Every home elevator has a drive system of some sort. The drive system is the mechanism that powers and controls the movement of the elevator car up and down.
Several different types of drive system are available today, to address the diverse needs and constraints of elevator installations. While most home elevator drive systems require some space for controls, there are differences in the cost, comfort, and space needed to locate electrical/electronic and mechanical equipment for the elevator depending on its drive system.
Roped Hydraulic Drive
The holeless roped hydraulic drive is the quietest, smoothest drive system available and features a 1:2 roping which allows the hydraulic jack to serve taller spaces without worrying about in-ground drilling or environmental hazards.
The roped hydraulic drive is available in capacities of 950 lbs and 1400 lbs.
Inline Gear Drive (IGD)
The Symmetry IGD is an economical and space saving drive option. Counterweights are supported by chains which are driven at the top of the rail system by an inline gear motor, resulting in the ability to fit in compact overhead spaces.
The IGD system is available for capacities of up to 950 lbs.
Winding Drum Drive
The Winding Drum option provides a balance between ride quality and economy. This drive system type is not commonly used in traditional home elevators, but is common in shaftless home elevators, also known as home lifts. Ropes are wound around a drum which is driven by an electric motor.
The winding drum drive system is available for a maximum capacity of between 350 to 550 lbs.
