Yet another obscure device for unloading wood fuels from silos:
Alimentée selon le projet par un système vérin poussoir ou dans le cas d’un combustible maitrisé (réf G20 à G50) par une vis, elle est compatible avec tous types de transferts (vis ou convoyeur) depuis un silo à **échelles racleuses** ou des systèmes à désileurs planétaires et bras articulés.
I've come across ladder scrapers on various sites but these have all been translated from French, so I'm somewhat dubious. I've asked for a picture, but nothing forthcoming yet.
Many thanks again

Only a few days ago I came across gratteur and jeteur, in the context of storage of crushed rock for making cement, and they turned out to be "reclaimer" and "scraper" respectively. These may be related.

Le fond racleur ou échelles racleuses
(Cf. schéma de principe dune chaufferie de moyenne à forte puissance ci-dessus.)
Il se compose d'échelles placées à plat, au sol, au fond du silo. Ces échelles, par un mouvement de va et vient alternatif, extraient le combustible jusqu'au système de transfert. De là, le combustible suit le même chemin que pour le dessileur rotatif.
Ce type de déstockage est utilisable dans tous les projets. Il est cependant plus coûteux que les systèmes rotatifs. Il sera donc majoritairement utilisé dans les cas suivants :

This is the best I can come up with. However, there is a nice picture of them at: http://www.ofme.org/bois-energie/chaudieres.php and a description:
"Il se compose d'échelles placées à plat, au sol, au fond du silo. Ces échelles, par un mouvement de va et vient alternatif, extraient le combustible jusqu'au système de transfert. De là, le combustible suit le même chemin que pour le dessileur rotatif."

Note from asker:
Brilliant site, Chris - many thanks! I see Alex has come up with the same reference too. So much better when you can actually see a picture of what's going on! |
Discussion
As opposed to a sliding frame, A variation in the design is the ‘walking floor’ type. This consists of a flat silo floor frame divided into several strips, which oscillate alternately to and fro alongside each other. At one end of the assembly there is a clearance down which solids fall on to a screw conveyor.
