Re: belt drive VS chain drive
It's all about implementation. We had belts on our versachassis WCD last year and we switched to chain because the belts were breaking (they were waaay out of spec. load so that makes sense). The equivalent pitch diameter and width of 25 chain was much stronger and performed fine (24t 9mm belt vs 18t 25 chain).
My experience with chain and belt:
Belt is lighter, do not stretch, are quieter, and more efficient than chain.
Chains requires less precision, are much smaller for the same strength, are much easier to source (especially up here in Canada), can be easily modified to different lengths, have many more available sprocket sizes, you can easily make any sprocket you can't source if you have a CNC mill, and chains can be easily bolted to for a function.
We like the compactness and general ease of use of chain so we decided to use it over belt this year.
