| Lift technology | Traction lift | Uses a motor-driven sheave and suspension system, commonly with a counterweight. Some residential models are designed without a separate machine room. | Compare available shaft space, headroom, pit requirements, ride performance, maintenance needs, and the proposed rescue procedure. |
| Lift technology | Hydraulic lift | Raises the car using a hydraulic system. The installation may require space for hydraulic equipment; layout and system design vary. | Ask about equipment location, noise, service access, fluid containment, energy use, and what happens during a power failure. |
| Lift technology | Screw-drive lift | Moves the car using a screw-and-nut drive arrangement. Available travel, speed, capacity, and enclosure requirements depend on the specific design. | Request the manufacturer’s technical drawings and compare operating noise, travel limits, maintenance schedule, and accessibility dimensions. |
| Rated capacity | People and mobility equipment | Check the lift’s stated rated load in kilograms or pounds. Account for the intended occupants, a wheelchair or other mobility aid, and any accompanying person. | Do not select by passenger count alone. Confirm that both the rated load and usable car dimensions suit the expected users. |
| Accessibility | Car or platform size | Measure usable interior width and depth, door opening, and turning or entry space. Dimensions required for accessibility depend on the applicable standard and lift category. | Test the proposed layout with the actual wheelchair or mobility device. Include space for an attendant if one may travel with the user. |
| Accessibility | Landing and approach | Check the clear route to each landing, door clearance, threshold or sill, maneuvering space, and any change in floor level. | Review every floor plan, not just the lift car. Have a qualified professional assess access requirements for the home and jurisdiction. |
| Doors and entry | Door operation and protection | Confirm door interlocks, obstruction detection, and the specified door-opening arrangement. Features and required protection vary by lift design and code. | Ask how the doors respond if an obstruction is detected and whether the controls are usable by people with limited reach or dexterity. |
| Safety | Emergency communication | Verify the supplied alarm and communication method, power arrangements, and who receives an emergency call. | Confirm that the communication method works from inside the car and that household members know how to use it. |
| Safety | Power failure and rescue | Ask whether the design includes emergency lighting, backup lowering or another rescue provision, and what conditions apply to its operation. | Obtain written instructions for power outages and entrapment. Rescue and maintenance procedures should follow the lift maker’s instructions and local rules. |
| Safety | Protective systems | Confirm which applicable safeguards are included, such as landing-door interlocks, braking systems, overload detection, and other protections required for the selected design. | Request the compliance documentation and a clear explanation of the safety devices; do not assume every lift type has identical equipment. |
| Installation planning | Building fit | Check shaft or enclosure dimensions, pit depth, overhead clearance, structural loads, electrical supply, and access for installation and servicing. | Use site-specific drawings and a structural review where needed. A product’s nominal dimensions do not by themselves establish that it will fit the building. |
| Local codes | Applicable lift and building rules | Requirements depend on location, lift classification, building type, and intended use. Examples of standards used in some jurisdictions include ASME A17.1/CSA B44 in North America and EN 81 series standards in Europe. | Ask the local authority having jurisdiction which rules apply, whether permits or inspections are required, and which standards the proposed lift is designed to meet. |
| Local codes | Accessibility rules | Accessibility provisions differ by country and by whether a building is private, public, or otherwise regulated. Some accessibility standards specify lift controls, signaling, and dimensions for particular lift categories. | Do not assume public-building accessibility rules automatically apply to a private home—or that private installations are exempt. Confirm the local requirements before design approval. |
| Ownership and upkeep | Inspection and maintenance | Check the required inspection interval, maintenance tasks, service access, and availability of qualified local technicians. | Compare the documented maintenance plan and expected service needs alongside the purchase price. |
