A lift has a designated service life - usually 25 years. Once it expires, you need either an expert inspection followed by modernization, or a complete replacement of the equipment. The choice between the two depends not on age but on the condition of specific components.
When modernization is enough
- The shaft, guide rails and load-bearing steelwork are in satisfactory condition.
- The traction machine is in working order, and worm gear wear is within limits.
- The main problem is an outdated controller, doors or car interior.
- You need to add remote monitoring and variable frequency control, while the mechanical parts still have service life left.
When full replacement makes more sense
- The traction machine, car and counterweight are all worn at once - modernization would cost 70-80% of a new lift.
- You need to change the rated load or the type of lift.
- The equipment has been discontinued and spare parts are practically unavailable.
- The lift comes from a producer you no longer want to deal with, in particular from Russia or Belarus.
Will the shaft need rebuilding
In most cases, no. Modern lifts are selected to fit the existing shaft dimensions, so no major building work is needed. The exception is a change in rated load or a switch to a hospital lift with a longer car: then the shaft may need to be widened or the pit deepened.
How long it takes
| Stage | Approximate duration |
|---|---|
| Inspection and equipment selection | 1-2 weeks |
| Manufacturing and supply | 2-4 months |
| Dismantling the old lift | 3-7 days |
| Installing the new lift | 2-4 weeks |
| Commissioning and testing | 3-7 days |
The total time from order to start-up is approximately 3-5 months, and most of it is taken up by manufacturing the equipment rather than work in the building.
