5.Slightly lower cost than other elevators; significantly so for the hydraulic MRL elevator.
6.Can operate at faster speeds than hydraulics but not normal traction units.

Escalator in shopping mall

An escalator is a type of vertical transportation in the form of a moving staircase – a conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individually linked steps that move up or down on tracks, allowing the step treads to remain horizontal.Escalators are used around the world to move pedestrian traffic in places where elevators would be impractical.Principal areas of usage include department storesshopping mallsairportstransit systems,convention centershotelsarenasstadiums, and public buildings.
Escalators have the capacity to move large numbers of people, and they can be placed in the same physical space as a staircase. They have no waiting interval (except during very heavy traffic), they can be used to guide people toward main exits or special exhibits, and they may be weatherproofed for outdoor use. A non-functioning escalator can function as a normal staircase, whereas many other conveyances become useless when they break down.

Design and safety


Escalators, like moving walkways, are often powered by constant-speed alternating current motors and move at approximately 0.3–0.6 meters (1–2 ft) per second. The typical angle of inclination of an escalator to the horizontal floor level is 30 degrees with a standard rise up to about 18 meters (60 ft). Modern escalators have single-piece aluminum or stainless steel steps that move on a system of tracks in a continuous loop.
Escalators have three typical configuration options: parallel (up and down escalators side by side or separated by a distance, seen often in metro stations and multilevel motion picture theaters), crisscross(minimizes space requirements by "stacking" escalators that go in one direction, frequently used in department stores or shopping centers), and multiple parallel (two or more escalators together that travel in one direction next to one or two escalators in the same bank that travel in the other direction).
As a safety measure, escalators are required to have moving handrails that keep pace with the movement of the steps. This helps riders steady themselves, especially when stepping onto the moving stairs. Occasionally, a handrail will move at a slightly different speed from the steps, causing it to "creep" slowly forward or backward relative to the steps. The loss of synchronization between handrail and step speed can result from slippage and wear.
The direction of escalator movement (up or down) can be permanently set, or be controlled by personnel according to the predominant flow of the crowd, or be controlled automatically. In some setups, direction is controlled automatically by whoever arrives first, whether at the bottom or at the top (the system is programmed so that the direction is not reversed while a passenger is on the escalator).

Safety



Safety is a major concern in escalator design. In India, where women wear saris, there are heavy chances of getting the pally entangled in the escalator. As a result, a special sari guard is built into most escalators.
There is a risk of foot injuries for children wearing footwear such as crocs and 
flip-flops that might get caught in escalator mechanism.This was due to the softness of the shoe's material combined with the smaller size of children's feet.
Fire protection of an escalator may be provided by adding automatic fire detection and suppression systems inside the dust collection and engineer pit, in addition to any water sprinkler system installed in the ceiling. To limit the danger caused by overheating, ventilation for the spaces that contain the motors and gears must be provided, and small targeted clean agent automatic extinguishing systems can be installed in these areas. Fire protection of an escalator floor opening may be provided by adding automatic sprinklers or fireproof shutters to the opening, or by escalator installation in an enclosed fire-protected hall.

What is Fireman’s elevator?

Firemans elevator is a type of passenger elevator which enables firefighters to use in order to rescue people who may be trapped on upper floors during an event of fire in the building.Firemans elevators are typically a normal passenger or service/freight elevators,and they have the firemans service mode activated by a key-switch or a toggle switch.
Firemans elevator is identified by a sign or mark says FIREMENT LIFT,FIREMANS LIFT,FIREMANS ELEVATORS or FIRE LIFT.
In Australia,some firemans elevators have a elevator design to allow passengers to use them as part of fire evacuation procedures.They are known as Protected elevators,and have to meet extra standards and reinforcement to keep passengers safe in an emergency.


Requirement for firemans elevator
1.At least 680ks(9 persons) capacity.
2.At least 1.1m width and 1.2m depth of the car.
3.At least 800mm width and 2m height for doors.
4.Elevator doors must be automatic closed.
5.Any doors and gates locked with key is prohibited unless they can unlock when the firemans service mode active.
6.Only 3 firemans elevators or less can be accommodated in the same shaft and cannot accommodate any normal commercial elevators.(Which cannot active the firemans service mode).
7.Two power supply is needed,normal and emergency power generator.
8.Firemans elevator must be finished in whole trip within one minute.

How it works
1.Active by a key-switch
Firemans elevator operates in two phases.In phase one,activated smoke detectors or hallway key-switches direct elevators to go to a fire recall floor.Elevators traveling away from this designated landing reverse direction and proceed without stopping.
Upon reaching the designated landing,passengers are able to exit the elevator and building safety.The elevators are then removed from normal service.Once removed from normal service,the elevators will no longer accept car or hall calls.
During phase two,once the elevator has reached its designated landing and all passengers are safety evacuated,firefighters can take exclusive control of the elevator equipment using a special service key-switch.This mode of fire service allows firefighters to continue to utilize the elevator for rescue people from other floors.


2.Active by a toggle switch
Firemans elevator operates in one phase only.If the toggle switch active,the designated firemans elevator will go to a fire recall floor.Elevators traveling away from this designated landing reverse direction and proceed without stopping.Upon reaching the designated landing,passengers are able to exit the elevator and building safely.The elevators are then removed from normal service.Once removed from normal service,the elevators will no longer accept hall calls.When the firefighters get in the elevator will dont need to use a special firefighters service key-switch because it already active by a toggle switch.This mode of Fire service allows firefighters to continue to utilize the elevator to rescue people form other floors because it will stop at the nearest floor by the firemen registered and call canceled automatically.
