Examination of lifts and lifting equipment

When it is needed

When faults persist after installation, modernisation or servicing and the parties explain their origin differently.

What we examine

Lift equipment
Control and drive components
Documentation and failure history

Materials to prepare

Data sheet and manual
Contract and work completion records
Maintenance and service request logs
Photographs and fault records

Sample questions

Which reported faults are supported by the materials and inspection?
Do the replacement components comply with the equipment documentation?
Which installation defects can be established?
Is the work performed consistent with the repair records?
Which further checks are needed to establish the cause of shutdowns?

How the work is carried out

Study of failure history
Inspection with the maintenance organisation
Comparison of signs and documentation

Result

A report listing established defects and providing a technical analysis of their possible causes.

What affects the conclusions

Testing, switching and access to hazardous areas are agreed with the maintenance organisation. The work does not replace mandatory inspection and certification.

Frequently asked questions

Is access to the machine room needed?

We determine the access required according to the task. The owner arranges it together with the maintenance organisation.

Can a component that has already been replaced be examined?

Yes, if it has been retained and its identity, condition and removal circumstances can be confirmed.

Shutdown and repair history: how to prepare a chronology

For recurring shutdowns, the sequence of events is important. Prepare a table for your enquiry: date and time, lift number, observed manifestation, any dispatcher's record, actions by the maintenance organisation and the result of restoration. Preserve a passenger's report and a control system entry as different sources even when they describe the same episode.

An error code alone does not identify a faulty component. It is compared with documentation for the particular model, the conditions in which it appeared, adjacent events and work performed. It is useful to retain an export of the log in its original format, the controller version and an explanation of the codes. Selected screenshots may omit events preceding the shutdown.

For each replacement, state the designations of the removed and installed components, the date and the document authorising the work.

Separate checking that a replacement occurred from checking whether the original fault was resolved.

Compare complaints before and after repairs: whether the manifestation is the same and whether its frequency and conditions changed.

Retain records, service requests and verification results together with a note of their source.

Questions that can be checked may include: do recurring messages relate to a single technical event; are the submitted data sufficient to assess the repair outcome; which possible causes need checking during inspection? Access to equipment and retrieval of records are arranged through the owner and maintenance organisation. Independent restarts and interference with safety devices to reproduce a failure are unacceptable.
