Actually a sort of elevator lift home if they meet some criteria as follows:
- Size hoistway less than approximately 1.5 m x 1.5 m
- No need for engine room
- Requires a small electric power
Actually there is a system of more than two options above, the screw / nut system, which uses a system such as bolts with ulirnya.
Small children can use it (Not Reccomended)
The advantages are:
- The room is smaller (because not using the counterweight)
- If the power fails, do not fall
- Electrical power is small.
- Does not require the engine room / pit.
Indeed I still do not see whether there was installed in home, but it may be considered as an alternative to the existing home elevator.
