ELEVATORS - GIVING YOUR LIFE A LIFT
Raleigh, North Carolina. Home elevators. I received an email from a couple who are thinking about having an elevator installed in the home they are going to have built. Since more and more high end homes either have an elevator or have plans that provide for the installation of one later on, this is a good time to discuss them. Some are installed just for the sake of convenience (or perhaps to show off a little) while others provide a solution to very real need such as physical problems or getting heavy items from floor to floor. Typical home elevators range in price from around $13,000 to $30,000 while custom elevators can START at about $50,000. You can personalize the elevator cab with glass, match the wood used in your home, paint a mural, whatever you think goes well with the style of home being built and the interior woods and paints being used.
THINGS TO THINK ABOUT
COST - The cost varies and is based on size, cab finish, drive system and speed. WEIGHT CAPACITY - Capacity ranges from about 450 to 1,500 pounds. I think you should opt for one that can handle 900 to 1000 lbs. CAR SIZE - Common sizes are 36 x 48, 36 x 60, 40 x 54 and 42 x 60. You need to work this out with your plan designer/architect and/or builder. WARRANTY - Most companies offer a one-year warranty on materials and workmanship. You would do well to see if your builder will give you a one-year warranty on any installation work he does. SERVICE CONTRACT - Ask the company you are considering purchasing from if they offer a service contract for maintainance and what it covers. CODES - Forgive the vulgarity but CYA ALL THE WAY! Have your builder provide you with both the national and local codes that apply to residential elevators. A building permit is required prior to installation. You want to know what it says and you should go over it with your builder.
There are four types of residential elevators: Winding Drum, Traction, Hydraulic and Pneumatic. The two most commonly used are Winding Drum and Hydraulic. The Winding Drum has a set of cables attached to the car. Winding the cables in one direction lifts the car while unwinding lowers it. There is a backup battery that is used to lower the car in case of a disruption of power. Advantages of this system: (1) It has been around a long time and is a proven system. (2) No need for a separate room to house the machine (3) While it costs less than a hydraulic system, the battery backup makes the prices of the two systems about equal. Disadvantages of the system: (1) As many winding drum systems have the motor in the shaft it can be noisy. (2) As the motor is in the shaft they are more difficult to repair. (3) A relatively large motor is needed to carry the weight of the car (4) Room is needed above, below or to the side of the elevator to house the motor and the back up battery.
Hydraulic Systems move an elevator by pumping oil in and out of a cylinder. The most used technology is cable hydraulic. The car in pulled up and down from above. In this system the motor (which is a pump) in only needed for the up direction. Gravity is used for the down direction. For power outages a battery is needed but a smaller one than is needed for the winding drum system because gravity takes care of most of what is needed to lower the car. Advantages of the sytem: (1) - They provide a smoother ride. (2) - The motor doesn’t have to adjoin the car (3) - They are quieter because the motor is surrounded by oil which buffers the sound. (4) - It can be put in any temperature-controlled area away from the core living space. Disadvantages of the system: (1) A separate room is needed for the hydraulic pump and battery.
The kind (brand if you will) of elevator you get will usually depend on your builder, his local suppliers, and/or where it has to be ordered from.
