Diverse types of Residential Elevators

Residential / Home Elevators come equipped majorly with five different types of drive systems. They are:

• Roped hydraulic residential elevators : Roped hydraulic residential elevators are based on a hydraulic pump that is connected to a piston and pulley. The piston is sustained by a pedestal and connected to the hoist way by a set of brackets. A pair of steel cables are fixed to the floor of the shaft, stretched around the pulley at the top, and then attached to the bottom of the L-shaped sling on which the cab sits. This makes for a smoother ride than many other systems.
• Pneumatic Vacuum Elevator : PVE do not require cables or pistons, but use the hoist way as part of the lifting system. This is necessary to maintain precise atmospheric pressures above and below the cab. The lifting process starts when pressure is reduced above the cab, causing it to start to fill the void. To slide, a control valve slowly releases pressure, creating a cushion of air beneath the cab. Energy is needed almost exclusively to lift the cab and not to lower it.
• Winding Drum and Counterweight Chain Elevator : Winding drum and counterweight home elevators use the age-old design based on a revolving winch and counterweight. The electric motor winds the cable through the drum, alternately raising and lowering the cab and counterweight.
• Traction Drive Elevator Systems : These are seen in the residential space on rare occasion. They are much typically seen in commercial systems.
• Gearless Drive : These are also called green elevator as it uses less amount of energy.
