| 1 | Building Layout and Available Space | Is there a suitable machine-room location, overhead clearance, pit, and shaft area? | Confirm shaft dimensions, pit depth, overhead height, entrance width, and structural load limits before selecting equipment. | Machine-room-less traction systems can reduce dedicated room requirements, but they still need compliant access, maintenance clearance, and adequate structural support. |
| 2 | Rated Capacity | How many passengers, wheelchairs, carts, or goods must the lift carry? | Common passenger-lift capacities range from approximately 450 kg to 2,000 kg; higher capacities may be required for hospitals, freight, or public buildings. | Base the rating on the heaviest expected load, not only the average passenger count. Allow space for mobility devices, service carts, and peak-use conditions. |
| 3 | Travel Distance and Number of Floors | How far must the car travel, and how many stops will it serve? | Traction lifts are generally well suited to multi-floor buildings and longer travel distances. Exact limits depend on local codes and the selected system design. | Longer travel may require additional guide-rail, rope, controller, and emergency-planning considerations. Verify the full travel height rather than counting floors alone. |
| 4 | Speed and Traffic Demand | How frequently will the lift operate during normal and peak periods? | Low-rise buildings may use around 0.5–1.0 m/s, while many commercial or high-rise applications use approximately 1.0–4.0 m/s, subject to design requirements. | Higher speed can reduce waiting and journey times, but may increase installation cost, control-system complexity, energy use, and maintenance requirements. |
| 5 | Energy Efficiency and Operating Pattern | Will the lift make frequent trips, carry uneven loads, or operate continuously? | Variable-speed drives and regenerative systems can improve efficiency, especially in buildings with frequent operation and balanced or heavily loaded trips. | Compare standby power, lighting, ventilation, drive efficiency, and expected annual trips. Energy performance should be evaluated together with traffic performance. |
| 6 | Comfort, Noise, and Ride Quality | Are vibration, stopping accuracy, acceleration, or adjacent-room noise important? | Modern traction systems can provide smooth acceleration and leveling when properly designed, installed, and maintained. | Review controller performance, guide-rail alignment, machine isolation, door operation, and target stopping accuracy. Residential and healthcare projects often require extra attention to noise and comfort. |
| 7 | Safety, Compliance, and Lifecycle Support | Does the proposed lift meet local regulations, inspection rules, and emergency requirements? | Confirm compliance with the applicable local building, accessibility, fire-safety, electrical, and lift-safety standards before procurement. | Evaluate emergency lowering, backup power options, door protection, overload detection, firefighter operation where required, spare-parts availability, inspection access, and long-term maintenance planning. |
