Dewald chain drive truck


Recommended Posts

I thought I'd post this while waiting for an update on the Thornycroft test drive. We finally picked up our new restoration project, a Dewald KL truck. It has been modified with tyres in 1941 and is in quite good condition. Here are a few pictures, will post more next week.

Regards

Marcel

I don't know the exact year, but should be about 1920-25. It was originally on wooden wheels with solids, there is one other survivor known, at the Fondation Berliet in Lyon. It is really in a very good condition.

Dewald supplied trucks to the french government during the war, but also in the years after they had substantial contracts for military use and from building contractors. As the article in CU says, they must have been prisoner of their own concept and when the time came to modernize they missed the boat. Charles Dewald is considered as the inventor of the hydraulic tipper. If you look up his name in google patents you'll find a patent of a hydraulic ram, US 1.237.309, where oil is supplied through hollow journals. This is obviously done in order to avoid the use of a hose, which back then could not withstand the high pressure. The hydraulic system of my truck has disappeared but you can steel see the holes where the ram was fitted and the pto on the gearbox.

Nothing has been done to the Dewald yet. It sits in our shed in a strategically positioned way as it is in my view during breakfast (when I'm home). There is a tag on the engine that says it has been modified for the use with a wood gasser by Michel Coasnès. I found an old note of this company that says 'spare parts of my own fabrication adaptable to Dewald and all types of Laffly trucks'

I am guessing that this company also did the modification of the rear wheels (and probably the fronts). The truck will be restored mechanically only, and for now we will leave the tyres.
