Two numbers appear on every lift quotation: capacity and speed. Capacity is how much the lift can carry. Speed is how fast the cabin travels. Choosing them correctly makes the difference between a lift people love and one they complain about. Here is how to think about both without needing an engineering degree.
What is lift capacity?
Capacity is the maximum load the lift is designed to carry, usually shown as a weight and as a number of persons on the sign inside the cabin. A larger capacity means a larger cabin and a stronger drive. It must never be exceeded.
What is lift speed?
Speed is how fast the cabin moves between floors. A higher speed reduces travel time in tall buildings, but it requires more powerful equipment and still must feel smooth and safe. Very high speed is unnecessary for a short building.
Factors that decide capacity
- Number of people at peak times. More people at once means a bigger cabin or more lifts.
- Type of users. Families with prams, elders with walkers or wheelchair users need more room.
- Goods. Luggage, furniture, trolleys or stock need extra capacity and a larger cabin and door.
- Building type. A home, an apartment, an office and a hospital have very different needs.
Factors that decide speed
- Number of floors and total travel height. More floors need higher speed.
- Waiting time targets. Offices and large apartments want short waits.
- Comfort. Speed must match smooth acceleration and braking.
- Cost. Faster lifts cost more to buy and maintain.
| Building | Capacity thinking | Speed thinking |
|---|---|---|
| Home or villa | Compact cabin; larger if a wheelchair is likely | Modest; comfort matters more than speed |
| Small apartment block | Cabin for several people plus prams and luggage | Moderate |
| Large apartment tower | Larger cabin and several lifts, plus a service lift | Higher, as floors increase |
| Office building | Sized for peak arrival and lunch traffic | Higher, with smart dispatch for short waits |
| Hospital | Bed and stretcher cabins | Smooth and reliable more than fast |
The number of lifts matters as much as their size
Two medium lifts often serve a building better than one large lift, because they reduce waiting and give you a backup when one is under maintenance. Read our guide to planning lifts for apartment buildings and offices and commercial complexes.
A simple way to start
- Count floors and note floor-to-floor height.
- Estimate the people using the lift at peak times.
- List special needs: wheelchairs, prams, goods, beds.
- Share these with your installer and ask for a recommendation with reasons.
Your installer or lift consultant does the detailed calculation. See our passenger lifts, apartment lifts and home lifts.
