Hi Argie,

Thanks for sharing your video. We have a coal powerplant here in my town, too. But size wise, the have a Liebherr PR754 coal dozer on the pile. This 45 ton machine is sufficient. And here we have three... No, wait! FOUR CAT 657s used to maintain the pile.

They can load, haul, spread and compact without any help. I'm not aware of any 657s in Germany right now. And also at the peak of our highway construction in the 1960/70ies, they were a rather rare machine. Love the drive by of the four in a row, they are huge.

But why exactly are they shifting the coal? The coal pile looks much flatter than the one I am used to see here, maintained by a D8 class dozer. I always thaught, coal scrapers are loaded from the top and then haul it away.

Is this powerplant in the UK? (writing from my phone and can't read any comments on YouTube right now).

Best regards
Max

Hi Max,

Thank you for your reply.
Unfortunately, these scrapers have now gone as the power station now uses biomass instead of coal to generate electricity.
The coal is kept compacted by the scrapers moving the material around the pad and off the top of the pile to the intake screw.
They said the compaction removes air pockets and the chance of spontaneous combustion and fire on the pile.
There was a D9 with large coal blade operating here too, but not on the day I was there!
If I remember correctly the plant took in over 3000 tonnes of coal per week so needed the large scrapers to handle and then re-handle the material efficiently.
