A slightly closer crop on the two cabs and the machine house. This dragline has had an interesting past. It started work in 1971 and continues to this day! It did undergo an incident where it almost slid into the pit. I don’t have the details YET, but I have heard some rumblings about the incident.

Why do Harley Davidson bikes use belt drives instead of chain drives?

Everytime I see a Harley zoom by, I marvel at the fusion of a beautiful cohesive design with precision engineering. One component that catches my eye every time is the belt that delivers power from engine to the rear wheel. It adds value to both the aesthetics and the mechanics.

I wanted to dig deep into the mechanics part of it. Why does Harley use a belt, while most other bikes use chain? What are the tradeoffs of doing so?
