Home lift

A Home lift is a specific product that transports people within a space; such as, an apartments, homes, or other private property with multiple stories or uneven flooring. A Home lift is complies with global standards of Machine Directive 2006 42 EC which complies to 194 parameters of safety for a lift to be installed inside a private property.[1]
Home lifts are compact lifts for 2 to 6 persons. Unlike hydraulic lifts or traditional "gear and counterweight" operated elevators, a home lift doesn't require additional space for machine room, over head, or pit, making it more suitable for domestic and private use. Often, maintenance costs are also lower than a more conventional lift.
The driving system for a home lift is often built inside the lift structure itself and features a screw, an electric motor, and a nut mounted behind the control panel of the lift's platform; it is thus referred to as a "screw and nut" system. When the lift is operated, the engine forces the nut to rotate around the screw, pushing the lift up and down. Most home lifts come with an open platform structure to free even more space and grant access from 3 different sides of the platform. This requires all producers to include specific safety mechanisms and, in some countries, to limit the travel speed.[citation needed]
Home lifts have been present on the market for decades, and represent a growing trend. Most common producers are based in Europe, such as the Sweden-based Aritco Lifts AB, active since 1995,[2] British manufacturer Wessex Lift Co. Ltd., active since 1976.[3] Many home lifts producers sell their products through their own network, but it is not rare to see them providing their lifts to bigger elevating system groups. Several lift manufacturers enter new markets like India with customization and installation partners who have scaled up their technical capabilities[4].
Types of home lifts
Cable-driven home lifts
Cable-driven home lifts consist of a shaft, a cabin, a control system and counterweights. Some models also require a technical room. Cable-driven lifts are similar to those found in commercial buildings. These elevators take up most space due to the shaft and the equipment room, so installing a cable system in a new building is much easier than trying to retrofit an existing building. Traction elevators need a pulley system for movement. They are less common for new buildings, as hydraulic technology is used in most cases.
Chain-driven home lifts
Chain-driven home lifts are similar to cable-driven lifts, but they use a chain wrapped around a drum instead of a cable to raise and lower the car. Chains are more durable than cables and do not need to be replaced as often. Chain-driven home lifts also do not require a separate machine room, which saves space.
Machine room-less home lifts
Machine room-less home lifts operate by sliding up and down a travel path with a counterweight. This type is an excellent choice for existing residential buildings, since neither machine rooms nor pits reaching into the ground are required. However, traction elevators still require additional space above the elevator roof to accommodate the components required to raise and lower the car. Shaftless home lifts consist of a rectangular elevator cabin positioned on a rail. The lift travels on the route from the lower floor to the upper floor and back.
Hydraulic home lifts
Hydraulic home lifts are driven by a piston that moves in a cylinder. Since the drive system is completely housed in the elevator shaft, no machine room is required and the control system is small enough to fit into a cabinet on a wall near the elevator. For hydraulic systems with holes, the cylinder must extend to the depth of the floor corresponding to the feet of the elevator, while hydraulic systems without holes do not require a pit.
Pneumatic home lifts
Pneumatic home lifts use a vacuum system inside a tube to drive their movement. A pit or machine room is not required, so pneumatic home lifts are easiest to retrofit into an existing home. Pneumatic lifts consist of acrylic tubes or glass (typically about 80 cm in diameter). It look like a mail tube you may know from films or older buildings. Pneumatic elevators are not hidden in the wall and are normally placed in the near to a staircase. [5]
