This is what a buyer checks before they shortlist a machinery and equipment supplier.
What does a developer check before selecting an elevator supplier?
They check capacity and speed against the traffic study, shaft and pit dimensions against the building, and code compliance for the jurisdiction. Then maintenance terms, because the service contract usually outlives the installation contract by decades and costs more.
A developer is choosing equipment whose maintenance contract will bind the building's owners for twenty years.

What does a developer check before selecting an elevator supplier?
What a buyer needs to identify the product
These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Product type and application
Passenger, goods, home and escalator products differ entirely.
- 2
Rated load and speed
Determined by the building's traffic requirement.
- 3
Shaft, pit and headroom requirements
Constrains the building design.
- 4
Machine room requirement
Machine-room-less designs change the building layout.
- 5
Travel height and number of stops
Defines the installation.
- 6
Code and standard compliance
Determines legality in the jurisdiction.
- 7
Door types and finishes
The visible part the client actually chooses on.
The documents buyers ask for
Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Technical specification and shaft drawingAsked at: building design stage | Dimensions, loads and clearances the building must provide | Publish it |
| Code compliance certificationAsked at: before commissioning — legally required | Conformity with the lift safety standard for the jurisdiction | Publish it |
| Type examination certificateAsked at: regulatory approval | Approval of the safety components and design | Publish it |
| Traffic analysisAsked at: design stage | That the specified configuration meets the building's demand | Name it, share on request |
| Installation and commissioning test recordAsked at: handover | Safety tests performed before handover | Per shipment |
| Maintenance contract termsAsked at: before selection — this is the long-term cost | Scope, frequency, response times and price escalation | Publish it |
| Spare parts availability commitmentAsked at: life-cycle assessment | How long parts remain available for the model | Publish it |
Where elevators and escalators sites lose the enquiry
Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.
Maintenance terms not addressed before purchase
The service contract is where the money is over twenty years. A supplier silent about it in public is assumed to be relying on the customer not asking.
Shaft requirements not published
The architect needs them early. A supplier whose dimensions are not available is designed out before being considered.
Proprietary components not disclosed
Buildings are stuck with the maintenance provider when components are proprietary. Buyers who have experienced it check specifically, and honesty here wins the informed ones.
What the enquiry form should ask
A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.
Enquiry form — elevators and escalators
Enough to reply usefully, short enough that a buyer finishes it.
- Building type and traffic requirement
- Determines the specification.
- Travel height and number of stops
- The core configuration.
- Shaft dimensions available
- Constrains what can be installed.
- Code and jurisdiction
- Decides compliance requirements.
- Finish and specification level
- Drives the visible cost.
- Programme and handover date
- Lift installation is on the critical path.
Questions suppliers ask
Should maintenance pricing be discussed before installation?
It should be published, or at least explained, because it is most of the lifetime cost. Buyers increasingly evaluate installation and maintenance together, and a supplier who is transparent about the long relationship wins against one who is quiet about it.
How much does proprietary technology matter to buyers?
Increasingly a great deal, because it determines whether the building can ever change maintenance provider. Stating plainly which components are proprietary and what a third party can service is unusual and builds trust with owners who have felt locked in.
What does an architect need earliest?
Shaft, pit and headroom dimensions, machine room requirements and structural loads. These fix the building design, so the supplier whose figures are available at concept stage is frequently the one designed in — often before any commercial conversation.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
