Shaft surveying for elevator companies

Twenty minutes from arriving on site to a shaft PDF you can order from.

From the moment the technician reaches the building to the moment the PDF lands — pit, travel, headroom and the narrowest clear width, measured automatically by the web app — about twenty minutes pass.

Nobody in that chain needs technical measuring skills.

The whole job, four steps

Arrival to PDF · about 20 minutes

STEP 01

Scan from the landing

Open the app, name the project, hold the phone at the shaft entrance and move steadily. No shaft entry, no ladder, no second visit.

STEP 02

It uploads itself

The scan syncs to the web platform as soon as there is a connection. If the basement has no signal, it waits on the device and sends later.

STEP 03

The platform measures

Pit, travel, headroom and the narrowest clear width are taken off the model automatically. Anything else you need, you measure by clicking two points.

STEP 04

PDF out, order in

Export the shaft sheet or send it straight to an engineer. That document is what the lift gets ordered against.

Laser accuracy, with the evidence attached.

A laser gives you a number. It does not give you the shaft. 3DLiftLens keeps the photorealistic model behind every dimension, so a measurement can be checked, re-taken or questioned months later without anyone driving back to the building.

And the narrowest point of the shaft — the one that decides the car — is recorded automatically instead of being hunted for by hand.

Tape & laser

Numbers on a notepad. Trust the person who took them.

3DLiftLens

Numbers with the shaft attached. Re-measure any time, from anywhere.

The measurement nobody takes

A tape measure reads the shaft where a person can stand.

3DLiftLens reads it every 10 cm over the whole height and reports the narrowest one it finds. On our own test shafts, the widest and the narrowest point were 5 to 15 cm apart.

Those centimetres are the car that comes back.

one reading every 10 cm, over the whole height

Where it does not work yet

In a shaft already full of equipment, one of our five test scans could not be located automatically. You still get the model and the measuring tools — but the automatic figures need a shaft the scan can actually see.

The deliverable

This is what comes out.

Not a 3D model for someone else to interpret — a survey sheet with the figures already taken, the narrowest point already found, and a link back to the scan they came from.

Narrowest clear opening: 1.68 m × 2.19 m, at 1.10 m above the lowest stop.

Furthest out of true: 1.8° against the pit — 0.04 m at the corners, at 0.00 m.

Read from the scan itself, not from a measurement drawn by hand.

Staircases and stairlifts

A staircase is surveyed the same way

Set the phone to Staircase and inclined lift, walk the stairs once, and the platform finds the steps by itself. What comes out is a Stair survey PDF with the dimensions a stairlift is ordered against — not a 3D file for someone else to interpret.

It happens in the building. The staircase appears in 3D on the phone before you leave, and if there is no signal the scan waits and sends itself when there is.

What it finds on its own

The number of steps, and the total rise from floor to floor
Riser height — the average, and the smallest and the largest, so an uneven step shows up
The incline of each straight run
Every turn: the angle, the direction, and the inner and outer radii
The narrowest clear width along the whole flight
The length of the path the rail has to follow
Clear height above the stairs, when the ceiling is in the scan
A table, step by step

What you hand over

Stair survey (PDF) — the figures, the drawing and the checks on one sheet

Stair data (CSV) — every step as a row, for your own spreadsheet

From a real staircase

16 steps · 3.54 m floor to floor · riser 20.8 cm, between 20.2 and 21.3 · a straight run at 46.9° · two turns to the left, about 85° and 81° · narrowest width about 85 cm.

What to expect

Heights and widths land within one to two centimetres, turn angles within about five degrees. The report says so, and asks for the critical figures to be confirmed on site. A run steeper than 45° is flagged. Clear height is measured only if you scanned the ceiling.

On the phone, in the office

One app for the field, one platform for everyone else. Scans, dimensions and project history stay in the same place.

Works with no signal

Scans are held on the device and sent automatically when the connection comes back.

Every storey, one model

The whole shaft in a single capture — landings, sills and obstructions included.

Send it on, keep the record

Share a scan with an engineer or a client by link, or export the file. The project stays archived.

In the shaft, and afterwards

A shaft has no reception. The app was built around that.

Nothing depends on a good signal at the wrong moment, and nothing leaves your company unless you send it.

Saved first, uploaded later

The scan is written to the phone before anything is sent. When the signal comes back, it uploads itself.

Uploads with the screen locked

Put the phone in your pocket and drive to the next job. The upload keeps going without you watching it.

Pause, move, carry on

Stop the scan to move the ladder or open the next landing door, then continue. What you captured before the pause stays.

Your link, your decision

A survey is private to your company. It becomes readable from outside only when you create a share link for it.

Not sitting in the Files app

Scans still waiting to upload are hidden from the phone’s file browser, so they cannot be dragged out or deleted by mistake.

The phone tidies itself up

Finished models are cleared from the device after a week. The scan itself stays on the platform, where storage is unlimited.

Built for companies, not for accounts

If your technician leaves tomorrow, what leaves with him?

Every survey belongs to the company that paid for the visit — not to the phone it was taken on. You sign up as a company, with your business address and VAT number, and you decide who can do what.

Technicians without an email address

Give a field technician a username and a password. No company mailbox to create, no personal account, nothing to wait for.

Deleting is a request, not a click

A technician asks; an administrator decides. Nobody removes a survey from the company on their own.

Thirty days to change your mind

Deleted work waits in the bin for thirty days before it is really gone. A wrong click is not a lost survey.

Owner, administrator, technician

Three roles, set per person. Invite someone with a link, change what they can reach, remove them when they leave.

Three kinds of company, around the same survey

Independent lift companies

Quote today, not next week

The owner, the technician and the office all read the same shaft sheet. One survey visit, one document, and a quotation that goes out the same day.

OEMs & multinationals

One survey standard, every country

Field teams of any skill level produce identical, auditable shaft records. Engineering receives the same file from every site, with the model to check it against.

Suppliers & manufacturers

Quote from measurements, not from a phone call

Lift companies send quote requests straight from the survey they took. You see the shaft, the stops and the region before you decide whether to bid.

Three questions this answers

How do I survey a shaft?

What the visit has to produce, and the three ways it is done

What is this costing me?

The measuring, the wrong dimension, and the one nobody counts

How do I order from abroad?

Quote requests made from the survey, not from a redrawn plan

The founding places are taken

Thank you to the companies that came first. They surveyed real shafts while the app was still new, told us what did not work, and everything fixed since was fixed because they found it. Their terms hold until 31 December 2026.

Founding membership is closed. From here on, the annual plans apply.
