Quality And Integrity Of Parts: Can You Be Completely Sure?

(OCTOBER 2015)


The choice of suppliers for elevator components and electronics has grown rapidly over the past decade. One such search on Google reveals hundreds of suppliers from California to China offering replacements and repairs for a fraction of the cost of a new part - but can you ever be sure of the quality and the integrity of these products and services?


The choice of suppliers for elevator components and electronics has grown rapidly over the past decade. One such search on Google reveals hundreds of suppliers from California to China offering replacements and repairs for a fraction of the cost of a new part - but can you ever be sure of the quality and the integrity of these products and services?

 

The staff at NDC are often called upon by our customers to test units that have been purchased from, or repaired by companies that claim to be specialists. In reality, many of these outfits are simply general electronic repair companies looking to 'have a go' and 'cash-in' on the demand for these highly specialised and complex products.

 

NDC were recently called out to investigate and report on a drive that had been submitted for repair to a UK-based electronics repair company operating in the elevator industry.

 

Following problems at site the service company tested the elevator safety circuit and found that it was not operating correctly. Removing the unit to our local service centre, NDC engineers then subsequently traced the fault back to a 'modification’ that had been made to a safety relay by the repair company.

 

When confronted with the evidence, the repair company simply stated that “we didn't think it was important, its only a relay - and we couldn't get hold of a new one so we bypassed it”

 

NDC have been supporting and supplying the elevator OEM’s and the independent service sector for over 15 years. We have reversed engineered and developed TEST - DIAGNOSE - REPAIR - TEST application-specific repair routines for all the elevator components and parts that we repair or supply.

This means that NDC's products and services are not only completely reliable, but moreover - they are safe.
