Yeah but what took place that caused them to tell Granby no go for operating on DIesel drive and is that issue now fixed as well? Seems pointless to be replacing the suspected faulty electric drive, only to go back to Diesel drive once electric drive has been replaced, and yet the Tramway people suspended the license last week because of suspected issues with the diesel drive..

Anyone confused here?

Sounds like there are a few different things going on and we don't know what they all are.

I am puzzled over why they are installing a new drive. A new one was installed back in December.
Anything is possible when you don't understand what you are talking about.

Yeah ... if you ever wanted a clear and graphic example of just exactly HOW elastic dynamic events can effect a long wire rope under tension ... jeez ...

Peter's summary is some excellent reporting work, too.

A lot of people are going to read this, and really have to think very hard.

Hello all,
I've recently been having a little back and forth about the competence of this investigation on Remontees-Mecaniques. A person named Velro, described by a moderator as "strange," keeps on making accusations about incompetence and a lack of experts and expertise in North America. The latest claims are right here:

View PostVelro, on 16 May 2017 - 04:06 PM, said:

I highly recommend the reading of the official Granby Ranch Quick Draw Express 4-CLD incident report which can be downloaded as PDF (see link in my previous message).

The aforesaid report clearly shows that no real expert in automation and drives was involved, especially also referring to hands-on experience when it comes to commissioning large DC drives.

Further, the way the accident investigation has beem conducted remains highly questionable. Very common and internationally established procedures have not been respected and several important issues have either not been investigated thoroughly enough or have not even been addressed at all.
Specialists from Leitner, Pilz and ABB should have been involved as the members of the investigation board were patently incompetent in automation and drive engineering.

The whole report cannot be considered as acceptable, especially also due to the unusual nature of the incident. Not even to mention that a lot of non-classified technically relevant information is missing.


A more technical discussion will follow.


As I am not in the industry myself, I wanted to get others reactions to these statements. Here's the original post/thread:

You can scroll up and see I've tried to push back against these claims.
If necessary, posts can be copied and pasted into Google Translate to translate.


I think he just has a "worldview" that North American lift maintenance is inferior to European. But I've run out of things to say.
Is it onto something, is he totally wrong, is he trying to compare apples to oranges, or somewhere in between?

Hmm, perhaps a foreign exchange program could be implemented to bring lift techs from over there over here for a week or two and vice-versa, provides a chance to observe, make notes, ask questions, and then compare things at some sort of summit meeting.

Sounds like he's investigating an air crash.
