What Are The Different Home Elevator Drive Systems?

Installation of elevators in homes becomes a necessity especially if there are people staying in it who need assistance walking. This assistance might be for problems related to age, temporary inability to walk due to some accident or a more permanent disability. Whatever the reason be, today home elevators are being commonly installed.

Different drive systems of home elevators

Home elevators today come equipped majorly with five different types of drive systems. They are:

– Roped hydraulic drive: These are low maintenance elevators which is quite similar to its commercial counterpart. It thus uses a hydraulic piston and aircraft cables to enable the upward and downward movement of the same. some of its important features are:

->It needs a pit of about 6 to 8 inches to be installed as the hydraulic fluid used needs to have a submerged pump.

-> Its operation and both downward and upward rides are very smooth and almost soundless.

-> The maximum speed for travel in any home elevator is 40ft per minute. This drive system is easily able to achieve it.

-> It has a weight lifting capacity of about 1000pounds.

– Winding drum drive: The speciality of this type of elevator is that it uses a 3/8th inch aircraft cable to haul the lift up and down. It is assisted by a motor which can be mounted either at the top of the interconnected rails or behind them. The placement of the motor actually depends on the availability of space within the lift shaft. The variable speed generated by the motor helps to wind the cable around the drum present at the top of the rails to facilitate its ascent. While descending the weight of the car provides the required impetus for its descent.

– Counter weight chain drive: This type of drive system is unique because it uses weights to lift up the cable. This offsets the requirement of the powerful motors which generally form a part of the drive system. Instead a chain drive is used to lift the elevators while at the same time the weights get lowered thus creating an offset. The biggest advantage of this type of drive system is that it does not require space for a machine room. It is also an efficient yet low maintenance device which offers a good many benefits without compromising on the basic functionality of the elevators.

– Vacuum Drive: Known as PVE or pneumatic vacuum elevator, it is a relatively new, innovative and revolutionary concept that does away with the necessity of cables or chains and counterweights or pistons. It comprises of a tube shaped elevator cab placed in a hoist-way which is also shaped like a tube. The use of tight fitting parts is a crucial requirement of these elevators as they help to maintain precisely accurate atmospheric pressures both below the cab and above it. The cab is lifted up using turbines which create the necessary suction for its lifting while the release of pressure through the control valve enables it to come down.

– Gearless drive: Home elevators using this type of drive systems come closest to being called a “green elevator” as it uses amazingly less amount of energy. This phenomenal achievement is made possible by the use of a gearless motor and a counterweight equivalent to 40% more than the weight of the cab. They are also low maintenance, are whisper quiet in their operation and most energy efficient as compared to the other drive systems.

Before the installation of a home elevator, it is very important to understand the different types of drive systems which come along with these elevators. Only then will it be possible to install the required elevator in the house within your specified budget.
