Quick summary
A goods lift is usually sized to the trolley in use on the day it is specified, which is why so many of them are undersized within two years. The failure is rarely mechanical. It is that nobody asked what the operation would look like at capacity, on a delivery day, with a change of tenant. This article is about sizing a goods lift against real operations rather than a catalogue, and the three questions that prevent most of the errors.
The goods lift is sized by the wrong person#
Back-of-house transport is usually specified by whoever is fitting out the space, and they size it to what they can see.
They can see a trolley. They cannot see the tenant who arrives in three years with a different delivery format, the peak week before Christmas, or the pallet that arrives because a supplier changed its packaging.
A goods lift is a permanent structural decision made on temporary information. That is the whole problem in one sentence.
What a goods lift actually has to do#
A goods lift carries goods, and a trained operator usually travels with them. That is the difference from a dumbwaiter, which carries goods only, and from a freight lift, which takes pallet and trolley loads at a scale the goods lift cannot.
Most specifications never distinguish those three, which is why the first quote often solves the wrong problem.
Our freight elevator service covers the heavy end of the range, and the service lift service covers the middle. A goods lift sits in that middle band, and getting the band right matters more than getting the model right.
The three questions that prevent most goods lift errors#
What is the heaviest single item that will ever go in it, not the average load. Average loads are the reason goods lifts fail. The specification needs the worst realistic item, including the delivery that arrives on a pallet because the packaging changed.
What is the peak movement rate, in movements per hour. Duty cycle determines the equipment grade. A goods lift sized for four movements a day will not survive forty, and it will not tell you that until the warranty has expired.
What does the receiving space look like at each end. A goods lift that opens into a corridor narrower than the lift car is a goods lift that cannot take its own largest load. Door configuration and approach clearance belong in the brief, not in the shop drawings.
Sizing a goods lift against the operation#
The useful way to specify is by operation, not by capacity.
| Operation | Wrong default | Better first question |
|---|---|---|
| Supermarket back of house | Goods lift sized to a standard cage | What cage arrives on the busiest delivery day |
| Hotel housekeeping | Sized to average linen volume | What happens on a turnaround day |
| Hospital logistics | Sized to a trolley | Does any load need a controlled route |
| Restaurant multi-level | Chosen by the fit-out contractor | Does the waste leave the same way the stock arrives |
| Warehouse mezzanine | Mezzanine lift chosen on price | Is the load a pallet or a parcel |
The right-hand column is where the money is. None of those questions can be answered by a supplier, because each one is a question about the operation.
What drives the cost of a goods lift#
The machine is a minority of the cost, and it becomes a smaller minority as the load increases.
Structure dominates. A goods lift carrying heavy loads needs floor reinforcement, a pit, and headroom, and those are building costs rather than equipment costs. Door configuration is next, because a wide opening in a load-bearing wall is a structural event.
Then the interface work: power, isolation, fire sealing, and the reinstatement around the openings. Then the ongoing servicing obligation, which sits with the owner for the life of the building and which almost never appears in the fit-out budget.
Ask for the installed cost and the ten-year cost. The goods lift with the lowest purchase price is frequently the most expensive to own.
The specification failure that costs the most#
Every goods lift failure I have seen in hospital and healthcare projects shares a shape. The device works. The operation outgrew it.
That is not an equipment fault, and no supplier will describe it that way. It is a specification fault, and the only defence is to specify against the operation’s worst case rather than its average case.
What to put in the brief#
- The heaviest single item, with dimensions, not just weight.
- Peak movements per hour, and peak day per year.
- Door configuration and approach clearance at both ends.
- Who operates it, and whether they are trained.
- Structural capacity below the pit and above the headroom.
- Twenty-year servicing exposure, and who holds it.
Why a goods lift decision benefits from independent review#
A goods lift sits inside a fit-out, which means it competes for budget with everything visible to a customer. That is exactly why it gets undersized.
The case for independent review is not the purchase price. It is that a goods lift is the one part of a fit-out that cannot be economically changed afterwards, and the cost of getting it wrong is borne for twenty years by an operation that did not choose it. Our independent lift consulting service treats goods lift sizing as part of a wider vertical transport brief, alongside passenger lifts, service lifts, freight capacity and escalators.
The clients who engage this practice repeatedly tend to say the same thing: the value was in the questions asked before the tender, not the price achieved after it.
